Long Hair - Hair Lengths

Hair Lengths

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 its termination. In cosmetology, hair lengths are usually categorized according to the part of the body where the bulk of the longest hair terminates: shin 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.

Hair usually takes about two years to reach shoulder length, and at approximately 80–90 cm (32–36 inches) for most people, waist-length hair usually takes about seven years to grow, including occasional trims.
