Causes of hair loss
Depending on the causes that cause and the manner in which occurs in three distinct types:
1. Androgenetic alopecia: This is the most common type of hair loss in men and women and depends three factors, including age, genetic predisposition and levels of the hormone testosterone in the body. Although this hormone is considered a "masculine", small amounts of testosterone secreted in women, affecting among others the life cycle of hair. Studies in the past decades have shown that the most important element for aggravating androgenetic alopecia is the presence of the enzyme 5a reductase in the hair follicle. This enzyme converts testosterone that is normally at the same levels as in the bald and having hair to dihydrotestosterone, a much stronger hormone that acts locally in the hair follicle and eventually leads to the loss. The amount of enzyme in the hair follicle and its distribution on the scalp regulates generally the age at onset of hair loss, the hair loss rate and extent of final status.
The presence of this enzyme is regulated gene and is inherited from both parents. The result is the hair on the head to fall more quickly than normal, the new to come out every time more subtle and ultimately gives little or no fluff wool.
This disorder affects selectively the temples and the crown of the head, where existing hairs are getting thinner, until they finally disappear. In women, androgenetic alopecia usually occurs after the age of 40 and becomes more pronounced with the onset of menopause.

Occurs in men and women and is more rare form of androgenic alopecia. However it can be treated by administering the appropriate medication. For the appearance of alopecia areata implicated several factors, among which are hereditary predisposition, hormonal disorders, thyroid gland disorders, anxiety, depression, and especially the lack of iron in the body.
