The forelock or foretop is a part of a horse's mane, that grows from the animal's poll and falls forward between the ears and onto the forehead. Some breeds, particularly pony breeds, have a naturally thick forelock, while other breeds, such as many Thoroughbreds, have a thinner forelock. Primitive wild equines such as the Przewalski's horse with a naturally short, upright mane generally have no hair falling forward onto the forehead. Other equidae such as donkeys and zebras, have no discernible forelock at all.
