Green Tint
Q: Hello, my daughter's hair has a green tint to it. What do you suggest that we can do to get this green color from her hair? Yes, she swims. She is on a swim team.A: This is a common problem, especially if the hair is lightened, or sun-bleached.
You can also visit your local beauty supply store to find specially formulated swimmers' shampoo and conditioner to help keep the hair healthy and the color true during swim season. These shampoos are designed to counter greening and protect the hair from the chemicals that cause it.
In some severe cases, when the hair won't respond to these shampoos and conditioners, you may want to consider a mild tinting service. Using a very light shade of a red based hair color as a deposit-only formula (mixing one ounce of pale red-based hair color with one ounce of 10-volume peroxide developer and two ounces of conditioner) you can perform a corrective tint to counteract the green color.
