Can I bleach my hair again after 24 hours? I don’t recommend it

dye right after bleaching

  • It’s not a good idea to bleach your hair again after 24 hours. It’s also not a good idea to bleach your hair after 48 or 72 hours.
  • You could damage your hair so severely that you’ll leave it on the verge of breakage at best.
  • And in the worst-case scenario, you can burn your hair, and the only solution will be to cut it.
  • Therefore, to bleach your hair again, you should wait at least three weeks.

Bleach, bleach, and bleach.

I don’t know what is wrong with people who take such a complex subject as bleaching in a light way.

I understand that going to a salon for bleaching can sometimes be a luxury moment.


But tell me the truth.

What do you do when you feel bad?


Do you look up a tutorial on YouTube to find out how to treat your condition?

I don’t think so, do you?

You don’t because you feel that following a tutorial may not be the best solution. What’s more, it could worsen your situation.

So, why do you think you should treat your hair differently than the rest of your body?


Can you bleach your hair and have things go smoothly?

Yes, you can. But it’s actually a matter of luck.


 Bleaching is a very strong chemical process by which hair is stripped of natural or artificial pigments. 

Intense chemicals are used on the hair to penetrate inside the core to remove the pigments.

Usually, bleaching your hair once is not enough according to your base color and the color you want to go for.

Then, you decide you need to bleach your hair again as if it worked magically. Do you think you can bleach it again 24 hours later?


How? Not even David Copperfield could do that without ruining his client’s hair.

So, I’ll tell you three things:

  • If you bleached your hair at home, and the color is uneven (the roots and lengths have different colors), I recommend you go to the salon to fix it. Bleaching is a very aggressive process for the hair fiber that can cause breakage from the root.
  • If you bleached your hair, and you like the bleach level you achieved, you don't need to bleach it again. Instead, you can tone it down to eliminate the unwanted yellow undertones.
  • If you bleached your hair and didn't reach the desired bleach level because your hair is still too dark, you’ll need to bleach it again three weeks later.

So, before you jeopardize the health of your hair, let's analyze these options.

If you want to bleach your hair again after 24 hours, you should go to the salon

The stylist will examine how your hair looks after the at-home bleaching.

She’ll probably use OLAPLEX 1 and OLAPLEX 2 when bleaching again to avoid damaging your hair.


Bleaching is the most aggressive chemical process you can expose your hair to. During the process, each hair strand expels natural and artificial colors.

 But in addition to pigments, your hair also expels nutrients, vitamins, and proteins. And that leads to dryness and breakage. 


That's why it's ideal to bleach your hair every three weeks.

 But if you really can't wait, I recommend you go to your salon to have your hair bleached again with the necessary tools to avoid burning your hair. 


If you reached the desired bleach level, you don’t need to bleach your hair again

toning blonde hair

You don’t need to wait for 24, 48, or 72 hours after the first bleaching session.

 If you notice unwanted undertones after bleaching, other solutions are less damaging. You can even go for them yourself. 


Have you ever heard of color toning shampoos and conditioners?

Toning shampoos contain pigments that are deposited on the outside of the hair like a film that neutralizes strident colors.

Do you know what neutralization is? It means applying the opposite color to the one you want to neutralize.


Most toning shampoos are used once or twice a week according to the intensity of their pigments.

 My recommendation is to read the instructions of each manufacturer to use them correctly. 


Here is a very general step-by-step:

  • Wet your hair and apply the toning shampoo from roots to ends.
  •  Leave it on for three to five minutes  according to the manufacturer’s instructions.
  • Rinse with plenty of lukewarm water
  • Apply the toning conditioner for another 5 minutes.
  • Rinse your hair and blow-dry.


You’ll notice that after two or three washes with the toning shampoo, your hair will be free of unwanted colors.


If your hair is still too dark after bleaching, you can bleach it again after three weeks

hydrate colored hair

In the meantime, I advise you to use moisturizing and repairing treatments to strengthen your hair. That way, it’ll be healthier when you bleach it again.

You can use:


 Natural oils are applied two or three times a week, from medium to long hair without touching the roots. 

You can do it overnight and rinse in the morning.


 Moisturizing masks are applied once a week  as follows:
  • Comb your damp hair.
  • Apply the mask from roots to ends.
  • Wrap your hair in a towel to keep it warm.
  • Leave it on for 20 minutes.
  • Rinse without using shampoo or conditioner.


Three weeks later, if you repaired your hair with any of these products, you can bleach your hair again.



To bleach your hair again, you should wait at least three weeks. Otherwise, if you do it only after 24 to 48 hours, you’ll damage it in such a way that you may even burn it.

I recommend asking a professional hairstylist if you have any doubts.
