I have been battling the green in my daughter's hair and I'm losing. She is a toe head and her hair is neon green when it is wet. When dry, it is lighter green, but very noticeable. At first, it was just a green streak down the back, but now it is all her hair. I took a water sample to three stores and all tests came back with 0 for copper. I do realize that I could have copper but it isn't enough to show up in a pool store test. I have gotten advice from this site to pre-treat her hair and rinse it afterward. We are doing that, to no avail. My hair is darker and I am more careful about saturating it with good water and then washing it after so I am not burdened with the green. However, my hair 'feel's' like her hair. It is crunchy and tacky feeling and smells like pennies, even after washing and conditioning. I am wondering if I need to use a sequestrant. My water is very clear and I do not have any staining in the pool. I noticed the neighbor girl is going green too. Kinda feeling bad about turning the whole neighborhood into green aliens.
If I get the copper out of her hair and sequester the water, will her hair stay blonde?
On a side note, I'm assuming the copper came from the pond when we filled the pool. Pretty sure the neighbor put algaecide in to keep the weeds down. Hadn't even considered it before filling the pool. Ah, hindsight.
