What is Keratin?

Keratin is an extremely strong naturally occuring protein that is a major component of things like fingernails, hooves, claw and horn coverings, and hair.

Keratin is present in the outer skin cells (or Keratinocytes) which is why skin is virtually waterproof. These cells will toughen with repetitive rubbing or friction and form protective calluses, for example; on musician's guitar plucking fingers or athlete's raquet holding hands.

Flaky skin or dandruff is simply your body getting rid of these excess cells.
