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.

Wasn't a Fan

While I have loved all other No. 4 products I have tried from BB, this one falls short. The smell is amazing, but like others said, the nozzle is very weird. I also have very fine hair, and this product seemed to make it feel more weighed down when I used it.

Didn't like.

The smell on this product was too overpowering for me. I had a headache all day from the smell. It did seem to control my hair, so if you can take the smell, go for it.

Ok

I already have a styling spray that I love but this product was nice to try out if you haven't found that special product that works for you yet.

When I straighten my hair I'm always in search of the product that will protect it from the heat. This product had my back!

Lack of use
Sampled

Low rating is pretty much because I never style my hair so rarely use the thermal styling spray. On the rare occasions I do blow dry my hair I forget to use it.
