Hair colour is decided by the varying amounts of pigments contained in

       the hair structure.  Pigments are contained in two types of melanin

       Eumelanin contains the dark blue through to violet pigments only.

       (Please see Fig. 13)



       Phaeomelanin contains red through to orange and yellow through to green

       pigments. Melanin is found in the cortex and the matrix cement but not in
       the cuticle cells which are completely three of melanin.




       Cuticle cells work the same as prisms absorbing white light and splitting
       it into individual colour wavelengths and reflecting the corresponding

       wavelengths to the pigments.
