Step-by-step explanation:
The student is referring to the dent in the middle of the hair, which is commonly known as a hair parting. A hair parting is a styling technique where the hair is divided into two sections, with one section falling on each side of the part. It is a simple yet versatile way to change the hairstyle and create different looks. Hair can be parted down the middle or to one side, depending on personal preference and the desired style.
For example, if a person has long hair, they can part it down the middle and let the hair hang down on both sides. This creates a symmetrical and balanced look. If someone wants to create a more voluminous look, they can part their hair to one side, which adds volume and texture to one side of the hair.
