I was even surprised by the amazing results ! I have fine hair and after one use (combined with the conditioner), my hair was visibly with more volume. I recommend 

I only bought a travel-size of this shampoo and I’m so glad because it doesn’t suit my fine hair at all. It left my hair feeling heavy & weighed down and I washed my hair again (different shampoo) a day later as I couldn’t stand how my hair felt. The result definitely didn’t match the description.

My hair is really fine and no longer thick since the menopause. This shampoo gives it body and makes it easy to style

I saw this shampoo recommended by Lisa Armstrong on Instagram. I can honestly say that it is a game changer. And yes it is expensive but you only need to use a very small amount. My 21 year old daughter has “borrowed” it too on her long split ends and raved about it too.

This is NOT for fine hair. It is for coarse, unruly or wiry hair. They have other products for fine hair. My hair is very thick and prone to frizz and I always have to dry then straighten it to tame it. With this and the conditioner, it's almost like having a salon blow-dry. For the correct hair type, I think this is exceptional shampoo.
