Non Toxic Hair Dye - Does it Exist?

non toxic hair dye

We have such a love - hate relationship with hair dye. We love how it makes us look but hate the damage it does to our hair and the potential health risks from exposure to all those chemicals.

And there sure are a lot of chemicals in hair dye. In fact, according to the National Cancer Institute more than 5,000 different chemicals are used in hair dyes. Many of these chemicals are allergens, skin toxins, endocrine disruptors, toxic to cells and organs and cause cancer.

Some of the worst offenders in hair dye include:

  • Parabens are used as preservatives and fragrance ingredients. They are endocrine disrupters and some cause breast cancer. Propylparaben is the most toxic.

  • Resorcinol is an endocrine system disrupter, organ system toxicant, immune system toxicant, allergen and linked to hypothyroidism.

  • P-Phenylenediamine (PPD) is among the most commonly used hair dye compounds and it is classified as a carcinogen. It is also a skin, eye and lung irritant and allergen. 
  • Toluene-2,5-diamine sulfate is an allergen, skin and immune system toxicant and there is some evidence that it may cause inflammation and cancer. 

  • Fragrance is added to cover chemical smells and any of the 100’s of different mystery chemicals that make up a fragrance may be in hair dye. Unknown chemicals means unknown health effects. Plus, where there’s fragrance there are often endocrine disrupting phthalates, which are used as a scent carrier.

The Risks To Your Health

There’s no question that dying your hair is risky to your health. Numerous studies have detected the presence of components of hair dye in the urine of people within hours of dying their hair.

This means the toxic chemicals in hair dye are absorbed through your skin. Once that happens they travel through your blood to various organs in your body and damage your health.

And, as you age your skin and your blood-brain barrier become less effective barriers from toxins. That means the chemicals in hair dye and other products can be absorbed through your skin into your blood stream and from your blood stream into your brain more easily.

Hairdressers, who are regularly exposed to the chemicals in hair dyes, are often studied to identify the health effects of hair dye exposure. They have been found to have a higher risk of non-Hodgkin lymphoma, bladder cancer and other types of cancers.

Personal use of hair dyes is also associated with breast cancer. If you regularly dye your hair one study reported the odds of breast cancer increased by 23% and women born before 1950 an increase of 28% was found.

Some studies have found a small increase in the risk of digestive diseases among the women using hair dye and an increased risk of Parkinson’s disease among users of personal hair dye.

Population studies have also found that if you use permanent hair dye at least once a month you have a 2.1 times higher risk of bladder cancer in comparison with women who don’t dye their hair. However, other studies have concluded that dying your hair did not increase the risk of bladder cancer.

Non Toxic Hair Dye?

Many of you want to know if there is any such thing as a non toxic hair dye? Does such a wonderful, magical product exist? My answer is yes – and no.

Yes, if you are willing to lower your expectations about hair dyes. By that I mean that there are non toxic henna and vegetable based hair dyes that are semi-permanent. They may not give the same consistent results as more toxic dyes and they have to be reapplied more often. They are not great at covering gray and fade after 6-12 shampoos. However, the Environmental Working Group rates the toxicity of these types of dyes as 0 on a scale of 0-10. Brand names for these dyes include: Light Mountain Hair Color, Morrocco Method International Henna and Sante 100% Herbal Hair Color.

So, if you just like changing up your hair color these are your least toxic options.

But, if you’ve gone gray and want to restore your natural hair color there is a new nontoxic solution that I’ve heard great things about. It’s called Hairprint and it doesn’t contain endocrine disruptors, carcinogens, fire retardants, GMOs, heavy metals, pesticides and ingredients that are known behavioral, developmental, reproductive and neurotoxins.

Currently, Hairprint Color Restorer is only available for naturally black, brown, and light brown hair only. They do not have a formula for naturally blonde or red hair.


According to its website:

“Hairprint functions in a way that is the opposite of how hair dyes work. Rather than stripping hair of its color and inserting coal tar dyes, which all permanent hair-coloring products do, Dr. Warner's process mimics how hair gets its true color in the first place. The color responsible for all brown and black hair is eumelanin, which is a variation of the melanin pigment that is responsible for the color of your skin and eyes. The reason Hairprint looks so natural on your hair is because it is natural.”


Less Toxic Hair Color Options

If non toxic options don’t work for you there are some less toxic hair dye options. If you have your hair dyed at a salon consider switching to one that uses safer products. Do a Google search for salons that focus on organic, chemical free or less toxic hair care products.

Or have a conversation with your stylist about using safer hair dyes. You could also bring your own products for your hair dresser to use.

For example, the following options range from 2-5 on the toxicity scale. I have never tried any of these options because I have never dyed my hair. When the first grays started to appear I decided to embrace them. So these suggestions are based only on my toxicity research and not on how well the products work.

Naturtint has no ammonia, resorcinol, or parabens. The most toxic chemical it contains is cocamide DEA, a chemically-modified form of coconut oil used as a foaming agent. This chemical is considered to be a possible human carcinogen by the California EPA. The hair dye gets great reviews and does a good job covering grays.

Herbatint Permanent Herbal Haircolour Gel contains ethanolamine, an immune and respiratory toxicant that is used as a pH adjuster and Resorcinol. Endocrine disruption is a high concern with this product.

EcoColors Haircolor provides a list of its non toxic ingredients on its website. That list is followed by a list of much more toxic ingredients that MAY be in the product. That concerns me. For example, 1,3 benzenediol, a synonym for resorcinol, which the company claims it does not use, is on the list. Also, 1 naphthol, a carcinogen, allergen, lung and skin and organ system toxicant. If all the “maybe” chemicals were in the dye, this product would rank a 6 on the EWG toxicity scale.

Hair Dyes with Mid-range Toxicity

Some options in the 5-6 toxicity scale range that pose a moderate hazard include Loreal Inoa Ammonia Free Permanent Hair Color and Garnier Olia Oil Permanent Hair Color. Both of these options contain resorcinol and fragrance. The chemicals in these hair dyes pose a high risk for endocrine disruption. Another option is Clairol Natural Instincts, which contains fragrance, but no resorcinol. All three of these dyes are thought to pose a low cancer risk.

Very Toxic Hair Dyes

Hair dyes in this category contain multiple sources of carcinogens, allergens, endocrine disrupters and organ system toxicants. This is known as multiple, additive exposure sources. For example, Revlon Colorsilk contains 18 chemicals that pose a moderate to high health hazard.

Because of their use of parabens, especially propylparaben, some hair dyes earn a 10 out of 10 on the toxicity scale. These include Crème of Nature Exotic, John Freida Precision Foam Color and Loreal Superior Preference Fade Defying Hair Color.

If you’re serious about reducing your exposure to the chemical toxins in hair dyes I suggest you try some of the nontoxic alternatives first. If they don’t work for you move to the low toxicity options. Another tip is to go lighter in color. In general, the darker the color the more toxins are in the dye. Of course you could just embrace your natural hair color and learn to love those grays.
