You will need
1 Spray bottle
1 bottle of hydrogen peroxide (not all is used)
Step 2: Clean the spray bottle
Use water to make sure the spray bottle is safe to use. You can also use dish soap to help clean it out.
Step 3: Hydrogen Peroxide
Put a generous amount of hydrogen peroxide in the spray bottle. When your done, put the cap back on the spray bottle.
Step 4: Apply to hair
Lightly spray it throughout your hair. Be careful not to use too much. I suggest doing this 20-30 minutes before a shower WITHOUT shampoo. You can use conditioner, though. Do this for about a week, then you can return to normal showering.
