  • For best results, you should use Sleek & Shine Anti-Frizz Heat Protectant on damp hair before blow-drying. It is formulated to activate with heat to provide maximum frizz control.
  • Sleek & Shine Heat Protectant hair shine spray works for all hair types and textures, and is especially effective on frizzy and unruly hair. It’s one of the most versatile anti-frizz hair sprays because it suits all styles, from straight and wavy to curly and coily.
