One of the key differences between hair and fur lies in its overall uses and purposes. Hair is primarily used for fashionable purposes,while fur is a necessary tool for insulation.

Another key difference between hair vs fur is its overall texture. While both hair and fur can be soft and smooth to the touch, the overall density and textural makeup of hair and fur differ quite a bit from one another.

Hair (and a coat of hairs, called fur or pelage) is uniquely mammalian. No other creature possesses true hair, and at least some hair is found on all mammals at some time during their lives. Hairs grow out of pits in the skin called follicles.
Hair and fur are chemically indistinguishable, having the same chemical composition, and are made of keratin. The primary difference between hair and fur is the word usage. The hair of non-human mammals refers as “fur,” while humans are said to have hair. So, basically, hair is a characteristic of all mammals.
