- The dermal papilla which harbours the hair root has receptors for male hormones.
- An important biological feature of androgenetic alopecia is a change in the effect of the naturally occurring androgen or hormone, dihydrotestosterone(DHT).
- Normally, the enzyme 5 alpha-reductase converts testosterone to DHT in the hair follicle.
- Men and women genetically predisposed to pattern baldness often have higher levels of DHT in their scalp, and/or may be more sensitive to its effects.
- DHT acts on the hair follicle, causing it to undergo a shortened anagen or "growing" phase.
The hair shaft becomes progressively shorter, finer and lighter in appearance until it is virtually transparent and does not emerge from the follicle, a process known as "miniaturization."
