I have bought this shampoo and conditioner two times. The first time I used it, I actually got dandruff - which I had never had before. My scalp also felt oily after just a day, so had to rewash hair more frequently than normal. And the re-washing gave me more dandruff!!!
A month or so ago I gave it another go when it was on special. The same thing happened. So the left overs have been relegated to washing my two dogs. They seem to be fine with it :)
I bought the sample size of this product to try and I am glad I did. Wouldn't bother with swtiching to this product as it is nothing special. Lather, rinse and repeat - it could be any supermarket shampoo you are using. left my hair clean and soft, but also slightly dull and fluffy. I have thick fine straight hair which usually sits nicely but is inclined to get staticky and frizzy. Clear conditioner certainly didn't address this problem.
