Can I Bleach My Hair Twice In One Day?

We agree to all sorts of treatments to make our hair look fresh and lovely, but we are not always fully aware of how those treatments might damage it. 

We have dyed it and bleached hair numerous times, but we pay little attention to the time between those treatments. Short time intervals between treatments can seriously damage our hair, especially when bleaching it. Someone might even think – can I bleach my hair twice in one day?

Don’t let your hair suffer. Stay with us, and we will explain everything you need to know about the bleaching process, how often you are allowed to bleach your hair, and some more helpful information. 

Bleach Twice In One Day – No Way!

If you ever considered bleaching your hair twice in one day, get rid of that thought

Even one bleaching is harmful enough, let alone two! 

You should be fully aware of what bleaching does to your hair: It not only makes the color from your hair disappear; it also makes it more fragile. 

To be more precise, it eliminates the pigment in the stalk of your hair. This is a very delicate process, and you shouldn’t make your hair go through it twice in one day. 

When done correctly, it can leave you with good results. But imagine something going wrong, and you are bleaching it twice? Goodbye to all your hair.

You should also have in mind that the level you are trying to achieve largely depends on the type and stage in which your hair is currently. 

Is Bleach Really That Bad?

Anyone who has ever bleached their hair knows how lengthy and demanding this process can be. Even when done by professionals, bleaching your hair is not so good

Bleaching might be seen as a combination of science and magic.

But it is not just the bleaching that harms your hair. Styling it and outside factors also play a significant role in this. 

As we said earlier, the level you are hoping to achieve might need several bleaching appointments, but never one after the other. Even with gaps between the treatments, your hair will suffer to some extent. 

Bleaching your hair can have some hazardous side effects, and you should be familiar with them:

  • Hurting your scalp – since this procedure is quite lengthy and takes a couple of hours, it can itch and damage your scalp. If you feel any itching or pain during the bleaching process, remove the bleach at once and save yourself from chemical burns.
  • Hair getting dry – bleach takes the color out of your hair, making it extremely dry. You can prepare for this and minimize the dryness by regularly hydrating your hair. 
  • Ending up with discolored hair – this is not so common, but it can still happen. This would probably happen to someone trying to bleach their own hair and not mixing the ingredients properly. 

After you have bleached your hair, it will become more prone to damage. And because of this, you will need to take good care of it. Yes – bleached hair requires high maintenance.

You should equip yourself with different kinds of protective products that are meant for your hair type and use them, preferably on a daily basis.

How Often Can I Bleach My Hair?

It is evident that bleaching is a hair treatment that should be taken seriously and that you should under no circumstances bleach your hair twice in one day. So, how long do you wait?

This depends on many factors – the type of your hair, color, and condition.

If your hair has been damaged in any way, you shouldn’t do this on your own. Our recommendation is to go to your hairdresser and let him do the strand test – this will determine how long the bleach should stay on your head. 

As for the gaps in between bleaching appointments – do not think of bleaching it again after one week if you want to save your hair. The time frame is much longer, and you should respect it.

Every good hairdresser will advise you to come for another bleaching after 4-6 weeks, and this is just the right time. 

This will not overwhelm your hair too much, and it will give it some time to “breathe.”

Although this is not highly recommended, some people are not professionals but manage to make it happen without any problems. 

If you have decided to bleach your hair alone, you need to be extra mindful and concentrated.

Do not miss out on any steps or ingredients, because they are all essential.

Okay, let’s get to work. 

First off, you will need the following products:

  • A liquid or powder lightener and developer (20, 30, or 40 volume) – the darker the hair, the higher work you will need.
  • A toner – be careful when choosing this.
  • A gown – this will protect your clothing from possible stains.
  • A brush, gloves and a plastic cap – this can be bought as one kit.
  • A large and a tail comb – both are required.
  • Regular shampoo and conditioner – these two will be used during the process.
  • Purple shampoo and conditioner – this will help the hair tone after bleaching.
  • Sulfate-free shampoo – for hydrating your hair. 

Now, the process itself.

  1. Mixing the lightener and developer and applying it evenly to hair
  2. Covering the hair with a shower cap and letting it sit.
  3. Washing, conditioning, and letting your hair dry.
  4. Using toner to get the perfect color and brightness.
