Use of nonablative laser for corrective hair transplantation.

One of the unfortunate legacies of hair transplantation from the 1960s into the 1990s is the large plugs that become cosmetically noticeable after patients have lost surrounding hair. To correct this appearance, physicians have used laser hair removal, linear excision of existing plugs, and punch biopsies with redistribution of the harvested hairs, but many patients are still left with unsightly textural changes, called cobblestoning. In this case report, we present a new treatment option for improving textural irregularities using a nonablative diode laser. To our knowledge, this has not been reported elsewhere in the literature.
