Non Metallic Henna
Pure henna does not contain any metallic salts which most hairdressers fear. Sadly, the misinformed opinion expressed here is all too common: https://thegildedpearltd.com/2016/08/08/why-you-should-never-use-henna-products-on-your-hair/ : “Henna body art (of the natural brown variety) is totally fine and can be a beautiful way to celebrate special occasions, as it is used in many different cultures around the world. Keep henna on your hands and feet, and away from that beautiful hair!” In fact, there is no metallic salt in pure henna and it is possible to dye over henna without having to cut it all out ! And it’s only the metallic salts added to products sold, misleadingly, as “henna” that risks your hair turning green when you dye it – not pure henna ! And it’s probably far safer and healthier to colour your hair with pure henna than with any chemical hair dye ! Our henna and indigo are recommended by dermatologists to patients with hair dye allergy.
What is henna?
It’s just a plant and it grows ! Some humans add metallic salts to their henna to create a fixed colour shade . We don’t. Because adding any harmful chemical product to your henna makes it into a chemical hair dye and renders it impure.
The henna plant grows up to six metres high in hot, arid, dry, conditions. It’s botanical name is lawsonia inermis. It’s a beautiful small shrub that produces small oval shaped green leaves and small white flowers. It survives in the harshest conditions. It gives pure and natural hair colour that is unique to you. The henna flowers are fragrant and may be white, pink, red or yellow; they are used in perfumes.
The natural hair dye from the henna plant comes only from its leaves. The leaves of the mature henna plant contain a red orange dye molecule called lawsone. The dye is extracted from the leaves by drying and crushing them, before sieving the crushed, powdered, leaves. The resulting yellow green henna powder is then mixed with water into a mud paste which is applied to hair as a natural hair dye. It will slightly deepen all dark hair colours and add mild auburn tones. On lighter hair colour tones it will colour auburn red. On grey hair it will colour fiery orange red. Indigo applied after henna will turn your henna hair colour brown through to black, depending how long the indigo is left in for.
Not all hennas are equal. Renaissance Henna plant hair dyes are made by crushing and then finely sieving the dried leaves of the henna plant multiple times to remove all traces of stalks and grit. The carefully harvested leaves and finely sieved powder ensures the strongest dye stain. Absolutely nothing is added to the finely powdered leaves and the pure, fresh, henna powder is packed immediately into a re-sealable poly bag before being factory sealed inside a strong foil pouch to protect it from light. And that’s it: – 100% plant hair dye, ammonia free, PPD free, additive free, chemical free hair dye ready to go. Simply add water, mix into paste and experience stunning natural herbal hair colour !
Pure henna hair dye can be used safely on all hair types including:

Pure henna hair dye can be used safely on most people including:
- pregnant mums
- PPD allergy patients
Some pregnant mothers like to get their bellies hennaed during pregnancy. A couple of words of caution here : if you’re a pregnant mother wanting to henna your hair, you’re probably sensitive to smells and plants, so we recommend you patch test first so you know what to expect. Unfortunately the powdered leaves which henna comes from don’t smell like flowers, they’re more musty, almost damp smelling. Secondly, you need to figure out if you’re comfortable using henna during pregnancy. We consider them safer than any chemical hair dye, but we can’t state conclusively that they are safe to use in pregnancy. The organisation Foresight seem to suggest that even vegetable hair dyes should be avoided in pregnancy.

The dye molecule in henna is called Lawsone. It’s a red orange pigment also known as hennotanic acid. Note that henna is acidic. This might sound disturbing, but so is skin, see:
Henna Plant Dye Release
When you apply henna to your scalp (the skin on your head), henna is boosting your skin’s natural defence systems.
Henna may vary in its dye content, depending on climate, soil, and moisture; so two batches – even from the same region – may never be quite the same. The finely crushed henna leaves- the henna powder – whilst acidic in nature, will chemically react with both water and acid ( such as lemon juice or cider vinegar). The addition of these liquids to henna powder will prompt the chemical reaction which causes release of the dye. Water produces faster dye release. Acid liquids triggers a slower dye release. Hot water works faster than cool water. A long slow dye release time, with either water or acid juice, or a mixture of both, works well to get henna into overtime dye release mode. But straight hot water over pure henna is the most effective method if you’re in a hurry and want the fastest dye release. Henna is versatile. And therefore all the approaches to henna and theories about henna should be versatile too. There are no hard and fast fixed rules. The rule of the game is : when you’ve discovered the treasure, make up your own code. Go with what works for you. And keep an open mind, experiment, and enjoy the journey. You really can’t go wrong. It’s been around for centuries. It’s already stood the test of time. And it won’t be bound by rules. It’s for everyone.
