Soft, shiny, and frizz -free hair in just one step
[This review was collected as part of a promotion.] I really loved this smoothing spray! It leaves my hair soft, shiny, and easy to brush without feeling heavy or sticky. The texture is lightweight, and it helps control frizz while protecting my hair from heat. The packaging is practical, and the results last all day. I definitely recommend this product to anyone looking for smooth and healthy looking hair

Smells toxic!!
If I cooks five zero stars, I would. This product smells horrible and full of chlorofluorocarbons. And it doesn't even work all that well.

Decent
[This review was collected as part of a promotion.] Pretty good! Doesn’t weigh down the hair and gives a good shine. I like the mist spray vs the typical spray bottle, helped distribute better especially since you can spray continuously.

Great
[This review was collected as part of a promotion.] I’ve been using IGK’s good behavior smoothing spray for a little while now and I’m honestly impressed. My hair usually gets frizzy when there’s humidity but this helps so much.

Smells great, looks flat
[This review was collected as part of a promotion.] This has been really good in terms of frizz prevention, and it smells great. My only problem is it leaves my hair feeling a little oily and flat. That it is in an aerosol can kinda sucks too because I have to use all the product before tossing.

Awesome!
[This review was collected as part of a promotion.] We love this styling smoothing spray. It’s supposedly mimics the look of a keratin treatment. Now, I have never done keratin treatment so I can’t compare to that. But the good behavior spray does an amazing job smoothing the hair without it feeling sticky. I am even able to brush the hair after application and it stays smooth and shiny. The smell is somewhat sweet but I guess that’s how all the hair sprays usually smell. But it gives you that “after the salon” feel and smell.

Not too shabby
[This review was collected as part of a promotion.] I used this on my hair before blow drying. I didn’t really separate my hair out in sections, just kinda lifted my hair and sprayed on top of it and underneath it. Overall it made my hair smooth and controlled all the frizz!! I don’t love the way it smells. It also made my hair feel kind of weighed down and like you could feel that there was product in it. Maybe I put too much? Either way, I would recommend this for sporadic use.
