Since Wella Koleston changed to the new ME formula I am having terrible trouble with skin staining on clients and can’t shift it with the usual emulsifying and stain remover. Anyone else having this trouble and any recommendations on which product to use to get it off? Luckily no one has complained and it must be coming off the day after once the skins natural oils get working but I hate sending clients out with a nasty stain And am bound to get someone who is going out after and wants it removing
