Efficacy of intradermal minoxidil 5% injections for treatment of patchy non-severe alopecia areata.

Background: Intradermal minoxidil is used as an off-label treatment for patchy non-severe alopecia areata (AA) either alone or in combination with steroids; however, studies estimating its efficacy are still lacking.

Objectives: To assess the efficacy of intradermal delivery of minoxidil 5% alone and in combination with intralesional triamcinolone acetonide for treatment of patchy non-severe AA.

Patients And Methods: One hundred patches in twenty patients with patchy non-severe AA, five patches for each patient, were included in this prospective intra-patient comparative controlled clinical study.
