KERATIN RESEARCH Thermal Hair Protector Spray - Enhances Shine, Eliminates Frizz, Detangles, Prevents Split Ends, Replenishes Nutrients, Heat Activated for Styling

I use this product all the time. I feel like it helps protect my hair from damage when I blow dry it. It's very easy to use and has a pleasant scent. It helps make my hair smooth and shiny. It's not an oily spray, which is great. The size of the bottle is small but it lasts a while. It's a good value for the money.

The best way to use the spray for me, was to focus on the pieces that have been bleached and a light spritz on the rest. I combed it through damp hair. I let my hair dry and used a flat iron. It came out beautifully. No frizz, shiney and perfectly straight. Thank you to customer service!

The spray has replaced my need for conditioner while it protects my hair when I blow it dry.

Seems to work well on my hair, no stickiness or weighed down feeling after drying hair - my only complaint is the spray bottle is difficult to pump for arthritic fingers (but that's my problem).

I’ve tried a bunch of heat protectant sprays, but this one really impressed me. It makes my hair feel super soft and shiny without that greasy or sticky feeling. I spray it before blow drying or straightening, and my hair stays smooth and frizz-free all day. It also smells amazing — clean and fresh, not overpowering. I’ve noticed fewer split ends and way less dryness since I started using it. Definitely one of those products that actually does what it says. Total win.

This stuff if awesome!!!!!!

Product size has changed based on prior orders but the price has gone up. Value for money is questionable

This stuff is great! I have 2a hair and it doesn't weigh it down or make it feel oily. I usually spray it in after towel drying, let it air dry for a while and then either use my blow dry brush to wear it straight or some curl cream and diffuse to wear wavy, and my hair feels healthy. The smell isn't bad either. The bottle is kind of small though.
