I have fine coloured hair and have tried many different brands to find one that suits. Some brands of volumising shampoo work fine at first but with repeated use can seem to cause build up on the hair and even aggravate my scalp. I've been using this shampoo for several months now and have had no problems. My hair is clean, full and without any static or product overload. I'm very happy with it so give it 5 stars. The only slight gripe I have is that the bottle does not look as great as some of it's competitors so I don't keep it on display, the cap has also snapped off on a couple of occasions.
