**5. Conclusions**

Cicatricial alopecia forms a group of disorders that destroys hair follicles and replaced them by fibrous tissue. Treatment of cicatricial alopecia is challenging because of permanent hair loss. However, in primary scarring alopecia, early diagnosis and treatment can limit or even prevent the progression of hair loss. In contrast to classical techniques including scar excision, local flaps, and tissue expansion, follicular unit hair transplantation offers an innovative and effective treatment option for stable primary scarring alopecia and mature secondary scarring alopecia with several advantages; safe, minimally invasive and aesthetically pleasing results, even after a single session.
