Hair cells
papillary layer
Mainly dead epithelial cells consisting almost entirely of the protein Keratin.
Keratin
the top layer; the epidermis
I think so
keratin
Keratin is formed by the outer layer of the skin. The epidermis, which is on top of the dermis, as a part of layer called the basal layer. This is the growing layer, which pushes out when a new layer forms. As soon as the layer comes closer to the surface it becomes filled with the product called keratin. This layer cells is dead because it cannot be supported this close to the surface. Hair and nails also are formed of keratin and are also formed in the same way. Keratin is made of fibrous polyproteins and so is composed of nitrogen, carbon, hydrogen and oxygen.

This is found in the stratum corneum (horny layer), the most most superficial layer which are dead cells filled with keratin. They form a waterproof barrier and make it tough.
The outer most layer of the skin is called epidermis.Many of the cells of epidermis produce protein called keratin. The new epidermal cells are formed at the base of the skin and hence the older cells are pushed to surface. The surface cells protect the inner new cells.Gradually the surface cells get filled with keratin. This process is called kertinization.During this process the epidermes gets dividd into five distinct regions.Top most layer is stratum corneum. It consists of more than 20 layers of dead cells. These cells get filled with keratin. These cells are said to be cornified. The cornified cells are surrounded by a hard protective envelope,which makes the skin waterproofing....more over there are other layers of epidermis which has its independent function.
