I found this at a new hairdresser I visited who raved about how good this was on her other clients who had similar wavy hair to me, I do put all my trust into hairdressers which is not wise I guess but I don't really know hair that well. So I purchased this along with the conditioner.
It was expensive for the size, but did have a lovely fresh fragrance and did a pretty good job, but my hair was nothing amazing that a supermarket brand shampoo hasn't performed as well so for me this is just over hyped and over priced, have not had the urge to repurchase.
As with the conditioner, I like it, just wouldn't say it's the best product ever. My hair isn't worse when using it, it is a little better I think. I love the small, price and it's not too heavy in my hair. I don't find that I have to do a double wash either, it foams up ok on the first wash (usually an indicator that you don't need a second wash). I'll definitely buy it again, unless someone can tell me of something better.
