Alopecia Areata Picture

Alopecia areata is the name for a condition in
which round patches of hair loss appear suddenly. The hair-growing tissue is attacked by
the patient's own immune cells for unknown reasons. There are three stages: first, there
is sudden hair loss, then the patches of hair loss enlarge, and last, new hair grows back.
This process takes months, sometimes more than a year, but rarely does the hair never grow
back.

The picture above shows the round patches of hair loss associated with
Alopecia Areata.
