I have naturally wavy and frizzy hair that I straighten at least twice a week. The first time I used this product I learned that less is more. I couldn't run my fingers through my hair so the second time around I used it sparingly and the results were amazing. My hair was soft and even looked like I went to a salon.

What's up with that nozzle?
Purchased

Don't get me wrong, I LOVE this product. It provides great protection when curling/flat ironing my hair and it gives just the right amount of hold, but that spray nozzle! The other reviews are spot on when they say it comes out in a stream. I wish they would revamp this feature so that the spray was a mist, then this would definitely be a 5-star product!

Jet stream spray
Purchased

This product works okay- I have used it on wet and dry hair with good results both ways. (Curling iron waves stay pretty well and I THINK it helps protect my hair when blow drying.) However, especially when I use it on dry hair, I have to spray it on my hands first to distribute it, because the spray shoots straight out, instead of a finer mist. It makes it really hard to evenly distribute and I have even accidentally gotten an earful because of it. Yuck!

great product- poor packaging
Purchased

I love this product- the way it makes my curly hair sleek and silky after I use a flat iron and blowdryer on it.
However, I find the container to be difficult to spray with one hand and impossible if your hands are wet or slippery after a shower. I have to use both hands to grasp it and press down the nozzle! the design aesthetic is nice- sleek cylinder black and white- but not functional.

No more frizz!

Usually when I blow dry my hair it looks like an 80s nightmare, but this stuff definitely tamed it. Great product.

Ok

I didn't like the scent. It was a good product and I've enjoyed some of their other scents but this one was not for me.

I like the scent but I didn't love the texture of my hair after curling my hair.
