A bob is a haircut, usually for women but occasionally for men, in which the hair is cut short, but a weighted area is left to fall between the ears and chin. It was invented in 1909 in Paris by the hairdresser Antoine, who was inspired by "Joan of Arc." After the First World War, it was made popular in the 1920s by flappers. At the time it was considered a sign of a liberated woman. Early film stars associated with the bob included Louise Brooks, Colleen Moore and Zazu Pitts. In Germany, brunette Louise Brooks's haircut was known as "the black helmet," because it resembled a German helmet. In the 1960s, Vidal Sassoon made it popular again, using the shape of the early bob and making it more stylish in a simpler cut. Many different styles and combinations of the bob have evolved since. A popular style is the Elevated bob, bottom-of-the-ear length, A-line cut with short bangs. The term A-line cut means the bottom edge of the bob is higher in back and lower in front. Elevated bob indicates that, in the back, the bottom edge of the one-length part of the hairstyle is higher than the nape hair line. From the back, this gives the appearance of two haircuts in one with tapered, neckline. It means that the hair at the nape hairline is very short and progressively gets longer toward the top of the head. A good quality haircut can change your entire look and attitude.
