A bob is a popular hairstyle characterized by hair that is cut straight around the head at about jaw-level, often with bangs at the front. This versatile cut can vary in length, texture, and style, making it suitable for different hair types and face shapes. Bobs can be worn sleek and straight or with waves for a more casual look. 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 more dramatic angle. The bob has been a fashionable choice since the early 20th century and continues to be a timeless option for many.
