Great Shine & frizz killing
[I received this product in exchange for my honest review] Amazing shine. Great shine that helps beat the frizz. Applying this spray keep your hair down with a nice hold without frizz. Leaves your hair nice and not hard like other products.

Hair looking healthier!
[I received this product in exchange for my honest review] Controlling freeze without the heaviness afterwards, i love it. Its heat activated but claims to mimic keratin treatment, i found it good but dont expect to see like quality keratin level change. Once activated (needs heat on damp hair) i can see the shine that it provides too so hair looks healthier. I prefer non scented products but it didnt bother me honestly.

My go to heat protectant
[I received this product in exchange for my honest review] I am loving the IGK Good Behavior Smoothing Spray. It smells so good and protects my hair from the damaging effects of my heat styling. It doesn't weigh down my fine hair and it keeps the frizz at bay even in strong humidity! It's a must for fizzy fine hair like mine.

Works like a charm in this Louisiana humidity
[I received this product in exchange for my honest review] This product works! You don't need too much of it but it definitely made a difference in making my hair less frizzy. I live in Louisiana so it is very humid but this product kept my hair smooth all day. It didn't make my hair heavy. I applied while my hair was damp and after my hair was dried used a flatiron to curl my hair. It is heat activated and worked like a charm.

Not for me
I received this product in exchange for my honest review. This IGK Good Behavior Spirulina Protein Smoothing Spray comes in a metal aerosol can with a plastic cap that snaps on. Since this product is an aerosol, it sprays nicely onto your hair. It does not make your hair, sticky or crunchy. I feel like it left my hair feeling nice and smooth with a slight shine. However, I do not feel like it helped my hair be straightened. It seemed to be protected from the heat as advertised, but I still have bumps in my hair, which would normally have been flat ironed out. The scent of the spray has a slight vanilla scent which stays in your hair for about 1-2 days. I also don't feel like this did much for my frizz. I have thick, wavy hair and don't feel this product is a good fit for me.

BEST Behavior!
[I received this product in exchange for my honest review] Highly impressed! This is the first IGK product I've had/tried, and I would absolutely make the purchase to replace it once I run out. I didn't have to use much at all, and my hair came out so smooth, soft, and shiny. Of course, every review I do, I have to include my opinion of the scent; my hair literally smells edible, like freaking CAKE. YES YES YES!!

Effectively controls frizz!
[I received this product in exchange for my honest review] I love how effectively the Good behavior smoothing spray controls my hair frizz! I love styling my hair and it tends to get dry and frizzy because of heat styling tools! I was intrigued to try this spray to help with frizz and I am happy with how well it worked for my hair type. I use it before styling , on damp hair and my hair looks shiny and smooth after styling. The spray mechanism is effectively designed and easy to use. I appreciate the versatility of the product and it provides effective heat protection! The texture is almost weightless and does not weigh my hair down.
