The ones i try these days just don't cover my grey roots enough and i can't afford to get them done at the hairdresser. I have dark brown hair, and up until 2 yrs ago got away with semi perm. I am new to permanents, but none of them seem to coat it.
the best i have found so far is boots own, but it's not 100%. Movida is rubbish. my hair is very white. what do you use?
