The National Institute of Arthritis and Musculoskeletal and Skin Diseases defines topical sensitizers and their various uses in treating alopecia like this:

  • Topical sensitizers–Topical sensitizers are medications that, when applied to the scalp, provoke an allergic reaction that leads to itching, scaling, and eventually hair growth. If the medication works, new hair growth is usually established in 3 to 12 months. Two topical sensitizers are used in alopecia areata: squaric acid dibutyl ester (SADBE) and diphenylcyclopropenone (DPCP). Their safety and consistency of formula are currently under review.
