This shampoo is lovely, it foams up well and leaves my hair the most manageable and shiny it has ever been. I have long, thick, curly hair and a lot of shampoos seem to contain silicone which sticks my strands of hair together and dries them out so it is impossible to manage and just gets all matted and snaps as I try to get all of the knots out. Having used this shampoo for a number of months now, I do not suffer with knots at all, there isn't even an ounce of frizz to my hair anymore and it is so healthy that my hairdresser thinks that I have stolen somebody else's hair Perhaps the most important thing about this shampoo to me is that I used to suffer with the most intolerable itchy and dry scalp. Further research suggested that it could be SLS that was causing my itchy scalp which is how I discovered this shampoo, as Yes To is SLS-free. Other SLS-free shampoos that I have tried do not foam up so my hair never felt clean, but this one foams up perfectly and as for my scalp, as I said, I "used" to suffer with an itchy scalp - not anymore! YAY!!!!!!!! This is my favourite shampoo and I cannot recommend it highly enough, especially for those who suffer with itchy and dry scalps!
