Vintage Shingle Bob Hairstyle

The rest of the hair could be styled straight or curled and waved as desired. One of the common techniques was creating pin curls at the sides of the face. The hair was arranged in flat curls and pinned in place until the setting lotion dried.
Another technique for styling involved creating finger-waves. A setting lotion was applied to the hair, and the hair was arranged into a series of ridges and curves using the fingers and comb then allowed to dry and softened, creating a soft wavy style.
