Proteins
Skin, blood, hair, and muscles are primarily composed of proteins, which are macromolecules made up of amino acids. Collagen and keratin are specific proteins found in skin and hair, while hemoglobin is a key protein in blood. Additionally, muscle tissue consists of contractile proteins such as actin and myosin. Lipids and carbohydrates also play supportive roles in these tissues.

You have a muscle at the bottom of a hair strand. Your hair itself has no muscles.

Hair is not held in by muscles, but there are muscles that an erect a hair called the "arrector pili muscle".
Proteins are macromolecules made of amino acids. Amino acids are linked together in a specific sequence to form proteins, which are essential for many biological functions in the body. The order of amino acids in a protein determines its structure and function.
The four major macromolecules are: lipids, carbohydrates, nucleic acids and proteins. Lipids: Ear Wax Carbohydrates: Glucose, Sucrose, Lactose Nucleic Acids: DNA and RNA Proteins: Everywhere! Muscles, skin, and hair. :)
