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.

Worth the price
Purchased

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.

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.

Love it!

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!
