Directions: Shake well before use. On washed, towel-dried hair, detangle and divide the hair into two sections. Spray the product into your hands, starting with 2–4 sprays for thin to medium hair or 6–8 sprays for thicker hair. Rub hands together and distribute evenly through the lengths and ends. Do not rinse. Blow-dry to heat activate the formula, then use a straightening iron for longer-lasting results.
