A bob haircut is a short to medium length haircut, the hair is being cut straight around the head (sometimes layered or softened) sometimes accompanied by a fringe.
A polish hairdresser, Antoni Cierplikowski, became the world’s first celebrity hairdresser in 1909. He started a fashion haircut which was short and inspired by Joan Of Arc. Way back then woman wore their hair long, so this new short bob haircut was very fashionable and somewhat outspoken, and even called rebellious.
Back in the twenty-first century, short hair on a female is celebrated and executed beautifully, whether it is short and textured, full of volume or straight and sleek.
