About this product

IGK Hair's Good Behavior Spirulina Protein Smoothing Spray is a heat-activated hair treatment designed to mimic the smoothing effects of a keratin treatment.

The spray helps minimize blow-drying time and leaves hair soft, shiny, and smooth when used with heat styling. Apply to damp hair, comb through, then blow-dry in sections to seal the formula.
