Instantly Smoothes hair!
When I received the set I was heading out the door. I needed a quick touch up to smooth out my hair as it was frizzy. I sprayed a little bit of the smoothing spray and couldn’t believe how my hair looked after a few sprays. It just smoothed it out without changing the texture of my hair and it wasn’t heavy. It’s not like a dry shampoo it’s totally different. It also set my curls/waves. The next day I tried a dime size of the smoothing balm with the prep spray on one side of my hair and I could believe how much of a difference it made. It quickly smoothed my hair even without using heat! The results are impressive. This is now my favorite haircare line and it feels like it was made for my hair.

Finally!! Shine, Smoothness, and No Frizz
Bought the IGK “So Smooth So Soon” trio during the Anniversary Sale and it delivered. I’d already been using the 4 in 1 prep spray for months as a heat protector, and adding the smoothing spray and balm took everything up a notch. My hair feels smoother, fuller, frizz-free, and shiny.

no more frizz
I’ve tried everything to stop frizz and have a smooth blowout that’s LASTS! A little goes a long way and your hair looks just as good the next day. I’ve been using these products for a couple years now and they work so well with my hair type. So well that my daughter took my products back to college with her so I’m happy to see this full size bundle during the Anniversary Sale and stocked up. What a deal!

Did Not Meet Expectations
I have fine hair and do not like my hair to feel stiff or as though it has a lot of product in it. I style my hair most days so I was looking forward to the IGC Good Behavior products. I used the products after my shower to get ready for work. My hair was difficult to style and felt stiff as though I sprayed super hold hairspray in it before styling. It was awful. It didn't look shiny or smooth and felt awful. I had to take another shower to get the product out. I see many great reviews so maybe it's my hair or my preferences. I don't use hairspray or anything I can feel in my hair. Wish it worked as described, but it's going back after one use.

works great.
I don’t have any issues with this being greasy as others have reported. Been using IGK products for years. I really like them for smoothing and defrizzing.
