Bleaching your hair is a process that can lighten your hair color by removing the natural pigment. There are a few different ways to bleach your hair, but the most common is to use a bleach powder and developer. How long you should leave the bleach in your hair depends on your hair type, the color you are trying to achieve, and the strength of the bleach.
If you are trying to lighten your hair by more than two shades, you will need to use a stronger bleach and leave it in for a longer period of time.

Should I bleach my hair dry or wet?
Bleaching your hair can be a great way to achieve a light, bright, and blond look. However, there are a few things you should consider before bleaching your hair, including whether you should bleach your hair dry or wet.
Bleaching your hair dry is the most common way to bleach your hair. When you bleach your hair dry, you apply the bleach to your hair and then wait for it to work. This process can take a while, and it can be difficult to judge how long you should wait. If you bleach your hair dry and leave the bleach on your hair for too long, you could end up with damaged hair.
Bleaching your hair wet is another option. When you bleach your hair wet, you apply the bleach to your hair and then rinse it off. This process is faster than bleaching your hair dry, and it is easier to judge how long you should wait. If you bleach your hair wet and leave the bleach on your hair for too long, you could end up with damaged hair.
So, which is better – bleaching your hair dry or wet?
Ultimately, whether you bleach your hair dry or wet is up to you. However, bleaching your hair wet is generally safer and it is easier to achieve the desired results.
Should I use 20 or 30 Developer bleach?
When it comes to developer bleach, there are a lot of different opinions on what strength to use. 20 developer bleach is a popular choice, but some people argue that 30 developer bleach is a better option. So, which is the right choice for you?
The main difference between 20 and 30 developer bleach is the strength. 20 developer bleach is weaker, which makes it a good choice for people with sensitive hair. 30 developer bleach is stronger, so it is better for people with resistant hair.
If you have resistant hair, then you should use 30 developer bleach. It will help to break down the proteins that make your hair resistant, and it will also lighten your hair more quickly. If you have sensitive hair, then you should use 20 developer bleach. It is weaker, so it will be less likely to damage your hair.
Ultimately, the choice is up to you. If you are unsure which strength to use, then start with 20 developer bleach. If it doesn’t lighten your hair enough, then you can switch to 30 developer bleach.
