One of the most sudden causes of hair loss that can occur within women and men and cause round patches of hair to literally disappear from the scalp is referred to as alopecia. Although the hair will often grow back after a period of time, most likely months after the initial spot has occurred within the head, it can be a difficult diagnosis to accept and cause many problems within the appearance and self esteem.
Although the causes of Alopecia are unknown and can be a variety of factors, there are three common causes which are thought to cause these round bald spots to appear within the scalp. The first is genetic and appears through family members, but it is important to remember that this is not contagious. The second could be from a disorder within the immune system which causes the body to attack the hair follicles which are growing through the tissue and the third could be caused by some factor which exists within the person’s environment.
There are many treatments that are used for the treatment of Alopecia, from topical treatments that are applied directly to the scalp to more invasive surgical treatments which use injections into the scalp to stop the hair loss and restart the hair growing cycle.
