You may be able to find powdered vitamin C for sale at your local pharmacy. To use the powder, just work with 1/4 teaspoon (1 g).

1 large squirt of shampoo is about the size of a quarter. If you have long hair and want to use more shampoo mixture, double the amount of shampoo and vitamin C powder.

Take the time to really work the mixture through all of your hair, especially if it’s long.

Set a timer and do something fun while you wait. Just don’t forget that you have the mixture on your hair!

Since this is a pretty gentle method, repeat it if you want to remove more dye.

1 bottle is an activator and the other bottle is the remover. These work together to shrink the molecules of hair color so you can easily wash the color away. Don’t run out of product if you have long hair! Buy a few boxes if your hair goes past your shoulders.

Color removers are notoriously stinky, so open a few windows to ventilate your space.

Stir for at least 30 seconds so the solution is thoroughly combined.

If you can, stay in a warm room while your hair processes. The heat opens your hair cuticles so more of the color comes out.

Since you want to be thorough, you’ll probably need to shower for 30 to 45 minutes. Shampoo work as a surfactant that helps clean the hair, use a shampoo that is more gentle and isn’t as harsh on your hair.

For example, if you mix 2 tablespoons of powder, add 2 tablespoons (30 ml) of developer. Reach for a non-metallic bowl to mix the developer solution. A plastic bowl is great since it won’t react to the chemicals in the solution. You can use a higher volume developer which has more peroxide, but it’s more damaging to your hair.

If you want to make more bleach bath for your long hair, feel free to double the amounts.

Try to work quickly so the solution evenly strips the pink dye from your hair.

If you used a high volume developer, you probably don’t need to leave it on for more than 15 minutes since it works so quickly. If you used a low volume developer, you can usually leave the bleach bath on for up to 30 minutes.

If you’re getting rid of the pink dye so you can dye your hair a different color, you don’t worry about conditioning your hair. Conditioner could actually prevent the new hair color from processing the right way.
