Buy it! Straight & Shiny!

I have tried every straightening product out there and this is fabulous! My hair is straight & shiny. Similar results to a keratin express…I sprayed on after blow drying , then flat ironed small sections at a time, Love this!

Best Serum Ever!

I love all the IGK products but this serum/oil is life changing. My hair was unbelievably soft and smooth. This delivers like no other product I’ve tried.
