Hair follicle nerve endings respond to pain and touch.
Hair follicle receptors
Hair follicle nerve endings respond to external stimuli by detecting changes in temperature, pressure, and movement. When stimulated, these nerve endings send signals to the brain, which interprets the sensation as touch, pain, or other sensory information.
Hair is to protect our bodies from the elements, helps regulate heat and is a sensory item this is why each hair follicle has nerve endings attached. Its also there to look pretty! Pubic hair is also there to stop skin from rubbing.
The sensory nerve endings are specialized neurones that are stimulated to fire action potntiels based on chemical factors, photons, heat etc depending on their location and type.

At the end of a nerve, there is a synapse, which transfers the signal on to the next nerve until it reaches it's destination - ie. the brain or a muscle. Nerve endings are what we feel the world around us with. Nerve endings are in every part of your body and they are always sensing what is going on around you. They feel the chair against your bottom, the key board under your finger tips, etc.

The three types of unencapsulated tactile receptors are free nerve endings, root hair plexuses, and tactile discs. Free nerve endings are found throughout the skin and detect pain and temperature. Root hair plexuses are located around hair follicles and detect hair movement. Tactile discs are found in the deeper layers of the skin and detect light touch and pressure.
All animals have nerve endings.
