Eyebrow extension is a cosmetic procedure in which individual synthetic or natural hairs are attached to the existing eyebrows to create a fuller and more defined look. It is similar to eyelash extensions, but specifically focuses on enhancing the appearance of the eyebrows. The extensions are typically applied using a special adhesive and can last for several weeks before requiring touch-ups or removal. Eyebrow extensions can be a solution for individuals with sparse or thin eyebrows, or those who want to achieve a more dramatic eyebrow shape.
