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.
This phenomenon is caused by the piloerector muscles contracting, which can be triggered by fear, cold temperatures, or emotional responses. The muscles pull on the hair follicles, causing the hairs to stand upright. This is known as piloerection, or colloquially as "goosebumps."
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.
A Van de Graaff generator is a machine that can make your hair stand up. It generates static electricity that causes your hair to repel each other due to the same charge, resulting in an "electric" hairstyle.
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.
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.

One theory states that long ago, when men were covered by much more hair than they are today, the erector pili muscles caused the hair to stand up when the body became chilled. The hairs would bunch together and protect the skin from cold, harsh weather.

Protein is the essential nutrient that makes up your skin, hair, nails, muscles, and organs. It plays a key role in the structure and function of these tissues in the body, helping with growth, repair, and maintenance. Eating a diet rich in protein sources like meat, fish, eggs, dairy, legumes, and nuts is important for overall health and well-being.
