I've never left a negative review but this is an expensive product and I wanted to share my experience. Beautiful packaging but that unfortunately is the end of my positive review. The consistency of the shampoo is very thin, it smelt like washing up liquid and after using this and the matching conditioner my hair felt like straw and I struggled to get a comb through it when it was wet. Once dried and straightened it was just a mess I had to use serums to moisturise. Very disappointed, I won't use again never mind buy again. (My hair is blonde with some bleached highlights and is naturally slightly curly)
