IGK Good Behavior Spirulina Protein Smoothing Spray is a Keratin-like treatment in a can. This heat-activated spray mimics the smoothing and anti-frizz results of a keratin treatment. 24-hour frizz control and 450F heat protection. Spirulina protein strengthens and nourishes while an innovative formaldehyde free bonding polymer mimics the coating and smoothing properties of a keratin treatment when activated by heat. Good Behavior also helps to cut down on blow-drying time and helps to protect against humidity, heat and UV damage, leaving hair soft, shiny and frizz-free. The lightweight formula is suitable for all hair types-and coarse hair, natural curls and waves stay relaxed until the next shampoo.
