HAIR LOSS IN WOMEN
Even if people tend to think that hair loss among women is rare, %30 of all women experience thinning in their hair at least several times. Alopecia is the medical term for abnormal or intense hair loss. It has many different types and shows the same symptoms both in men and women. The genes, some diseases or pregnancy can cause alopecia among women.
Approximately %90 of the hair loss in women caused by androgenetic alopecia. This type of hair loss is called “male pattern hair loss” in men, and “women pattern hair loss” in women. It is defined differently because they look different on men and women. It starts from the temples in men and become more visible when it starts to affect hair line. But in women, it starts from the side and the top of the head. Therefore, it is harder to realize this kind of hair loss in women.
The reason of androgenetic alopecia is androgens, and it usually happens because of genetics. Since birth control pills, cysts, menopause and pregnancy changes the balance of the body, they may cause androgenetic alopecia, too. The levels of hair loss in women are exemplified below:
Hair loss in women increases with menopause, pregnancy, and after pregnancy. And it gains speed with external factors, medications, hormonal and seasonal changes. But hair loss proceeds very slow in women, and the thinning is not severe. With the diagnosis and correct treatment of the reason, the hair loss in women stops, and the
hair goes back to its normal state.
In this type of hair loss, aromatase enzyme and 5-Alfa reductase enzyme plays important roles. 5-Alfa reductase enzyme, which is the number one cause of the male pattern hair loss, is less present in women. Aromatase enzyme takes part in estrone and estradiol making, and it also reduces the amount of DHT.
