I was really excited to find this in my May box. Especially since I'd just gotten my hair colored and didn't want to fry it. Maybe it was just a pump malfunction, but it seemed that no matter how far away I sprayed, my hair would be completely saturated with product, meaning I would have to run my flat iron over my hair two or three times. The upside is my hair looked smooth and sleek, which is especially great living in the humidity ridden south. Overall, I didn't love it and probably wouldn't purchase. But, I will definitely finish up the bottle.

I don't heat style, so I used this like a leave-in conditioner. I cannot Gove an accurate review of this product as intended.

I'm not usually a hairspray fan, but I would actually use this one. And bonus, it's natural. I would consider purchasing this when I run out.

I have fine hair and this left my hair feeling thick, full and easy to style. A little went a long way. I loved the smell and I will definitely consider purchasing this product in full.

I use this spray a lot because I use a blowdryer, straightener, and curling wand. It smells good and helps keep my hair healthy.

Great product!

I have been using this product since i received it in May and I love it! I straighten my hair everyday and I really feel like it protects my hair a little. Helps with the damage to my spilt ends. I would recommend this to anyone that straightens or curls their hair.

Clogged nozzle
Sampled

I really want to like this product, but I'm not sure if it's the nozzle or the product that keeps clogging. It's really hard to get out of the bottle.

Good hold

This was a pretty good spray. I straighten my hair regularly and this spray kept my hair shiny. I also like that is free of sulfates and parabens!

Smells like cologne
Sampled

Smells like men's cologne and cheap cologne at that. Also not a fan of the way it left my hair feeling. It stayed pretty stiff. Got it one time before in my box. Was not impressed then either.
