- GOOD BEHAVIOR Spirulina Protein Smoothing Spray | Keratin Like Treatment + Frizz Control + Heat Protectant | Vegan + Cruelty Free |

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!

This Protein Smoothing Spray is fantastic! It leaves my hair feeling soft, smooth, and manageable without weighing it down. Frizz is noticeably reduced, and my hair has a healthy shine after each use. The spray is easy to apply, smells great, and makes styling so much easier. Definitely a must-have for anyone looking to tame frizz and improve hair texture.

This is worth the hype . It’s a bit “ fumey “ but I can tolerate it with having asthma .

I used this on my thick, long hair and really liked how it made my hair feel smoother and more manageable, especially when blow drying. It helped with frizz and didn’t weigh my hair down or feel sticky. AND IT SMELLED AMAZING! The only downside is that it didn’t last me very long, probably because I needed to use a bit more product with my hair type. Still, it worked well while I had it and did what it claimed.

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.

Great product . I have frizzy hair , that I blow dry & straighten . The product protects my hair , and leaves it smooth loooking .

Amazing! Buy this product! I’m just upset I didn’t purchase the larger size! This was the first time trying anything from IGK and I’m so glad I did. The scent is fabulous, it is a perfume for your hair and it leaves your hair smooth and manageable. I can feel the way it protects my hair, no frizziness that usually comes with blow drying. Great purchase.

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.
