Frequently Asked Questions

1. What is the best blue dye for dark hair?

The best blue dye for dark hair is a light water-soluble shade, such as azure or thistle. 

Before dying, take precautions against the damage that could be done by heavy chemical dyes to your hair by using a dyeing technique called “pouring,” where instead of applying a heavy coating of color to your hair with a comb, you playfully pour it on from about six inches away. 

This will result in an even distribution of color right the way through to the roots and leaves any stubborn patches untouched.

2. Does blue or purple last longer?

The blue color tone of hair dye is created by the chemical PPD, which has a long half-life. The purple shade is created with hydrogen peroxide and no other chemicals like ammonia or resorcin. It will last about 3-4 weeks in warm water and 10-12 weeks in cold water.

3. Does blue dye show up on brown hair?

Yes. Blue dye can show up on brown hair, but it will take some time to do so because the portion that is bleached often reacts first. The new blue hair will then blend in with the brown portions over time as they fade to blonde/argyle or until you decide to maintain your blue look and re-dye your entire head of brown hair a different color.

4. What is the hardest color to remove from hair?

The hardest color to remove hair dye is purple. Red dyes are not as difficult, and can be removed with henna. Blue (indigo) dye requires a semi-permanent shade of henna and takes the longest to wash out. 

Black hair has the longest lifespan (about six weeks). Pink or blonde color will fade more quickly than brown because they need lighter shades of henna to counteract it. 

In general, dark colors last longer than light ones because they require stronger chemicals in order for them to remain vibrant on your locks while fading in intensity over time from exposure to natural sunlight and chlorine from the pool water.

5. Is it hard to get blue hair dye out?

It’s not hard to get blue hair dye out at all, especially with the right use of shampoo.

The best type of shampoo for blue hair types is the purple boxed one with a green lid. This will pull any residual pigment color from your hair, both on the scalp itself and in strands that may have strayed down onto your face or neck area while you were applying it.

6. Is blue hair easy to maintain?

The answer to this question depends on a couple of factors. You can look at how often you wash your hair, how damaged your locks are and what products you’re using. 

For example, if you’ve got excessively long locks that have been mistreated for years with bleach and curlers, then it’s going to take a serious investment in time and money to get them back up again.

Whereas those who have dyed their hair blue with clear old fades will likely only need some normal shampoo to maintain it as well as replacing the color about once a month. The same applies for those who simply paint streaks here or there.
