The term 'bobs' is a type of hairstyle and weaving technique. It is a short haircut that is cut straight around the head, usually at the jawline or just below the ears. The hair is then parted in the middle and combed down, with the ends of the hair being curled or waved. This style was popularized in the 1920s and has been a classic look ever since. Weaves are a type of hair extension that is used to add length and volume to the hair. They are typically made from synthetic or human hair and are attached to the scalp using clips, glue, or sewing. Weaves can be used to create a variety of looks, from long and flowing to short and curly.
