Final answer:
It is true that eyebrows should be properly tweezed in the direction of hair growth to prevent irritation and maintain a natural look. Eyebrow maintenance includes tweezing, as well as using eyebrow pencils, powders, and gels for defining and filling in the brows.
Step-by-step explanation:
The question pertains to the proper technique for tweezing eyebrows, which is part of a beauty routine. It is indeed true that eyebrows should be tweezed in the direction of hair growth to avoid irritation and to achieve a more natural appearance. When tweezing, the skin should be held taut and each hair should be pulled out individually in the direction it grows. This helps maintain the natural arch of the eyebrow and prevents the hair from breaking.
Eyebrow maintenance can include various products and techniques to enhance the brow's appearance. Eyebrow pencils, powders, and gels, for example, serve to define the shape, fill in sparse areas, and provide a fuller, more textured look to the eyebrows. Historically, the pursuit of beauty has even led to artificial modification of eyebrows, as seen in ancient Egyptian sculptures which depicted ideal beauty standards.
