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.

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.

Love this

This was great for my hair. I used it on my wet hair. My style stays all day. I am going to buy this right now. I hope the nozzle works good. I see other reviews saying the full size sprays weird.
I will have to try it on my dry hair once I get it. Maybe I will be able to straighten my hair with better results.

I have been using this in conjunction with another anti-breakage serum. I definitely see a difference in the smoothness of my stick straight hair and hope with continual use, it will help with the breakage I am seeing from too much straightening.

I love this spray! I need texture badly and this Thermal Styling spray provide just that. I have several other samples of other products, but this is by far my favorite! I will most likely use up all my other samples and then buy a full size of this one!

I'm obsessed with the smell
Even if it doesn't help control my frizz on humid days
