Bleaching hair at home is far cheaper than visiting a salon, and doesn't necessarily require the use of aluminum foil. For those with dark-toned hair, bleaching is the only way to dye hair lighter without resulting in an orange color. After bleaching, you can choose to add color or leave as it is. Bleaching also has the advantage that hair becomes more porous, allowing hair dye to hold more easily. After bleaching, you must make sure to take care of your hair to avoid fibers becoming damaged and brittle.
Wash your hair with shampoo and comb through to remove any tangles, leaving the hair wet for dying. Test a strand of your hair with the bleach to ensure that you don't have a skin reaction to the solution.
Put on the rubber gloves and pour the hydrogen peroxide into the spray bottle. Alternatively, tip the chemical into a bowl if you want to bleach just highlights of your hair.
Separate sections of your hair and spray each in turn with the hydrogen peroxide. Ensure that your hair is still wet as you apply the solution. Start by spraying the back of your head and work forward toward your face. If you're bleaching highlights, apply the hydrogen peroxide using balls of cotton to the strands you wish to dye.
Comb through your hair once it's completely coated in the solution. Tuck all the hair into a shower cap.
Leave the solution in your hair for at least 15 to 20 minutes. Take into consideration that a short time will dye the hair only slightly, but bleaching for longer may begin to damage your hair.
Rinse your hair with cool water and use a diluted shampoo if the bleach doesn't come out easily. Apply a deep conditioner to your hair and leave in for two to three minutes. Repeat the process a second time if you wish to make your hair still lighter in color, particularly if your hair is naturally quite dark.
