Crop (hairstyle)
（重定向自Eton crop）
A crop is a short hairstyle worn with the hair cut very close to the head. It is frequently sported by both men and women, though the style is usually only named as a crop when sported by a woman. Men entering the armed forces in many countries have their hair cropped during Recruit Training. In the Western world, cropping the head of a prisoner was traditionally a symbol of their subjugation and a deterrent to escape.
