IGK Good Behavior Spirulina Smoothing Blowout Balm is a heat-activated balm. The formula starts as a thick cream and melts into the hair when heat is applied, this gives the hair sleekness and shine without weighing it down. It helps to fight off frizz, protects against heat damage and provides a smoothing effect like that of a Keratin treatment. This product is great for those with curly and wavy hair to keep your sleek, smooth style in place and controlled!
