We've been swimming a lot this summer, mostly at Cherry Hill, and Laine's hair was already turning green. She has gorgeous, flaxen blond hair and it soaks up chlorine like a sponge. Laine also loves swimming and is in the pool as long as we're there. We tried a baking soda/shampoo rinse. That didn't do much.
So we pulled out the tomato sauce and soaked her hair in it. Reminded me of when I was little and my mom did the same thing for me. (She also bathed our cat in tomato juice when it got sprayed by a skunk. She's a good mom.) Now Laine's hair isn't green anymore but I'm sure this isn't the last tomato rinse of the summer.
