Real hair on the hairline extenuates the realism of SMP creating a super natural and real 3D hairline. SMP and FUE combination treatment undoubtedly achieves the most natural looking hairlines. Following hair transplant surgery some clients add SMP in-between the transplanted hair to compliment their hairline. The instruments used in hair transplant surgery leave small gaps between the transplanted grafts. SMP is a more precise technique that can effectively close the gaps between the grafts creating a natural hairline that look more fuller and not patchy.
