Alopecia Areata

Alopecia areata, commonly known as spot baldness, is a disorder that causes hair loss in one or more places of the body. It frequently results in a few coin-sized bald patches on the scalp. Psychological stress and disease are potential causes of alopecia areata in at-risk individuals, although there is usually no visible trigger. People are typically in good health. In rare cases, all of the hair on the scalp (alopecia totalis) or all of the hair on the body (alopecia universalis) is lost, and the loss might be permanent. It differs from pattern hair loss, which is frequent in men.
