Can I use Crazy Color on my dark hair, or should I bleach it first?

on black or brown hair

For months, I only wanted one thing: to try out Crazy Color hair dye.

I wanted to become one of those carefree girls with vibrant hair, who looked like they didn’t care what anyone thought.


The idea slowly became an obsession that filled my mind, until I couldn’t think of anything else.

But although I wanted nothing more then to try a Crazy Color dye on my hair, I wasn’t sure if the dye would work on my deep brown hair, or if I would have to bleach it first.


Caught up in the excitement, I decided to take the leap and dyed my hair with a beautiful purple. Are you curious about how it turned out? If you are, keep reading!

But first, let me be straight with you.

  • Using Crazy Color on dark hair is simply a waste of money. I can tell you from experience that it won’t change the color at all.
  • Simply put, dark hair has to be bleached to before you can use any of the brand’s fantastic fantasy colors.


As they say where I’m from, I had to learn that the hard way.

The first time I ventured to try Crazy Color dye, I picked out a shade of divinely deep indigo.

  • I followed the instructions on the box to the letter.
  • But as the dye processed, I didn’t see the color change at all. Ten minutes later, and it was exactly the same.
  • Twenty desperate minutes later, there was still no change. After forty minutes, I was ready to cry from frustration.
  • Finally, I rinsed out the dye and dried my hair with a towel, I took a look in the mirror… only to discover that my hair was the same shade of dark brown.

What went wrong? Hundreds of Instagram influencers have used Crazy Color to create wildly colorful hair… why couldn’t I?


After I bit of research, I discovered getting those vibrant colors takes a bit more work than the smiling Instagram models let on.

If you have dark hair and want to get a good result with a vibrant Crazy Color hair dye, you’ll have to bleach it first.


 Not only that, but depending on your natural hair color, and the color you want, you may need to bleach it more than once. 

Are you curious why?

I’m going to be straight with you. When I learned that I would have to bleach my hair to get the color I wanted, I was terrified.

I had heard horror stories about bleach jobs gone bad, and I’ll admit I let my imagination run wild thinking about clutching strands of my horribly damaged hair, injuring my scalp, or even going bald.

But I shouldn’t have worried: today, hair bleaching is completely safe. And even safer if you get your hair bleached with a qualified professional, which I did.


Crazy Color hair dye works great on blond hair, and the lighter it is the better. It’s just like watercolors. If you paint on white paper, the colors stand out, bright and crisp.

Now imagine trying to paint with watercolors on black paper. It’s going to be hard, if not impossible, to see the colors.


 Well, hair works the same way. To achieve the color you want, you have to first strip the existing pigment from your so they the dye can deposit another color. 

The closer your hair is too blond, or even white, the easier is it for the dye to work.

Just like watercolors.


  • If you want to dye your hair a pastel shade, you might even have to bleach your hair twice.
  • But if you’ve chosen a darker fantasy color, bleaching it once should be enough.


To dye my hair purple, I only had to bleach it once. My stylist also used Olaplex, a product that protects the hair while being bleached.

Using Olaplex made it possible to bleach and dye my hair on the same day.

Are you curious how much my purple hair cost?


 Well, they say health is priceless, and I include care hair in health. All I can say is it was worth every penny. 

Because my hair looked absolutely amazing with its new Crazy Color.  And it didn't look or feel damaged.


If you're not sure if you want to go to a professional, consider this. Fantasy colors, such as those offered by Crazy Color, can have unexpected results if your hair was not bleached properly.

What does this mean?


When you dye your hair, the resulting color doesn't just come from the dye, but rather how it blends with your base hair color. For example, if you blue hair dye on a deep brown, you run the risk of it turning out red or purple instead of the desired color.

Now, we have one more question to discuss: is it possible to get a successful result with Crazy Color on unbleached hair?


But first, let's talk about how to bleach your hair at home if you're determined to DIY it.

As it said, it's always best to find a qualified professional to bleach your hair.

But if you're daring, you can also bleach your own hair at home.

Before bleaching your hair, it's important to note that you should only bleach healthy hair. Bleaching, after all, is an aggressive chemical process.


  • I recommend buying a bleaching kit, which has detailed instructions you can follow to minimize the chance of mistakes.
  • Always use gloves.
  • And bleach a test strand first, just to make sure you don’t have an allergy or any adverse reactions to the product. After that, you can divide your hair into sections so it’s easier to work with, mix the products and apply it to your hair.
  • After you’ve applied the bleach to all your hair, wait half an hour, and rinse.


It's best to wait two days before using Crazy Color dye on your newly bleached hair, and use a deep hydrating treatment the day before you dye your hair.

This protects your hair and helps restore some of the moisture it lost while being bleached.

Are you still unsure if you want to bleach your hair?


As I mentioned, there is an alternative. Let's discuss it in depth.


Is it possible to get a successful result with Crazy Color on unbleached hair?

The short answer is yes, but with some limitations.

Some colors are simply not possible without bleaching your hair, such as pale pink, emerald green, or sky blue, pastel hair colors, or mermaid hair.


If you have dark hair and are determined to dye it without bleach, you'll have to choose a dark shade, nowhere near a pastel.

But, as I said, you won't be able to get an intense color, much less trending styles like rainbow or unicorn hair.

But it is a fun and less risky way to experiment with a new color.



And there you have it.

  • None of Crazy Color’s more popular bright colors will work on dark brown or black hair.
  • Neither the Burgundy, nor the Ruby Rouge, nor the Sky blue, will show up on dark hair that has not been bleached.


Crazy colors are super fun, but you need to be ready to care for your hair after dying it.

Once you have your perfect vibrant shade, remember to use shampoos and conditioners formulated for dyed hair, and get use deep hydrating treatments at least once a week.


Now that you know how to transform your hair into any color of the rainbow, what shade of Crazy Color are you dreaming of?
