Introduction to Microneedling for Hair Growth

What is Microneedling? (Collagen Induction Therapy Explained)

Microneedling is a minimally invasive procedure that involves creating tiny micro-injuries in the scalp using fine needles. These controlled injuries stimulate the body's natural healing response, leading to increased collagen production, improved blood circulation, and activation of dormant hair follicles.

The process is also known as Collagen Induction Therapy (CIT) because it primarily works by boosting collagen and elastin levels in the skin. While originally used for skin rejuvenation to treat scars, wrinkles, and hyperpigmentation, microneedling has gained recognition as an effective treatment for hair loss by promoting new hair growth, increasing follicle thickness, and improving overall scalp health.

Here’s how microneedling for hair works:

The tiny punctures trigger the wound healing process, leading to increased production of growth factors like platelet-derived growth factor (PDGF) and epidermal growth factor (EGF). These are essential for stimulating hair follicles and prolonging the anagen (growth) phase of the hair cycle.
It enhances blood circulation to the scalp, ensuring follicles receive more oxygen and nutrients. Poor circulation is a common cause of hair thinning.
It creates micro-channels in the scalp, allowing better absorption of topical treatments like minoxidil, peptides, or stem cell-based serums, making them significantly more effective.

History & Evolution of Microneedling (How It Became a Haircare Trend)

Microneedling dates back to ancient Chinese acupuncture techniques, but its modern version was first introduced in 1995 by Dr. Desmond Fernandes, a South African plastic surgeon, who used fine needles to improve skin texture. Over the years, dermatologists refined the method, and it became widely adopted in aesthetic medicine for treating scars, wrinkles, and pigmentation issues.

The concept of microneedling for hair loss emerged in the early 2000s when researchers discovered that mechanical stimulation of the scalp could reactivate dormant follicles. A breakthrough study in 2013 compared microneedling combined with minoxidil to minoxidil alone. The results showed that patients who underwent microneedling had significantly better hair regrowth than those using minoxidil without it. This led to a surge in its popularity, and by the late 2010s, microneedling had become a mainstream hair restoration treatment, often recommended alongside PRP (platelet-rich plasma) and mesotherapy.

Today, microneedling is used by trichologists, dermatologists, and hair transplant specialists worldwide as a cost-effective and non-surgical approach to combat hair thinning and mild to moderate androgenetic alopecia.

Benefits of Microneedling for Hair

Microneedling has gained immense popularity due to its multi-layered benefits for hair growth and scalp health. Unlike traditional hair loss treatments that rely solely on medication or supplementation, microneedling activates the body’s natural healing mechanisms.

Here’s how it helps:

Stimulates New Hair Growth: The micro-injuries caused by microneedling activate stem cells in the hair follicle bulge region, triggering new hair formation and prolonging the anagen phase of hair growth.
Increases Collagen Production: Collagen strengthens hair follicles and maintains a healthy scalp environment. With age and environmental damage, collagen levels drop, leading to hair thinning. Microneedling reverses this process.
Enhances Blood Circulation: Poor blood flow to the scalp starves hair follicles of essential nutrients and oxygen, accelerating hair loss. Microneedling increases blood vessel formation, improving nutrient and oxygen delivery to the follicles.
Boosts Absorption of Hair Growth Serums: Minoxidil, peptides, and PRP solutions work better when they penetrate deeper scalp layers. Microneedling creates micro-channels that enhance topical absorption by up to 300%, making treatments far more effective.
Reduces Scalp Inflammation: Chronic micro-inflammation of the scalp is a hidden cause of hair loss. Microneedling helps reset the scalp environment by reducing inflammation which is responsible for androgenetic alopecia.
Non-Surgical & Cost-Effective: Microneedling is an affordable and non-invasive treatment with minimal downtime. It is ideal for individuals in the early to moderate stages of hair thinning.
Works on Different Types of Hair Loss: Microneedling is effective for androgenetic alopecia, traction alopecia, making it a versatile adjuvant treatment option with other mainstay treatments for hair regrowth.

Studies continue to explore the long-term effects of microneedling. Still, early evidence suggests that regular sessions (once every 2-4 weeks) can significantly improve hair density, thickness, and scalp health.

Microneedling for Hair Growth & Hair Loss

How Does Microneedling Stimulate Hair Growth?

