Hair dye has been around since ancient times.

Hair dye has been around since ancient times. Ancient Egyptians used henna to dye their hair, while the Ancient Greeks and Romans used beets and walnut shells to dye their hair. In China, the use of copper sulfate for coloring was common, while in India during the 11th century indigo was used for coloring.

Egyptian women used henna on their hair.

If your hair is already dark, henna is a great option for you. It’s a natural dye made from the leaves of the Lawsonia inermis plant, and has been used for centuries. In fact, it may be one of the oldest dyes used on human hair. When mixed with plant ingredients like lemon juice or tea leaves, it can create a range of colors including reds, golds and even black—the same colors that would later be achieved using chemical dyes!

In India especially (where it’s known as mehndi), henna is often applied to decorate hands and feet before festivals or weddings. Some families will use this technique as an alternative to dying their children’s hair unnatural colors when they turn one year old (and then again at three years old). Because henna is so safe for both adults and kids alike—it contains no harmful chemicals—it may also be used during pregnancy without risk of damaging your unborn child’s health!

The first synthetic hair dye was created in 1907.

The earliest recorded use of PPD, or para-phenylenediamine, was 1907. And it was created by an American chemist named William H. Perkin. He made it from coal tar and used it to color cloth for dresses and suits—and also dyed hair.

Before you go getting excited and envisioning yourself as a woman from the early 1900s (or even a man!), please don’t let me mislead you: today’s hair dyes are safer than they were back then.

This shade of blue is known as “Mermaid Blue”.

Mermaid Blue is a very light blue, almost white color. It’s perfect for those with light hair who want a subtle change in color.

If you’ve ever seen someone with this shade of hair, they’ll have told you it’s not something they can just rock up on the spot. They need to get their roots done so it looks like there’s more depth and dimension in their hair than there actually is!

Some people choose to use blue hair dye on their skin to create tattoos.

You might be surprised to learn that some people use blue hair dye on their skin as a temporary tattoo. This can be great for kids who want to get tattoos, but aren’t old enough yet. It’s also easy to remove with soap and water or rubbing alcohol if you change your mind about it.

The permanent option tends to work best with gray, platinum, light blond or white hair.

If you’re thinking of dyeing your hair blue, the permanent option tends to work best with gray, platinum, light blond or white hair. If you have dark hair and want it to stay blue for a long time (say until your next job interview), then the non-permanent option is for you. The permanent option is more expensive than the non-permanent one because it’s more likely that your color will fade faster and require another application of dye within just a few days. The non-permanent version can be used on any type of hair as long as there’s enough length remaining for applying it evenly across your head (which means no clumps).

If you have dark hair and want it to be blue, you can use the non-permanent option, but you may find it takes several applications before your hair turns blue.

• If you have white or light-colored hair and want to dye it blue, one of the best options is to use a blue dye designed for white hair. These dyes will give a more natural tone than if you used any other type of shade without understanding how they work.
• If you have dark hair and want it to be blue, you can use the non-permanent option, but you may find it takes several applications before your hair turns blue. In general, this technique will take longer than using permanent dyes on lighter shades because darker colors are harder for dye molecules to penetrate into strands of hair. Also keep in mind that some permanent dyes include chemicals which can damage your scalp over time—a risk worth avoiding if possible!

Blue hair can be fun, but remember to consider the effects before making a decision

Finally, you should consider the effects. Blue hair is all fun and games until it fades away and becomes green. Then you’re stuck with this weird color in your hair that doesn’t look good on anyone and can only be fixed by bleaching or dying out completely.

If I had to do it over again, I would have gone for a more natural shade of blue that’s less likely to fade or turn green. It will be interesting to see what happens as time goes on though!
