is a localized condition in which hair is lost from the body. Often, it results in a few bald spots on the scalp, each about the size of a coin. The disease may be caused by psychological stress.
Alopecia areata is believed to be an autoimmune disease related with the immune system of the hair follicles. The underlying mechanism involves failure by the body to recognize its own cells, with subsequent immune-mediated destruction of the hair follicle.
Treatment ― OTC Drugs
Some people with mild alopecia areata recover within a year without treatment. However, most people experience recurrences at random sites on the scalp.
Intralesional steroid injections are the most effective treatment. Immunotherapy can be tried if large areas of the scalp are affected.

Alopecia areata, also known as spot baldness, is a condition in which hair is lost from some or all areas of the body. Often it results in a few bald spots on the scalp, each about the size of a coin. The disease may cause psychological stress. People are generally otherwise healthy. In a few cases, all the hair on the scalp is lost (alopecia totalis) or all body hair is lost (alopecia universalis) and loss can be permanent.
Alopecia areata is seen on the back of the scalp. In typical cases, it appears suddenly with a completely smooth surface and a size of 2-3 cm.
