I have very fine, naturally wavy mid length hair and for years (no decades!) have struggled to find a shampoo that truly gives my hair body and volume. This product is it!!! It does exactly what it says on the bottle. I even used to have to wash my hair daily, but find I can manage to do it every other day. Even after a night's sleep my hair still has volume, has stayed in it's style and is not greasy. Brilliant! I only wish I had found this product years ago. I also use his conditioner too, but only a really tiny amount, the combination of the two definately suit my hair.
