I got this as a free sample, along with the shampoo and conditioner of the line. I liked the shampoo and conditioner, so I thought I would like the blow out treatment. I've spent a long time trying to erase the damage that my hair has gone through in the past several years, and I'm incredibly annoyed at how with one use of this product, it has completely damaged my hair all over again. I don't know how it damaged my hair so badly, but my hair feels like straw now. The product itself was very thick, sticky, and my brush could barely get through my hair, which is thin and generally really easy to brush. It took longer for my hair to blow dry, it gave it a weird, hard texture, and my hair looked dull. This product is such a disappoint and I would never pay money for it.

This product made my hair color look better and definitely gave me lots of body ! Love it...my hair is fine and this made a big difference...will use it all the time!

This treatment smells divine. It made my hair nice and smooth and look thick.

It smells wonderfull and it does the job, my hair looks bigger. Only thing that I dont like about it is that my hair is not smooth as it usually does..

This is the new serum that is supposed to make the hair plumper and fuller I believe. I purchased the serum, as I use colour saving shampoo so I didn't want to use the shampoo or the conditioner, I just tried the serum. I bought it at shoppers drug mart in Canada for $6.50, but you can probably get it cheaper in the states. This is what the website claims:
For Fuller, Thicker Hair. Plumps thinned-out ends for beautiful fullness
The first hair range with fibra-cylane™ and pomegranate extract that plumps wispy ends for a fuller look.

Proven to Perform
Instantly THE LOOK OF MORE HAIR*
Thinned-out ends look plump

I have been using it for about a month and I do notice a difference, however, I feel that the l'oreal fibrology hair line works much better, for me personally.
