Pros and Cons of Dyeing Your Hair Black (no one tells you about)


 Do you want to dye your hair black? Want to know if your hair will go back to normal? 


Well, if you read the first lines carefully, you probably already know: if you dye your hair with permanent black dye your hair won’t go back to normal.

Because  permanent black hair dye contains chemicals that change your hair’s color forever. 

Therefore, if you get tired of black, you will have to apply another chemical process to remove it.


And if you don’t want to apply a chemical process because you’ll dry out your hair, you have only one option. Let your hair grow out. It will grow with its natural color. Then you’ll have to trim the ends, to slowly eliminate centimeters of dyed black hair month by month.

That’s why I recommend you think about other options before using black hair dye.

For example, if you want to darken your hair, you can opt for brown hair dye, which contains less persistent pigments than black hair dye.

You can also use a semi-permanent black dye, but we’ll look at this option later. For now, let’s take a look at how black permanent hair dye works on your hair.


If you dye your hair with permanent black hair dye, your hair will not return to normal

Why not? It’s because you apply permanent hair dye with developer and the dye contains ammonia. The mixture of these two chemicals opens the cuticles of your hair fiber so the color penetrates to the core of your hair.

Once it gets to the core, the ammonia attaches the color to the melanin, which is the protein that gives your hair its pigmentation.

In other words,  permanent black hair color changes the natural color of your hair forever. 


So if you dye your hair black and you don’t like the color, you will have to apply either bleach or a color sweep. Both processes are chemical. Therefore, they can dry out and damage your hair.


If you don’t want to bleach all your hair, you can get a balayage or highlights to gradually fade the black dye.

Another option is to let your hair grow out and trim the black parts each month. Of course, although this option is healthier for your hair, it will also take longer.


If you dye your hair with semi-permanent black hair dye, your hair will return to normal

Why will your hair return to normal here?

Because  semi-permanent black hair color doesn’t contain ammonia and you don’t apply it with developer. 


It’s simply deposited as a film of color on your hair, which gradually fades with washing.

But depending on your hair color, this will take more or less time.

Why will it take more or less time for your hair to go back to normal?


Because  the lighter your hair color, the longer it will take for the semi-permanent black dye to fade. 

  •  What if your hair is very light blonde 9 or extra light blonde 10 ? After many washes, if the black doesn’t disappear, you may need to resort to a light bleach to remove it completely.
  •  What if your hair is brown 4, light brown 5, dark blonde 6, blonde 7, or light blonde 8 ? You can remove traces of semi-permanent black dye by using a clarifying shampoo.


If you want to make the semi-permanent black dye fade faster from your hair, you can wash your hair frequently using a detox shampoo.

Or if there is still some black residue, you can apply another semi-permanent dye such as brown 4 or dark brown 3, which will cover it perfectly.



Once you apply a permanent black dye, your hair will never go back to normal. Why not? Because permanent hair dye changes your hair’s color forever. Therefore, to remove the dye, you will have to resort to bleaching.

So, if you’re still not sure about darkening your hair by using black hair dye, you have two options. You can use a semi-permanent black hair dye or darken your hair with a brown hair dye.
