Follicular Unit "Exploitation": Follicular Unit Extraction Followed by Laser Hair Reduction-A Novel Approach to Repigmentation of Postburn Leukodermic Scars.

Correction of depigmentation of postburn leukodermic scars is daunting. In contrast to vitiligo, the success rate of skin grafting techniques is much lower in postburn scars owing to altered skin architecture and poor graft uptake. Cellular transfer techniques such as noncultured epidermal or epidermal or keratinocyte suspension suffer the limitations of modest efficacy and high procedural cost. Follicular transplantation by the follicular unit extraction technique is being extensively used in vitiligo. Recently, it has been reported for the correction of scar alopecia. Although this approach is expected to significantly repigment pliant scars, the cosmetic unacceptability of the retained hairs may warrant removal. We describe an innovative three-step protocol to provide a repigmented smooth scar. We vernacularly labeled this technique follicular unit "exploitation," as the follicular units "exploited" positively for repigmentation were later removed by laser hair reduction.
