Abstract
The term cicatricial alopecia results from irreversible damage to epithelial stem cells located in the bulge region of the hair follicle with subsequent scarring. Based on the mechanism involved in follicular destruction, cicatricial alopecia is divided into primary and secondary forms. Primary cicatricial alopecia are divided into four groups according to their prominent inflammatory infiltrate: with lymphocytic, neutrophilic, mixed or nonspecific cell inflammation pattern.
The review presents the main clinical, histological and dermatoscopic signs of various types of primary cicatricial alopecia.
