male pattern baldness varies in some situations, it is only in a number of spots. In other folks, the hair reduction can be increased. Occasionally it can involve the total scalp (alopecia totalis) or even all the human body and scalp (alopecia universalis). It is not achievable to predict how a great deal hair will be lost. Regrowth of hair in typical alopecia areata is normal more than a period of time of months or, occasionally, years, but are not able to be guaranteed.

In alopecia totalis and alopecia universalis the likelihood of complete regrowth is significantly less.
