A hair pin up, often called an updo or hair up, is a styling service where your hair is dressed and secured away from the face and neck, usually for a wedding, prom, party or other special occasion. Working with your natural length and texture, a stylist might use sectioning, curling, backcombing, plaiting, twisting and pinning to create anything from a soft, relaxed look to a sleek, structured style. Grips, kirby pins, U-pins and a little hairspray hold everything in place, and accessories such as slides, combs or a veil can be worked in.
