Loss of hair in men and women is also considered to be caused by excessive oil in the scalp. This oil, that is also called sebum, clogs the pores of the scalp and stifles follicle growth. In time the hair root is asphyxiated, making it impossible for new hair to grow. If the scalp is not cleaned properly sebum becomes wax that clogs the pores. Thus, the new hair cannot come out. Permanent hairloss often has a lot to do with hormonal imbalances. Elevated levels of Dihydrotestosterone, or DHT, can cause hairloss. DHT is a male hormone that is also found in women in smaller amounts. Because hair follicles are ultra-sensitive to DHT, an excess of the hormone often causes the hair to fall out. Hairloss that is caused by DHT will need to be treated using one of several options.
