Are nails made of keratin or collagen?
Your nails are made of keratin
Keratin is a type of protein that forms the cells that make up the tissue in nails and other parts of your body. Keratin plays an important role in nail health. It protects nails from damage by making them strong and resilient.
Are nails and hair are both composed of keratin?
Keratin is the key component of our skin, hair and nails. Its protein building blocks have amino acid chains, coiled, cross-linked and classified as either hard or soft. It separates us from our environment by forming thin and flexible skin, strong hair and rigid nails. Even embryonic teeth have a keratin layer!

Fingernails and toenails are made of a tough protective protein called alpha-keratin, which is a polymer. Alpha-keratin is found in the hooves, claws and horns of vertebrates.
How is collagen?
Collagen is a hard, insoluble, and fibrous protein that makes up one-third of the protein in the human body. In most collagens, the molecules are packed together to form long, thin fibrils. These act as supporting structures and anchor cells to each other. They give the skin strength and elasticity.

Although if the environment, microbial life and internment methods favor decomposition, it will be relatively quick.
