How To Get The Green Out Of Hair
Q: After I permed my hair the gray turned green. How can I change my hair color to brown.
A: Sometimes using chemicals in the hair strips color and causes the hair to come out with certain tints depending on what you used and the particular chemistry of your own hair.
I'd suggest you use a special clarifying shampoo and conditioner in your hair for a while to get the excess chemicals out of your hair. After that you can use a rinse over the entire hair based on the color you're looking for in the final look.
Be sure to test the color on a section of your hair before you do the whole thing.
