In cicatricial alopecia the hair loss is permanent. The disease is exclusively located on the scalp, in 50% of cases there are no lesions of the disease in the rest of the body. The disease mainly affects the top of the scalp and other areas. It is due to the destruction of the hair follicle and its replacement with scar tissue, leading to permanent hair loss.
In cicatricial alopecia, the inflammation that destroys the follicles is located under the skin and the scar is not visible.
Affected skin is usually red, flaky, hyperpigmented or hypochromic.
