Hair is primarily made of a special type of protein called "keratin." Keratin is the same tough, water insoluble material that fingernails and animal horns and hooves are made of. Hair also contains natural oils (lipids) and water. These hair "ingredients" are arranged in 3 primary structures: the cuticle (which is the outermost, shingle-like layer); the cortex (the inside of the hair consisting of bundles of protein filaments; and the medula (a soft spongy-like core in the center of the cortex.)

How many genes does hair have?
Human hair does not contain genes. Hair is composed of a protein called keratin, which is produced by hair follicles located in the skin. The traits of your hair, such as color, texture, and thickness, are determined by your genetics.
What substances is cellular cytoplasm primarily composed of?
Cellular cytoplasm is primarily composed of water, proteins, salts, and organic molecules such as sugars and lipids. It also contains cell organelles like mitochondria, ribosomes, and the cytoskeleton, which help in various cellular functions.
Fibers of the cytoskeleton are composed of primarily?
Fibers of the cytoskeleton are primarily composed of three types: microfilaments (actin filaments), intermediate filaments, and microtubules. Microfilaments are primarily made of actin, intermediate filaments consist of various proteins like keratins and lamins, while microtubules are made of tubulin protein subunits.
What is a piece of human hair called?
A single strand of human hair is called a "strand" or "hair follicle".
Which is larger a lymphcyte or a human hair?
A human hair is larger than a lymphocyte. Lymphocytes are white blood cells that are much smaller in size compared to human hair.
Is human hair and nails composed of solely keratin?
yes
Is hair a mineral?
No, hair is not a mineral. Minerals are naturally occurring inorganic substances with a specific chemical composition and crystalline structure, while hair is composed primarily of a protein called keratin.
What parts of the human body is composed of protein?
tissues, nails, muscles, cells, blood, hair.....
Which parts of your body is made up of primarily protein?
Bones and teeth are not primarily protein.
Which human body part or plant part is not completely composed of cells?
For human bodies: the hair, nails and outer skin have no cells.
Which human organ system is mainly made up of glands and hormones?
The endocrine system is primarily composed of glands and hormones.
Planet composed primarily of iron oxide?
The is no known planet composed primarily of Iron Oxide.
Does hair contain nitrogen?
No, hair does not contain nitrogen. Hair is primarily composed of keratin, a protein made up of carbon, hydrogen, oxygen, and sulfur. Nitrogen is not a significant component of hair.
Air is composed primarily of what 2 gasses?
Air is primarily composed of nitrogen (about 78%) and oxygen (about 21%).
Human skin is primarily what type of Epithelium?
Human skin is primarily composed of stratified squamous epithelium. This type of epithelium consists of multiple layers of flat cells that provide protection and help prevent water loss.
What substance is hair composed of?
Hair is primarily made up of a protein called keratin, which is also found in the outer layer of the skin and in nails. Other components of hair include water, lipids, pigments, and trace minerals.
Which two rocks are primarily composed of a mineral that bubbles with acid?
Limestone and dolomite are two rocks that are primarily composed of the mineral calcite, which bubbles with acid.
