Number 4™ Thermal Styling Spray Customer Reviews

I have dry, fine, wavy/curly, color treated hair.
So far I have loved every No. 4 product I have tried and purchased. With all the Hype about using/needing a Thermal Protector I really thought I was going to love this. Unfortunately, the end result for me was not what I expected. Because I don't have a lot of experience with Thermal Protectors, maybe I am expecting results that these products aren't suppose to give. My hair felt kind of coarse and blah looking. So, after flat ironing my hair, I misted my hair with a light oil/shine product I normally use on the ends of my hair and it helped. I ended up giving this to my daughter because she likes using this type of product.

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.

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!

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!

I love all of number four brand products. They are phenomenal and I have even purchased some of them through birch box after receiving the sample!

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.

this product smells absolutely amazing and works even better. i think it works better when my hair is still wet, but i've also used it on dry hair. it makes my locks feel like silk. definitely recommend.

I did not like this product. It smells bizarre, and left my hair feeling really sticky. I suppose it would work well for an up-do that you don't want to move at all. But I can't get past the smell to justify even using it for that.

I rally love this product! I always use my flat iron and this helped the first try. I could instantly tell that it was protecting my hair. The only thing I would say that could be better is the spray. It's not so much a mist/spray as much as it is a straight shot out of the bottle. But it's still great and I love not having a greasy feeling to my hair after I use it!!

I have fine hair that's prone to frizz (and I live in a super humid part of the country) and this stuff was a miracle worker! I immediately had to buy it after my sample ran out. It holds my straight and wavy styles, which generally tend to devolve immediately after styling. :) And it definitely made my hair a lot shinier, even after just blow drying. This stuff is great!
