Hormonal Hair Loss - Androgenetic Alopecia (AA)
The scientific community has identified eight genes responsible for causing Androgenetic Alopecia (AA), a hormonal hair loss condition in both men and women.
Androgenetic Alopecia is a progressive and symmetric loss of scalp hair which is the result of a genetic predisposition of hair follicles to the hormone Di-Hydrotestosterone, (DHT). Put simply, hair loss in both men and women is genetic and we all inherit this hair loss condition from one or both of our parents.
Androgenetic Alopecia causes 95% of all hair loss in men and women.
How DHT Affects Hair Loss In Men and Women
DHT or Di-Hydrotestosterone is the primary cause of hair loss in men and women. DHT is a derivative of testosterone and is transformed into it's present state by an enzyme called 5-alpha reductase. This enzyme aids in creating DHT by attaching itself to the testosterone molecules which are then transformed into DHT.
DHT aids in male and female hair loss by attacking the hair follicles during their re-growth phase.
On average, men and women grow 100 new hairs per day while also losing 100 hairs per day. So, the hair loss problem is not an issue of losing hair; it is a problem of growing hair which is directly related to DHT and genetic predisposition.
Hair loss in men and women doesn't happen overnight. Hair loss occurs over the course of time. Due to the lasting effects of DHT, hair that is re-grown becomes finer and thinner over time, a condition also known as hair miniaturization. Eventually the hair stops growing and permanent hair loss results.
