There are so many possibilities, you’ll want to experiment. But always start with a small amount, and add as you go. You can be more generous the thicker your hair is.
For a textured look, apply to the shortest layers first. For a natural look, apply to dry hair (or after heat styling) one section at a time until you achieve the desired effect. For a curly look, apply to wet hair, twirling into each ringlet starting at bottom of head. (Helps control frizz while separating curls.) For hold and volume, apply to roots and/or crown. For sleekness, slick back loose hairs and fly-aways. To keep your hair away from face, apply at hairline.