Microneedling stimulates hair growth by creating controlled micro-injuries on the scalp using fine needles, which in turn triggers the body's natural healing response. This process enhances collagen production, increases blood circulation, and activates dormant hair follicles, making it a powerful adjuvant tool for combating hair thinning and promoting regrowth.

There are two primary mechanisms through which microneedling works for hair growth:

Activation of Growth Factors
- The micro-wounds created by the needles stimulate the release of essential growth factors, such as platelet-derived growth factor (PDGF) and vascular endothelial growth factor (VEGF). These factors boost follicular regeneration, strengthening existing hair and promoting new hair growth.
Increased Blood Circulation
- Poor blood flow is a common cause of hair loss. Microneedling increases capillary formation and oxygen supply to the hair follicles, nourishing them and extending the anagen (growth) phase of the hair cycle.
Enhanced Absorption of Topical Treatments
- Microneedling significantly improves the penetration of minoxidil, peptides, and DHT blockers by up to 300%, ensuring that these treatments reach the deeper layers of the scalp where hair follicles reside.

Dermarollers vs Professional Microneedling

Dermarollers are handheld devices with microneedles (typically 0.5mm to 1.0mm depth) that users can roll over their scalp at home. They help with mild hair thinning but have less precision compared to professional microneedling.
Dermapens and automated microneedling devices used by dermatologists provide consistent needle depth of 1.5mm or more, reduced trauma, and better safety measures, making them more effective for stimulating hair regrowth.

Microneedling vs PRP for Hair Loss: Which Is Better?

Microneedling and PRP (platelet-rich plasma) therapy are both non-surgical hair restoration treatments, but they differ in their approach and effectiveness.

Microneedling

Uses micro-injuries to stimulate collagen production and activate hair follicles
Can be done with or without topical treatments (minoxidil, peptides)
Improves scalp blood circulation and reduces fibrosis, making it effective for early-stage hair thinning

PRP (Platelet-Rich Plasma)

Involves drawing the patient’s blood, extracting platelet-rich plasma, and injecting it into the scalp
Contains high concentrations of growth factors that help stimulate dormant follicles
More effective for moderate to severe hair loss, particularly in androgenetic alopecia

Which One Should You Choose?

For early-stage thinning or mild hair loss, microneedling alone or with minoxidil can be effective.
For significant hair thinning or dormant follicles, PRP is often more effective.
For best results, dermatologists recommend combining PRP with microneedling, as the micro-injuries increase PRP absorption and enhance its effectiveness.

How Often Should You Do Microneedling for Hair?

The ideal frequency of microneedling depends on needle depth and scalp sensitivity:

0.5mm Dermarollers (At-home use) – Twice a week for mild stimulation
1.0mm Dermarollers – Once a week, as deeper penetration requires longer healing time
1.5mm Professional Microneedling – Once every 2-4 weeks for best results
2.0mm Needles – Only used in clinical settings for severe hair thinning

Overusing microneedling without proper recovery time can cause scalp irritation, excessive inflammation, and counterproductive damage to hair follicles. Following post-treatment care (avoiding harsh shampoos, sun exposure, and excessive scalp touching) ensures optimal regrowth results.

Does Microneedling Work for Bald Spots? (Before & After Insights)

Microneedling is effective for hair thinning and mild-to-moderate hair loss but not a cure for completely bald spots with no active follicles.

Who can benefit from microneedling?

People with androgenetic alopecia (pattern hair loss) can see improvement in hair density and thickness as the blood circulation becomes better leading to better scalp environment and follicle reactivation.

Who may not see results?

Completely bald areas (Norwood 5-7 stage hair loss) where follicles are permanently miniaturised.
Cicatricial (scarring) alopecia, where inflammation has destroyed hair follicles beyond repair.

Before-and-after results from clinical studies show that patients with early-stage balding experience noticeable improvement after 3-6 months of regular microneedling treatments, when used as an adjuvant therapy.

Before-and-after results from clinical studies show that patients with early-stage balding experience noticeable improvement after 3–6 months of regular microneedling treatments, when used as an adjuvant therapy.

However, it’s important to consult a qualified dermatologist to assess the root cause of your hair loss and determine whether microneedling is the right treatment for your condition.

