title: [Green hair: clinical, chemical and epidemiologic study. Apropos of a case].
abstract: A 36-year-old blond woman suddenly developed green tinted hair following exposure to swimming pool water. This was the first green discoloration she noticed, although she had been an active swimmer for several years. Clinical examination showed green tinting toward the distal ends of the most superficial strands of hair. The copper content of plucked green hair measured by atomic absorption was elevated to 3,900 ppm and the copper concentration in water from the swimming pool implicated was 9.94 ppm. Following renewal, the latter value decreased to 107 ppb. Hair examination under polarizing light was normal, and a scanning electronmicroscopic study of hair samples showed a total loss of cuticle with micropits scattered over the hair shaft surface mimicking a "dead tree trunk". Epidemiological investigations showed that the increased copper content of swimming pool water was due to added algaecides without adequate replacement of the water. Hair damage resulting from repeated waving and/or bleaching of the hair turns out to be an important factor in the deposition of copper by inducing an increase in keratin content of cysteic acid and related anionic sulfonate groups which participate in copper adsorption. On the ocassion of this case-report, epidemiological data published by others, together with the chemical and therapeutic aspects of green hair are reviewed.
