What Will Happen to My Hair If I Put Peroxide on It?

Hair can be dyed with peroxide. Hair dyes contain hydrogen peroxide as an active ingredient. Using peroxide to dye the hair should make it two shades lighter than the natural hair color.

It is best to dye hair slowly. Hair will react differently. If the desired hair color is to the person's liking, mix peroxide and water in a small spray bottle. Spritz the hair a few times every morning. This will gradually lighten the hair. Mix a half cup of peroxide with a half cup of conditioner for a faster dye job. After dyeing the hair with peroxide, it is important to keep the hair hydrated. Limit using shampoo and exposure to heat.
