Lichen planopilaris scarring alopecia Low-Level Light Therapy LLLT inflammation hair regrowth LPP light therapy

TLDR Low-Level Light Therapy significantly reduced inflammation and promoted hair regrowth in patients with Lichen planopilaris.

In 2020, a study was conducted on four female patients, aged between 28 and 65, suffering from Lichen planopilaris (LPP), a type of scarring alopecia. Despite previous systemic treatment, their LPP remained active. The study found that Low-Level Light Therapy (LLLT) significantly reduced inflammation, eliminated symptoms, and promoted hair regrowth without side effects. The LLLT treatment duration varied from 6 to 18 months, with daily use of the device. All patients showed improvement after 3 months. However, the study concluded that larger controlled studies are needed to fully understand the benefits of LLLT on LPP treatment.
