Fraxel Re:Store will not damage hair follicles
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.
