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.

Water is an inorganic compound, since it does not contain carbon. This does not mean that it is not necessary to life: The terms "organic" and "inorganic" in chemistry have remained unchanged from an earlier period when the chemistry underpinning life was poorly understood, but the definitions of these terms have changed so that a compound must contain carbon to be considered "organic" in the chemical sense.
Skin and hair are both biological amides (carbon, oxygen, nitrogen based compound) which causes them to be remarkably inert (unlikely to react with chemicals), however, the pigmentation in skin is not so inert, hence why skin color can change from contact with chemical compounds.
It changes color.

Since being on oxygen therapy 15 hours a day, I have twice had my hair permed, and it's just a mess, no real curls or waves, and my hair just looks awful. Does oxygen affect my hair?
