Finding an entirely chemical-free hair dye is virtually impossible, but luckily, some options are formulated with our health and wellbeing in mind.

As the hair industry continues to become more advanced and sophisticated, many of us have been seeking out haircare products that are friendlier towards the environment, our skin, and our general health. This is especially true of hair dyes, which are notorious for their chemically made formulas.

However, after doing some research, I realized that the term "clean hair dyes" is also not one to be trusted fully. That’s why, in this article, I will discuss the types of hair dyes and chemicals found inside them, as well as how these studies are usually conducted and whether they’re trustworthy.

Lastly, I will mention six non-toxic hair dyes that actually work and can be a great addition to your hair care routine.

Types of Hair Dyes

Hair dyes vary greatly in their chemical makeup. Currently, there are three main types of hair dyes in the market:

  • Temporary dyes: These dyes cover the surface of the hair but don’t penetrate into the hair shaft. They generally last for 1 to 2 washes.

  • Semi-permanent dyes: These dyes penetrate the hair shaft and typically last for 5 to 10 washes.

  • Permanent (oxidative) hair dyes: These dyes cause lasting chemical changes in the hair shaft. They’re the most popular hair dyes because the color changes last until the hair is replaced by new growth. These dyes are sometimes referred to as coal-tar dyes because of some of the ingredients in them.

Currently, cancer risk concerns are limited mainly to semi-permanent and permanent dyes. Also, it's worth mentioning that darker dyes have more of some potentially carcinogenic chemicals, which is why these products are of greater concern.

What’s Actually in Hair Dye?

Hair dyes usually contain colorless substances such as aromatic amines and phenols. In the presence of hydrogen peroxide, these substances go through chemical reactions to become dyes and change the color of the hair.

On a general note, darker hair dyes tend to use more of these coloring agents than lighter hair dyes, which is why the latter are considered safer by some users and professionals.

Chemicals in hair dyes might alter hormones like estrogen in the body, increasing cancer risks.

However, regardless of the color, there's a growing concern that some of the chemicals in hair dyes might alter the levels and actions of hormones like estrogen in the body, which can help certain cancers grow and spread, including some breast cancers.

Studying something like hair dyes can be even more complex because not all hair dyes are the same – they can contain any of thousands of different chemicals. On top of this, the ingredients in hair dyes have changed over the years. Early hair dyes contained chemicals, including some aromatic amines, which were found in the late 1970s to cause cancer in lab animals, so hair dye manufacturers changed some of the chemicals in their products.

Monthly hair dye use has been linked to bladder cancer in women.

With all that said, here's what we know about hair dyes being potential cancer triggers: According to research, most cancer risks are tied to dyes that color your hair permanently – not the ones that wash off after a few rinses. At high doses, some aromatic amines cause cancer in lab animals. Some studies show an increased risk of certain cancers in people who work with hair dyes or have been exposed to hair dyes continuously throughout their lives. But other research didn't find a link.

The strongest evidence so far is for bladder cancer: women in a case-control study in Los Angeles who reportedly used permanent hair dyes at least once a month experienced a 2.1-fold risk of bladder cancer relative to non-users.
