We had excellent luck with the Ion swimmers shampoo& conditioner, also from Sally's beauty supply, to fix my daughter's green hair. Just thought I'd throw that in there.
Good luck with fixing the green hair!
I finally purchased a copper test and the result is .15 ppm. I did the jacks filter fiber and the pink stuff according to directions. We are still getting green hair. Is this considered high copper? Does anyone know if walmart sells a good sequestrant to rid my pool of copper. No one near me sells jacks so the shipping cost is very expensive.
