Alopecia Areata

Alopecia areata is characterized by patchy scalp hair loss which occasionally affects every hair follicle on the scalp (alopecia totalis), or body (alopecia universalis).

The disease usually occurs between the the ages of adolescence and 30 years, but can appear at any age, affecting both sexes equally. Alopecia Areata has a rapid onset but tends to spontaneously reverse.

The cause of Alopecia Areata is unclear, however, genetic factors, auto-immune mechanisms, and the occurrence of stressful and/or emotional problems shortly before the hair loss are all thought to influence the condition.

Treatments for the disease include topical sensitizers, steroid shots, squaric acid dibutyl ester, diphencyprone, and hypnotherapy.
