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. OMG, I though I had a head full of split ends. Took blow drying and hot iron to get it under control. St...

Makes my hair shiny!
Hair Type Wavy Hair
[I received this product in exchange for my honest review] Check out that shine in my hair! This is amazing at giving my hair that extra oomph! I love that I can apply it when I have damp hair or when I'm styling. I usually do it when my hair is damp. It gives my hair this beautiful shine when I style it and gives my hair volume! It's easy to use too. Keeps my hair tamed and looking amazing every time!

Hair Type Wavy Hair
[I received this product in exchange for my honest review] This IGK good Behavior smoothing spray is my best friend because without it my hair wouldn't be the same. Now i feel my hair smoother and soft. I recommend it

It works!
Hair Type Very Curly Hair
[I received this product in exchange for my honest review] I was really excited to try this! My daughter has very curly frizzy hair and we live in Florida! The humidity is not kind to her hair. Usually by the end of the day her hair has fully curled back up. Using this spray it not only protected her hair from the heat styling but she only needed touch ups in a few areas instead of all over. And her hair was soft and shiny. The spray has a fine mist and distributes nicely. I think this spray is very well worth it!


Great for blowouts!
Hair Type Straight Hair
I received this product in exchange for my honest review. It is super smoothing and left my hair super soft and shiny. My hair is already straight but this helped with flyaways. Neutral scent.

Fresh from the salon feeling with minimum effort!
Hair Type Wavy Hair
[I received this product in exchange for my honest review] This smoothing spray is something I did didn't know I absolutely needed in my life! I am pretty lazy when it comes to my hair, and I rarely have the time to do much more than just throw it up in a claw clip. I also have a bunch of annoying frizzy fly-aways on the top of my head. I was amazed at how easy this was to use, and I barely had to spend any extra time on it! This is my hair only using the spray and a hair dryer for a couple minutes. I could immediately tell that the fizziness was wayyy better than normal. It made my hair super soft and it stayed tamed all day, without needing multiple brushes throughout the day like it usually does. Such a great way to get that fresh out of the salon feel with minimal effort!!

- Asked by Meenah
- Official Answer By IGK - Brand EngageHello! IGK products are formulated without sulfates SLS and SLES (known to break down the bonds used on hair extensions). IGK products should be safe to use on human hair extensions, however, due to the variety of bonding agents on the market, we recommend checking with your stylist - just to be safe! 🖤Was this answer helpful to you
