Hi All, can anyone help! I have a client with 80% grey. I’ve foiled her hair with Wella 66/46 using 6% the colour is coming off on her towels, there isn’t much fading, anyway I did it again and she’s saying it’s happened again. I advised to use a colour shampoo and conditioner, less sulpha and synthetics in etc, but still happening! It maybe her grey is resistant but she’s now demanding money back, in 12 years I’ve not come across this. I’ve emailed Wella so wait to hear. Any advice?!
