What about hair and nails?
Hair and nails are made from a protein known as keratin. Hair grows from a tiny opening withinside the pores and skin referred to as a follicle. Nails develop from the nail root, that's hidden below the pores and skin at the bottom of the nail. We have nails on our hands and feet even earlier than we're born. Under the nails are blood vessels that keep the nails pink. Nails are tough and they save you the gentle pores and skin at the pointers of our hands and ft from getting hurt.