Microneedling for Hair Growth at Home: Is It Safe?

Microneedling can be done at home using dermarollers, but safety precautions are crucial to avoid infections, scalp trauma, or ineffective treatment.

Pros of at-home microneedling

Cost-effective alternative to professional treatments
Can enhance minoxidil or peptide absorption
Easy to incorporate into a weekly hair care routine

Cons and risks of at-home microneedling

Lack of precision – Dermaroller cover large areas but do not penetrate evenly like dermapen or professional microneedling.
Risk of scalp infection if the roller is not properly sanitised
Overuse can cause irritation, leading to increased shedding instead of growth
Not as effective for severe hair loss, as needle depth is limited in home-use devices

How to do microneedling at home safely

Choose a 0.5mm dermaroller for hair growth stimulation
Disinfect the roller before and after every use with rubbing alcohol
Avoid excessive pressure to prevent scalp injury
Do not use on irritated or infected scalps
Combine with minoxidil, peptides, or growth serums for better results

For advanced hair loss, it is recommended to seek professional microneedling treatments as dermatologists use automated devices that provide better penetration, safety, and precision.

Microneedling Procedure: Step-by-Step Guide

Pre-Treatment Preparation: What to Do Before Microneedling

Proper preparation is crucial for maximising the benefits of microneedling while minimising the risk of irritation or infection. Before the procedure, certain steps should be followed to ensure the scalp is in optimal condition.

1-2 Weeks Before Treatment:

Stop using any harsh scalp treatments that could make the skin more sensitive.
If using minoxidil, discontinue its use 48 hours before the session to prevent excessive irritation.

48 Hours Before Treatment:

Wash your scalp with a gentle, sulfate-free shampoo to ensure cleanliness.
Avoid alcohol consumption and blood-thinning medications (such as aspirin or ibuprofen), as they may cause prolonged bleeding.
Hydrate well by drinking plenty of water, as this supports the body's healing response.

On the Day of the Procedure:

Ensure the scalp is clean and dry, free from any hair products or oils.
If undergoing professional microneedling, a topical numbing cream may be applied to reduce discomfort.

Microneedling Procedure Explained

Microneedling is performed using specialised tools that create controlled micro-injuries on the scalp. These injuries stimulate collagen production, increase blood circulation, and activate dormant hair follicles.

Step 1: Cleansing the Scalp

The scalp is thoroughly cleaned with an antiseptic solution to remove any dirt, oils, or bacteria. This step is essential to prevent infection.

Step 2: Application of a Numbing Agent

A topical numbing cream may be applied, especially when using deeper needles (1.5mm or more), to minimise discomfort. It typically takes 15-30 minutes for the numbing effect to take hold.

Step 3: Microneedling with a Dermapen or Dermaroller

A dermapen or automated microneedling device creates tiny punctures across the scalp.
Needle depth is adjusted based on the treated area—1.0mm to 1.5mm for most parts of the scalp and 0.5mm for sensitive areas like the hairline.
The device is moved vertically, horizontally, and diagonally to ensure even coverage.

Step 4: Application of Growth-Boosting Serums

After microneedling, growth factor serums, peptides, PRP, or minoxidil may be applied.
The microchannels created by the needles allow for deeper penetration, enhancing the effectiveness of these treatments.

Step 5: Post-Treatment Care

The treated area is kept clean to prevent infection, and the patient is advised not to wash the scalp for at least 24 hours.

How Long Does a Microneedling Session Take?

The total duration of a microneedling session varies depending on whether it is done at home or by a professional.

At-home microneedling with a dermaroller: 10-15 minutes
Professional microneedling (clinic-based): 30-60 minutes, including numbing time
PRP + microneedling combination: 60-90 minutes, as PRP involves drawing blood and centrifugation before microneedling.

Multiple sessions are required for optimal results, typically spaced every 2-4 weeks, depending on individual hair loss severity.

What to Expect During & After Microneedling?

Microneedling is a relatively simple procedure, but understanding what to expect can help patients prepare mentally and physically.

During the Procedure:

A mild pricking sensation is felt, especially in areas with thinner skin, such as the hairline.
If numbing cream is applied, discomfort is minimal. Without numbing, a slight stinging sensation may be experienced.
The scalp may appear slightly red and irritated immediately after the session which gets normal over a next few hours.

