Establishing appropriate proportions to create symmetry in a hair design is known as balance. In hairstyling, balance refers to the harmonious arrangement of elements, such as the length, volume, and texture of the hair, which are tailored to achieve a visually pleasing and symmetrical appearance. This is crucial, as balance can accentuate the features of an individual and enhance the overall look.

The concept of balance is essential in various artistic fields, including hair design, as it helps achieve stability and proportionality. For instance, using symmetry can provide a sense of order and sophistication in a hairstyle, which is particularly important for formal looks. By focusing on balance, stylists can create hair designs that complement the client's facial features and personal style.

Other options, while related to hair design, do not specifically refer to the establishment of proportions or symmetry. Volume pertains to the thickness and fullness of the hair, asymmetrical refers to a lack of symmetry, and silhouette describes the overall form or outline of a hairstyle. However, none of these terms encapsulate the idea of achieving symmetry through proportion as effectively as balance does.
