Eyebrow shapes can significantly influence facial features and expressions. Common shapes include arched, straight, rounded, and s-shaped. Each shape can enhance different aspects of the face, such as the eyes and cheekbones, and can be tailored to suit individual preferences and face shapes. The choice of eyebrow shape often depends on personal style and trends. For instance, arched eyebrows can create a more dramatic look, while straight eyebrows tend to offer a softer appearance. Maintaining the desired shape typically involves regular grooming, such as plucking or waxing, to keep them looking neat and defined.
