What technique can be used to add volume to fine hair?

Teasing or backcombing is an effective technique for adding volume to fine hair. This method involves gently using a comb to create a tangle at the roots of the hair, which lifts the hair shafts and creates a fuller appearance. By carefully teasing sections of hair, stylists can create height and texture, making the hair look more voluminous without the need for additional products or permanent alterations.

Layering, while it can provide some texture and movement, may not specifically add volume to fine hair; instead, it can sometimes make the hair appear thinner by removing bulk. Perming can create curls and waves that can enhance volume, but it involves chemical processes that may not be suitable for everyone or desired for specific looks. Straightening, on the other hand, typically reduces volume and emphasizes sleekness, which would not be effective for achieving the goal of adding fullness to fine hair.
