  • To know how long to wait after bleaching your hair to dye it brown, you should consider its health.
  • If your hair is in good condition after bleaching, you can color it immediately.
  • However, if it gets dry, stiff, frizzes easily, and is difficult to untangle, you should repair it using permanent hair color. You could also use a semi-permanent hair dye. And I’ll tell you why below.

As you can see, to know  how long after bleaching your hair you could dye it brown, you must check it after bleaching. 

That’s the most important thing.

I’ll show you how to tell the difference between healthy and damaged hair.

That is, how to know if your bleached hair is damaged before coloring it.

Bleaching is a very aggressive chemical process. So, if your hair is dry or damaged after bleaching, it could worsen after coloring it.

Bleach is applied with a 30-volume developer. Permanent hair color, instead, is applied with a 20-volume developer.

That means you’d apply a 50-volume developer in just one day.

Do you think dry, damaged hair can survive? Of course not!

 

That’s why you need to know about your hair health first.

 If you apply brown permanent hair dye to your damaged hair, you’ll most likely ruin it.

So, there’re two great tests to check your hair health after bleaching.

First,  take a look at it.  It’s easy to do; you only need to see.

 

The second test is what we colorists call  hair porosity test.  It’s also easy because you only need one hair from your mane.

You’ll also need water and a glass.

So, let’s get to work.

Take these two tests after bleaching your hair and before coloring it brown

Let’s start with the first test: observation.

You need to pay attention and not just take a look.

It’s about watching and paying attention. Your hair will be telling you how it feels after bleaching.

Now, watch:

  • Is it bright?
  • Does it have natural body?

 

Now take a comb and untangle it. Look at the comb.

  • Are any hair strands caught in the comb?
  • Have you untangled it easily?

 

And now, the verdict.

 If you answered yes to all the questions,  you’re lucky. Your hair seems to be healthy after bleaching and will obviously resist the dye.

Now, to be sure, you need to do the porosity test, which will also be useful to know what hair products your hair needs.

We’ll do it together.

 

Now,  if you see that your hair’s dull, stiff, hard to detangle, and you notice a lot of frizz,  it’s not so healthy after bleaching.

Therefore, you’ll have to repair it before dyeing it brown. Still, later I’ll tell you about another option.

Let’s focus on the porosity test after passing the observation test with flying colors.

You’re probably wondering what porosity is. Simply put, porosity is your hair’s capacity to absorb products.

There are three types of porosity: high, medium, and low.

  •  If your hair has high porosity,  it means that it’s damaged because the cuticles are damaged.
  •  If your hair has medium porosity,  it’s slightly damaged and can be repaired.
  •  Finally, if it has low porosity,  hallelujah, your hair is complexed healthy because the cuticles are closed.

 

Are you ready to test your hair for porosity?

  • Fill a glass half full with room temperature water.
  • Now, place some of your longest hair in the glass and wait three minutes.
  • After three minutes, observe the hair.

 

The time has come to know the truth.

  •  If your hair floats on the surface of the water,  it has low porosity. Therefore, you’ll be able to dye it brown and it’ll withstand the chemical process.
  •  If your hair is floating in the middle of the glass,  the porosity of your hair is medium. In this case, you need to repair it. My advice is to repair your bleached hair using moisturizing masks during two weeks.
  •  Finally, if your hair sinks to the bottom,  it’s highly porous. Therefore, your hair is very damaged and brittle. And in this case, I recommend you do intensive nourishing treatments with keratin products for at least three weeks before applying the brown dye.

So far, I imagine that there are two kinds of clients. Some women are very happy because they’ve taken those tests.

Therefore, as their hair is healthy, they shouldn’t wait to apply the brown dye after bleaching their hair. 

 

On the other hand, other women aren’t happy. Now, they know their hair is damaged and they can’t apply a brown dye after bleaching it.

However, I won’t leave you alone. There’s still an option.

If your hair is damaged after bleaching, you can apply a semi-permanent brown dye

Semi-permanent hair dye doesn’t contain ammonia and isn’t applied with a developer. Therefore, it’s a much less aggressive dye than permanent dye.

Now, I want to help you think on your feet with absolute honesty.

  •  After bleaching your hair, you could color it with a semi-permanent brown dye  it it’s damaged.
  •  Alternatively, if it’s seriously damaged,  you could repair it for at least two weeks. Then, apply the semi-permanent brown dye.

 

The advantage of semi-permanent brown dye is that you won’t have to wait to dye your bleached hair, even if it has slight damage.

Still, it also has a disadvantage. A semi-permanent dye doesn’t penetrate the hair core to change the color. It fades more quickly.

Also, you have to wash your hair every three days and use shampoos and conditioners without sulfates to extend the duration of the color.

 

Conclusions

If your hair is damaged after bleaching, you should wait to apply the brown permanent hair color for at least two weeks while you repair your hair.

You can also opt for semi-permanent hair coloring, although I only recommend it for hair with slight damage.

In seriously damaged hair and porous hair, you should perform nourishing and repairing treatments for two weeks. Then, apply the brown semi-permanent hair color.
