Favorite!

This is by far my favorite hair product. Smells great and really does cut my drying time for my thick, wavy hair. The lotion also keeps my hair smooth (with just my hairdryer and fingers) when I'm doing a blowout.

This stuff is amazing!!!
SampledPurchased

I have thick hair, and it usually takes forever to dry. I use this lotion on my hair and it cuts my blow dry time in half! It smells amazing as well. I got it a couple months ago in a box it lasted a while, and I just bought a full size bottle. So I am sure the full size will last so much longer. Defiantly worth the money!

Fantastic!
Purchased

I will be making this a part of my blow drying purchases. This stuff is fantastic. I would not have believed that a little heat protecting lotion could make such a difference.

Thanks, Birchbox!

the literal worst

i tried out a sample, and as others have noted, it gets tacky and almost gel like quickly. running my round brush through it was a disaster. and all i could do was make faces and cry while i was blowing out my hair. i had just washed it for the week, and you know what a pain it is to wash long hair so i just decided to grin and bear it. my hair was not as smooth as it could have been, and even two days later, there is slight tension in the strands as when I run my fingers through my hair. all around gross.

Fine but nothing exciting
Sampled

This product was fine, but I didn't really notice a difference so I will probably not go through the effort of continuing use. The cheaper and more accessible brands achieve the same results.

Number 4 blow dry lotion

Such a great product! Nice scent and a tiny amount adds nice body and volume to my hair. Not sticky or greasy, I think I found a new must have product

great for my fine hair, especially in humidity
Sampled

I have very fine hair and not a lot of it. Any moisture in the atmosphere makes my hair kink up no matter the product. I used this all summer and it was great! My hair stayed mostly straight as I used my hairdryer, including my bangs.

Heavy product
Sampled

I have thick, straight hair and this did not seem to be an approriate product for my hair type. I used it on damp hair and blowdried. It made my hair feeling loaded with product.
