What Cancels Out Green Hair Color?
There are a few ways to cancel out green hair color, depending on the cause. If the green tint is the result of chlorine or other minerals from a swimming pool, a clarifying shampoo or a mixture of baking soda and water can help remove the green. If the green is the result of dyeing the hair with a cool-toned color, a warm-toned color such as red or orange can be used to cancel out the green. Bleaching and toning may also be needed for more severe cases.
