My new HG smoothing spray!!
This is my new HG smoothing spray!!! If I blow dry my hair and style immediately (rarely happens) I don't have to worry too much about frizz but my hair holds a curl for days and the frizz just gets crazier as the days pass. Because of this, even when my hair has a nice curl, it never looks as good ...

Too harsh
The main ingredient is alcohol and it is way too harsh on my hair. First time I tried it I washed and conditioned with bars. I then let my hair air dry just a bit and sprayed the smoothing spray.

BEST Behavior!
Hair Type Wavy Hair
[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!
Hair Type Wavy Hair
[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.
