Cicatricial alopecia is a loss of hair associated with scarring and destruction of hair follicles.


Conditions that can result in cicatricial alopecia:

(1) trauma

(2) chemical, radiation or thermal burns

(3) systemic lupus erythematosus

(4) lichen planopilaris (associated with lichen planus)


Clinical features:

(1) area of alopecia determined by distribution of the underlying cause

(2) dense consistency to the skin due to associated fibrosis

(3) no regrowth of hair


A skin biopsy in the affected area shows:

(1) loss of hair follicles
