There are many lines of therapy, but no standard line for all cases. Consequently, treating severe forms of AA is challenging.<\/jats:p><\/jats:sec><jats:sec><jats:title>Objective<\/jats:title><jats:p>This study aimed to compare the efficacy and safety of the combination of diphenylcyclopropenone (DPCP) and platelet\u2010rich plasma (PRP) with DPCP alone in treating patients with severe or refractory AA.<\/jats:p><\/jats:sec><jats:sec><jats:title>Patients and methods<\/jats:title><jats:p>Our randomized clinical trial was conducted on patients with severe and recalcitrant AA. Group A included 13 patients who received only DPCP, while Group B included 11 patients who received both DPCP and PRP. After sensitization in both groups of patients, DPCP was applied to half the scalp weekly. In addition, PRP injection in all scalp was performed once a month in group B. The patients in both groups completed the study for six months.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The regrowth scale results were 53.85% and 54.5% for groups A and B, respectively.
