Monotreme hair structure and protein distribution are similar to other mammals, but their inner root sheath cornifies differently, suggesting a unique evolution from reptile skin.

Modified keratin binds better to hair, especially bleached hair.

Keratin 33A is a key protein in goat winter coats, especially in high-producing breeds.

The skin has multiple layers and cells, serves as a protective barrier, helps regulate temperature, enables sensation, affects appearance, and is involved in vitamin D synthesis.

Hard skin features like scales, feathers, and hair evolved through specific protein changes in different animal groups.

Human hair is made up of different keratins, some strong and some weak, with specific types appearing at various stages of hair growth.

KRT85 gene variations can help improve wool traits in sheep through selective breeding.

AP collagen peptides improve hair elasticity and gloss.
