Working in sections, spray generously from roots to ends. 3. Blow dry thoroughly to activate and seal in the formula. Pro Tip Perfect blow dry works best on damp hair and requires heat to activate. For best results, do not apply with any other pre-styling products. Some stylists prefer to dispense the product in their hands and rake it through the hair instead of spraying. 1.7 fl oz/50 ml
