Androgenetic alopecia and microneedling: Every needling is not microneedling

Published:March 21, 2019DOI:https://doi.org/10.1016/j.jaad.2019.02.070
      To the Editor: We read with interest the deliberation by Rodrigues et al on use of platelet-rich plasma (PRP) to treat androgenetic alopecia (AGA) that was published in the Journal of the Academy of Dermatology.

      Treatment of male pattern alopecia with platelet-rich plasma: a double-blind controlled study with analysis of platelet number and growth factor levels.
      In this pilot study, 26 of 30 patients with AGA who had been screened for study inclusion were recruited and treated with 4 sessions of subcutaneous PRP injections biweekly. Rodrigues et al found a statistically significant increase in hair count, hair density, and percentage of anagen hairs in the PRP group at 12 weeks' follow-up. Rodrigues et al deserve acknowledgment for their sincere attempt to generate evidence by a placebo-controlled trial in this less-charted territory.
