Blow drying is an effective technique used to add volume to hair because it involves lifting the roots while directing airflow from a blow dryer. This method allows the hair to expand as it's dried, creating a fuller appearance. By using a round brush in conjunction with blow drying, stylists can create additional body and movement, enhancing the overall volume.

In addition to generating volume, blow drying can also improve the hair's texture and smoothness, making it more manageable. This technique is especially useful for individuals with fine or limp hair, as it helps to achieve a bouncier and more voluminous look.

The other techniques listed serve different purposes. Flat ironing is primarily used for straightening hair and achieving a sleek finish. Curling adds waves or curls but can create more structure rather than volume. Highlighting is a coloring technique that adds dimension and lightness to hair without directly contributing to volume. Understanding the specific impact of each technique is essential for achieving desired hairstyles and making informed decisions during hair styling processes.
