GOOD BEHAVIOR Spirulina Protein Smoothing Spray | Frizz Control + Heat Protectant | Vegan + Cruelty Free | 5.6 Oz

I have tried many different anti frizz products and this one by far works the best for me. I have fine naturally straight hair that is prone to frizz and needs to be blown dry. I section my hair and spray this on before drying with a flat brush and it works amazingly well! I do not need to flat iron after blow drying anymore. It does have a strong smell while applying that dissipates and is not overpowering when done styling. Hair does not feel sticky at all afterwards - feels very soft and light!

To start this review off I will say I have Irish curls. I've tried everything under the sun. This product is unbelievable. I can use it to flat iron or just for a bow out. Results are amazing. It will last for a few days without frizz. I even flat ironed my hair using it once and it rained that day!!!! A curly haired girls frizz nightmare!!!! BUT my hair never frizzed and remained straight. I did do a small touch up on my hair as a precautionary but really didn't need to. Amazing product and smells great. 100% recommend it!

I absolutely love this product! The IGK Good Behavior Spirulina Protein Smoothing Spray works amazingly well—my hair feels smooth, frizz-free, and protected from heat without feeling heavy or greasy. It truly gives that “keratin-like” finish and makes styling so much easier. I loved it so much that I bought it for both of my teenage daughters, and it’s been a win for all of us. Their hair looks smoother, healthier, and way more manageable, even with regular heat styling. Huge bonus points for being vegan and cruelty-free. This is now a staple in our household—highly recommend! 💖✨

I have been using it for a little over a week now and so far I like it a lot. This is the product my hairdresser recommended when I asked him for something that I can use on dry or already styled hair that I need to do touch ups on. It leaves my hair shinny and with less frizz. The smells is something I have to get used to even though I was told it smelled good, I find it smells fragranced with chemicals, but nothing terrible.

Good product, protects my hair when straightening. Smells nice

I think they’ve changed the formula. I was buying this mostly because it smelled like vanilla cupcakes. Now it just smells like some sort of perfumed product. Not exactly good, but not bad either. It’s alright. Does the job. Might move on to something more affordable though, because it does go quick if you style your hair often.

I am a repeat buyer. I spray it on right before blow drying and my hair comes out nice and smooth. I love the smell and it doesn’t weight my hair down or make it greasy. Definitely my go to when blow drying.

I hate when it feels like there is product in my hair and this one passes the test. I love this one! I spray it either in the last few minutes of blow drying, or I spray it in strands of hair when I’m using the straightener. I have naturally curly/frizzy hair and this leaves my hair smooth and shiny, with no residue or extra weight to my hair.
