Dyes to lighten dark hair without damaging it (dyed hair or natural hair)


from brunette to blonde

Are you thinking of lightening your dark hair with a dye?



If so, before applying the dye, you should bleach your hair.

Many people with black or dark brown hair make the mistake of thinking that they can dye their hair blonde by simply applying a dye.

I hate to disappoint you, but that’s not the case.



 The only way to lighten your hair is to first bleach it, and then apply the color, which could be a dye or a toner.  

All of this is supposing that you want to lighten virgin hair, hair that has never been dyed.

If on the contrary, you have dyed hair and you want to lighten it, the process changes a bit.


That’s why, today, I want to tell you what the lightening process consists of for hair both natural and dyed.

But remember, always when you apply the dye after bleaching.




Because dyes can only lighten barely one or two tones, and that’s only if your hair isn’t completely black.

So if you have black hair, you will never get to blonde unless you bleach it.

No matter what color you want to get your dark hair to when you lighten it, the process is basically the same.



That’s why, today, I will tell you:

  • How to lighten your dark, virgin hair (never been dyed)
  • How to lighten dyed hair
  • How to care for your hair after you apply the color so that you don’t ruin the color.



How to lighten dark, virgin hair

Dark hair is a very sensual and elegant color, but we live in a world of change, where colors have invaded the heads of the greatest starts in Hollywood.


We see these almost daily magical transformations when they go from black hair to an almost platinum blonde.


However, don’t be fooled by those “before and after” miracles. None of them happened in fifty minutes. Behind the scenes, they hide various sessions, especially for people that have already dyed their hair.

And don’t even start with black hair. This is one of the most difficult colors to get out.

You’re going to have lots of problems.



If your intention is to lighten your dark hair, it’s important to consider if your hair is naturally dark or if you got that color with a dye.

  • If your hair is naturally dark, you have virgin hair, and it is easier to lighten it as long as your hair isn’t black.
  • If you have dark brown hair and you want to lighten it one or two tones, you can use a lighter brown dye.
  • But you should use a 30-volume peroxide, since this is the one that will penetrate the cuticles of your hair, allowing the new color molecules of the dye to be deposited in the stalk of the hair.

Like I told you before, this only will work for lightening brown hair one or two tones.


Now, if your hair is dark brown or black, and you want to lighten it more than four tones, things change. Because you should bleach your hair so that after, you can apply the dye.

As you well know, bleaching is a chemical process that damages the hair a lot because it uses chemicals that change the internal structure of the hair.

And also, depending on the tone that you want to get, you may have to bleach your hair twice.

Because, basically, it has to do with breaking down the color of the hair, until it becomes white, so that after, you can apply the dye.

Now, there are a few rules that it’s good to keep in mind when it comes time to choose a color tone.


If you want to dye the hair a lighter color, use a dye for the hair that is colder than the color you want.

Also, you should keep in mind that if you bleach black hair, during the bleaching process, red pigments will appear because the base tone of your hair will become visible.



That’s why, to dye your naturally black hair after bleaching it, you will have to neutralize those warm tones so that the hair looks natural.


Choose a dye that neutralizes these orange and copper highlights. Generally, dyes that have ashy undertones work very well.


How to apply the dye to lighten dark hair

Surely, within the box of color that you chose, you will find two products that you should mix.

The dye and the developer, since this is what pushes the reaction of the color and makes your hair dye more permanently.


The easiest way is to divide your hair in four individual sections. You can do this separating the hair in the middle from your forehead to the base of your neck, then again from ear to ear. This will leave you with four quadrants to work with.


  • Now that you have your hair sectioned into quadrants, start to apply the dye in the first quadrant from the lower part of your head, working around to the front.

When you apply the dye to a quadrant, lift up small layers of the section where you are working and apply the dye on both sides of each piece. Continue working down from the upper part of the quadrant until you have completely covered that section.



  • To get maximum lightening and reduce fading of the final color, you should let the dye sit for the time recommended by your brand of dye.

Generally, it can be betwee 35 and 45 minutes. Once that time has passed, simply rinse the dye and you can enjoy your new color.


How to lighten dark, dyed hair

If your dyed hair is very dark and you want to lighten it, you should use a color remover before the dye.

Because this way, you will be sure to remove as much of the artificial color as possible for a healthier, more even result.


 Once you have removed the color, you should wait at least five days to apply a new dye. 

You should wait these days because if you apply the dye too soon, you could cause severe damage to the hair follicles, leaving the hair dry and broken.


The hair remover works by entering the stalk of the hair and breaking the big color molecules that are deposited in the hair. The color molecule particles become small enough to be eliminated from the hair.

This product will not only eliminate synthetic pigments from the last time you colored your hair, but also from all the colors before that.


Now, the remover won’t lighten the natural color of your hair. It’s a product that is designed to only eliminate pigments from permanent dye.


Once you have removed the previous dye from your hair, and depending on the color that you want to get to, you can bleach or dye your hair.


If you want your hair to be a lighter tone, and you still have dark brown hair, you should bleach it before applying the new dye.

If after removing the previous dye, you only want to lighten it one or two tones, you can color it.

It will all depend on the color that you are going from and the one you want to get to.



Although, I repeat, between these processes, it is best to wait between five and seven days to prevent unnecessary damage to the hair.


How to care for your hair after applying the dye to not ruin your hair

Since dyed hair is weaker when it’s wet, you should avoid brushing it, because it will increase the probability of breakage.

Get used to softly drying your hair with a towel instead of using brisk movements and wrapping the towel around your hair.


 Do you use hair dryers, flat irons, or curlers regularly?  

Try to use them in the lowest temperatures possible and always after applying a thermal serum.



It is also advisable that you apply some sort of intensive hair treatment to your hair at least once a week.

You don’t have to go running out to buy a hair mask, olive oil is an excellent hydration treatment that nourishes, strengthens and reduces frizz in dyed hair.


Now you know how you can lighten your hair using dyes. And you also know that in most cases when you want to lighten your dark hair, you should bleach it first.



The color theory is something that is extremely complicated.

That’s why, if you aren’t sure, it’s always best to go to a professional salon.

Because bleaching and coloring will always be chemical processes that can damage your hair, in some cases, irreversibly.


And now, I would like to know more about you. Are you thinking of lightening your hair?
