Teasing a ponytail creates an interesting effect that adds shape to an otherwise simplistic hairstyle. Brush your hair back and secure it in a ponytail holder. Brush through it with your fingers to straighten it out. Hold the ponytail erect and brush the hair down with a comb so it creates a tangled fluff. Spray the hair lightly with hair spray to hold the tangled fluff in place. Continue fluffing and teasing the hair in the ponytail until you achieve the volume you desire.
A tall hairstyle can make your face seem thinner while keeping the hair away from your face. Lift the hair at the crown of your head and "back-comb" it, or comb it downward toward the scalp. Start with the hair at the back of the crown of your head. Slowly move forward to your front hairline. Leave about an inch of hair near the hairline straight. Pull your teased hair back over your head, creating a bump. Pull the smooth hair near your hairline over the teased hair and secure it all back with a clip. This creates a soft bump on the top of the head, which alters the facial look for your character.
When aiming for a dirty, erratic look for your character, teasing can give you the desired effect. Leave the hair down and tease it at random locations to create a disheveled look that works well for a character that has just experienced a traumatic event, just woke up or lives in squalor. Allow the hair to hang over the face for an added appearance of disarray. Use hair spray on the tangles of hair to keep them that way throughout the act.
Keep the hair away from your face unless the script calls for it to be in your face. Keep the hair back with simple bobby pins or hold it all back with a decorative headband. Match all hair accessories to the outfit for the sake of stage appeal. Use strong hairstyling products that can withstand the intense heat of the lights without letting the hairstyle go limp. Be ready to touch the hair up whenever you leave the stage.
