I was sent this serum to try and I am very impressed with the results. Like Charlene I was surprised that it was designed to be applied to soaking wet hair straight after rinsing off conditioner, but it really works! I have VERY frizzy hair, and lots of it, so when I apply any serum to towel dried hair I find I have to use a lot of it in order to work it through my hair. This usually results in product overload and a horrible "coated" feeling when I straighten my hair. By applying this to wet hair as instructed I could use much less but still get it all the way through my hair. (The packaging said 1 pump but I used 2 as I have long hair).
I found that when I used this and then left my hair to dry naturally it was still fairly frizzy, but better than normal. It also felt much softer.
Where I found this product brilliant was when I used it before straightening my hair. It was so much quicker to blow dry, and much, much easier to straighten. It felt incredibly soft and best of all : No frizzies! It also stayed straight for longer.
I have not tried using this with my hair curly yet, but I think I will give that a try next and see how it goes.
I will definitely replace this product for myself when it finishes.

I often use hair serums after styling to tame frizzies and get my curls looking a bit more sculpted. I have to be careful not to use too much or it can weigh my hair down. I was surprised to read on the packaging of this product, that you have to use it on wet hair, straight after conditioning. Note that I usually use an extra leave-in conditioner and mousse after washing and conditioning my hair. I will only then use a serum if needed. But I decided to give it a go and use it before my other styling products. Now I ask you, why did someone not tell me this before?? It works like a charm. I don't know if this tip was intended for someone like me who uses so many styling products, but it works. My curls turn out beautifully defined and not nearly as frizzy as before. I also really like the product itself. Many serums can feel sticky or 'greasy'. I have another one in my cupboard that I actually struggle to get off my hands when applying it to my hair. This one feels beautiful and leaves almost no deposit on my hands. I like that. I am very happy with this product and I will purchase it for myself!
