Summary

A previously described electron histochemical method for detecting cystine in fully keratinised human hair has been modified for the examination of this amino acid residue amongst the cellular components of anagen guinea pig hair follicles. Using the technique the progressive incorporation of cystine into the hair cuticle and cortex has been observed. Although cystine was absent from the hair medulla and outer root sheath cells at all stages of development, a narrow layer of cystine-containing material was found adjacent to the cell membranes of hardened inner root sheath cells.
