The swimming and green hair connection?

Dear Alice,

I've been swimming a lot this summer and I have noticed a green tint to my blond hair. Is this caused by previous dyeing? Is it possible to remove the green tint? Thanks for your time.

Dear Jenni,

Contrary to popular belief, the greening of hair from wading in swimming pools is not caused by the chlorine in pool water or by hair dye. Your hair turns green from the presence of hard metals (copper, iron, and manganese, in particular) in the pool water. Huh? Think old pennies and the Statue of Liberty. The metals are oxidized by the chlorine and then bond to your hair, causing the greenish hue.

What can be done to prevent this from happening? You can wet your 'do and/or run some conditioner through it, and then put on a tightly fitting swimming cap so that there's less of a chance for pool water to contact or be absorbed by your hair. People who maintain pools also need to monitor the level of hard metals in the water so that they can add chemicals that'll neutralize or remove the metals before they oxidize.

What if you already have seaweed tinted locks? You don't have to wait in vain until the tinge grows out. Buy shampoo that's specially formulated for swimmers and contains either chelating (metal removing) agents, such as ethylenediamene tetracetic acid (that's EDTA for those of you not fluent in chemistry), erythorbic acid, and possibly acetylsalicylic acid (also known as aspirin), or antioxidants, such as vitamins A and B. Too much swimmer's shampoo, however, is not recommended, so it's a good idea to quit when you get your original color back, or as close to it as possible.

Dear Alice, In regards to The Swimming and Green Hair Connection?... my hair turned a really obvious lime green after swimming in a friend's pool just once this summer. It wasn't just a tinge of green, it was really bad. I tried the expensive salon shampoos that contained the EDTA, but found the results disappointing. I even tried using Palmolive Dish soap (another Internet suggestion). My wonderful hairdresser did an experiment on me soaking one half of my hair in coke and the other side in lemon juice (similar to putting a penny in either solution in order to get the rust and dirt off). Both worked much quicker (within minutes versus days) and had awesome results compared to the shampoo. But overall, the lemon juice scored the highest points for removing all of the green and getting me back to natural the fastest. So if anyone else gets stuck, save your money and use what you have around the house! Good luck!
