Why Men Lose Hair? Male Pattern Baldness Explained
Published on Fri Apr 17 2026
What is Male Pattern Baldness?
Male pattern baldness is a common type of hair loss in men. It usually begins in the 30s but can start as early as the teenage years. It leads to continuous hair fall without natural regrowth.
Hair loss is most visible around the temples and crown, often leading to a receding hairline and thinning hair. The condition develops gradually over time if left untreated.
How Common is Male Pattern Baldness?
Male pattern baldness, also known as androgenetic alopecia, is very common worldwide. The likelihood increases with age and is strongly linked to genetics, accounting for nearly 80% of cases.
Hair loss patterns may vary depending on age and ethnicity.
Symptoms and Causes
Causes
Male pattern baldness is mainly caused by genetics and hormones. The hormone dihydrotestosterone (DHT), derived from testosterone, shrinks hair follicles and prevents regrowth.
- Genetics (family history)
- Age-related changes
- Lifestyle and diet factors
- Ethnicity variations
Symptoms
- Finer, thinner hair
- Receding hairline
- Hair loss at the crown
- Thinning around temples
- Patchy or circular bald spots
Stages of Male Pattern Baldness
The progression is measured using the Hamilton-Norwood Scale:
| Stage | Description |
|---|---|
| Stage 1 | No visible hair loss |
| Stage 2 | Slight recession near temples |
| Stage 3 | M-shaped hairline, temple hair loss |
| Stage 4 | Receding hairline with crown bald spot |
| Stage 5 | Hairline and crown bald area connect |
| Stage 6 | Significant hair loss at crown and temples |
| Stage 7 | Only thin hair remains on sides |
Diagnosis
Diagnosis is based on hair loss pattern and medical history. Tests may include:
- Dermatoscopy
- Skin biopsy
- Blood tests
- Hair pull test
- Light microscopy
