French twist
Hair swept to the back, twisted upwards into a vertical roll and pinned along its length.
Also: French pleat, banana roll
A French twist, or French pleat in Britain, is made by gathering the hair at the back of the head, twisting it upwards into a vertical roll that sits against the head, and tucking the ends inside. It is held by pins along the seam. It gives a smooth, elegant shape at the back of the head and was a favourite of the 1950s and 1960s, worn by film stars and in offices. It needs hair at least below the shoulders.