Immediately After Treatment:

The scalp may feel tight, warm, and slightly tender.
Minor pinpoint bleeding may be visible but should subside within minutes.
Patients are advised to avoid touching or scratching the treated area.

24-48 Hours Post-Treatment:

The scalp remains sensitive, and redness gradually fades.
Avoid hair washing, excessive sweating, and sun exposure during this period.
Some individuals may experience temporary shedding (shock loss) as weak hair falls out before stronger and healthier hair start growing.

Microneedling Healing Stages: Day-by-Day Recovery Timeline

Day 1:

The scalp appears red, slightly swollen, and may feel warm.
Mild discomfort is normal, but pain is minimal.
Patients should avoid washing the hair for at least 24 hours to allow micro-wounds to heal.

Day 2-3:

The scalp returns to normal, with most redness fully subsided.
Minor scalp flaking or dryness may appear as the healing process begins.
Itching may occur, but scratching should be avoided to prevent irritation.

Day 4-7:

New hair growth may not be visible yet, but follicles are in the activation phase.

Week 2-4:

Many patients notice reduced hair shedding and slight thickening of existing hair.
At this stage, the scalp is ready for the next microneedling session.

Months 2-3:

Hair density is noticeably improving, with new hair appearing stronger and thicker.
Those using minoxidil or PRP alongside microneedling may see faster and more pronounced regrowth.

Month 6+ (Full Results):

Significant improvement in hair volume and thickness.
Hair loss slows down, and new growth fills in previously thinning areas.
Continued maintenance treatments every 3-6 months help sustain results.

Microneedling is not a one-time solution nor is it a monotherapy but a long-term hair regrowth strategy that works best when combined with proper scalp care, supplements, and other growth-enhancing treatments.

Microneedling Side Effects, Risks & Safety

Is Microneedling Safe for All Hair Loss Conditions?

Microneedling is considered a safe and effective treatment for most types of hair loss, but it may not be suitable for everyone. The procedure works best for androgenetic alopecia (pattern baldness) and thinning following chronic telogen effluvium. However, individuals with certain scalp conditions should consult a dermatologist before undergoing treatment.

Safe for:

Androgenetic alopecia (male and female pattern baldness) – Microneedling increases blood circulation and activates dormant follicles.

Not recommended for:

Cicatricial (scarring) alopecia – Permanent follicle destruction means microneedling may not work.
Active scalp infections – Conditions like folliculitis, fungal infections, or severe dandruff should be treated before microneedling.
Psoriasis or eczema – Can cause flare-ups and worsen inflammation.
Severe baldness (Norwood 6-7) – If follicles are completely dead, microneedling alone cannot regrow hair.

Common Side Effects of Microneedling & How to Prevent Them

While microneedling is minimally invasive, specific side effects may occur, especially if the procedure is not done correctly.

Mild Side Effects (Common & Temporary):

Redness & Scalp Sensitivity – The treated area may appear flushed for 24-48 hours.
Mild Swelling or Tightness occurs due to increased blood flow and collagen stimulation.
Itching or Scalp Dryness – Temporary dryness can occur as the skin heals.
Minor pinpoint bleeding – Small dots of blood are normal but should stop quickly.

Rare Side Effects (If Not Done Properly):

Excessive bleeding or bruising – Using too much pressure or incorrect needle depth can cause unnecessary trauma.
Infections – Poor hygiene or unsterilised tools increase the risk of bacterial infections.
Follicular damage – Overuse can lead to follicular irritation, worsening hair shedding instead of promoting growth.

Prevention Tips:

Use sterilised tools (dermaroller, dermapen) to prevent infection.
Avoid overusing microneedling—once every 2-4 weeks is enough.
Keep the scalp clean and avoid harsh shampoos for 48 hours post-treatment.
Stay hydrated and follow a nutrient-rich diet to support healing.

Does Microneedling Damage Hair Follicles?

One of the biggest concerns about microneedling is whether the needles could harm hair follicles instead of stimulating them. When done correctly, microneedling does not damage follicles. Instead, it creates micro-injuries that promote follicle regeneration.

