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

Backcombing near the roots is an effective technique for adding volume to flat hair. This method works by creating tangles and lift at the base of the hair, which gives the appearance of thicker, fuller hair. When backcombing, the hair is gently teased or combed backward, creating a cushion of hair that stands away from the scalp. This technique is particularly useful for styles where volume and body are desired, such as updos or voluminous hairstyles.

Curling with a flat iron can create waves and curls, but it does not inherently add volume at the roots. Shaving the sides may provide a stark contrast that can draw attention to the longer hair on top, but it does not actually contribute to volume. Using straightening products is designed to smooth hair and create a sleek appearance, which often results in less volume rather than more. Therefore, backcombing near the roots stands out as the most effective technique for achieving added volume in flat hair.
