I love how shiny and beautiful it made my hair look, without looking greasy! I always struggle with these kinds of sprays for that reason, but IGK knocked it out of the park!

WHAT IT IS
Spirulina protein in IGK Good Behavior Smoothing Spray strengthens and nourishes hair, while a unique formaldehyde-free bonding polymer, activated by heat, emulates keratin treatment's smoothing effects. This spray reduces blow-drying time, and offers protection against humidity, heat, and UV damage, ensuring soft, shiny, frizz-free hair with 24-hour frizz control and 450°F heat protection.
PRO TIP
“The best part about Good Behavior Smoothing Spray is that you can use it any time you heat style. Whether your hair is damp or you need to refresh dry, day 3 hair with an iron, just apply it generously and style!”
