Successful Treatment of Pediatric Alopecia Areata of the Scalp Using Topical Bimatoprost

In a case study from 2016, a 9-year-old girl with multifocal alopecia areata (AA) of the scalp, which was resistant to standard corticosteroid treatments, experienced successful hair regrowth after being treated with topical bimatoprost. Initially, the patient was treated with intralesional triamcinolone acetonide and clobetasol solution, with minimal improvement. The addition of minoxidil solution also failed to elicit a significant response. However, when treatment was switched to bimatoprost 0.03% ophthalmic drops, applied twice daily to all patches, significant hair regrowth was observed after one month. After two months of bimatoprost treatment, there was significant regrowth, and after seven months, complete regrowth was achieved, leading to the discontinuation of bimatoprost. This case suggests that bimatoprost could be a viable treatment option for pediatric scalp AA, warranting further investigation through a pilot study.
