After you have bleached your hair, you need to decide which color you want to have. The cuticle layers of your hair strands have been disrupted in the bleaching process, which allows hydrogen peroxide (a key ingredient in hair bleach) to penetrate the hair strand and strip out color. Depending on your hair's natural color and how long you left in the bleach, your hair now might be yellow, white or reddish. Your hair is now ready to take on color, and will often take color much more quickly and deeply than if you hadn't bleached your hair. You might choose to dye your hair a natural color, such as shades of brown, black, red or blond. You might also choose a color like cherry red, blue, purple, pink, and so on. For more natural color effects, stay within 1-3 shades within your own natural color.  Consider the base color of your hair after bleaching and the base color of the dye you are going to use. These might conflict and give you the wrong color. If your bleached hair is yellowish, and your dye has a blue base color, you might end up with greenish hair.

To figure out your dye's base color, check the dye manufacturer's website for a "palette list" or similar, which categorizes colors into warm, neutral and cool shades. You can also buy different components of a hair dye kit at a beauty supply store. These products will indicate their base color on their package (i.e., blue, blue-violet, violet, violet-red, red, etc.). Paying attention to the color palette of hair dye will help reduce the risk of ending up with the wrong color in your hair. Look at your hair in childhood photos.

Similarly, if your hair was a cooler color (ash blonde, brunette), your hair will likely...
