Dark brown hair go lighter without dyeing it?

Just fyi, i do this to my hair, too. Been doing it for years now, so yes it works. First, go in your medicine cabinet and look for hydrogen peroxide. If not, go to your local CVS / Rite Aid / Walgreens / whatever and buy it from there. If you don't have a spray bottle at home that you can use to fill this, get one while you're there. Fill the bottle (but please, don't mix up any chemicals) and spray it onto your hair liberally AND evenly. Don't forget the back of your head, just because you can't see it.. It should be very wet, but not like it's dripping wet. Use a comb during this process, as it will be easier and spread more evenly. Don't put your head on anything that will get bleached. Takes a few hours, you'll see the results as it progresses. Wash and rinse your hair like you normally do, and repeat the process during the following weeks till you get your desired color. Once you do, you only have to retouch every 2 weeks/ 1month when it grows out a bit. Don't hesitate to e-mail me if you have any other questions. Hope I helped =]
