^^I actually really like it a lot!
The only hard thing is that I had my hair darkened to about a Jennifer Aniston brown/blondish color (it used to be super blonde) the day I bought the Kerastase spray, so my hair looks shinier, but I am not sure if it is just the darker color or the product.
I am loving the vitamins. I have noticed a lot less hairs in my widetooth comb after showering. Again, not sure if it is the vitamins, the night spray, or what.
