I bought this prodict havinbg nig hopes on it. I have black hair, so when I applied it on it, and despite being specific for rich darks, the color difference was too noticeable. Corn starch is a better dry shampoo than this one. Really disappointed as I have always liked Vidal Sasson products, but not this time. After applying it, the oily hair remained the same. I have tried otger dry shampoos and this one is far to be not even the best, but a good dry shampoo.
