More Hair Volume: Hair Curvature

This one is pretty simple. Curved or curled hair takes up more space than straight hair, as shown in this diagram.

Hair Science Advice

Be sure to use a foundation styler like mousse or gel to help set the curve. Heat makes the styling polymers melt and flow to increase hair-to-hair contact and provide even better long-lasting hold.

Hair Style Advice

Enhancing your hair's natural curls or waves is an easy way to create long-lasting hair volume. Use a round brush or shape your hair into a curve around your fingers to help lift the roots. Use a curling iron to add volume to hair ends.
