I don’t care because my experience, knowledge, and common sense tell me that it’s impossible for you to bleach your hair twice with a 30-volume developer on the same day without ruining it.
For those who haven’t heard, bleaching is the most aggressive chemical process that can be applied to hair. The word bleach should be written in red letters like “ALERT”, “CAUTION”, and “STOP” signs.
Let’s not fool ourselves.
The moment you bleach your hair, in addition to removing the color, you remove moisture and essential nutrients that make hair healthy and strong.
Now, can you imagine what could happen if you bleach your hair twice with 30-volume developer on the same day?
Yes. Close your eyes because the images are devastating for your hair.If you want to venture into bleaching your hair twice with a 30-volume developer, you should wait at least three weeks between the first and second bleaching session. Here’s why.
Why should you wait three weeks to bleach your hair with a 30-volume developer between the first and second session
Our hair is made up of several layers, such as the hair cuticles, the hair fiber, and the core. They protect it from aggressive external factors such as the sun’s rays, smog, or, cold.
These layers prevent your hair from losing moisture, nutrients, and color unless you expose your hair to the sun’s rays every day, for a long time, without protection.
But, when you bleach your hair, the bleach aggressively enters your hair core, washes away color, nutrients, and moisture. Once bleach enters your hair, side effects can be unpredictable in inexperienced hands.
Tell me the truth, before bleaching your hair, did you perform the strand test? And if you haven’t bleached it yet, were you planning to do it?
I’m guessing you don’t even know what the strand test is. But it’s never too late to learn a new one.
The strand test consists of separating a small back strand of your mane, applying the bleaching mixture, and evaluating how your hair reacts.
If your hair doesn’t break, it will withstand the process. Even salons use the strand test before bleaching hair.
Let’s go back to the first bleaching. When you apply the bleach, the 30-volume developer opens the cuticles, and the outermost part of your hair that prevents your hair from frizz.
As the bleach penetrates the hair fiber, your hair begins to lighten and lose nutrients and moisture. When it reaches the core, it removes as much color as possible.
When the exposure time is over and you rinse the mixture out, your hair will have been stripped of color, nutrients, and moisture. Also, most cuticles will be broken.
So, after bleaching your hair once, the result will be drier, more brittle, and weakened hair.
Can you imagine what can happen if you bleach your hair twice with the 30 volume developer on the same day?
Therefore, leave three or four weeks between the first and second bleaching. In the meantime, moisturize and repair your hair with natural oil or keratin masks.
Now I’ll ask you a question:
Why do you want to bleach your hair twice with 30 volume developer?
I guess the answer is that your hair is very dark and you want to go blonde faster. In this case, you have two ways to go.
The first is to bleach your hair with a 30 developer and wait three weeks to bleach it again. I’ll tell you about the second way.
If you want to lighten your hair faster, go to a salon and invest in Olaplex or Wellaplex
These two products have several steps and must be applied by professionals because they are integrated into the bleaching mixture.
This is the only way to bleach your hair to lighter blondes faster without irreversibly ruining your hair.
But I have to be honest. Both Olaplex and Wellaplex make the bleaching process very expensive. So, you’ll have to balance your possibilities and your desires.
But what you can’t leave to chance is the health of your hair.
You cannot bleach your hair twice with a 30-volume developer on the same day. There should always be three weeks between the first and second bleaching.
You can use Olaplex 3 or natural oil masks to repair your hair between the two sessions.
