Re: Why does some people's hair turn green in a swimming pool?

WELL!!! This a difficult question because I have not seen any studies about it around. But I think that the most logical explanation is that the chlorine has an oxidant effect. Maybe it does some reversible oxidation to the pigment in the hairs, and the difference depends on the quantity of the specific pigment that each person has. Another way could be the reaction of the clorine with the disulfide (S-S) bonds of the hairs, although that is also an oxidation reaction!!!
