Fur and hair are both types of mammalian coverings, but there are some key differences between the two. Fur is typically longer, thicker, and more dense than hair, and it is designed to provide insulation against the cold. Hair, on the other hand, is shorter, thinner, and less dense, and it is primarily used for protection against the sun and other elements.
Another key difference between fur and hair is that fur is usually shed seasonally, while hair is not. This is because fur is designed to keep animals warm during the winter months, and it is not needed during the warmer months. Hair, on the other hand, is not as important for insulation, so it is not shed seasonally.
