Alopecia Areata is a skin disorder that causes hair loss usually in patches, most often on the scalp. These bald patches appear unexpectedly and affect only a finite area. Within 12 months or less, the hair grows back. However, for some people the problem can last longer and be more severe, causing total baldness (alopecia totalis) or total loss of body hair (alopecia universalis). About 62% of the people experience the first episode of hair loss before the age of 21. It is usually followed by hair regrowth. However, it is common for the problem to come back. New bald patches can develop at the same time when older ones are re-growing hair.
In most small patches of alopecia areata, the hair regrows within 6 – 12 months. However, it is common for the problem to happen again.
