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

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 can’t live without this spray! It’s almost as good as an expensive salon keratin treatment. I apply it prior to flat ironing and it makes my hair extra smooth, straight and shiny.

I preface this with the fact that I have naturally curly hair that is coarse and thick. (Picture 1 is of my hair on a “normal” day. ) I read several complaints about fragrance. It does have a fragrance. I can see how some may not like it. I’m fine with it. Has an underlying black pepper scent. I Don’t find it unpleasant. It’s an aerosol so, yup, spray and hold your breath like you would hairspray. It’s a “protein” spray so I did expect it to make my hair feel a little stiff I used it exactly as recommended. I did pair it with the IGK Expensive Clear Gloss Too Coat in the shower. My hair dried in 50% of the time it normally takes so that is a plus. I used a brush blowdryer. I think it did what it is suppose to do. Why it gets 3 stars is that the claims it makes are unrealistic. I cannot just walk out the door after blowdrying. It’s a frizzy mess. (Picture 2) (Although better than what it would be without it ) I will still need to flat iron it. I’m in my late 50’s and have tried virtually every product imaginable in my 59 years I think it earns 3 stars. It’s an average product with unreasonable claims for me. 3rd picture is after flat iron and no other products used on it yet. I typically use a moroccan oil after
