Summary An artificial hair-waving which is popular among Japanese women and the use of thiol-containing solutions for reforming hair-wavings was tested for its effects on hair mercury values. The first step of the procedures, shampooing and drying, entailed slightly organic mercury concentrations; the second step, applying the cosmetic containing thiols, reduced organic mercury concentrations to less than half of the original value. After completion of all 5 steps, the organic mercury concentration decreased to one third of the original value and the inorganic mercury concentration decreased only slightly. Next, the cosmetic containing thiols and the solution of cysteine HCl or sodium thioglycolate were compared with each other for the hair mercury diminishing effect. At an equimolar basis of thiols (0.65M), the cosmetic had the largest effect for reducing organic mercury concentrations at all the PH conditions tested (below 1, 4.0, 6.35 and 9.4). Inorganic mercury concentrations were reduced only by cysteine HCl solutions of 1 or 2 M.
