Which technique is commonly used to achieve volume in hairstyles?

1. Blow-drying

2. Pin curling

3. Flat ironing

4. Cutting

The correct answer is: Blow-drying

Blow-drying is a widely used technique for achieving volume in hairstyles because it allows stylists to lift the hair at the roots and shape it as it dries. This method involves using a blow dryer along with a round brush or similar tools to create lift and hold in the hair. By directing the airflow from the roots to the ends, blow-drying helps to create a fuller, more voluminous look. While pin curling is also a method that can add some volume, it typically involves setting the hair in curls and requires longer styling time. Flat ironing, on the other hand, is intended to straighten the hair and generally reduces volume rather than enhancing it. Cutting can also affect volume, but it is not a styling technique in itself; instead, it alters the hair's structure and weight. Blow-drying stands out as the most effective and immediate method for creating volume in a hairstyle.
