What is Blue Hair Dye?

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.

 

How to Use Blue Hair Color Products

How to Use Blue Hair Color Products

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 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 any pre-lightening.

 

Benefits

Along with giving you all the mermaid vibes, dying your hair blue can benefit its 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 conditioning and generally free of harsh chemicals and preservatives.
