I need some help restoring my hair back to light brown

If you went for a brown and it came out darker than you expected, wait a few weeks (2 or 3) before recoloring. During this time, your color should fade and lighten a few shades.

After this time, if you are still unhappy with your hair color, the best, most quick, and easiest way to fix it is to seek the assistance of a professional stylist. Take a photo with you to show them how you want your hair to look, and you should have your desired color in no time flat!