However, incorrect techniques can lead to unintended damage:

Using needles that are too deep (over 2.0mm) may puncture deeper skin layers, increasing inflammation.
Applying too much pressure can cause scalp trauma instead of gentle stimulation.
Frequent microneedling (more than once a week) can prevent the scalp from healing properly, leading to follicular stress and potential shedding.

When performed at the right depth and frequency, microneedling is safe for hair follicles and enhances their function by improving collagen, blood flow, and growth factor production.

Microneedling Gone Wrong: What Happens If Not Done Correctly?

Improper microneedling techniques can lead to serious complications, negating its benefits. Some common mistakes include:

Using non-sterile needles – Increases the risk of bacterial infections and folliculitis.
Excessive microneedling sessions – Overuse can cause chronic inflammation, leading to increased hair shedding instead of regrowth.
Applying minoxidil immediately after microneedling – Can cause severe irritation and burning due to open micro-channels. It should be used at least 24 hours post-procedure.
Skipping aftercare – Exposure to pollution, sweat, or chemicals too soon after microneedling can lead to irritation or delayed healing.
Doing microneedling on an unhealthy scalp – Conditions like seborrheic dermatitis, psoriasis, or scalp acne should be treated first to avoid worsening inflammation.

Long-Term Effects of Microneedling: Pros & Cons

Microneedling is a long-term hair restoration strategy that offers consistent results when performed correctly.

Pros:

Thicker, denser hair growth over time.
Stronger follicles with improved anchoring in the scalp.
Better absorption of growth serums, minoxidil, or PRP.
Minimal downtime with a fast recovery process.

Cons:

Results are gradual, requiring multiple sessions over months.
Not effective for complete baldness or empty follicles.
Requires maintenance treatments every few months for sustained benefits.
Mild discomfort during the procedure, especially for deeper microneedling sessions.
Risk of overuse-related inflammation if not spaced correctly.

With proper technique, professional guidance, and patience, microneedling can be a powerful tool for reducing hair loss, strengthening follicles, and improving scalp health.

Microneedling vs Other Hair regrowth Treatments

Microneedling vs Low-Level Laser Therapy (Helmet Lasers): Which Is Better?

Low-level laser therapy (LLLT) and microneedling are both non-invasive treatments used to stimulate hair growth, but they work through different mechanisms.

Microneedling creates micro-injuries in the scalp to trigger the body’s natural healing response, increasing collagen production and enhancing blood flow to the hair follicles. It also improves the absorption of topical treatments like minoxidil, peptides, or PRP, making them more effective.

Low-level laser therapy uses red or near-infrared light to stimulate cellular activity within hair follicles, promoting increased ATP production and reducing inflammation. This encourages follicles to remain in the growth phase longer and delays shedding.

Microneedling is a mechanical stimulation method that works well for those with early to moderate hair loss and those using additional treatments like PRP or minoxidil. It is more targeted and requires multiple sessions to see results.

Low-level laser therapy is painless, requires no downtime, and is suitable for those looking for a passive treatment that can be done at home. However, it needs consistent use, and results may take longer to appear.

Microneedling is generally preferred for people with moderate to advanced thinning, while low-level laser therapy is better for those looking to maintain hair density or prevent further shedding. Many dermatologists recommend using both treatments together for enhanced results.

Microneedling vs Mesotherapy: When to Choose What?

Both microneedling and mesotherapy are used to improve hair health and prevent thinning, but they target hair loss differently.

Microneedling stimulates hair follicles through mechanical micro-injuries, which increase blood flow, collagen production, and nutrient absorption. It helps reactivate dormant follicles and works well with topical treatments.

Mesotherapy involves injecting a nutrient-rich cocktail of vitamins, peptides, DHT blockers, and amino acids directly into the scalp. This treatment delivers essential nutrients straight to the hair roots, improving follicular health and preventing miniaturization.

Microneedling is more effective for improving scalp circulation and absorption of external treatments, making it a great choice for those already using minoxidil or PRP. It is also beneficial for those with mild to moderate hair thinning.

Mesotherapy is best for individuals with nutritional deficiencies contributing to hair loss. It provides a direct supply of growth-boosting compounds and is especially helpful in cases of telogen effluvium or diffuse hair thinning caused by stress or poor diet.

Both treatments can be used together, with mesotherapy supplying essential nutrients and microneedling enhancing their absorption.

Microneedling vs Dermarollers: What’s the Difference?

