I received this shampoo as a gift & I can really see a difference after using. After a month my colour is still vibrant meaning I won’t have to have my hair coloured so often. It has no sulphates or harsh chemicals which is also great.
I go out in the sun & swim regularly so my colour seems to fade really fast. I tried different & expensive shampoos before, without seeing a difference but I have been using this for a few weeks & my colour is holding much better & no sulfates or rubbish go in my hair. Overall I am really impressed
