Hair dye can permanently, semi-permanently or temporarily alter the natural hue of an individual's hair color. Some individuals may dye their hair, only to discover that they do not like the new color. Learn how to remove hair dye with a peroxide developer to naturally bleach out a bad hair dye job.

Prepare for the peroxide developer application. Avoid washing your hair 24 hours before planning to remove the hair dye. Also avoid applying conditioners or hair products such as gels or hairspray. Such products may interfere with the chemical reactions in the peroxide, reducing the efficacy of removing the hair dye.

Mix the hydrogen peroxide developer with powder hair bleach until the resulting paste is smooth and not lumpy. Use a plastic dish and plastic mixing utensil that you do not plan to use again after mixing the developer. Avoid using anything metal, as it may cause a negative chemical reaction in the peroxide developer.

Rub a thin layer of petroleum jelly (like Vaseline or similar products) onto the skin edging the hairline. Then, put on the gloves. The developer solution can burn bare skin.

Apply the peroxide developer and bleach mix to the hair strands from which you wish to remove hair dye. Wait for 15 to 60 minutes. The amount of removal will depend on the level of the developer (such as Levels 10, 20, 30, or 40). The higher the level, the faster the developer will work. The solution will slowly bleach and strip color from the hair strands.

Rinse the hair thoroughly in warm water. Apply a conditioner; rinse again. Observe the results in a mirror. Wait 24 hours before re-applying more developer if you wish to lighten the hair color again--or if you notice areas of the hair that you missed.
