Contact Immunotherapy for Hair Loss

Contact Immunotherapy for Hair Loss

Topic Overview

Alopecia areata is hair loss caused when the immune system attacks hair follicles , where hair growth begins. Contact immunotherapy may be the most effective treatment for severe alopecia areata. 1 A common medicine used is diphenylcyclopropenone (DPCP).

DPCP, a liquid, is "painted" on the scalp once a week. The concentration of the solution is increased at each treatment session until a mild allergic reaction occurs. Hair growth may appear within 3 months of beginning treatment.

Side effects of contact immunotherapy include a severe rash ( contact dermatitis ) and swollen lymph nodes , especially in the neck.
