My hair is also very fine and flyaway to.
The shampoo is described as being able to offer a mirror like shine to dull hair, and I can say this is true, my hair is dull and bring processed to blonde doesn't shine very well at all. But that being said my work mates have commented and said my hair does look more shiny recently win win.
Ingredient wise Camellia Oil and White Tea extract are present which help to moisture the hair from roof to tip without weighing down the hair. Now scent wise some people have described it as floral I personally don't I think it's more of a fresh clean scent, I love the smell and thats one of the things that made me buy it, I can smell it on my hair for hours after washing it, I love that as it makes me feel clean and that my hair is clean.
I bought the conditioner that matches the shampoo to but you know how it goes the shampoo always runs out first so I figured it would make more sense to get the large shampoo and normal sized conditioner as they will probably run out at the same time now haha.
I know Wella have a new range out now to called FUSION my beady eye is on that to, but let's see how long this takes me to use up. Another reason I love this is my opinion is that if you have a nice haircut and you colour your hair to, you need to look after that colour, so that's another reason in my justification in buying posh products.
It may help to know I picked up this huge size for £20 which is a bargain as it's normally £40 I can't remember the site but if you scour the net you should be able to find a good deal to.
