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...

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!!

Good!
Hair Type Straight Hair
[I received this product in exchange for my honest review] This product worked well and it did deliver on its promises/claims. It did a good job at smoothing my hair and helping with flyaways/ styling. The only reason I had to take a star off is it felt a little bit too heavy for my hair type and it almost made my scalp feel oily. Otherwise great product

Love this product and will buy again and again
Hair Type Straight Hair
I am trying this product for the first time. Love this product so far. No complaints. It helps smooth frizz without feeling heavy and sticky. I am so impressed with the results. I would definitely recommend this product to my family and friends. No damage or dryness noticed in the past three weeks.

So silky!
Hair Type Straight Hair
[I received this product in exchange for my honest review] My hair is so straight and smooth after using this spray. Pictures do not do justice. It was simple to use . A little goes a long way. I can't speak for longevity but so far it has held up.

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
