Hair length is measured (in centimeters or inches) from the line of the scalp on the forehead up over the highest point of the skull to the end of the hair. This method is not suitable for measuring hair length for people with a fringe. In cosmetology, hair lengths are usually described by the part of the body where the longest hair ends: "chin level", "shoulder length", "mid-back level", "waist length", "hip-length", "classic length" (extends to almost upper thigh-length, where the legs meet the buttocks), "thigh-length", "knee-length" and "ankle/floor length" hair.