While both microneedling and dermarollers create controlled micro-injuries in the scalp, they differ in precision, effectiveness, and application.

Microneedling performed by a professional uses a dermapen or an automated microneedling device that delivers consistent depth, better targeting the scalp’s deeper layers. This leads to improved follicular stimulation and better absorption of topical treatments.

Dermarollers are handheld tools with microneedles embedded on a rolling device. They are commonly used for at-home treatments, but they do not offer uniform penetration. The rolling motion can also cause unnecessary trauma to the scalp by pulling or tearing the skin if not used correctly.

Microneedling is recommended for those seeking a more controlled, professional treatment that can be combined with PRP or minoxidil. Dermarollers are suitable for maintenance but are less precise and effective in stimulating deep follicular activity.

Microneedling vs Scalp Threads: What Is Better?

PDO threads for hair regrowth is a relatively new hair restoration technique that involves implanting absorbable threads beneath the scalp skin to stimulate collagen production and improve blood flow to hair follicles. These threads help strengthen the scalp structure and enhance hair anchoring.

Microneedling triggers natural wound healing and stimulates growth factors through controlled injuries. It is a less invasive option and does not involve inserting foreign materials into the scalp.

Scalp threads provide longer-lasting stimulation as the threads gradually dissolve over time, offering a more sustained approach to collagen induction. However, this procedure is more invasive and expensive and requires a trained professional to perform it safely.

Microneedling is better for individuals looking for a cost-effective, minimally invasive treatment that can be done more frequently. PDO Scalp threads may be a good option for those seeking long-term improvement in the scalp, particularly in cases of severe thinning.

Microneedling Aftercare & Recovery Tips

What to Do After Microneedling for Best Results?

Proper aftercare is essential for maximising the benefits of microneedling while ensuring a smooth recovery process. Since the procedure creates tiny micro-injuries on the scalp, taking the appropriate steps helps reduce irritation and enhances hair regrowth.

Avoid touching the scalp immediately after the procedure to prevent bacteria from entering the microchannels.
Keep the scalp dry for at least 24 hours to allow healing and prevent infections.
Avoid harsh shampoos, hair styling products, or chemical treatments for at least 48 hours.
Avoid excessive sun exposure and wear a loose-fitting cap if going outside.
Refrain from intense physical activity, saunas, or swimming for the first 48 hours to reduce the risk of irritation and excessive sweating.
Sleep on a clean pillowcase to minimise any contamination that could cause inflammation or irritation.

How Long Does It Take to See Microneedling Results?

Microneedling is not an instant hair regrowth solution but a gradual process that requires multiple sessions. The first signs of improvement are usually seen within a few weeks, with full results appearing over several months.

First few days: The scalp may feel tight, slightly red, or sensitive, but no visible hair growth changes have occurred.
2-4 weeks: Some individuals notice reduced hair shedding and a healthier scalp appearance.
3-6 months: New hair strands appear, and existing hair may look thicker.
6-12 months: Significant hair density and regrowth improvement is seen in those who respond well to treatment.

Consistent microneedling sessions spaced every 2-4 weeks, along with proper scalp care and complementary treatments, yield the best long-term results.

When Can You Wash Your Hair After Microneedling?

Washing the hair too soon after microneedling can irritate the scalp and disrupt the healing process.

It is best to wait at least 24 hours before washing the hair.
Use a gentle, sulfate-free shampoo to avoid harsh chemicals that could inflame the micro-wounds.
Lukewarm or cool water should be used instead of hot water to prevent scalp sensitivity.
Avoid scrubbing or massaging the scalp vigorously for the first few washes to allow healing.

Can You Apply Minoxidil After Microneedling?

Minoxidil is one of the most commonly used hair regrowth treatments, but applying it immediately after microneedling can lead to severe irritation.

Minoxidil should be avoided for at least 24-48 hours post-microneedling, as the microchannels are still open, and direct application can cause burning, redness, and excessive inflammation.
After 48 hours, minoxidil can be gradually reintroduced to the routine, ensuring that the scalp has sufficiently healed.

What Are the Combination Treatments That Can Be Used With Microneedling for Better Hair Regrowth?

Microneedling is not a monotherapy and needs to be paired with other hair growth treatments to enhance results significantly.

