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.

Spray it and brushed my hair after the shower! And wow it smells good I have used it for a month and my frizz is almost non-existent when it dries. My hair looks so tame and full! I would buy again!

Looking good, smelling great!
Hair Type Wavy Hair
[I received this product in exchange for my honest review] This product smells divine! My fiancé loves the scent and this leaves my hair looking shiny and healthy. The scent lasts all day and the results speak for themselves. This is my first time using an IGK product and I'm really impressed with the quality and feel. Would definitely recommend!

Great spray!
Hair Type Wavy Hair
[I received this product in exchange for my honest review] Definitely makes my hair not as frizzy and last all day. It's a very light spray and has a great hold. The smell is nice but kind of too strong. I would recommend just don't spray too much all at once.
Product is Fine, Scent is Awful
Hair Type Very Curly Hair
[I received this product in exchange for my honest review] I really did not like the way it smells that it was so off putting. I think this type of formula as an aerosol is just not my preference. The performance of the product is fine, but I wasn't wow'd by it.

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
