A bob hairstyle is a popular haircut characterized by hair that is cut straight around the head at about jaw-level, often with bangs at the front. This style can vary in length, with some bobs falling just above the shoulders, while others may be shorter. Bobs can be worn straight, wavy, or curly, making them versatile for different hair types and personal styles. There are several variations of the bob, including the A-line bob, which is longer in the front and shorter in the back, and the inverted bob, which features a stacked back for added volume. The bob has been a fashionable choice since the early 20th century and continues to be a favorite among many, including celebrities like Victoria Beckham and Katy Perry.
