Not good for fine hair

Soooo many silicones! Darn, I really wanted to like this. If you have fine hair like I do, this product will eventually dry it out (unless you do some serious, daily deep conditioning).

Not for my hair

I have bleached hair and heat style every other day, this product was not strong enough for me to protect. Might be better on normal hair.

It Smells so good!!

This smells like Hollister cologne <3 I fell in love with it just from the smell, but it did a nice job at keeping my hair from frizzing and left it shiny and stray free. I would purchase this, and might once I run out of the sample size, but it might not be in my budget. Great product!

Not for fine hair

The first time I used it on my fine long hair it seemed to add volume but it also dried it out

Did not notice much of a difference

The smell is great after you apply heat. I was hoping it would make my hair faster to dry but it seemed to make very little difference.

Blow dry lotion

I like this brand but since i have super-short hair and don't blowdry then doesn't really apply to me.

Decent

I don't really use hair products, but this is pretty good for the frizzies. I'm going to use it just so it's not wasted.

HAir was friizier than my regular protectant

Not sure what all the fuss is about. My hair was frizzier than normal after using this product. I have medium tick coarse hair with a slight wave. Hair was not smooth. It was like there was no product in my hair.
