Can I apply a dark ash blonde color over my dark brown hair?

starting from dark hair

  • If you apply a dark ash blonde dye to your dark brown hair, it will only make your roots lighter. The rest of your hair will still be dark brown.
  • A hair dye will never have the power to lighten hair more than two shades. In this case, there are three shades between dark blonde and dark brown.
  • What you need to do is to bleach your hair and then apply the dark blonde dye. Also, be aware that unwanted shades appear in your bleached hair. You can neutralize them with the appropriate dark blonde dye. Here’s how to do it.


Dyes can work wonders, but, as far as I know, they don’t work magic. Why am I telling you this? Because if your hair is dark brown, no dye can take it to a blonde shade.

It does not have to do with the best dye on the market, the most expensive one, the most recommended one, or the same dye used by professionals in the salon. The dark ash blonde dye will not lighten your dark hair.


 Unfortunately, you’ll have to bleach your dark hair firstly. Then, apply the blonde shade you want most. 

It is all about math.


In the color palette, dark ash blonde is number 6.1, and dark brown is number 3.

As you can see, there are three shades of difference between them. So, for your hair to retain the blonde dye’s pigments, you’ll need to go through a bleaching session.


What you’ll need to do to get to dark blonde ash is summarized in three steps:

  • prepare your hair for bleaching
  • bleach it
  • apply the blonde dye

Are you willing to follow these steps?


Then, stay with me because I’ll tell you:

  • How to prepare dark hair for bleaching
  • How to bleach dark hair to apply the blonde dye
  • How to apply dark blonde dye to pre-bleached hair


You must realize that bleaching is a very aggressive chemical process. Therefore, preparing hair to cope with the process is crucial. One misstep and your hair will end up burned, literally.

How to prepare dark hair for bleaching

Bleaching will remove your dark pigments. Later, the hair fiber can absorb dark blonde pigments.

However, it’s a process that damages the hair fiber, leaving the hair dry and porous.  To minimize damage, you need to deeply moisturize your hair, both before and after bleaching,  using oils, moisturizing masks, and keratin treatments.

Would you like to know how to use each of these options correctly?


  • Oils: coconut, argan or olive oil.

Oils are an excellent option because hair absorbs the oil, retaining moisture. It is best to use them the day before you bleach your hair.

You can use coconut or argan oil and leave it in your hair overnight, but if you use olive oil, leave it in for 1 or 2 hours only.


  • Moisturizing masks.

These masks, besides moisturizing, restructure the hair fiber. You must apply them to your brown hair 15 days before bleaching.

Moisten your hair and apply the mask from root to tip, leaving it on for 20 minutes.


  • Keratin treatments.

This option is much easier. All you have to do is use shampoo and conditioner with keratin.

Every time you wash your hair,  use this shampoo. This way, the keratin, a protein, will repair any previous damage to your hair before bleaching it. 


Once you’ve made sure that your hair is strengthened and that it will be able to resist the bleaching process, you’ll be much closer to taking your hair to dark ash blonde.


How to bleach dark brown hair to dark ash-blonde

with gloves

Bleaching is a straightforward process. It is important to respect the exposure times because your hair may suffer permanent damage if you exceed 45 minutes.



  • 30 volume developer
  • 1 bleaching powder
  • Coconut oil
  • Gloves
  • Dye brush


  • Step 1: prepare your hair.

Untangle your hair, and section it into 4 sections to be held with clips. This way, it will be easier for you to apply the mixture.


  • Step 2: preparing the mix.

In a plastic container, mix the 30 volume peroxide and the bleaching powder, adding 10 drops of coconut oil.


  • Step 3: applying the mix.

Put on your gloves and, with the help of a dye brush, apply the bleach mixture to each of the 4 sections of hair you separated. Always start with the mid and ends of each section.

Once you finish, continue to apply to roots and growth, and wrap your hair in a shower cap.

 Let the bleach mixture work for 20 to 40 minutes, checking your color every 5 minutes.  


  • Step 4: rinsing.

After the exposure time, rinse your hair with warm water and wash it with shampoo to remove any bleach traces.


Once your hair is dry, check to see if it has bleached evenly. If it has, the moment has arrived. But wait! Are you sure that dark ash blonde is the color you want?


How to apply the dark blonde dye the right way

Earlier, I asked you if you were sure that the dark ash blond tone was right for you.

That question has an explanation. Since you bleached your hair from a very dark color, unwanted shades, such as orange or red, may have emerged.

That’s why you have to think carefully about what shade of dark blonde you want. Dye colors have a tone or secondary tone indicated by the number after the dot.


 In this case, dark ash blonde is 6.1. This means that its secondary tone is blue. So, it will perfectly neutralize the orange reflections. 

Now, if your hair shows unwanted yellow or red tones after bleaching, you should choose another dark blonde tone.

  • If your bleached hair appears yellow, you should choose the dark iridescent blonde, 6.2.
  • If your hair is red, you should choose a dark metallic blonde, 6.7.


Once you have the right shade of dark blonde, it’s time to apply the dye.

  • Section your dry hair into 4 sections to make it easier to apply the color.
  • In a plastic container, mix the dye and the developer until you get a homogeneous consistency
  • Put on your gloves, and with the help of a dye brush, apply the mixture in lengths and ends, to continue on the roots and growth.
  • Let it develop for 40 to 45 minutes. Then, rinse with plenty of warm water.


Now, you will have gone from a dark brown to a dark blonde. Best of all, you’ve done it with minimal damage to your hair.



It is impossible to go from dark brown hair to dark blond hair without bleaching previously.

To bleach your hair, you must perform intensive hydration treatments at least fifteen days before the process.

Remember, once you have bleached your dark brown hair, you must choose the right shade of dark blonde, with its corresponding tone. This way, you will ensure that the dye neutralizes the unwanted shades that may appear after bleaching.
