Hair Volume: Hair Stiffness

The technical term for hair stiffness is "bending modulus." This is a way of measuring the "limpness" of your hair or its ability to hold itself away from your scalp. Unfortunately, stiffness is a direct function of hair thickness. The thinner your hair, the lower the stiffness measure, as indicated in this chart.

Hair Science Advice

Increase the stiffness of your hair mass by using styling products that contain holding polymers. Holding polymers can temporarily improve the stiffness of your hair by bonding together separate hairs - when the hairs work together, they have more natural lift and stiffness.

Hair Style Advice

A good haircut is very important in maximizing your hair's stiffness. Layers and texturizing create opportunities for hair to work together for greater lift and stiffness. To achieve texture, try using a styling wax.
