Do not use products that contain sulfates. Sulfates are great at cleaning your hair, but they can also strip it of dye. If you want to make your color last longer, stick with color-safe, sulfate-free shampoos and conditioners. Most products will say on the label if they are color-safe or sulfate-free. If you are not sure, read the ingredient list on the back of the bottle. Avoid anything with the word "sulfate" in it. Add some of your dye to your bottle of conditioner. This will deposit a little bit of color into your hair each time that you wash it and help the color last longer. Purchase a deep-conditioning mask meant for colored or chemically-treated hair. Apply the mask to damp hair, then tuck your hair under a plastic shower cap. Wait for the time on the package, then rinse the mask out. Most hair masks need to be left in your hair for 5 to 10 minutes, but some need to be left in for 15 to 20 minutes. Read the label, but don't panic if you leave the mask in too long. The more often you wash your hair, the faster it will fade--even with a sulfate-free, color-safe shampoo and conditioner. If your hair tends to get oily or greasy, consider using a dry shampoo between your washing sessions. Much like heat styling, hot water can cause the dye to fade faster from your hair. It can also cause your hair to appear damaged. After you have finished shampooing and conditioning your hair, rinse your hair with cold water for 1 minute for extra smoothness and shine. If you can't handle cold water, use lukewarm water instead. Unless it is freezing outside and you are running late for work or school, let your hair air dry. If you want to curl your hair, seek out a method that does not require any heat, such as foam hair rollers. Avoid straightening your hair, when possible.  If you must use a flat iron or a curling iron, make sure that your hair is completely dry first. Apply a good heat protectant and use a lower heat setting. The sun can cause the color to fade as well. Wear hats, scarves, or hoods when going outside. Much like red hair dye, pink hair dye fades fast. This means that you may have to re-bleach your roots when they start to show as well. If you don't want to re-bleach your roots, leave them natural and re-dye the ends for an  ombre effect instead..  The brighter your pink is, the more noticeable the fading will be. Pastel pinks won't fade as quickly. Some people like the pastel shade that their pink dye fades to. If you like the shade that it fades to, then don't touch it up as often.
