keratinous
Like hair composition
Keratinous means composed of or resembling keratin, the fibrous protein that forms hair, nails, feathers, horns, and the outer layer of skin.
The word appears in scientific and medical contexts: keratinous cysts, keratinous tissue.
Rhino horns are keratinous rather than bony.
