yes, just the same as a rhino's horn is
Fingernails and hair are dead skin cells that have undergone Keratinization. Keratin that has solidified essentially. Keratin is made up of a family of proteins.
they are modifications of the epidermis layer, which is avascular, pretty much meaning yes it is dead
Fingernails are made of a protein called keratin, and they grow from the base of the nail bed. They protect the fingertips and help with grasping objects. Healthy nails are smooth, uniform in color, and strong.
Fingernails are made of a special kind of protein called keratin, the same kind of stuff that a cow's hoofs and horns are made of. There are many different kinds of proteins. You need the protein of meat or milk or plant seeds in your diet. But don't chew your fingernails. You can't digest the keratin protein. Keratin is made of dead cells, so is your hair and your first layer of skin! It sounds gross, but I wouldn't change it, though!
Although fingernails are made of a protein called keratin which contains carbon, they are not significant carbon sinks. The amount of carbon stored in fingernails is relatively small compared to other carbon sinks in nature such as forests or oceans.
Keratin
Alpha-Keratin
Rhinoceros horns are made out of solid keratin. Keratin is the same material that fingernails and hair are made of. Also like fingernails, the horn can grow back if it is cut.
Fingernails are made of a protein called keratin. Keratin is a tough protein that also makes up hair and the outer layer of skin. As new cells grow at the base of the nail, older cells harden and are pushed out to form the visible part of the nail.
Fingernails and hair are dead skin cells that have undergone Keratinization. Keratin that has solidified essentially. Keratin is made up of a family of proteins.
The same substance as our fingernails - keratin.
Rhinos do not have tusks, but their horns are made from compacted hair and keratin (the same material as fingernails).

Hair and fingernails are made up of a type protein called keratin. This structural element is also a part of the make up of the outer layer of human skin.
Fingernails and toenails are made of the same thing as hair, keratin. Fingernails are found on human beings and various primates. Similar to fingernails in other animals are horse hooves and rhinoceros horns.
The composition of fingernails is a tough protein called keratin. Toenails are also made of keratin. The structure of a nail is the nail plate, the nail matrix and the nail bed.
Human hair and fingernails are made out of keratin. Human teeth are made out of enamel which is considerably stronger than keratin.
