Where is the hair loss located?
Any hair-bearing area of the body may be affected, with the extent of hair loss ranging from patchy spots on the scalp to a loss of all the hair on the scalp (alopecia totalis) to a loss of all the hair on the entire body (alopecia universalis). About 1 to 2 percent of those affected develop the latter two extensive forms. Alopecia areata can occur in combination with other forms of hair loss, including androgenetic alopecia (female pattern baldness).
