Just wanted to share a little truth on hair turning green in pools. There have been a lot of posts on this subject but want all of you to know that it is not the chlorine that turns your hair green. It's a high content of copper due to piping they use for heaters. Chlorine is like bleach to keep pools clean. For example: if you wear copper jewelry, your skin in that area turns greens. Same thing with your hair. Just some knowledge to pass on . Hope this helps anyone out!
