Buy vitamin C tablets and a good-quality shampoo, crush the tablets and combine them with the shampoo, apply the mixture to your hair, cover your hair with a plastic cap or bag while the treatment processes, and then wash and condition your hair. Removing hair color with a vitamin C treatment is an easy, healthy way to remove dye from hair, which is less damaging than removing or lightening hair dye with bleach.
- Buy the materials that you do not have
Obtain vitamin C tablets that can be crushed, a good shampoo, something to crush the tablets, a container in which the treatment can be mixed, and a shower cap or plastic bag big enough to cover your scalp.
- Crush the vitamin C tablets
The number of vitamin C tablets you need to crush depends on the length and thickness of your hair. You will likely need to experiment with varying amounts to find the right concentration.
- Combine the crushed vitamin C tablets and some of the shampoo in a clean container
Put the crushed tablets and a generous amount of shampoo in your mixing container. It is better to use more shampoo rather than less to create a good lather. Ensure the mixture is smooth.
- Apply the mixture to wet hair
Apply the vitamin-and-shampoo mixture to wet hair as you would a normal shampoo. Create a thick lather to ensure the mixture reaches all of your hair.
- Cover your hair while you wait
Cover your hair with a shower cap or plastic bag while you let the mixture take effect for about 45 minutes.
- Wash out the mixture and condition your hair
Wash the mixture out of your hair and then condition to ensure your hair does not dry out.
