Aren’t laser hair transplants better?

No. Investigated over a decade ago as a technology which might have utility in hair transplantation, lasers were found to have a number of limitations that rendered them undesirable as a technology for surgical hair restoration. Chief amongst these is the laser’s use of high energy light and heat energy to thermally ablate [ burn ] an opening in the skin. Despite being a focused beam of light, collateral heat injury is created within the surrounding tissue that is detrimental to graft survival. The use of very small grafts in today’s transplantation procedures necessitates an optimal receptor zone field to ensure graft survival. Control of the transplanted hair’s angle of growth is an additional key aspect of a high quality hair transplant and varies literally from site to site in some regions. The degree of control required to effect these changes is best obtained by a practiced human hand manipulating a miniature machined steel blade.
