Achieving volume like Rachel McAdams‘ can be simple if you wash and condition your hair with products that contain the right ingredients, before even using styling products, especially if your hair is fine or slightly oily.
Hair friction, which contributes to how manageable your hair is, can affect volume, too. When the hair fibers are rough, there is more friction between the hair shafts. But when they are smooth, the surface of the cuticle is smooth and gaps between the shafts are reduced, making hair easier to style.
So, what ingredients should you use to achieve volume? Look for proteins like wheat, starches like rice and corn, anionic and cationic polymers, which bind to the hair for fullness, and peppermint, which stimulates the root, making the hair follicle stick out of the scalp more to create lift.
Since most stylists recommend not washing your hair every day, a dry shampoo is another option for adding instant volume at the roots and absorbing excess oil that weighs down hair. Also keep in mind that if your hair is colored or damaged, volume-enhancing products may dry out your locks.
