Alopecia areata is a common disease that results in the loss of hair on the scalp and elsewhere on the body. There are three types of alopecia areata; alopecia areata, alopecia totalis totalis and alopecia areata universalis.

Alopecia areata totalis presents itself as total loss of hair on the scalp

In all forms of alopecia areata, the hair follicles remain alive and are ready to resume normal hair production whenever they receive the appropriate signal. In all cases, hair regrowth may occur even without treatment and even after many years.
