As with any treatment for alopecia areata, the success rate for DPCP/DCP depends on the person. Generally speaking, the chances for success with DPCP/DCP are 40-60%. Moreover, a study by Wiseman et al. (2001) found that around 78% of all patients obtained clinically significant regrowth after using DPCP/DCP for 32 months. The chance of relapse is also a common concern amongst patients. There is no way to determine one’s specific risk of losing the hair they regrew with DPCP/DCP. Wiseman et al. (2001) also found that roughly 63% of patients that experienced clinically significant regrowth relapsed by the 37 month follow up appointment. All this is to say, it is important to speak with your dermatologist about your specific situation.
