Recreate the effortless oversize bun worn by TV personality Lauren Conrad, pictured here, in seconds. First, apply smoothing cream throughout hair and pull it into a high ponytail. "Once fastened, spray the ponytail generously with light to medium hair spray," says Joey Oso, a New York-based L'Oreal Professionnel hairstylist who styles hair for high-end photo shoots, fashion shows and television. Create volume by blow-drying the ponytail for 10 seconds before lightly brushing it out again, making sure to not remove volume. "Wrap the ponytail onto itself, around the hair tie, and bobby pin it into place."
