Will Fraxel Restore Damage Hair Follicles at Level 9 and 75 Mj Setting?

Question

Scar on the back of the head

Steven F. Weiner, MD · Answer

Hair follicles are damaged by a laser that is attracted to melanin, the pigment in skin and hair. The typical wavelengths of the hair removal lasers are lower (Diode - 800, Alexandrite 765) than the Fraxel Dual (1550 and 1927nm). The Fraxel might singe the hair but won't permanently affect the growth of the hair.

Richard Fitzpatrick, MD (in memoriam) · Answer

The Fraxel lasers are all targeting water , so have no selectivity for hair follicles. The Re:Store heats in very small columns , which are not large enough or high enough energy to kill hair follicles. Since it is a scar that is being treated, the treatment can usually be confined to the scar tissue and eliminate any possibility of damage to hair . That generally is not necessary though. I have treated a number of scars on the scalp using Fraxel Re:Store without ever damaging hair follicles.
