Lemon Juice

• If you have naturally light or blond hair, you can take a more natural approach to lightening your hair. Spraying your hair with lemon juice while you're in the sun can effectively sun bleach your hair. Rinsing your hair with lemon and chamomile tea will also lighten your hair by a shade or two. These methods are both safe and easy, without using harmful chemicals that can dry out and damage your hair.
  
  

Toners and Semi-Permanent Dyes

• If you'd like to lighten your hair without the commitment, use a toner or semi-permanent dyes Since these products will not permanently dye your hair, they are not very effective for those with dark brown, dark red or black hair. Toners and semi-permanent dyes are applied to your hair like regular hair dyes and will lift -- or lighten -- your hair color about two to three shades. The best part of these products is that if you hate the color, it's not a problem, as it will simply wash out in one month.
  
  

Permanent Hair Color

• For longer-lasting lightening, you can dye your hair with a permanent hair color. Permanent hair dyes will lift all colors of natural hair; however, it's important to keep in mind that black, dark brown and even medium brown tones will not be able to be lifted to a blond shade effectively. Permanent hair colors can lift your hair about four shades lighter. So if you have dark black hair, you can be as light as a chestnut brown, but to be blond, you'll need to skip to Section 4.
  
  

Bleaching

• Bleaching your hair is the highest level of lightening you can perform on your hair. Bleaching -- with a mix of peroxide and hair bleach -- can lighten even jet-black hair to white blond. After you've successfully bleached your hair, you can then dye it any lighter shade that you'd like. Although this is very effective for all hair colors, it can be quite damaging and cannot be redone until your hair grows out. For that reason, before you commit to bleaching your hair, make sure you're 100 percent ready for your new hair color.
