Trendsetters, beware; this stylish hairdo has a darker side. When hair is tightly pulled back, the force on your follicles can lead to traction alopecia, which means you are gradually losing hair from the constant pull on your hairline. This strain can even cause scarring, so take care to loosen up the bun (or any tight hairstyle) before you head out the door.
