Platelet-rich plasma as a novel treatment for lichen planopillaris

Treatment of lichen planopillaris (LPP) remains a significant challenge due to the irreversible damage inflicted on hair follicles combined with the low efficacy of existing treatments. We hypothesized that growth factors released by the use of platelet-rich plasma (PRP) may arrest the development of LPP. To test our hypothesis, we treated an LPP patient that has failed previous treatments with a new PRP regimen. Following PRP treatment and six months follow-up, the patient experienced complete regression of itching and hair shedding. To the best of our knowledge, this is the first report of successful treatment of LPP with a PRP regimen.
