I have sensitive skin. I use it on my beard. This product works really well but you have to use it everyday. It works better in combination with the gray hiding products. If you combine them it works well however even if you miss even one day the color fads out a little. It work better on head hair then beard hair. The shampoo is very qiuck. It takes only few minutes. Best for sensitive skin. No allergies for me so far. I like the shampoo and conditioner more than the other gray hiding formulas I have used before because it is clean and qiuck
