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 found that this shampoo wasn't anything special, there was no distinct smell to enjoy, nor did it lather well or spread evenly in my hair. My hair was left brittle and looking unconditioned even after using a conditioner and leave in treatment. So wouldn't buy this again as it's not for my hair type.
