MATERIALS AND METHODS The study was conducted in a private hair transplant clinic after obtaining informed consent. Only those patients were included who had a previous strip harvest surgery (FUT) and opted for Follicular Unit Excision/Extraction (FUE) procedure. In all the patients, the donor hairs were trimmed to about 1-2 mm length. The width of the scar, the hair density above and below the scar, and hair angles above and below the scar were measured. All the patients underwent FUE procedure using 0.9 mm serrated punch. Twenty attempts were made above and below the scar (about 0.5 cm), and the total number of hair and transections was measured. All the data were analyzed statistically. RESULTS Ten patients were included. The average width of the scar was 2.47 mm. The mean hair density was found to be 155.4 hairs per cm2 above the scar and 130.8 per cm2 below the scar. The mean hair angle was found to be 28.21 degrees above the scar and 39.19 degrees below the scar in midline occipital above the scar (P less then .05). The average hair count was found to be 49.8 hairs above the scar and 47.2 hairs above the scar (P less then .05). The transection of hair was doubled below the scar (P less then .05) CONCLUSION The Follicular Unit Transplantation (FUT) procedure does leave some impacts on the donor area other than the scar only. The change in angle results in higher transection of hair above the scar. © 2020 Wiley Periodicals, Inc.BACKGROUND Hair transplant procedure is a surgical procedure which affects the sensitivity of the scalp. OBJECTIVES To compare scalp two-point discrimination (2PD) values in healthy controls and patients who had hair transplant surgery. PATIENTS/METHODS The comparative study was conducted in 25 healthy individuals and 25 patient who underwent hair transplant surgery (either strip surgery or
