My daughter’s hair turned green after a pool party at a friend’s house. Did the chlorine in the pool cause this to happen?
No. Exposure to metals dissolved in the water, particularly copper, iron, and manganese caused your daughter’s hair to turn green. When metals attach to the hair shaft and are oxidized by the chlorine, they can leave behind a green residue. To remove the metals from the hair, use a swimmer’s shampoo that contains the chelating chemical ethylenediamine tetra-acetic acid (EDTA).
