Platinum Infusion Shampoo

I've always used Loreal Silver shampoo when my hair was blonde, but this time I was persuaded by the stylist to try the Hannon Platinum Infusion Shampoo and I must say it was the price that convinced me- R130 + it stated on the bottle that it is Salt- Free, always a plus point if you have a Brazilian Blowout!! I've tried it for more that a month and this is the absolutely worse product that I've used, not only does it do nothing to the yellow brassy tones, it also dried out my hair and gives me an itchy scalp! I've also noted on the ingredients list that there is Sulphate listed, so much then for being "Salt- Free"!!! Crappiest purple shampoo ever! I will not recommend it to anyone!
