Sleek and shines

I like this brand. A lot. I am not a fan of how this spray smells at first when you just smell it in the air, but then something magical happens and it suddenly doesn't smell like anything in your hair. So that's odd to me but since i like how it works, it was a nice surprise.

Great product!

This product makes your hair so soft! I blow-dry and straighten my hair every day and it usually looks so dry on the ends. This product protects my hair and allows me to go through my normal routine without the dry ends. So great!

Number 4 Thermal Styling Spray Review

Prior to subscribing to Birchbox I have never used a thermal styling spray and since I've been a member I've received a few and I love them all. So I don't have anything negative to say about the Number 4 styling spray. My hair is thin and frizzy and it tames it pretty well after a shower. Decent product/nothing negative to say

nice

This was a good product. I like the smell. It had a little bit of a hair spray texture after use. Holds my flyaways down after using my flat iron.

Thermal Spray

I enjoyed this thermal spray, thought it worked well with my long hair. Works well when using either my flat iron or curling iron, holds down the frizz.

Works great on dry frizzy hair

I've used similar products that left my hair feeling dry. I felt like this one really left my hair shiny and soft after heat-styling. I would recommend it.

I'm in love with how smooth my hair feels when I use this product. The smell isn't my favorite but it doesn't linger

Nothing to write home about

This product did nothing for me. It didn't help that I had to put a new nozzle on it before I could even try it. I didn't see where it help conditioning my hair as I used the flat iron.

Works great on my hair

I like this product because it doesn't leave a stinky residue on my thin hair. It makes it style nicely.
