If you were born with hair lacking volume and ooomph, you can trick your tresses into thinking they are bigger and thicker than they actually are with a few styling techniques. Plump up your roots with your favorite styling product and a variable setting blow dryer.
Bend Over
Blow dry your hair while hanging your head downward to give your crown lift. Start with damp, conditioned hair and apply styling product from your fingers to your hair, making sure to get good coverage of your product at the roots. Massage your scalp with one hand while holding the blow dryer to your hair on a low to medium setting. Keep your head in this position until your hair is dry, then blast it with a shot of cold air to set it.
Clip Up Your Roots
Apply your favorite styling product to damp hair, making sure your product is distributed specifically at your roots. Lift a section of your hair with one hand and insert a long narrow clip at the scalp so the hair stands up. Position the blow dryer a few inches away and turn the blow dryer on low to medium. The hair will dry upward at the root to give you maximum volume. Release your hair from the clip after it is dry. Make sure you don't use a high heat; if your clip is metal, you could burn your scalp.
Alternate Hot and Cold
Blow dry your hair with a large round brush, lifting the hair up and away at the roots. Wind the hair so that it curls around the brush. Turn the blow dryer on a hot setting and keep the dryer pointed at the brush until it is dry and body is formed. Finish the style by giving it a blast of cold air. The heat from the blow dryer opens the cuticle, allowing the hair to be styled. The cold air closes the cuticle to help lock in the volume. Repeat hot and cold all over the head to create lift and bounce.
Opposite Direction
Dry your hair in the opposite direction of your final style. If your hair is normally parted on the left, comb your hair over from the right side of your head and blow it in this position, concentrating the heat at the roots to give volume and fullness. Keep the blow dryer on a low to medium setting throughout the styling process. When your hair is almost dry, blow dry the hair in the right direction, lifting the hair away from the scalp. Make sure you use a vented brush so that the air can reach the scalp.
