Abstract
Optical low-coherence reflectometry is used to investigate the interna l structure and optical properties of human scalp hair. Regardless of hair color, the refractive index of the cortical region remains within the range of 1.56-1.59. The amplitude of the backscattered infrared l ight coupled into different-colored hair confirms the relative melanin content. Discontinuities in the refractive index permit identificatio n of distinct structural layers within the hair shaft.
