Keratin is the hard protein in the epidermis that forms hair and nails. What is it called?

Explanation:
The main idea is recognizing keratin as the hard protein that makes hair and nails. Keratin is a fibrous, insoluble protein that forms the tough, protective keratin found in hair and nails, giving them their strength. Elastin provides elasticity in tissues, collagen is the primary structural protein in connective tissue, and melanin is the pigment that determines color. So the name that specifically describes the hard protein of hair and nails is keratin.
