    You should apply a semi-permanent color to clean, damp hair. Make sure it has been thoroughly towel-dried. If it is too wet it won't properly absorb the color.

    Semi-permanent color is a stain that begins to fade with the first shampoo. Demi-permanent is similar to a very mild form of permanent color as it chemically deposits color molecules under the cuticle for a longer-lasting effect.

    It depends on the type of color you are applying. Permanent color should be applied to dry hair. Semi-permanent color will be absorbed the best on freshly-washed and toweled-dry hair.

    Semi-permanent dye is a very mild form of color that will not damage hair. Unlike permanent color, it doesn't change the hair through a chemical process but rather stains it with pigment.

    Yes, your color can fade from washing it. Try to minimize how often you wash your hair.
  • Question
    If I have brown hair, do I need to bleach it to dye it black?
    Community Answer
    No. Black dye will cover anything, you'll be fine without it.
  • Question
    Should I use a blow dryer on my hair after applying the dye?
    Community Answer
    Yes, but put a shower cap on (after applying the hair dye). Then, use the blow dryer on your shower-capped head for about ten minutes, being sure not to hold the dryer too close). Then rinse your head with cool water, followed by a cold rinse and a conditioning.
  • Question
    How do I bleach my hair if I have brown hair?
    Community Answer
    You can usually buy bleach at any store that sells hair dye, but it would be a better idea to get your hair bleached professionally. A lot can go wrong while bleaching your own hair.
  • Question
    Should my hair be completely dry before applying semi permanent hair color?
    Community Answer
    Yes. When your hair is wet, the water blocks the dye from really getting to the hair shaft and latching on. Same deal with any conditioner. So just wash with shampoo, don't use conditioner, and let it dry completely first. You need your hair to be bone dry.
  • Question
    Should I rinse my hair with hot or cold water?
    Community Answer
    Rinse with warm water until the water runs clear, then do a final rinse with cold for a few seconds to close the hair cuticle. Avoid ever using hot water on your hair, as it can be damaging.
  • Question
    If my hair is brown, but not that dark, do I really need to use bleach on it?
    Community Answer
    It depends on how vibrant you want the color to be. I suggest doing a strand test first, then making a decision about bleaching from there.
  • Question
    Is it possible to maintain the bleached color of my hair after the semi permanent dye is all out?
    Community Answer
    If you bleach your hair, it will stay like that (except for the roots, of course).
  • Question
    Do I really need to use bleach?
    Community Answer
    Only if your hair is black/brown, but bleached hair will have a more vibrant color.
  • Question
    Can I dye my kids hair?
    Community Answer
    Yes, if your child is okay with it.
  • Question
    Where can I get the bleach to put in my hair?
    Community Answer
    You can buy it at most stores that sell hair dye. A beauty supply store such as Sally Beauty will definitely have it, but you can probably find some at your local Walgreens.
  • Question
    I want to dye a small amount of hair, wrap it up in something, and go to sleep. Is there anything wrong with washing it out in the morning? Is there any risk?
    Community Answer
    The only risk I see is the possibility of the color transferring from underneath the covering onto your skin, clothes and sheets. Leaving the color in overnight will make it take a lot better and make the color brighter after you rinse it in the morning.
  • Question
    I dyed my hair with semi-permanent hair dye, then rinsed after 40 minutes. The dye came out. Should I wait longer?
    Community Answer
    Usually, when you rinse after applying dye, there'll be a lot of dye that comes out. But if none of the color stuck, you should try a different brand or pre-lighten your hair. It could be that your hair is too dark.
  • Question
    Is it possible to use semi-perm hair dye over permanent hair color in order to blend it in better?
    Community Answer
    In the mechanical sense, no. It will not make the permanent color blend into the hair any better physically. However, in terms of the color, yes, using a semi-permanent color after you dye your hair with a permanent color will add to the colors you already deposited. For instance, if your hair turned out too red, you can add a semi-permanent color to counteract the red.
  • Question
    Can I put a semi-permanent over a wash in/out color or do I have to wait until all the color is washed out?
    Community Answer
    If you have wash-out color still in your hair when you dye it, it may make it more difficult for the semi-permanent dye to penetrate your hair very well, so I would be careful about that.
  • Question
    Does it have to stay on for 30 minutes?
    Community Answer
    If you're bleaching your hair, then you should keep it on for 15-30 minutes. If you're dying your hair, then I would aim for 30 to 45 minutes.
  • Question
    Can I use a semi-permanent color to temporary highlight my hair?
    Community Answer
    Yes, you can.
  • Question
    What is the best way to color a shaved cut?
    Community Answer
    Pour the dye into a non-metal bowl and use the color/tint brush to evenly coat your hair.
  • Question
    I've been told that black semi-permanent dye from a box will not wash out. If I want it to eventually wash out, could I dye my hair while damp to ensure this?
    Community Answer
    If you dye your hair while it is still damp, it might not even color your hair enough, and you might have discoloration. Also, black semi-permanent dye would wash out eventually, I'm sure, but it may take longer than other colors.
  • Question
    Do I need to mix the hair dye with anything like creme developer?
    Community Answer
    No, you don't. Semi-permanent colors do not need developer.
  • Question
    Can I leave semi-permanent hair dye in my hair for hours without damaging my hair?
    Community Answer
    Yes. It doesn't have the same chemicals as permanent dye, so it is safer to leave in.
  • Question
    I dampened my hair this morning. Can I still dye my hair tomorrow?
    Community Answer
    Yes. Once your hair is dry you can begin to dye. You don't need to wait a whole day. Just make sure your hair is not wet during the process, as water cancels out the dye.
  • Question
    Will chlorine make it fade? If so, how can I prevent that?
    Community Answer
    Yes, it will. You can't really prevent it, but wearing a swim cap will minimize the damage.
  • Question
    Will the dye come off on clothes or furniture if the hair gets wet?
    Community Answer
    Yes, especially the first week. Put print pillowcases on your pillows and use dark colored towels when drying your hair after washing it.
