which side of a horse has the most hair
Mane (horse) The mane is the hair that grows from the top of the neck of a horse or other equine, reaching from the poll to the withers, and includes the forelock or foretop. It is thicker and coarser than the rest of the horse's coat, and naturally grows to roughly cover the neck. Heredity plays a role, giving some horses a longer, thicker mane, and others a shorter, thinner one.
Hair follicle The position and distribution of hair follicles changes over the body. For example, the skin of the palms and soles do not have hair follicles whereas skin of the scalp, forearms, legs and genitalia have abundant hair follicles.[1] There are many structures that make up the hair follicle. Anatomically, the triad of hair follicle, sebaceous gland and arrector pili muscle make up the pilosebaceous unit.[1]
