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...

IGK Good Behavior Smoothing Spray
Hair Type Wavy Hair
[I received this product in exchange for my honest review] I've been loving the igk good behavior smoothing spray. It leaves my hair feeling incredibly soft, smooth and noticeably less frizzy without weighing it down. I also love that it doubles as a heat protectant so I can style my hair while helping protect it from heat damage. The spray is lightweight, easy to apply and gives my hair a sleek, shiny finish that lasts. My hair looks healthier and feels so much more manageable after using it.




Sweet smell
Hair Type Wavy Hair
[I received this product in exchange for my honest review] Unfortunately I was unable to really use this as intended so I do not have any before or after pictures. The smell was too sweet for me it upset my stomach to the point that I could not spray more. My husband said it smelt like marshmallows, it was really just a super sweet smell to me.
Excellent frizz control, strong fragrance
Hair Type Straight Hair
[I received this product in exchange for my honest review] Pros: Leaves my hair incredibly sleek, adds volume, cuts down on blow dry time, provides incredible heat protection. Cons: The scent is not to my personal preference and lingers a bit. Overall: If you're sensitive to strong fragrances, keep that in mind. But if you're just looking for performance to get a smooth, shiny blowout, this spray absolutely works.

Smoothing frizz control for fine hair!
[I received this product in exchange for my honest review] The Good Behavior Smoothing Spray by IGK is an overall great product. I used it for the first time for my daughter's Pre-K Graduation, which was a very humid and rainy day. It worked really well to keep the frizz down (photo posted is from after we arrived home from the graduation). It did not make my hair feel greasy, which I always get worried about when trying new products as my hair tends to be on the oily side at the roots. Additionally with having fine hair, it did not weigh my hair down, which was a plus. I would definitely recommend this product to others.


Made It To Day Three Frizz Free
Hair Type Straight Hair
[I received this product in exchange for my honest review] I'm in love with this product! I live in an incredibly hot and humid area, but was able to get to day three of my hair being frizz free! Application is a breeze with a fine mist & not a bad smell at all!

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
