BEST IGK PRODUCT BY FAR!

Great product! Reduces frizz + amazing smell + leaves hair with a silk like finish, but doesn’t make oily.

Silky Locks!

I received this product complementary for testing purposes from Influenster, And I am happy to say that I would purchase this on my own now since trying it out. I have less frizz when I apply pre blow dry, and softer locks when I apply after styling. Thankful for this product!

Good Behavior 4-in-1 PrepSmoothing Spray

The idea of GOOD BEHAVIOR came from the needs of our IGK salon clients, as the demand for chemical Keratin treatments were constantly being requested. The founders came together to create a product that our clients can take home. GOOD BEHAVIOR is safer, easier, and more cost effective than Keratin.
