I tried one of the new kits (L'Oreal, I think) that claims to dye your hair and give 100% grey coverage in just 10 minutes at the weekend. It left my hair in nice condition, but the colour wasn't very strong, and it was hopeless at covering the grey - so I was disappointed with the results. I'll be reverting to my old 30 min kits , I think ...
Has anyone else tried the new kits? Did they work for you?
