What is scarring alopecia?
Scarring alopecia refers to a group of hair loss disorders where inflammation destroys the hair follicles and replaces them with scar tissue.
It often presents with redness, scaling, and discomfort, and once the follicle is scarred, hair loss is usually permanent.
Red light therapy may offer anti-inflammatory benefits in early or pre-scarring stages, but it cannot reverse scarring once follicular structures are lost.
