Great for Frizzy Hair
Sampled

I rarely blow dry my hair, and the few times I have I've used this product. I avoid blow drying because it frizzes out so badly. This really worked well, though, at maintaining my course hair. Will be purchasing.

Great Styling Product
SampledPurchased

This product is great for curly hair and to beat the humidity! I also love the way it smells. I would give it more stars but I feel like it could hold my hair a bit better. It makes my hair less frizzy but also I feel like it doesn't really hold the curl. Just leaves my hair wavy. The smell outbeats it all!

Not what I expected. Very very heavy spray. Smells good enough, I was hoping for something a bit more like a dry oil. I'very used this several times trying to love it....hasn't happened yet

Works
Sampled

Smells great and works. I am always skeptical of products claiming to tame frizz. It takes a lot to tame my frizzy hair. But this works well. Made my hair softer and smells great. I feel like it took less time to dry my hair, too.

effective but oily
Sampled

this spray was effective at making my hair glossy and sleek but be warned that it's rather slick and will leave your hair feeling oily. i prefer the beauty protector brand,which is also sold from birchbox.

that being said, if you're going for a very sleek or even wet look, this might be the product for you. if you're just looking for manageability, you might want to look elsewhere.

I got this in one of my monthly boxes and thought it was great. Few sprays, finish up with heat appliances and hair looks great.

Leaves hair feeling dry, but provides plenty of volume when styling.
Sampled

This product makes my hair feel excessively dry compared to other products that I have used. It does however, give my hair plenty of body when styling.
