Hair has different needs and after bleaching, once your hair is always sensitized. Each hair is different and just as some might be ready to repeat the process at that very moment. Many others do not, they even run the risk of breaking. That is why we cannot generalize this answer for everyone because it depends on certain things.

The first thing is that you avoid doing it the same day. Hair always requires recovery and to do so I consider it very aggressive.
Hair should always be tested before bleaching again. Below I will explain how.

What are the conditions to bleach my hair Twice?

The conditions for a second lightening are mainly based on the condition of the hair. Also, during the application are some aspects to consider to ensure the safety of the process. All this will help to keep your hair protected the much as possible. To help you know when would be a good time to do bleaching a second time I will dive into 3 aspects:

  1. Sensitization level.
  2. Recover the nutrients of the hair.
  3. Remove bleach in time.

Based on these topics you will feel more confident that your hair will be safe before applying any lightening product. Removing the product at the right time is key to keeping your hair in good condition. So I will also tell you how you can do this and why it is important. Hair is a feminine accessory that can be beautifully worn if it is well cared for.

Let’s look at each point in detail.

#1 Sensitization level

This is probably the most important point because the hair must be ready to bleached again. A test must be carried out on a hair strand to be sure that the hair will resist a new aggression

Take a strand of hair and in the last 3 fingers of the tip, make a half turn and pull it slightly but firmly about 1cm out. If the hair breaks or stretches like a rubber band. Re-bleaching is not recommended. You could be at risk of your hair not resisting it and breaking.

What should be done in this case is to wait at least 1 month and perform this treatment every time you shower it at least 3 times a week and always leave a day of separation without getting it wet.

You can apply it Monday, Wednesday, and Friday. So the other days it gives it time to dry inside and you keep it with controlled humidity. This is how hair should be treated.
For best results, use it with the shampoo from the same line and you will double the result.

Split Ends

If your hair only has split ends but it was not stretched in the test or it broke, it is important that you still recover it. You have to add some nutrients and end sealing to prevent it from becoming too sensitive when applying the second bleaching and reaching the point of breaking.

For that, it is good that you read below about recovering the nutrients of the hair because it is extremely closely related. Once you know you have split ends it is an immediate wake-up call to act and repair that hair. Much faster if you intend to bleach it.

#2 Recover your nutrients

Whenever you have used bleach it is extremely important to restore the lost nutrients to the hair. Undoubtedly, using bleach sensitizes the hair. In short, I tell you that the hair is weaker after having bleached it. This can be for highlights, a balayage, a color wash, or anything to do with it.

You always have to balance it in its PH and in the protein chains, it needs to be strong. My recommendation is that you always wait a month after the first lightening, applying the necessary home care treatments with a good washing and conditioning routine. Actually getting color is only 50% of the look you want. The other 50% is given by the texture and shine of healthy and nourished hair.

If in the previous test the hair strand did not break or stretch, it is a good sign. To recover your hair you must return the nutrients that give strength to the fiber. These are especially the proteins that you can find in very specific products. The proteins must enter the cortex so that they can reinforce the chains and bonds that make the hair united and strong.

I recommend the Kerastase Therapiste Serum because it really gives very good results using it correctly and routinely. Constancy is very important to recovering any hair. Use it at least 2 times a day just in the tips for at least 2 months. This will close your ends, allowing you to feel your hair manageable, soft, and shiny. After you perform one more time the strand test, you are good to go, and bleach your hair again carefully.

#3 Remove bleach in time

Depending on whether you want to bleach it yourself or go to a beauty salon. Which I always recommend because discoloration is something quite delicate. A professional will be able to monitor the process much better to ensure that both the color and the texture are good.

Removing the product at the right time is key to keeping your hair in good condition. Bleach acts only for 45 minutes since is mixed with the developer. Always monitor your hair very well, especially in the last 4 fingers of the hair. It is where it tends to be more sensitized. I recommend you check it every 15 minutes so you don’t have any surprises.

If for some reason you have to rinse before the whole 45 minutes, do not worry, you will be able to achieve better lightening after recovering your hair again. Patience is always rewarded so don’t despair. It is always better to wait than risk breaking or damaging your hair.

You can also see on this post about bleaching on wet hair that is gentler on the hair although less lightening but can be a good alternative when you want to lighten your hair twice.

Additionally, you can check if the highlights damage your hair in case this is the effect you want to have on your hair to learn more about this topic.
