Genetic reasons are a crucial factor stimulating hair loss.
Genetic predisposition is responsible not only for the appearance of hair loss but also for the rate of its progress during one’s lifetime.
If genetic predisposition exists, then hair loss is precipitated by the action of androgens and aging.
In short, thinning arises due to the organism’s insufficiency to produce the necessary amount of new, healthy hair.
