    TLDR Hair transplantation may work for some types of scarring alopecia, but results vary and more research is needed.
    In 2018, a systematic review analyzed the effectiveness of hair transplantation for treating primary scarring alopecia, involving 34 patients across 15 reports. The procedure yielded moderate to positive results in 26 patients, while 8 experienced negative outcomes or disease recurrence. Hair transplantation was found to be potentially effective for central centrifugal cicatricial alopecia, en coup de sabre, discoid lupus erythematosus, pseudopelade de brocq, and folliculitis decalvans, but results were mixed for lichen planopilaris and frontal fibrosing alopecia. The review suggested cautious interpretation of the data due to possible publication bias and highlighted the need for controlled disease before surgery, standardized measurement protocols, and more robust scientific studies to establish concrete recommendations for hair transplantation in scarring alopecia.
