Measurements have been made of the nuclear magnetic relaxation times T 1 and T 2 of the protons of water in hair. These are interpreted as showing that water molecules in hair exist in a continuous range of environments with a wide spread of rates of molecular rotation. Even at high water contents most of the water molecules are much less mobile than molecules in bulk water. The term “mobility” is given a quantitative meaning.
