Less commonly it can be more diffuse. Women with Alopecia Areata can have hair loss in other areas besides the scalp, including eyelashes and eyebrows. While considered a rare type of hair loss, Alopecia Areata still affects almost 7 million people in the US.
While we often speak of Alopecia Areata in general terms, there are actually a few different types of it. The most well-known is Alopecia Areata, which presents as coin-shaped lesions on the scalp, although the loss can occur in other areas of the body. Alopecia Totalis presents as total loss of the hair on the scalp. Alopecia Universalis presents as total loss of hair on the scalp, face, and body. Less common forms of Alopecia Areata are Diffuse Alopecia Areata, which is very sudden loss and thinning across the entire scalp, and Ophiasis Alopecia, which has a unique pattern of loss on the sides and lower back of the scalp.
