There are three reasons why your hair has gone gray instead of blonde:

  • You used the toning shampoo for too long or you used it too often. In that case, wash your hair with hot water and a sulfate shampoo to remove the excess pigments.
  • You applied an ashy toner and your hair hasn’t expelled the excess toner. In this case, you can wait for it to fade with washes. Alternatively, you can fix your hair color by using an anti-dandruff shampoo.
  • You applied an extra ashy hair dye. In this case, as the dye is permanent, you’ll need to use a color remover.

I don’t want to mislead you.   The solutions I just mentioned to fix hair that turned gray instead of blonde are easy,   but they depend on your hair health and coloring experience.

Let’s be honest. If your hair has turned gray instead of blonde, there’s probably something wrong in the process. Can you go wrong once?


Of course, you can get it wrong. But we’re not talking about making a mistake when choosing a color to paint a picture on a piece of paper.

In that case, the worst would be to throw away the drawing and the sheet of paper.


In turn, this is about your hair. Think of your hair as any other part of your body. Your hair feels and suffers. It moisturizes and dries out. Would you do strange experiments with the skin on your hand?

Would you try reapplying a cream that irritated your face the first time?

I think the answer would be negative.

In this case,   my advice is that if your blonde hair turned gray because you left the toner on too long or used the toning shampoo too often,   you should wash your hair once to remove the excess purple pigments.

How to fix hair that’s gone gray instead of blonde

To remove the excess gray and get your hair back to blonde, you need to know the cause of the color change in your hair.


If your hair has turned gray instead of blonde because of the toning shampoo, wash your hair with warm to hot water and a sulfate shampoo.

Although purple shampoo pigments fade when you stop shampooing, you should wash your hair with hot water to remove them immediately.

  Let the hot water run for three to five minutes   and wash your hair with a shampoo with sulfates. Generally, the cheaper shampoos contain sulfates, detergents that fade artificial hair color.

Remember also to apply a conditioner to moisturize your hair.


If your hair turned gray instead of blonde after toner application, use a clarifying shampoo or an anti-dandruff shampoo.

In this case, you’ll need to use a stronger product than the sulfate shampoo because the toner contains ammonia and settles in the hair core.

That is why I recommend you wash your hair with an anti-dandruff shampoo or clarifying shampoo
and leave it on for ten minutes.

  If your hair is still grayish after applying the anti-dandruff shampoo,   wait two days and repeat with the anti-dandruff or clarifying shampoo to fix your over-toned hair.

Remember to moisturize your hair with conditioner and if possible, apply a keratin mask to repair your ends.


If your hair turned gray instead of blonde after applying an ashy dye, you can use a color remover

Let’s analyze this. You used a dye that contains ammonia and is applied with a developer, and you didn’t get the color you wanted.   Are you willing to risk using a color remover and ruining your hair color and health?  


A professional should only do color correction. The colorist will assess your hair health and know which path is best to fix your hair color.

Although all roads may lead to the same solution, some are more dangerous. Many people claim that a color remover is easy to apply, but the truth is that it breaks the molecular bonds of the artificial color in the hair core.

Obviously, during this process, your hair will lose nutrients. Visit a professional and finally have healthy blonde hair.



Your hair may have gone gray instead of blonde because coloring can leave excess pigment. Products like toning shampoo, ash toner, or ash blonde dye contain pigments. Now you know how to fix it, but as a colorist, I advise you to visit a salon as your first choice to fix your hair color.
