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. A common medicine used is diphenylcyclopropenone (DPCP). 1
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.
