8 Natural Ways to Lighten Dark Hair at Home

You can use hydrogen peroxide as a natural hair lightener at home if you're in a pinch. Just keep in mind that it can be a bit harsh, so you should exercise caution and do a test strip before committing to your entire head. Once you've done that, you can use cotton balls to apply the liquid to strands of hair. Similar to how stylists apply highlights in the salon, you can use foil around the sections while it processes. After about 30 minutes, hop in the shower to rinse your hair and make sure to condition.
