This definitely is a very nice product, but unfortunately not suitable for my hair type. As I already have very thick and sometimes frizzy hair, this product just added more volume. Good news is, this means it is obviously doing exactly what it needs to do! I gave my extra samples to friends who specifically struggle with fine, flat hair and they were very happy with the results although some of them said that the shampoo doesn't lather as much as other shampoos. I also love the sleek looking packaging.
