Half-up, half-down
A style in which the top half of the hair is tied back or pinned and the rest hangs loose.
Also: half up
A half-up, half-down style takes the upper section of hair, from the temples to the crown, and ties, twists, braids or pins it back, while the lower hair hangs loose. It keeps hair off the face while showing length and is a common bridal and party look, often with curls in the loose hair. A half-up bun or half topknot is a quick everyday version. Waterfall braids and pinned twists are fancier ones.
