Most people will agree that if you want to bleach your hair, you shouldn’t be washing it for a few days beforehand. This will help to ensure that you have a protected layer of oils on your scalp.

Of course, this does have people wondering whether they can use dry shampoo instead. They seem to believe that this will keep their hair clean, but they won’t have to hop into a shower where those natural oils could be washed away. So, will dry shampoo affect bleach? Let’s take a look.

Will Dry Shampoo Affect Bleach?

Yes. You should not use dry shampoo on your air if you are planning on bleaching it. In fact, you should have as little product in your hair as possible. The more product you have in your hair, the less chance you have of the color sticking. In fact, if you have dry shampoo in your hair when you bleach it, then there is a good chance that you will end up getting the completely wrong color. 

The main reason why you shouldn’t have dry shampoo in your hair before you bleach is down to the fact that dry shampoo is corrosive. Bleach is also corrosive. When these two combine, they are going to seriously damage your hair. In fact, in most cases, you should avoid using the products on their own. You certainly shouldn’t be using them together.

In addition to this, the dry shampoo may act as a sort of protective layer on your hair. This can prevent the bleach from properly sticking to the various strands of hair. This could potentially leave some areas of your head uncolored. Although, in most cases, you may end up with a slightly different color from what you would expect. Your hair will still look bleached, but some parts of your head may end up darker than others.

A lot of people who bleach their hair often find that the texture of their hair changes when they have dry shampoo in it. This can make it slightly more difficult to carry out the bleaching process. When you have dry shampoo in your hair, the hair has an almost powdery quality to it, and it really doesn’t feel all that pleasant to the touch. It feels rough, and you may end up messing up the coloring process because of this. 

If that wasn’t enough, dry shampoo actually sucks up all the grease on your scalp. This is going to be a huge issue. When you are bleaching your head, you need to ensure that your scalp is protected, otherwise, you could end up with chemical burns. The dry shampoo is, effectively, taking away exactly what you need to ensure that you do not end up with a rather painful scalp. 

Does Dry Shampoo Affect Colored Hair?

This will be dependent on when you use the dry shampoo. If you are using it before you dye your hair, then it will stop the dye from sticking to your hair. However, if you use dry shampoo after you dry your hair, then there shouldn’t be any impact.

It is important that you do not have any dry shampoo on your hair before you dye your hair. While there is a chance that it will not have any impact on the dying process, many people do note that in most cases, it will stop the dye from properly sticking to the hair strands. This means that the color may end up being a bit lighter than you expected it to be.

If you use the dry shampoo after the hair coloring has dried, then there should be no impact. Some people find that the hair loses a little bit of its shine. However, to be honest with you, this is something that is going to happen when you wash your hair anyway, so don’t avoid using dry shampoo. 

Should Your Hair Be Dirty Or Clean When You Bleach It?

Your hair should be dirty before you bleach your hair. It doesn’t have to be completely dirty, but you should avoid washing your hair for 72 hours before the bleaching process. It will provide a little bit more protection for your scalp. 

When you wash your hair, you aren’t just washing away the dirt and grime that has built up over time. You are also washing away the hair’s natural oils. 

While these natural oils do a few different jobs on your head, one of the main jobs is to protect the scalp. This can come in incredibly handy when you are bleaching your hair.

Obviously, bleach is a pretty strong chemical. If you bleach your hair without protection for your scalp, then there is a pretty good chance that you will end up irritating your scalp, and that is not going to be pleasant in the slightest.

Don’t worry. Once you have completed the bleaching process, there should be no issues when it comes to washing your hair. So, if you aren’t a fan of all that grease build-up (you may not be if you have naturally greasy hair), you will be washing it away pretty quickly after you have bleached your hair.

If you have washed your hair recently, then we suggest that you avoid using bleach. However, if bleaching is a priority for you, then you can use coconut oil to protect the scalp instead. 


Dry shampoo will impact the bleaching process, so you should avoid it as much as possible. You certainly shouldn’t be using it in the three days before you bleach your hair. In fact, you should be avoiding using any product in your hair for a few days before the bleaching process.

Once you have colored or bleached your hair, then there should be no issues with using the dry shampoo. However, do bear in mind that you may discover that the hair ends up losing its glossy look when you do this. If you can, try to look for products aimed at those with colored hair.
