What is Henna?

Pure Henna Hair Dye is Non Metallic Henna

Pure henna is one hundred percent plant !  It does NOT contain metallic salts. Sadly, many hairdressers are misinformed and are under the false impression that pure henna means henna powder mixed with metallic salts . Again, there is no metallic salt in pure henna and it is possible to dye over pure henna without having to cut it all out !

Beware :  metallic salts ARE added to products sold, misleadingly, as “henna”  and this creates a risk of your hair turning green when you dye it. Real henna does not do this. 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 powders 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. Then the crushed, powdered, leaves are finely sieved.

To create hair colour, 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.

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 henna safer than any chemical hair dye, but we can’t state conclusively that henna is 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 acids 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 trigger 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 golden rule of the henna 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.
