To lighten hair, simply soak clean and dry locks in a low-concentration solution of hydrogen peroxide for about a half an hour. Make sure to carefully rinse out the chemical and not to leave it in for too long to avoid bleaching hair too light.
- Prepare your hair for lightening
Wash your hair with your normal shampoo and conditioner. Even if you do not normally condition your hair, you should still do so prior to bleaching with hydrogen peroxide, as this dries out your locks. Allow hair to air dry after washing.
- Prepare a spray bottle with hydrogen peroxide
For best results, use a low-concentration solution of hydrogen peroxide to avoid hair loss and other damage. Look for a 3 percent solution at the drugstore, or dilute it by mixing a blend of half hydrogen peroxide and half water. To bleach all of your hair, pour this solution into a clean spray bottle. You also need a towel and something to use to pin back your hair, as well as an old T-shirt to wear.
- Spray your hair with the hydrogen peroxide solution
Clip the top layers of your hair out of the way to ensure an even distribution of hydrogen peroxide. Spray the loose lower layers of hair with the solution. Let the top layers down and spray them thoroughly. Be sure to wet all of your hair with the bleach. Leave the solution on your hair for a half an hour.
- Rinse out the bleach solution
Rinse the bleach solution from your hair using cold water. You can also recondition your hair at this stage to make it shinier. Allow your hair to air dry. If it is not as light as you want once it has dried, you can repeat this treatment the next day.
