What color does blue hair dye fade to? How to keep the color from fading?

faded hair color

  • When your blue hair starts to fade, your hair will begin to take on a greenish color.
  • To ensure that your color lasts for longer, you can wash your hair with blue shampoo. Each time that you apply it, you’ll be adding blue pigmentation. In this way, your hair will maintain its color for more time.
  • But no matter how many precautions you take, eventually your hair will lose its color. At that moment, you’ll need to apply your chosen dye again.

 

Blue tones are normally sold as semi-permanent dyes.

If you want to apply a blue color to your hair with a permanent dye, you should use another color with blue undertones, for example:

  • Blue black 1.8
  • Blue brown 2.8

No permanent dyes are a pure blue color.

 

All that said, now I’ll let you in on more facts and tips about blue hair that surely will be of interest to you.

What color will my blue hair look like when it fades?

after eight washes

As I was telling you at the beginning of this article, when the blue color fades, it leaves behind a bluish, greenish tone.

Do you know why?

 

When you apply a semi-permanent dye, you should bleach your hair until it’s a light blonde color.

This is because semi-permanent dye doesn’t contain ammonia nor does it have bleach.

With the blonde base color, when you apply a blue dye, and it fades, you’ll end up with greenish hues.

Yellow and blue make green.

 

I’m not saying this to scare you.

Semi-permanent dye breaks down with each washing, so you’ll notice that your color gradually changes.

But don’t worry, there any many ways to avoid that your blue color fades quickly.

 

How to prevent that your blue color fades?

All dyes have a lifespan — semi-permanent dyes last for 6 to 8 washes.

This is because they don’t contain any chemicals that would make the pigmentation penetrate the hair fibers.

In this way, you don’t damage your hair, and you can change your color as often as you want.

But that said, the color’s duration will be limited.

 

Blue shampoo contains pigments that make it so that with each application, your hair will absorb color.

You should go to a salon store or pharmacy and ask for blue shampoo.

Use it each time you wash your hair.

 

 Even if your hair will still fade little by little, the shampoo will allow you to maintain the color for up to 10 to 12 washes. 

It’s an easy tip for semi-permanent dyes!

 

  • Another useful tip to keep your hair’s perfect blue tone is that you shouldn’t use hydrating masks under any circumstances.

Hydrating masks contain chemicals that strip pigment from hair.

 

 Instead, you can apply coconut or argan oil to moisturize your hair. A few drops applied from the roots to the tips, and your hair will be good as new in a few days. 

And the best part? You don’t even need to rinse it out.

 

You can apply these oils once per week.

If you carefully follow this advice, your blue tone will last for longer, and it will always look shiny and new, as if it was recently dyed.

 

What to do when your blue hair finally fades?

When the greenish-blue tones I told you about at the beginning have appeared, you should redo your color.

Because it’s a semi-permanent dye, you can apply the same blue shade or a shade of blue that’s lighter or darker.

 

 You can also put in another tone of semi-permanent dye, as long as you choose colors that aren’t extremely light, such as light pink or silver-gray. 

Semi-permanent dyes don’t require bleaching of your hair for color changes — you just need to put in a new tone that you’ve chosen and that’s it. You’ll have your new look without any complications.

 

If you decide to stay with the same blue shade, I’ll let you know that the color renewal should be from roots to tips, and because it’s a semi-permanent dye, you can play with your look as much as you want.

You should keep in mind the growth of your hair roots.

  • If you like your roots darker, you should just apply the blue dye.
  • If you choose to leave your roots darker, I would recommend a midnight or navy blue that’ll show up well with dark roots.
  • Now, if you don’t want to leave your roots dark, you should bleach the new hair growth.
  • As I said before, the semi-permanent dye doesn’t contain ammonia nor bleach, so if you don’t bleach your hair, the blue dye won’t cover up your roots very much.
  • It’s for this reason that you should bleach.
  • Once you’ve bleached your roots, you can apply whichever blue tone that you’ve chosen.

I recommend that you redo your color from roots to tips at once, so you do it all in the same day.

Do you know why?

 

 The semi-permanent dye fades much more quickly than permanent dye. 

In this way, if you apply the dye to your roots one day and to the rest of your hair another day, you’ll notice the difference between the tones quickly.

For example:

If on a Saturday you put blue semi-permanent dye in your roots, and you wait until the next Saturday for the rest of your hair, during the week you’ll have washed your hair at least two times.

This will make it so the long part of your hair is more faded than the roots, which will have more pigment.

You’ll have a band of very intense blue color.

It won’t look very pretty!

 

So my recommendation is that you reserve a day in your schedule for completely redoing your blue color so it will look perfect.

 

What happens if I want a color change?

If you’re tired of your blue color and you want to change your hair you can do it without a problem.

It’s the truth, semi-permanent dyes are applied to bleached hair so it isn’t necessary to bleach it again.

 If you choose another semi-permanent dye, as long as it isn’t light pink or pearl gray, you can put in any color you want. 

You just need to pick the tone and apply it.

 

The semi-permanent dye is applied with damp hair, and should be left in for 40 minutes.

You can choose colors like fuchsia, turquoise, orange, or even the latest trends of fluorescent colors like green and yellow.

 

However, if you’re looking for more conventional colors, you’ll need to put in permanent dye of the color that you choose.

 If we’re talking about permanent dyes you can choose any light color without a problem. 

Do you know why?

 

Permanent dyes contain ammonia and bleach — these chemicals make it so your hair absorbs the pigment.

Thanks to this, whatever remains of your semi-permanent dye will disappear once you apply the new tone.

  • So you can put in a platinum blonde 10 or blonde 8 without any problem.
  • You can also go with a darker tone like brown 4 or chocolate 5.

It all depends on the look that you want to have.
