This is not a spray

This product is equivalent to a non aerosol stream. The stream is impossible to target on your hairstrand before using your hot tool. lt is so silly that you stream it on your face, so do makeup after hair when using this. Due to the ridiculous precision of aim required l use my hand to lift my hair and shoot away. l then use my hand to smooth the product evenly, then run a flat brush to even out. You must blanket cover and smooth this. After that you can finally style. lt does protect and aid somewhat to holding the hairstyle. l wish they would make this into a spray. This stream on a single section via nozzle as per directions is almost universally impossible and for practical purposes universally stupid.

Thermal Spray

This worked great with my flat iron. It's helped with my ends.

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.

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.
