No, it is not true that melanin is the most abundant protein in dead epidermal structures like hair and nails. The primary protein present in these structures is keratin, which provides strength and resilience. Melanin, on the other hand, is a pigment responsible for color and is found in the living cells of the skin, hair, and eyes, but not in significant amounts in the dead structures themselves.
keratin
The most abundant protein in dead epidermal structures is called keratin. It is a fibrous protein that forms the main structural constituent of hair, feathers, hoofs, claws and horns.
It is called Keratinocyte, which is in the outermost layer of the epidermis.

I screwed up-- the first person had it right. Here's their answer: "A protein is composed of several amino acids chained together - so no melanin is not a protein. Melanin is formed from the amino acid Tyrosine and is NOT a chain of amino acids thus it is not a protein nor is it a amino acid."
The water insoluble protein accounts for the bulk of the epidermal thickness thickness.
Epidermal keratinocytes are cells that accumulate protein in the epidermis. These cells produce and store keratin, a durable protein that helps form the structure of the skin and protect it from damage. Keratinocytes are the most abundant cells in the epidermis and play a crucial role in maintaining skin integrity.
The eye color gene encodes for a protein called OCA2 (P gene), which helps determine the amount of melanin produced in the iris. Melanin is responsible for the color of the eyes, with more melanin resulting in darker eye color.

Keratin
The protein in epidermal cells that makes the skin relatively waterproof is called keratin. Keratin is a strong protein that forms a barrier to prevent water loss and protect against environmental damage.
