Alopecia Areata is the most common type of Alopecia. Alopecia is an autoimmune disease in which the immune system attacks the hair follicles. In alopecia areata, the hair falls out in small, round patches about the size of a quarter. In some cases, people will only have a few bare patches, but in others, hair loss can progress to include the entire scalp (alopecia areata totalis) or the entire scalp, face and body (alopecia areata univeralis). Vita’s Hair Studio in Greenbelt, Maryland offers many natural hair enhancement solutions for all forms of Alopecia.
