    TLDR Platelet-rich plasma (PRP) is an effective treatment for lichen planopilaris.
    A single-blinded randomized clinical trial involving 24 patients with lichen planopilaris (LPP) compared the effects of platelet-rich plasma (PRP) injections combined with topical clobetasol versus topical clobetasol alone. Both treatments initially reduced the Lichen Planopilaris Activity Index (LPPAI), but after 6 months, the LPPAI significantly increased in the clobetasol-only group. The PRP group showed significantly lower LPPAI scores at 2 and 6 months and higher patient satisfaction at the end of the study. No serious adverse effects were reported, and PRP injections were well-tolerated. PRP is suggested as a new and effective treatment option for LPP.

      Scalp biopsies are crucial for diagnosing hair loss conditions like Diffuse Unpatterned Alopecia (DUPA) and retrograde hair loss, as treatments like finasteride and dutasteride may not be effective if other conditions are present. Combining PPAR-GAMMA agonists with retinoids could improve treatments for conditions like Lichen Planopilaris.

      Platelet-rich plasma (PRP) therapy for hair loss is expensive, painful, and often ineffective, with mixed reviews on its benefits. Alternatives like minoxidil, finasteride, and hair transplants are suggested as more reliable options.
