Heat protection best one
[This review was collected as part of a promotion.] I loved how it left my hair super soft shiny and manageable it has a smell uff that I loved it does not allow my hair to curl I feel that it lasts longer when I apply it before drying it does not leave residue on the scalp when you apply it it dries at once it does not leave your hair wet I recommend it to take care of the hair from the heat...

Smells toxic!!
If I cooks five zero stars, I would. This product smells horrible and full of chlorofluorocarbons. And it doesn't even work all that well.

Has potential.
[This review was collected as part of a promotion.] I wanted to love this spray more than I did. The frizz control is noticeable and my hair looked shinier which I appreciated. However it left my hair feeling a little dry and not as soft and manageable as I normally like, and I did not feel much heat protection during flat ironing which was disappointing. One important tip, less is definitely more with this one because too much product leaves the hair feeling sticky and heavy. The scent is really lovely though, one of my favorite things about it. As for value, since a little goes a long way the bottle actually lasts a good amount of time which makes the price feel more justified. A good product with room to improve but the shine and frizz control are genuinely there.

Just okay
[This review was collected as part of a promotion.] This smoothing spray works well, it is effective in sleeking back hair and keeping fly-aways at bay. Also works well after a blowout.
At first the scent was beautiful, almost like a hair mist. But as the day went by it was so strong that it gave me a headache.
It also flakes/turns white and there is no way around it.
Effective, but won’t purchase again because of the cons listed above.

Soft fly away free hair
[This review was collected as part of a promotion.] I tried this product 2 ways. The first was sectioning my hair and blow drying according to the instructions with a warm heat. Which left it dry but a bit wild looking. It didn’t look curly or straight. I decided to go to the flat iron option where I sectioned my hair and straightened as normal. My hair is now beautifully straight and feels “touch me” soft. It does have an odor but it reminds me of vanilla. The product comes in a spray can which allows for easy application.

Great for frizzy hair
[This review was collected as part of a promotion.] I have really frizzy hair and this Texas heat hasn’t helped that at all. I was hoping this would help a little, but while blow drying I saw that the frizz was cut down tremendously ! After straightening my hair, it is so manageable with no frizz and that is amazing ! It smells so good kind of vanilla marshmallow like to me & I will definitley keep this in my stash !
