Laser Hair Transplantation

The document from July 1997 examines the use of CO₂ lasers in hair transplantation, noting both potential benefits such as decreased bleeding, reduced surgical time, and less traumatic graft handling, and drawbacks like higher costs and a slight delay in hair growth. It references studies, including one with 10 patients, indicating that laser-prepared sites might be as effective as or better than traditional methods. The author advises that laser hair transplantation be limited to small grafts and a maximum of 500 micrografts to ensure graft survival. Safety concerns are highlighted, with recommendations for protective measures to prevent damage and fire risks. Despite initial rapid adoption driven by market forces, the FDA's approval of a CO₂ laser system in November 1996 is seen as progress. The document calls for more training and studies to improve safety and efficacy in laser hair transplantation.
