Start with towel-dried hair and spray generously, making sure hair is fully covered at the surface, underneath, and at the roots. Use more or less of this blow-out spray depending on hair length and thickness, and comb through to distribute evenly from root to tip. Style hair using a blow-dryer until completely dry. For an even fuller blow dry, apply a few more sprays to almost dry hair and continue blowing dry with a round brush, focusing the heat of the dryer on the brush.
