Love it!
Sampled

I curl my hair regularly, and that can do some serious damage. This definitely protected my hair and added shine. The smell was great too. I have other heat protect products, but when that's finished, I will definitely be considering this product next!

What a surprise! I put this on my very fine hair when damp. And after blow drying I had a great deal of volume.

Smells great! Used it before I used my hot iron until it ran out. Can't wait to buy the full size

One of my favorites
SampledPurchased

I bought this for my daughter. She has fine, straight hair that she has to curl for cheer. I use a little of this before using the curling iron, and the curls take like magic and stay! Would highly recommend.

Protects and prevents
Sampled

I liked this product. I misted my damp hair before blow drying and again before straight ironing. It helped protect it, I think, and it helped with my frizz. I liked the smell of the product too.

Didn't think this did much
Purchased

Hard to say if this works or not but I found I needed to put it on wet hair and not dry, which I felt defeated the purpose beside protection from a blow dryer.

Curly Hair Day
Sampled

I have extreme curl and uncontrollable frizz. It takes me a good hour to straighten my shoulder-length hair. Usually it immediately shows signs of wave upon any hint of moisture. This product does the best job by far if any product I have ever tried

Too heavy for me
Sampled

I have wavy hair and never ever blow dry it straight (not that skilled!) so this product is a bit heavy for my hair. But it did have a nice texture and maybe one day if I get adventurous, I'll give it a try with a blow-out.

I love number 4
Sampled

I could probably use every number 4 product and love them all, just because the smell is incredible. Not only does it smell good, but It felt like it was actually detangling my hair.

Nice non-heavy spray. Didn't weigh my hair down yet stayed in place for curls
