To tie hair into a knot or bun style, first brush through the hair to remove any snarls and tangles. Gather the hair up in one hand, and arrange it into a ponytail, securing it with an elastic hair tie. As an alternative, Cosmopolitan suggests leaving some space for the natural texture of the hair to show instead of pulling the hair into a tight ponytail.
Twist the hair, and then twirl it around itself to create a knot. Secure it with bobby pins. For some knot styles and hair textures, a hair tie is not even needed. To smooth the hair knot and tame any fly-away strands, Cosmopolitan suggests spraying a boar bristle brush with a bit of shine serum and using it to gently smooth the hair.
To create a breezy casual look, rake the fingers through the hair several times, and then wrap an elastic tie around the hair a few times without pulling the hair all of the way through the elastic. This styling creates a bun-like look on top or at the back of the head. To accentuate a casual look, Cosmopolitan suggests leaving a few strands of hair loose at the sides and nape of the neck.
