If your roots dry flat against the scalp, try moving the part while they dry. See what your haircut holds before adding a mousse or spray.

Remove excess water first

Press sections gently in a soft towel. Avoid rubbing the ends together. Loosen the towel after blotting so the roots can dry in a different position.

Air-drying: shift the part

Part your hair slightly away from its usual line. Lift the front roots gently with your fingers and leave the lengths alone. Move the part back once the roots are dry.

Blow-drying: work on the roots separately

Let the hair partly air-dry, then choose low or medium heat. Lift small sections with your fingers and keep the dryer moving. Aim the airflow along the hair instead of holding hot air against the scalp.

If the volume drops quickly

Next wash, keep the drying method the same but reserve conditioner for the lengths that need it. Changing one thing at a time helps distinguish a drying issue from product weight.
