What have you done to it ?

I have used this on my coloured hair for 15 years. My hair is very long and the colour care shampoo and conditioner always left it smooth, soft and silky. I go to festivals a lot and even after 4 days it still looked brilliant. Now I have tangled, frizzy, flyaway dry hair even when it is freshly washed. Thanks, this product was excellent now I have to find something to restore my hair back to health. I will never buy this again it is a danger to my hair!!!
