Are you considering using purple shampoo on your blue hair?
- Purple shampoo won’t have any effect on your blue hair. By saying that, I mean that it won’t damage your color, but it also won’t change it.
- So, if you want to strengthen the blue color in your hair, you should use a blue shampoo.
- And, if you want to get a more purple color in your hair, you should dye it purple once your blue has faded, or gradually change the color by using a red shampoo. I’ll tell you about that last option in a moment.
That’s because purple shampoo was designed with a different purpose in mind.
Do you know what the purpose is?
To neutralize unwanted yellow tones that tend to appear as time passes in hair that’s been dyed blonde.
That’s why when it comes to blue hair, purple shampoo won’t have any effect.
The question I need to ask you, then, is: What do you want to do to your blue hair?
There are two possibilities.
- Are you hoping to brighten up the blue in your hair?
If you love your blue hair, it makes sense that you want to do this because that vibrant blue you love will fade with time. If so, there are products out there that will help brighten and intensify your color.But purple shampoo is not among those products. The right product would be blue shampoo.
- Are you tired of blue and you want to change your hair color to a purple color?
In this case, purple shampoo is not the solution you’re looking for because it doesn’t contain the necessary pigments to change hair color completely.
So, what you’ll need to do instead is let the blue completely disappear and then dye your hair with purple dye.
Toning shampoos can help you lengthen your color’s life, but you need to use the shampoo correctly.
That’s why, if you want to brighten up your blue or make the transition from blue to purple, stick around, because I’ll tell you:

How to choose the right shampoo for hair that’s dyed blue
Like I said initially, purple shampoo works to neutralize yellow colors after you bleach your hair or maintain an ashy tone in dyed blonde hair.
That’s why if you have blue hair, it isn’t going to do anything for you. It won’t have any effect on your hair. There won’t be a negative effect because it won’t ruin your color. But it won’t be a positive effect either, because it won’t improve your blue.
You probably thought that it could affect your blue hair since purple is a mix of blue and red.
Unfortunately, the number of blue pigments that there are in purple shampoo won’t be enough to change your blue hair to purple, nor are they enough to help brighten up your color.
Your hair will stay looking fantastic for longer, without needing to touch up your dye so often.
So, now you know that you should use blue shampoo to keep your blue color brighter for longer.
But, and I’m not trying to make things complicated, you should use a blue shampoo that matches your hair color.
Because, after all, the colors of semi-permanent blue dyes aren’t all the same. You can dye your hair a midnight blue, a French blue, a light blue, or an electric blue.
The brands of semi-permanent dyes that carry these kinds of bright colors typically have a line of toning shampoos and conditioners that can be grouped into three colors:
- Dark blue
- Medium blue
- Light blue
That’s why you need to keep in mind your hair color to choose the correct color, blue shampoo.
- If your hair is midnight blue or navy blue, you should use dark blue shampoo.
- If your hair is French blue or simply blue, you should use medium blue shampoo.
- If your hair is light blue, electric blue, or sapphire blue, you should use light blue shampoo.
So, now we’ve covered the first question: how to brighten up the color of hair that’s dyed blue.
But, what happens if you want to go from blue hair to purple hair? We’re almost there – that’s what I’m about to tell you about.
How to make the transition from blue hair to purple hair
If you’re considering changing your hair color from blue to purple, it’s a very different story. And you can choose between two different options to make this change:
- Wait until the blue dye fades, and use a purple dye on your hair
- Gradually change your color by washing your hair with red shampoo
Let’s take a look at each option in a little more depth.
Use purple dye when the blue color in your hair has disappeared
The best time to do this is when you’d normally touch up your color.
As you surely already know, semi-permanent dye lasts about 2-3 weeks. And then, at the point, instead of using the same blue color on your hair as you normally would, you can choose the purple that you like best and use that on your hair.
The good thing about this transition is that you won’t need to bleach your hair because you don’t need a light base to use these kinds of colors. Remember that if you used a semi-permanent dye last time, you should use a semi-permanent dye again this time.
Gradually change from blue to purple
Do you remember what colors purple is made up of?
I see that you’re paying attention because you probably said that purple is made by mixing two colors: blue and red.
That’s why, if you wash your hair with red shampoo, you’ll have both of the colors needed to make purple, and you’ll see that gradually, each time you use the red shampoo, your hair will look more and more purple.
What red shampoo should you use to go from blue to purple?
- If you want a darker purple, you should use a dark red shampoo.
- If you want a medium purple, you should use a medium red shampoo.
- If you want a lighter purple, you should use a light red shampoo.
Now I’ll ask you the last question on this exam:
Which shampoo should you use once you have purple hair?
Blue, red or purple?
Excellent! You should use purple shampoo to brighten your new color.
- If you have blue hair, you should use blue shampoo to brighten it.
- If what you’re trying to do is go from blue to purple, you’ll have two options: wait for the blue to fade and use a purple dye. Or, wash your hair with red shampoo to make your hair gradually turn purple.
Now that we’ve gotten to the end of the rainbow, what color will you end up within your hair when this is all over?
