What is Androgenetic alopecia / male pattern baldness?

Androgenic Alopecia is a hair loss condition characterised by shrinkage (miniaturisation) of hair follicles which progressively gets worse until the follicles become obsolete. Androgenic alopecia may sometimes be referred to as Male pattern baldness (MPB) or female Pattern Baldness.

The pattern of hair loss in androgenic alopecia is progressive and varies between men and women. This is usually classified by the Norwood classification.

Androgenic alopecia is caused by Hormonal and genetic factors.

Androgen Hormones: Patients who suffer with Androgenic Alopecia will generally have increased sensitivity to androgens especially DHT (dihydrotestosterone). DHT, a derivative of testosterone can have an influence on hair cycles leading to shorter hair cycles and therefore hair follicles are shorter and thinner (usually referred to as miniaturisation).

Genetics: There is a general consensus with researchers who believe several genes play a role in androgenic alopecia. It is unclear if Androgenic alopecia is an inherited condition, as several genetic and environmental factors are involved. However, it does seem to cluster in families. Therefore, if you have close family relatives who suffer with Androgenic alopecia there is risk you may also suffer from it.
