Can You Mix Blue And Purple Shampoo?

Among neutralizing shampoos, blue and purple shampoos are the most well-known. The former cancels out orange, red, and copper tones, while the latter gets rid of yellow and brassy tones. But what if your hair needs the functions of both? 

In that case, can you mix blue and purple shampoo? 

If you are curious to find out, keep reading, and make sure that you reach the very end. We will tell you the answer to, “Can you use blue and purple shampoo at the same time?” and “What happens if you mix blue and purple shampoo?” too. 

Can You Mix Blue And Purple Shampoo?

No, do not do this. 

Mixing blue shampoo and purple shampoo will give you a blueish violet product that will simply do a substandard job of neutralizing your unwanted tones. 

Blue shampoo cancels out orange tones because orange is opposite to blue on the color wheel. So, for example, when you lift your hair to a medium blonde to light brown, your hair will oxygenate and become orangey or coppery, you would want to fix it with a blue shampo. 

Purple shampoo cancels out yellow tones because yellow sits opposite to purple on the color wheel. When you color your hair platinum or light blonde, then your hair strands will fade into yellow or pale yellow, and you would correct it using a purple shampoo. 

When you mix the shampoos, both the blue and purple’s correcting effects are now no longer as strong. They cannot as effectively cancel out the tones that they are supposed to based on the Color Theory. They would work a lot better on their own and with their original formula and designated shade. 

Moreover, if you do not mix them well enough, the results can be patchy and uneven. As a result, you will have even more problems on top of the ones that you already have with unwanted tones. Uneven and patchy colors are incredibly difficult to correct. 

And the color shades will no longer be clearly yellow or orange, so it is difficult to find a solution that is effective. 

Can I Use Blue and Purple Shampoo Together? 

Yes, you can have both blue shampoo and purple shampoo in your hair regime. 

You can alternate between blue shampoo and purple shampoo so they can each do their job and help you get rid of unwanted tones. Or you can use them both in a single shower or wash. But note that you should never mix them together in a single bottle. 

That being said, here are the two cases: 

Case 1: There are integrated highlights or orange and yellow undertones throughout 

In this case, you should alternate between blue shampoo and purple shampoo. If your hair has more yellow tones than orange tones, for example, you can use purple shampoo and regular shampoo. Then, in the next week, you use switch purple with blue shampoo.

You should not use them both during one shower or wash because this can lead to fried ends and a lot of frizziness. Your hair will also become extremely vulnerable to damage. 

With this said, you should limit your use to just once a week. Only when you notice that there are no negative reactions, should you use it this way 2 to 3 times a week. 

Case 2: There are clearly defined areas that are too orange or too yellow

For example, when your roots are orange and your lengths’ ends are yellow. You can use both blue and purple shampoo during the same shower/wash. For this situation, you can apply blue shampoo to the roots and purple shampoo to the lengths’ ends.

Here are all the specific steps that you need to take: 

  1. Wet your hair with warm water. 
  2. Pat dry it slightly using a towel, making sure that it is damp but not soaked. 
  3. Lather a bit of shampoo in your palms. 
  4. Apply purple shampoo to your hair’s lengths, but make sure that you are avoiding the roots. Massage gently to work it into your scalp.
  5. Leave the purple shampoo on your hair and wash any residue from your hands. 
  6. Apply blue shampoo to your roots. Massage lightly and work it into your scalp if the orange undertones are strong and extra visible. However, you should try to not lather too much in order to keep the shampoo from spreading to other areas. 

Tip: If you bend your head over and have the hair flipped, hanging away from your head, you will have better control. 

The purple shampoo should stay on for: 

  • 2 to 3 minutes if your hair is naturally blonde 
  • Up to 15 minutes if your hair is brassy or color-treated
  • 30 minutes if your hair is gray, platinum, or silver

On the other hand, how long the blue shampoo should stay on for, depends on the hair’s condition. 

If you use it for 3 to 5 minutes, and you do not observe any reaction, then you can move up it to 10 to 15 minutes, and if needed, even up to 30 minutes. 

  1. After the designated wait time, wash the shampoo off with water. Note that there should be no soapy residues leftover. So, make sure you do this step thoroughly. 
  2. Follow up with a conditioner. A regular conditioner is fine. But you can also use a purple or blue conditioner. Condition as you normally would. 

Note: If your roots are yellow and your length’s ends are orange, do the above procedure in reverse.
