I understand that normal shampoos are all alkaline, which causes the copper to precipitate out of my slightly-acidic tap water and into my bloody hair!
I've tried Boots' "Sun, Swim and Gym", hair products, but the water still turns green - as does my hair.
Does anyone have any recommendations or am I really going to have to spend at least a night a week with lemon juice or tomato ketchup on my hair?
Thank you
