Androgenetic alopecia is the number one cause of hair loss in men and women. Affects 50% of men over 50 and 30% of women post-menopause.
How It Happens:
- DHT hormone attacks genetically sensitive hair follicles.
- Follicle gradually shrinks — hair becomes thinner and shorter.
- Result: transparent vellus hair instead of thick hair.
Male Pattern:
- Hairline receding from forehead and temples (M shape).
- Thinning at crown.
- May progress to complete baldness.
Female Pattern:
- Diffuse thinning at crown while maintaining front hairline.
- Rarely reaches complete baldness.
Treatment Options:
- Minoxidil: Topical solution — stimulates hair growth. For men and women.
- Finasteride: Tablets — block testosterone to DHT conversion. Men only.
- PRP: Platelet-rich plasma injections — stimulate follicles.
- Hair transplant: Definitive solution for advanced cases.
Treatment slows or stops loss but early start is better — dead follicles don't return.
