I've bought and rebought this many times, it's almost on an equal par with the Fudge shampoo, you just get a bit less for your money! It was recommended to me by my hairdresser and it really does counteract the brassiness/yellowness you get when you bleach your hair. It doesn't make your hair as purple as the Fudge shampoo, it makes it more silver so if that's the effective you're trying to achieve then this one's for you.
