It was long believed androgenetic alopecia and related to an overproduction of testosterone. For this reason is attributed to a virility bald above average.
We now know that is false: there is an above-average production of testosterone but rather an increased sensitivity of hair follicles to male hormones.
This condition is thus not a hormonal disorder but an abnormal function in the skin of the scalp.
Androgenetic alopecia is the most common form of alopecia, affects men but also women.
It consists of a progressive decline in the quality and quantity of hair is hereditary and hormonal.
ANDRO: hair loss comes from an abnormal reaction of the hair to androgens (male hormones that are also present in females).
GENETICS: This abnormal reaction is linked to a genetic predisposition. The androgenic alopecia is excessive sensitivity of the hair follicles to male hormones due to an inherited factor, both for women as for men. It is not a hormonal problem but from irregularities in the skin of the scalp.
