Hair styling and color matching with face shape is a field in cosmetology and fashion that focuses on the art of selecting hairstyles and hair colors that complement and enhance a person's facial features. This practice involves understanding the proportions of different face shapes (such as round, oval, square, heart, and diamond) and how to balance or emphasize certain features. It also takes into account the client's skin tone and hair type. Hairstyles and colors that are harmonious with a person's face shape can create a more balanced and aesthetically pleasing appearance.
