The Hair Dye Issues

To permanently color the hair, potent ingredients in hair dyes remove the natural color and add new color to the hair shaft. To do so, the 2 most (un-)famous chemicals in hair dye products are hydrogen peroxide and ammonia. Hydrogen peroxide bleaches out the natural colour of the hair and releases oxygen to let chemical reactions take place. Ammonia is used to break down the cuticle around the hair shaft, letting the other chemicals to penetrate the hair (when the hair coloring happens). Other chemicals in hair dye products are para-phenylenediamine (PPD), parabens, ethanolamine, lead acetate, resorcinol, sodium lauryl sulfate (SLS) and have direct and indirect roles in the hair dye process.

Many of the chemicals found in hair dyes are harsh. Not only can they harm your hair, but they can be absorbed in small amounts through the skin or inhaled from fumes in the air too, leading to skin / scalp irritations, allergies, and respiratory problems. Some of them are even suspected carcinogens.

And it’s worth mentioning that too many hair dyes are still being tested on animals or contains animal products.

About Vegan Hair Dyes & Colors

Because they don’t contain these chemicals, 100% natural hair dyes may be seen as not effective or super short-lasting. While the actual results you’ll get are more subtle than their regular chemicals counterparts, natural hair dye products have been used all around the worlds for ages.

Most of them are based on Henna (Lawsonia Inermis) as the only natural component used for hair color, and others are derived from natural plants and minerals. They do cover all grey hairs, they enhance your natural color or can give shiny colors, while having hair conditioning properties. You can also add a tablespoon of coconut oil, or yogurt and an egg yolk to the mix which will help condition dry hair and skin.

But beware of compound Henna Dyes and read their labels carefully. They may use para-phenylenediamine (PPD), and trick you into believing the product is 100% natural by using botanical visuals and references.

Fortunately, we spent hours browsing the web in search for the perfect natural, cruelty-free and vegan hair dye that actually works. They are the safest way, not only for you and your hair, but for our lovely planet too ❤️!

“This is by far the best method for turning hair black WITHOUT any allergic reaction. (...) I found that Zenia products don’t contain any chemicals which is why I bought this to dye my hair black. I have tried several henna & herbal products in the market. Nothing came close to what this indigo powder did to turn my grey hair’s black. I purchased indigo powder along with henna powder to achieve black hair.”
