IGK 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

For some reason, this took forever to be shipped. I'd seen the videos on social media and was excited to try it, so the wait was torturous. I used it on my first blow out after it was delivered. I have fine hair, so I errored on the side of caution and could have used more. The smell is just okay, but the fumes from the aerosol are absolutely awful. It legit makes breathing hard and my lungs are not a fan. I have to hold my breath before spraying, apply, and quickly escape the room to let it dissipate. I'm convinced that it works on my hair, but the fumes are toxic. I've used this about half a dozen times and I've learned that I need to be pretty precise with my application: I have fine hair, so too much close to my roots or on the top layer of my hair and it looks greasy, too little and I may as well not have used any, but if I get it *just* right? Shiny perfection! Would I buy this again? Maybe, but I'd only purchase from my beauty supply store where they sell it at half the retail cost, and I won't use it daily because the fumes seriously do make breathing a challenge. It does work and people with thicker or drier hair may find it a lot more forgiving when it comes to applying too much.

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.

Leaves hair shiny but the fragrance is a deal breaker. It’s so unpleasant for me personally.

Me encanta el aroma, la textura es muy ligera, el spray arroja el producto de manera uniforme en el cabello y el contenedor tiene bastante producto. Sin duda lo volveria comprar

Excellent product but far too expensive. Wish I could commit to buying again, for now I’ll be looking for a UK alternative.

Just fyi this is very small and not worth the price. You can get a bigger one for way cheaper. Big waste of money i wish i could return it.

Works well. Helps when my hair is staticky and my partner says it smells good.
