Where in the human body is hair not present?

Hair is not present on the palms of the hands. This is due to the unique structure and function of the skin in this area, where the demand for dexterity and sensitivity predominates. The skin on the palms is thick and has a high concentration of nerve endings, enabling a strong tactile response needed for grasping and manipulating objects.

In contrast, other parts of the body, such as the forehead, scalp, and feet, do have hair follicles and can exhibit hair growth. The forehead can have fine vellus hair, while the scalp is densely covered with hair. Feet, though they may have less dense hair growth than other parts of the body, still contain hair follicles, particularly on the tops of the toes and the dorsal side of the feet.

Therefore, the absence of hair on the palms is a distinctive characteristic important for their functional roles.
