What effect does sebum have on the horse's coat?

• A. It provides a natural sheen and helps maintain skin and hair health.
• B. It dries the coat and skin.
• C. It makes the coat waterproof in all conditions.
• D. It has no effect on coat appearance.

Answer: (A)

Sebum is the horse’s natural oil produced by the sebaceous glands. It coats the hair shaft and skin, keeping the coat moisturized and the skin healthy. This oil helps the hair lie smoothly, enhances shine, and makes grooming easier because the hairs are conditioned rather than dry and brittle. It also adds a protective barrier that helps reduce moisture loss and supports skin health. While sebum can give some extra moisture resistance to the coat, it does not make the coat waterproof in all conditions. That’s why a balanced, healthy amount of sebum results in a natural, healthy-looking coat with a pleasing sheen.
