Compositions of human normal hair and nail low‐sulfur proteins were compared using two‐dimensional electrophoresis of their S‐carboxymethylated (SCM) derivatives. Six SCM low‐sulfur protein components with molecular weights (MWs) of 76,000, 73,000, 72,000, 64,000, 61,000 and 55,000 were common to the hair and nail. One component with a MW of 61,000 was specific to hair, and two components, both with a MW of 50,000, were specific to nail.
