Gabrielle demonstrates how to bleach your eyebrows with peroxide at home. Bleaching your eyebrows is helpful for people who frost or bleach their hair and need to lighten their eyebrows to match their new hair color. Put a little bit of everyday household peroxide on a q-tip and swipe it across your eyebrow. Make sure there's not too much peroxide on the q-tip so it doesn't drip down. Leave the peroxide on overnight. When you wake up the next morning, just wash your face and you will see your newly lightened eyebrows. Repeat the process for three nights in a row. Extend the bleaching process to achieve lighter eyebrows.
