What’s the good news?

That  if you bleached your hair and you use a permanent dye, the color will stick much faster and will be much more intense than if you used it on hair that hasn’t been bleached. 



Your hair probably feels straw-like after bleaching it, because it lost vitamins, minerals and moisture, essential elements for having healthy hair.

Because of that, your hair is completely dehydrated and “thirsty,” which means that anything you use on it, it will absorb.


And that’s good news.

Now, that doesn’t mean your work is done.

To make the dye last in your bleached hair four to six weeks, you need to up the ante on your hair care routine.

  • If you take care of your bleached and dyed hair,  the permanent dye will last six weeks. 
  • If you just go about your normal routine, using any old product on your bleached and dyed hair,  the dye will last four weeks. 

Now what do we mean when we’re talking about how long permanent dye will last on bleached hair?


At this point, I’d like to clarify one thing.

  •  If you’re talking about how long the dye lasts in your hair, period, , ti’s going to last until your hair grows out and your natural color appears from your roots.
  •  If you’re talkinga bout the intensity of the color of the permanent dye , it will last between four and six weeks.


Because permanent dye doesn’t disappear as you wash it, like what happens with semi-permanent dyes. What does happen is that the color  loses its intensity. 


So, which side are you on?

How to make permanent dye last longer in bleached hair

use of permanent dye after bleaching

Let me ask you a question:

Do you know what a grimoire is?


Well, grimoires were spellbooks, usually written during the Middle Ages. To tell you the truth, I think they were books more about pagan rituals than what people think of as magic.

But that’s another story.

Why am I asking you about grimoires?


Because if you want to make your permanent dye last longer in your bleached hair, I’m not going to give you any ancient magic spells or hexes that you need to perform under the glow of a full moon.


 Caring for permanent dye in bleached hair just takes a few almost basic principles  that you might even already be familiar with.


But since I’m more of an alchemist than a witch, I’ll give you the secret (or, not-so-secret) formula. So, pay attention and forget about bat wings and frog feet because you won’t need them.


Wash your hair up to three times a week to make permanent dye last longer in bleached hair

how often to wash bleached and colored hair

That simple action will make  the color of your dye stay more intense for up to six weeks  and it will also help protect your hair.


Yes, washing your hair more than four times a week is really a crazy idea because all that’s going to accomplish is drying out its natural moisture.

Your scalp expels natural moisture that maintains the nutrients in your hair’s roots. But every time you wash your hair, those nutrients disappear and not magically. The fault lies with shampoo and water.

If you wash your hair up to three times a week, the color will last longer and that will help stop your hair from weakening and breaking.


Use cool to cold water to wash your hair

 The ideal temperature for washing your hair, especially for bleached and dyed hair, is room temperature. 

Want a magical secret?


Regulate the water temperature until it feels warm on your body and cold on your head. That way you’ll be able to hydrate and clean your hair without ruining the color of the dye.

Warm water opens your hair cuticles so your dyed hair will lose its intensity quickly in hot water.


Wash your dyed and bleached hair with sulfate-free products

after coloring hair

I understand it’s a hard time economically for most people and that a lot of supermarkets tempt you with discounts, like “two for the price of one.”


But, think about it for a minute.

You may very well have spent a fortune bleaching your hair, and you also took on a good deal of risk because bleaching your hair is an aggressive chemical process for your hair.


If you’ve been through all that, isn’t it a good time to give your hair a little love?

I’m not saying that you need to go out and buy the same shampoo the Kardashians use, which probably is one of the most expensive ones out there.


But  you should at least invest in sulfate-free shampoos, conditioners and hair masks. 

That’s the minimum you should do for your hair; it’s not optional.


Sulfates are the worst enemy of bleached and dyed hair, and that’s why using products that don’t contain them is the best thing you can do to maintain your dyed hair.

  • Because they make your colored hair lose its intensity.
  • Because they dry out your hair, since sulfates are detergents.