PRP (Platelet-Rich Plasma): PRP injections combined with microneedling provide an added boost by supplying growth factors and healing proteins that further stimulate follicle activity.
Mesotherapy: Combining nutrient-rich mesotherapy injections with microneedling helps supply vitamins, peptides, and DHT blockers directly to the hair roots.
Low-Level Laser Therapy (LLLT): Using a laser cap or in-clinic LLLT treatment alongside microneedling improves blood circulation and prolongs the hair growth phase.
Minoxidil: While it should not be applied immediately after microneedling, minoxidil used 48 hours post-treatment can penetrate deeper into the scalp and enhance hair regrowth.
Peptide Serums & Growth Factors: Topical solutions containing peptides, stem cell extracts, or copper peptides can be applied after 24 hours to accelerate follicle regeneration.

A well-structured approach combining microneedling with scientifically backed treatments helps achieve faster and more sustained hair regrowth while improving scalp health.

FAQs: India’s Most Searched Questions About Microneedling

Is Microneedling Painful?

Microneedling causes mild discomfort, but the level of pain depends on the needle depth, technique, and individual pain tolerance.

For at-home dermarollers with 0.5mm needles, most people experience only a tingling or slight pricking sensation.
Professional microneedling using 1.5mm to 2.0mm needles can be more uncomfortable, but topical numbing cream is applied beforehand to reduce pain.
Automated microneedling devices like dermapens cause less trauma than dermarollers, making the procedure more comfortable.

Most people describe the sensation as mild pressure with slight stinging, similar to a deep exfoliation. The scalp may feel sensitive for a few hours post-treatment but should not be painful.

How Many Sessions Do You Need for Hair Regrowth?

The number of microneedling sessions required depends on hair loss severity, scalp health, and additional treatments used.

For mild hair thinning, 4 to 6 sessions spaced every 2-4 weeks can show visible improvement.
For moderate hair loss, 6 to 8 sessions may be needed before noticeable hair thickening occurs.
Ongoing maintenance every 3 to 6 months is required for advanced hair loss after initial sessions.

Dermatologists often combine microneedling with PRP, mesotherapy, or minoxidil to accelerate results. Most patients see early signs of regrowth within 3 to 6 months, with full results appearing after 9 to 12 months.

Is Microneedling Permanent?

Microneedling stimulates new hair growth and improves follicle function, but it is not a one-time permanent solution for hair loss.

Hair regrowth results last 6 to 12 months, after which maintenance sessions are needed to sustain benefits.
If the underlying cause of hair loss is not addressed, shedding may resume once the effects of microneedling wear off.
Combining microneedling with DHT blockers, nutritional support, and proper scalp care helps prolong results.

For progressive hair loss conditions like androgenetic alopecia, microneedling must be done regularly alongside other medical treatments to maintain hair density.

What Should You Not Do After Microneedling?

To prevent irritation and maximize results, certain precautions should be followed after microneedling.

Do not wash your scalp for at least 24 hours to allow the micro-wounds to heal.
Avoid minoxidil or intense topical treatments for 48 hours, as they can cause excessive burning and irritation.
Refrain from sun exposure for 2-3 days, as the scalp will be more sensitive.
Do not scratch or touch the scalp; this can introduce bacteria and lead to infection.
Avoid saunas, steam rooms, and intense workouts for at least 48 hours to prevent excessive sweating and irritation.
Do not undergo other scalp treatments, including chemical dyes or hair spa treatments, for at least a week.

What Is the Best Indication for Microneedling?

Microneedling is most effective for early to moderate hair thinning and works best when the hair follicles are still active. It is indicated for:

Androgenetic alopecia (male and female pattern baldness) – Microneedling improves blood circulation and strengthens miniaturised follicles.
Chronic Telogen effluvium – Helps restore hair density after stress-related shedding.
Poor blood flow – Encourages the formation of new capillaries for better nutrient delivery to follicles.
Post-hair transplant healing – Improves scalp collagen levels, aiding in faster recovery and graft anchoring.

Microneedling is unsuitable for completely bald areas with no viable follicles, active scalp infections, or conditions like scarring alopecia, where follicles are permanently damaged.

For the best results, microneedling should be combined with medical hair loss treatments, scalp care, and lifestyle modifications to maintain long-term hair growth.
