Alopecia totalis; Alopecia universalis
Most of the time there are no other symptoms besides hair loss, but some people may feel a burning sensation or itching.
Alopecia areata usually begins as one to two patches of hair loss, most often on the scalp. It may also be seen in the beard, eyebrows, and arms or legs.
Roundish patches of hair loss are smooth, and may be peach-colored. Hairs that look like exclamation points are sometimes seen at the edges of a bald patch.
On occasion, a scalp biopsy may be performed. Several blood tests may be done, because alopecia areata may occur with autoimmune conditions.
