These are the muscles that make your hair stand up.... goose bumps, anyone?
You have a muscle at the bottom of a hair strand. Your hair itself has no muscles.
Hair on your arms can stand up when you experience emotions like fear or excitement due to a survival instinct called piloerection. Tiny muscles at the base of each hair follicle contract, causing the hair to stand up and create insulation or make you appear larger to potential threats.

When you are cold, the body's natural response is to generate heat by activating muscles to make hair follicles stand up, causing "goosebumps." This reaction is a vestigial reflex from our ancestors when they had thicker body hair, providing insulation against the cold.
The function of the arrector pili muscles is to contract and make the hair follicles stand upright, causing the appearance of "goosebumps." This response is often triggered by cold temperatures, fear, or emotional arousal as a primitive reflex to help retain body heat or make the individual appear larger or more intimidating.
It causes erection of hair when stimulated by the sympathetic nervous system.
If you are referencing to goosebumps those are actually little muscles that attach to your hair follicle that make it stand up. This process is in response to fear or coldness. In animals their hair stands up to thwart away predators. In humans, it doesn't do that but its the same muscle that pulls the follicle up.
