Dry shampoo makes my hair greasy, what can I do?

If dry shampoo made your hair greasier, there could be two reasons.

  • The first is that your hair needs more moisture. Your hair was dry and damaged before using the dry shampoo. Then, using the shampoo worsen the situation. In this case, you should stop using dry shampoo.
  • The second reason is that you’re not using dry shampoo properly. So, the dust from the dry shampoo generates more greasiness. I’ll tell you how to prevent this later on.

One of the things I hear the most in the salon is my clients complaining that a certain treatment or product ruined their hair.

And what they rarely stop to think about  is whether it was actually the treatment or the product that ruined their hair, or if their hair was already damaged before. 


In other words, if you apply permanent dye to your dry hair, it’ll be even drier after coloring. The dye contains ammonia and is applied with a developer. So, it strips the hair of moisture.

But obviously, your hair was ruined before you colored it, and the dye just worsened the situation.


In the case of dry shampoo, something similar happens.

It all comes down to two things.

 Either you’re using dry shampoo wrong or the excessive sebum production on your scalp was a pre-existing condition. 


You should understand that if your scalp is producing twice as much oil, your mane isn’t healthy.

Why is that?


There can be different reasons.

  • Maybe you bleached your hair and didn’t repair it after the process.
  • Alternatively, you dye your hair too often.
  • Or you simply abuse heat tools and don’t use a heat protectant.


In that case, when the hair is seriously damaged, the scalp produces more sebum to try to repair the damage.

So, dry shampoo has nothing to do with the fact that your hair is greasier.

The same thing will happen if you use dry shampoo incorrectly. And I’ll tell you more about that later.

Now, let’s start with the first point.

If your hair was damaged before using dry shampoo, you should stop using it and repair it

In that case, your hair lacks moisture.

What happens when hair lacks moisture?

 The scalp starts to generate more sebum in an attempt to repair your hair.  That is exactly its function as the scalp is the natural source of moisture in your hair.

Your scalp has tiny spaces where hair follicles are located. Hair is generated inside of them.


Your head is exposed to heat in summer and cold in winter. That exposes the scalp to many aggressive factors.

The scalp maintains hydration because the hair acquires nutrients that keep your hair healthy from root to tip.


This is what happens in healthy hair.

What happens to that natural moisture when hair is damaged, either by bleaching, coloring, or heat tool abuse?


Your scalp will try to repair your hair by producing more oil.

 If you add dry shampooing to this situation, your hair will be oilier. 



Because dry shampoo is designed to remove this oil. Therefore, your scalp will try to produce more moisture. So, it’ll produce more oil.

 But it’s not the dry shampoo that produces it. It’s your scalp trying to repair your hair. 


How do you break this vicious cycle?

  • First, you should stop using dry shampoo.
  • Second,  start a deep hydration treatment  using masks with keratin and hydrolyzed protein.
  • Third, wash your hair the usual way, i.e. with water and sulfate-free shampoo two or three times a week.


When your hair is repaired and free of dryness, you can use dry shampoo again.

Remember  that you should use dry shampoo no more than twice a week and never more than two days in a row. 

Isn’t your hair damaged, and you feel that dry shampoo makes it greasier?

I can only think of one reason why this may be happening.

If you use dry shampoo incorrectly, it could produce more scalp oil

What do I mean by using shampoo incorrectly?

I mean that you can make some mistakes during its application. Let’s look at each of them in detail.


  • You don’t let the dry shampoo act long enough

There are different brands of dry shampoo. Some recommend leaving it on for five minutes, and others recommend leaving it on for ten minutes.

My recommendation is to  leave it on for five minutes longer than the manufacturer indicates  to make sure to remove the grease.


  • You apply the shampoo too close to your scalp

You should always spray the dry shampoo at a distance of 30 centimeters from the scalp. This way, you make sure to distribute it evenly.


  • Don’t brush your hair before and after shampooing

All dry shampoos deposit dust on the scalp that has to be removed. If you don’t brush it out from roots to ends, your hair will be greasier.

So, to prevent dry shampoo from making your hair greasier here’s how to use it correctly.

  • Brush your hair from roots to ends.
  • Shake the dry shampoo bottle and start applying in small sections, separating the hair at each stroke. Remember to keep a distance of 30 centimeters.
  • When you have covered your scalp,  leave the dry shampoo to act for five minutes longer than the time indicated by the manufacturer. 
  • Then, massage your scalp with your fingertips and shake your hair with your hands so that the powder doesn’t adhere.
  • Finally, brush your hair to remove any remaining powder.



If you notice that your hair is greasier after using dry shampoo, you may not be using it properly, or your hair may be damaged.

Check the way you use it, and remember that you should brush your hair before and after shampooing.

If your hair was damaged before you started using dry shampoo, you should stop using it and repair your hair first.
