Background: There have been numerous methods to treat androgenetic alopecia but few methods to treat it effectively and permanently. Objective : The purpose of this study was to evaluate bundle hair grafting as an effective treatment for patients with androgenetic alopecia. Methods : Bundle hair grafiing was performed on 52 patients with androgenetic alopecia who had visited the department of dermatology, Kyungpook National University Hospital and Fatima Hospital. Questionaires regarding cosmetic satisfaction, side effects and general efficacy were recorded by patients themselves one year after hair grafting. Results : The results are as follows : 1. The loss of transplanted hair was most common during the third week(48.1%) after hair grafting. 2. The regrowth of the hair on the recipient site was most common during the 4th month(59.6 %) after the hair graft. 3. Bundle grafting afforded excellent cosmetic satisfaction even after one session in the alopecic area, 4. Facial edema, temporary sensory loss on the donor site, folliculitis and small pitted scarring were seen 19.2%, 5.8%, 1.9% and 3.8% of patients, respectively. 5. The disadvantages were the time necessary to carry out the procedure and the need for an experienced operator and assistants. Conclusion : We concluded that bundle hair grafting was an effective and safe therapeutic method for patients with androgenetic alopecia. (Korean J Dermatol 1997;35(5): 893-901)
