For volume and lift, mist near the roots and direct the hair away from the scalp. For shine and staying power, hold can 10 - 12 inches from dry hair.
Depending on how long you hold the spray for, depends on the amount of hold you get. Need lighter, more workable hold? Lightly mist for 1-3 seconds. Need rock-solid, ain't-budgin hair? Mist for 4-6 seconds.
