Types of baldness

Androgenic alopecia is caused by the presence of the male hormone testosterone in the blood, which affects the health of the hair follicles. In the cells of hair follicles was discovered enzyme, which in interaction with testosterone produces other substance – more active hormone dihydrotestosterone. It adversely affects the hair follicles: in the parietal and frontal parts of the head, they become smaller and thinner, respectively changes the hair. It is also becoming thinner and lighter, the so-called vellus hair. It is noteworthy that the follicles at the hindhead do not have receptors sensitive to testosterone, and this area of the hair is the same.
By the age of 70 years old 80% men are bald.
This type of baldness can also occur in women with high levels of testosterone in their blood. Simultaneously, as a rule, their level of estrogens have been reduced. For such women it is characteristic of hirsutism and problems with the female reproductive system.
Alopecia areata is different by androgen. It starts with one or more bare spots in various parts of the head and other body parts, where the hair is growing. To determine the cause of this type of alopecia, it is necessary to see a specialist. It is important to remember that the disease is not passed itself. It can only worsen over time.
