Hair color is a form of expression. We use it to enhance our natural color, cover up greys, or create a completely different look. Blue hair dye has become increasingly popular in recent years as it can create a vibrant new look or a fresh tint on your naturally darker color.

Read on to discover the best blue hair dyes for your hair.

What is Blue Hair Dye?

You can find blue hair color products in permanent and semi-permanent options. Depending on the look you are going for, each has its benefits.

Permanent Hair Dye

While it’s longer-lasting than semi-permanent colors, permanent hair dye is not entirely permanent. Permanent hair dye opens your hair’s cuticle so that it adds to your natural hair. But after a few washes, even permanent hair color can fade.

If you have stubborn greys or are looking for full, bright coverage, consider using permanent blue hair dye when coloring your hair.

Semi-Permanent Dye

Most permanent hair dye has ammonia, but semi-permanent is less harsh and generally uses fewer chemicals.

Unlike permanent hair dye that penetrates each strand, semi-permanent coats it with color providing a hair stain that fades and washes away.

Depending on your hair dye’s thickness or consistency, you may find it easier to apply with a brush or by hand. If you’re using your hands, you should wear gloves, even with semi-permanent color.

Once you have used all of your dye, massage it into your scalp from roots to ends to spread the dye to any parts of your hair you might have missed. You can also comb it through to ensure an even application.

Leave the dye in for as long as the directions recommend, and then rinse and style as directed.

Does Blue Hair Dye Work for All Hair Types?

If you are not naturally blond or fair-haired, you will need to pre-lighten your hair to achieve a vibrant, jewel-toned, or pastel blue color. Here is a quick reference on the level you will need to lift your hair to obtain your desired shade of blue:

  • Pastel blue is best for platinum blondes, or lift to a pale yellow;
  • Light blue shades are best for medium blondes, or lift to a golden yellow;
  • Dark blue shades are best for light brown hair, or lift to a light orange;
  • Blue-black hair is best for dark brown or any hair type and does not require pre-lightening.


Along with giving you all the mermaid vibes, dying your hair blue can benefit your overall health. Unlike bleaching or highlighting, most semi-permanent hair dyes are very conditioning, leaving your hair soft and restored. The shampoos and hair care products that prevent color fade are also conditioned and free of harsh chemicals and preservatives.

Whatever style you’re looking for, our list of best blue hair dyes has your hair type and color in mind, making salon-style hair achievable from home.


Could anyone be born with blue hair?

No, a human being can’t be born with blue hair.

Do blue hair dyes require bleaching?

Yes, if the color is lighter than your own. Also, if the color is similar to your own shade and you would like an exact match to the color you would like, it’s best to bleach first. 

How long can blue hair dye last?

Temporary blue dyes fade within two to six washes. Semi-permanent blue dyes can take up to 20 or 30 washes to rinse out fully.

A permanent dye fades but never completely washes out. You’ll have to re-color your hair or cut it.

Can I use blue hair dye on brown/dark hair?

Yes, but without bleach it might not show up if the blue color is similar in shade to your own. Or the resulting color might be skewed. If you’re using a much darker blue color, you should be fine.

What color cancels out blue hair dye?

On the color wheel, it’s orange, which cancels out the blue dye. So you can choose anything in the range of orange, including coppery tones.

Why does blue hair dye turn green?

Your hair can turn green easily due to mineral deposits in your tap water. Purple shampoo can keep the green at bay, or you might want to invest in a shower filter. 

Can blue hair dye damage hair?

Blue will damage your hair if you need to bleach it first, as bleach is always damaging. Otherwise, if you use a temporary or semi-permanent blue hair dye, neither should damage your hair.

However, if you change your mind and want to remove the blue color of a semi-permanent or permanent blue hair dye, the process of color removal can damage your locks.

Can I remove blue hair dye without bleach?

Yes, but it will be almost as damaging. Try a clarifying shampoo and then a bleach bath or a color remover for fashion colors.

At-home remedies include baking soda, strong vitamin C solutions, but these can corrode the hair and irritate the scalp.

How to get blue hair dye off my skin?

You can try makeup remover, baby oil, rubbing alcohol, dish soap, laundry detergent or petroleum jelly.

If the stains are still faint after trying one of these methods, repeat after a few days or let your skin turn over and remove the stain naturally within two weeks.
