Cells of the stratum corneum contain a dense network of keratin, a protein that helps keep the skin hydrated by preventing water evaporation. These cells can also absorb water, further aiding in hydration. In addition, this layer is responsible for the "spring back" or stretchy properties of skin. A weak glutenous protein bond pulls the skin back to its natural shape.

Hair and skin are made up of keratin which is basically proteins that are waterproof (which is why your hair and nails are waterproof) and they are basically dead cells.
