If hair is used for insulation, why do desert animals like camels have hair?

Keep in mind that “insulation” works both ways -- “insulating” body heat from escaping from a warm body to colder surroundings (hence the fur coat of a polar bear). Compare this with the function of hair on a camel. The hair (fur) limits the absorption of heat by the animal from its hot surroundings.

Principally to protect them from the burning rays of the sun; and to help with water retention.

Desert hair, when in sufficient quantities, can protect from biting insects although sometimes it provides refuge to insect vermin, provides coloration for various social purposes and provides warmth during cold desert nights.
