Comparative study between follicular unit transplantation with intact and non-intact hair bulb in treatment for stable vitiligo.

[OBJECTIVE] To compare the cosmetic efficacy of the transplantation of follicles with intact and non-intact hair bulbs in the treatment for vitiligo.

[METHODS] The single-hair follicle units with intact hair bulbs and un-intact hair bulbs were transplanted into the skin of vitiligo. The diameters of regrowing hair shafts and repigmentation of implanted follicles were detected analyzed by dermatoscopy (Beining BN-PFMF Skin and Hair Visualizer).

[RESULTS] The survival rates of follicles with intact and non-intact hair bulbs were 60.00% and 50.62%, respectively. The average diameters of hair shafts and repigmentation of the two groups were 92.83 ± 7.26 µm vs 55.86 ± 2.64 µm ( < .05), 2.62 ± 0.13 mm vs 2.63 ± 0.17 mm ( > .05), respectively.

[CONCLUSION] Single follicle transplantation was an alternative effective choice for the treatment of vitiligo. The skin implanted with follicle with non-intact hair bulb was less hairy.
