I have "elder" hair - thin and fragile. Moreover, I color it regularly with e-salon which has been great at creating a red/copper color that looks great.
I have a drawer filled with root covers, powder fillers, conditioners. serums and more. When I saw the ad for this hair serum, I said, why not? what's another serum in my drawer- but really, this stuff works. My hair is glossy, has new body and actually does look thicker. Product is a win!
