Abstract
A hair transplant procedure is described which includes preparing a plurality of hair plugs from a donor site on the scalp. A corresponding number of incisions are drilled into the hairless recipient site using a pulsed laser beam. Preferably, the beam is generated from a high power, RF excited, carbon dioxide, slab waveguide laser. The pulse characteristics of the laser are chosen to ablate the tissue to the desired depth while minimizing bleeding. The plugs are inserted into the incision and hair growth in the recipient region is promoted.
