IGK GOOD BEHAVIOR Spirulina Protein Smoothing Spray Travel | Keratin Like Treatment + Frizz Control + Heat Protectant | Vegan + Cruelty Free | 2.4 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!

Addicted to this amazing product and always have a full size and travel size on deck. The smell is incredible and soft - constant compliments asking me “what is that fabulous smell?” It’s effective on both damp and dry hair and great when you want a refresher. Hair looks healthier and shines! Highly recommend!

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 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.

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.

This is my favorite hair Protectant spray and I have repurchased several times. It has a nice scent and I feel really makes a difference in protecting my hair against heat styling. It is not sticky and it does not leave my hair with a rough texture.

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 naturally curly hair that likes to get frizzy in humidity. I’ve used this spray prior to flat ironing or curling, occasionally also as a humidity protectant. I love that it works well to lock out humidity and keeps the shine in. What could be improved is the scent. When applying, I have learned to do a few sprays with my face covered and holding my breath, step out of the room to breathe, and come back in the room after a few minutes if I need more product (similar to dry shampoo). It’s that strong when applied. Overall, it’s an amazing product that locks in shine, locks out humidity, and is heavily scented when applied.

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

The best product ive ever tried! It leaves my hairs smooth!

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.
