Good Behavior smoothing spray reproduces the smoothing and sheathing effects of a keratin treatment when activated by heat. Thanks to a formula enriched with spirulina proteins and binding polymers, it leaves hair soft, shiny and frizz-free. Safe for chemically treated hair, this spray also offers heat and UV protection, ensuring optimal frizz control and brilliant shine.

Mist over damp hair in sections. Comb through, ensuring every strand is thoroughly coated from root to tip. Blow-dry in sections to seal in the treatment with heat. Style as usual or apply again and finish with a flat iron for maximum smoothing.
