Alopecia Areata

In this condition, hair is lost in round patches due to the immune system attacking hair follicles. Alopecia areata can result in the loss of hair on the scalp and elsewhere on the body. It rarely causes total body hair loss. Nails may also be affected, and may be an early signal of the disease, with tiny pinpoint dents, white spots or lines, roughness, loss of shine or thinness.

Alopecia areata can appear at any age, even childhood. Like many other autoimmune diseases, someone’s genetics, in addition to other factors, can trigger the condition.
