What is Semi-permanent hair dye?

Semi-permanent hair dye is made up of a formula that contains no peroxide or ammonia. This means that, unlike permanent hair dye that does contain ammonia, semi-permanent colour coats the surface of your hair shaft rather than penetrating or altering it.

This makes it more gentle and less damaging or drying for your hair. But it also means that it’s not as effective at covering greys as demi-permanent or permanent colour that penetrates deep into your hair to alter its colour.

Semi-permanent dye is excellent for enhancing your natural colour so you won’t get unsightly roots growing out like you will with permanent dyes. But it’s also not as effective at covering greys as permanent colour and semi-permanent hair dye won’t last as long – around 10-12 washes.

It’s still pretty stubborn at being removed but we know of a few ways that work to get that colour out and back to your original base hair colour.

Method #1: How to remove semi-permanent hair dye with shampoo.

  1. Get a small bowl and fill it with warm water.
  2. Add some shampoo to the water.
  3. Use a large toothbrush or scrubbing sponge to work up a lather in your hair.
  4. Keep rinsing until all of the colour is gone.
  5. Repeat steps 2-4 until all of the dye has been removed from your hair, then wash with cold water for one final rinse
  6. Apply conditioner for soft, shiny hair!

Method #2: How to remove semi-permanent hair dye with baking soda.

  1. Completely wet your hair in the shower.
  2. Apply conditioner to your hair and leave it on for 10-15 minutes.
  3. Shampoo your hair with a clarifying shampoo.
  4. Rinse out the conditioner and the shampoo.
  5. Apply baking soda to your hair, leave it in for 1 minute, then rinse it out.
  6. Wash your hair with cold water until you feel like there is no more dye left in there.

Method #3: How to remove semi-permanent hair dye with hair dye.

  1. Find a colour that is of a similar shade to the hair dye you are trying to remove. Buy at least two boxes.
  2. Apply the new colour over the semi-permanent dye until your hair becomes saturated.
  3. Leave for the maximum development time as instructed and then rinse with cold water and shampoo.
  4. Repeat steps 2 and 3 until all of the semi-permanent hair dye has been removed.
  5. Apply conditioner after washing your hair, then rinse again with cold water and shampoo.
  6. Wait at least two days before dying your hair again (or longer if desired).

Method #4: How to remove semi-permanent hair dye with bleach.

  1. Wear protective gloves and protect all surfaces!
  2. Mix the bleach formula from a hair bleach kit as instructed.
  3. Apply the mixture to the hair with a cotton ball or sponge, saturating it well.
  4. Leave it on for 5-10 minutes before rinsing out with water until all traces are gone from your hair.
  5. Rinse again with cold water to close up the cuticles of your hair shafts and seal them against future damage.
  6. Be sure not to get any bleach in your eyes, nose, mouth or skin during this process! If you do, rinse thoroughly immediately.
