Q: Will blue shampoo reduce yellow tones in my naturally silver hair?

No, for that you will need to try purple shampoo or (my favorite solution) QuickSilverHair Clay .

Question 1

What will happen to my gray roots if I use blue shampoo?

Accepted Answer

Blue shampoo will not have much effect on your gray roots except to perhaps make them look a little brighter against your dyed ends. If you overuse blue shampoo, however, your gray roots might take on a bluish tint.

Question 2

What effect does blue shampoo have on brassy red tones?

Accepted Answer

Blue shampoo reduces the appearance of brassy orange tones. It won't help neutralize brassy red tones; for that, you'll need a green shampoo as green is the opposite of red on the color wheel.

Question 3

Will blue shampoo reduce yellow tones in my naturally silver hair?

Accepted Answer

No, for that you will need to try purple shampoo or (my favorite solution) QuickSilverHair Clay.

Question 4

Does blue shampoo work after one use?

Accepted Answer

You should see results after one application unless your brunette dye has faded to SUCH a brassy orange that no amount of blue shampoo will help.

Question 5

How long does it take for blue shampoo to work?

Accepted Answer

Anywhere between 3-10 minutes, although 5 minutes on dry hair works well for most people.

Question 6

Does blue shampoo make brown hair lighter?

Accepted Answer

No, it won't lighten your hair color. Its purpose is to neutralize orange, brassy tones in dyed brunette hair.

Question 7

Can I dye over brassy hair?

Accepted Answer

Yes! If your brunette dye is fading and hopelessly orange, dyeing it will cover the orange tones. Just remember, once the dye starts fading again, the brassy tones will come back.

Question 8

How often should I use blue shampoo?

Accepted Answer

Blue shampoo is very drying, so limit your use to once per week, and always follow up with a deep conditioner.

Question 9

If I'm going gray from brunette hair, do I have to use blue shampoo?

Accepted Answer

Blue shampoo is not mandatory; you only need to use it if the brassy tones in your fading brunette-dyed hair bother you. If the brassiness does NOT bother you, skip the blue shampoo and just use your regular shampoo while you're growing out your gray hair.

Question 10

I'm fully transitioned to gray hair - how will blue shampoo help me?

Accepted Answer

If your hair is fully gray, there's no need for blue shampoo. It won't hurt your hair but it won't help it much either (it might make it a little brighter, but for better brightening and reduction of yellow tones in your gray hair, try purple shampoo or QuickSilverHair Clay).

Question 11

Will blue shampoo work on natural (undyed) brown hair?

Accepted Answer

Yes! Blue shampoo can help reduce brassy tones in natural brown hair caused by sun exposure, chlorine, etc.

Question 12

What blue shampoo do you recommend?

Accepted Answer

My favorite blue shampoo was Joico Color Balance Blue Shampoo. It worked beautifully and did not dry out my hair as long as I followed it up with a deep conditioner. Other recommended blue shampoos can be found here.
