To wake up in the morning with full, voluminous hair that's ready to go with minimal fuss, try this trick at night before you go to bed. Spritz a thickening spray onto wet hair. Pull your hair back into a high ponytail and twist it to make a loose bun. Bobby pin or clip the bun in place. Sleep. In the morning, take out the pins or clips and comb through your hair with your fingers. Don't use a comb or brush -- it will give you a major case of the frizzies.
