Hair length
How long hair is worn, from shaved through short and medium to long and floor-length.
Also: length scale
Hair length is usually described against the body: shaved; very short or cropped; short, ending between the ears and jaw; medium, from jaw to shoulders; long, from shoulders to mid-back; and very long, to the waist or beyond. On curly hair the visible length may be far less than the stretched length because of shrinkage. Head hair grows about 1 centimetre a month on average, so growing from a bob to mid-back can take several years.
