Hello,
From the biopsy report, the differentials for your hair loss are lichen planopilaris, follicular degeneration, traction alopecia which is common due to pulling of hair while forming a bun or plait, chemical abuse or trichotillomania (compulsive pulling or twisting of the hair which cause break off
and hence hair loss). Lichen planopilaris is a type of lichen planus
and affects hairy areas of the body, causing inflammation, hair loss, and scarring.
