Bleaching is a chemical process to remove both natural and artificial pigments from both permanent and semi-permanent hair dyes.

The only thing you need to consider before bleaching is whether your hair can withstand it. If not, it can end up severely damaged. You probably don’t want that.


That’s why you should do the strand test. A simple test will show you your hair’s health.

 Once you’ve made sure that your semi-permanent colored hair can withstand a bleaching session, you should use a 20-volume developer. It’s more than enough to remove the semi-permanent color from your hair. 


Still, wait. While it’s possible to bleach semi-permanent colored hair, it’s key to think about whether it’s necessary.

Is it necessary to put your hair through aggressive bleaching if the semi-permanent hair dye will fade in a few more washes?


The truth, dear reader, is that it doesn’t make much sense.

Depending on the brand of semi-permanent dye you’ve used, the pigments will disappear in 20-25 washes at most.

For example, Manic Panic lasts 15-20 washes. Punky Color lasts 25 washes. They’re the longest-lasting semi-permanent dyes!


 So, instead of bleaching your hair, you can wash it more often. You can do it even every day for the hair dye to fade away. 

Honestly, I think it’s the safest and healthiest option for your hair.

Are you in a hurry to get rid of your semi-permanent hair color because you have an event?


  • Maybe you have your best friend’s wedding and don’t want to show up with Caribbean blue hair.
  • Or maybe you have a romantic date with the love of your life, and you don’t want him to see you with fuchsia hair.
  • Or maybe you have an interview for an important job, and your parrot green hair doesn’t fit the formality required for the position.


So, if for any reason you need to bleach your hair, you can do it only if it’s strong and healthy enough to withstand the bleaching.

How to safely bleach your hair if it’s colored with semi-permanent dye

I’ll test your attention span. What’s the first thing you should do before bleaching your hair to remove semi-permanent hair dye?


That’s right! You should do the strand test.

Many shades of semi-permanent hair dyes require previous bleaching, such as pink, green, or light blue.


If you’ve already bleached your hair to color it, bleaching again to remove it will damage your hair.

That’s why it’s essential to do the strand test. You only have to apply a small amount of bleach mixture to just one strand to see how the hair reacts.

  • If your hair passes the test, you can bleach it.
  • If your hair doesn’t pass the test, you won’t be able to bleach it. But there’s still something you can do. Don’t worry, we’ll get there.


Let’s do the strand test for the time being.

  • Mix a small portion of 20-volume developer and bleaching powder in a plastic container.
  • Comb your hair with a ponytail or bun, leaving only a loose strand in the back.
  • Apply the bleach mixture to the strand and leave it on for 20-30 minutes.
  • Rinse and dry.


Now comes the most important part: check the strand carefully:


  If so, you should decide considering your hair. I’d advise you not to bleach it if any of those signs appear. If you do, you’ll burn it.  And that’s irreversible.

If your hair doesn’t have any of these signs, you can bleach it keeping a few things in mind.


7 key tips to successfully bleach your hair

to maintain the heat

I know that your hair is not damaged and can withstand the chemical process. Still, precautions are never enough. So, take note to avoid unpleasant surprises.

  • Apply coconut oil from the roots to the ends four hours before bleaching. Don’t rinse it. Your hair will be hydrated before the bleaching session.
  • Put 20 or 30 drops of almond oil, coconut oil, or jojoba oil in the bleaching mixture to make it less aggressive.
  •  Don’t use more than 20-volume developer  because the semi-permanent color will fade quickly.
  • Don’t leave the bleach mixture on your hair for more than 30 minutes. Check your color every 5 minutes to make sure the bleach is fading evenly.
  • Rinse your hair with warm, near-cold water to lower the temperature of the chemical reaction. Use your shampoo and conditioner to moisturize your hair.
  • Apply a few drops of repair oil from lengths to ends to avoid the typical post-bleaching frizz.


  Finally, if you’re not sure how to bleach your semi-permanent colored hair, it’s best to go to a professional.  It would be a shame to damage your hair irreversibly, especially if you’re looking to remove semi-permanent hair dye.

So, if you’re not sure about your bleaching skills and don’t want to go to a salon, or, alternatively, if your hair didn’t pass the strand test, you can still do something: fade the color faster.


How to fade semi-permanent hair dye if your hair won’t resist bleaching

In this case, you have to use shampoo and conditioner with extra nutrients and hydration. That way, your hair won’t be further damaged, and you can repair it during the process.


The most important thing about this method for fading semi-permanent color is the quality of the shampoo and conditioner.

  • If we talk about hydration, you can choose Botanical Heart Argan Oil Shampoo and Conditioner or Biolage Hydrasource Shampoo.
  • If you’re looking for deep hair repair, you can choose Elvive Dreams Lengths shampoo and conditioner with castor oil. Alternatively, the gold-labeled Pura D’Or shampoo and conditioner which contains biotin.


  If you wash your hair every day with these shampoos and conditioners, you won’t damage your hair fiber. Instead, you’ll repair and hydrate it. 


Action plan to remove semi-permanent hair dye

Once you have chosen the right products, choose an action plan: you can wash your hair daily or every 48 hours.


If you decide to wash it daily:

In a few days, the hair’s texture will improve, and the semi-permanent hair dye won’t even be noticeable.


If you decide to wash your hair every 48 hours:

  • Wet your hair, apply the shampoo, and leave it for 3 to 5 minutes.
  • Rinse with plenty of water, remove excess water and apply the conditioner for 5 more minutes
  • Rinse your hair and let it air dry.

After a few days, you’ll notice that the semi-permanent color has disappeared without generating extra damage to your hair fiber.



If you want to remove a semi-permanent hair dye, I advise you to fade the with extra moisturizing shampoos and conditioners. They won’t damage the hair fiber.

If you need to remove the semi-permanent hair dye urgently, you can bleach your hair. Remember to do the strand test first.

If your hair passes the test, you can bleach it. If it doesn’t, avoid the process and choose to fade the hair color.
