Effectiveness Of Low-Level Laser Therapy In Lichen Planopilaris
Researchers treated patients to low level light therapy (LLLT) using red light with a 630 nm wavelength.
All treated patients had lichen planopilaris.
Symptoms included redness (erythema), corkscrew hairs indicating too much keratin production (perifollicular hyperkeratosis), and hair loss.
After 3 and 6 months, the patients had more and thicker hair.
After 3 months, the erythema and perifollicular hyperkeratosis settled down, but after 6 months it had returned.
