4. Laser Hair Transplantation :: Posted Thursday, May 24, 2001 by admin ::
Lasers are used create micro-incisions in the scalp for the insertion of hair. There is less bleeding from the recipient sites and the laser forms scalp holes of a very consistent size and depth. The main disadvantage of laser is the skin trauma produced by thermal effects at the recipient site.
Lasers were first used for hair transplantation in 1992. Early results were variable due to thermal injury of the skin. However, newer pulsating lasers let the laser's light beam be rapidly pulsed up to hundreds of times per second. This pulsating avoids excessive heat build up of heat and preserves surrounding tissues. With the pulsing laser, hair insertion holes in the scalp from 0.3 mm to 0.8 mm are created. Then a small metal probe is used to further open the insertion point so that the blood vessels and the inserted hair follicle can interact.
Hair follicle grafts are prepared with a dissecting microscope and inserted into the laser-made holes.
