hey babe, i'm a hair dresser, and i say its fine. The comment above is correct though, the colour may not come out as you want it but thats usually if your going lighter, and this doesn't happen to everyone. It also Can depend on what shampoo you use. If your able to ask the hairdresser to do a skin test, this will make sure your not too sensitive for the colour, as sometimes your scalp can also change! I got my hair coloured the other week though and it was fine. Hope that helped xox
