The short answer
Henna for hair is a natural dye made from the dried, powdered leaves of the henna plant (Lawsonia inermis). Mixed to a paste with water, and often lemon juice or tea, and applied to the hair, it stains it a reddish, coppery to auburn tone and also conditions, strengthens and adds shine. The colour is long-lasting and builds with repeat use, it does not lighten hair, and the final shade depends on your natural colour. Use only pure, body-art-quality henna, do a strand and skin patch test first, and find the powder at Afro hair and beauty shops near you on African Stores.

Henna has been part of beauty and celebration across North Africa, the Middle East and South Asia for centuries, painted on skin for weddings and festivals and worked into hair as a natural colour and treatment. For many families in Britain it carries that memory, the smell of the paste, the patience of letting it sit, the deep red shine it leaves behind. It is one of the oldest beauty traditions still in everyday use, passed from mothers and grandmothers as a trusted, plant-based way to care for hair.
There is something grounding about reaching for a natural powder rather than a boxed chemical dye, especially for those raised to see henna as ordinary good grooming. It sits comfortably in the wider culture of natural hair and beauty care in African and Caribbean communities here, where oils, butters and plant treatments are valued for doing more than one job at once. To mix a bowl of henna at home is to keep a long tradition going, and to hand the habit on is to share it.
What Henna for Hair Actually Is
Henna is a natural dye made from the leaves of the henna plant, Lawsonia inermis, a shrub that grows in hot, dry regions. The leaves are dried and ground to a fine green powder, which is what you buy for hair. On its own the powder does nothing; it has to be mixed to a paste with a mildly acidic liquid, usually water with lemon juice, or brewed tea or coffee, and left to stand so the dye is released before it will colour anything. The active colour molecule in the leaf binds to the keratin in hair, which is how the stain takes hold.
Pure henna gives one colour family, a reddish tone that runs from coppery orange to deep auburn depending on your hair and how long the paste is left on. It is not a chemical dye and it does not lighten hair, so it cannot make hair blonde or lift dark hair to a lighter shade. This is worth knowing before you start, because henna works with your natural colour rather than replacing it. It has a long tradition across North Africa, the Middle East and South Asia, used both as a hair colour and as a skin decoration for weddings and festivals.
What Henna Does to Hair
The obvious effect is colour. Henna stains hair a rich, warm red that is translucent, so it layers over your existing shade rather than covering it flatly. On dark hair it reads as a subtle red or auburn glow in the light; on lighter or grey hair it shows up far more strongly as coppery orange. The colour is long-lasting and does not simply wash out, and because it builds with repeat use, the tone deepens and grows richer the more often you apply it.
Beyond colour, henna is valued as a conditioning treatment. It coats and binds to the hair shaft, which can leave hair feeling thicker, smoother and stronger, with more shine and better definition. Many people use it as much for that strengthening, glossing effect as for the colour itself, and some find it helps lie down frizz and gives coils a cleaner, more defined shape. Because it works by coating the strand, the effect is cumulative: hair often feels more robust the longer henna is part of a routine, which is one reason it has stayed popular for so long.
This kind of plant-based, do-more-than-one-job care fits naturally alongside other treatments people use on textured hair, and if you are learning what suits your curls it sits comfortably next to routines for 4C hair. It is worth remembering that henna is a commitment, though. The colour does not lift out, so it is not easily reversed, and chemically lightening hair over a henna layer can be unpredictable. As with any beauty product, do a patch test before your first use; this article is general beauty information, not medical advice.
How to Use Henna on Hair
Using henna is simple but slow, and the waiting is part of it. You mix the powder with your chosen liquid to a yoghurt-like paste, cover it and leave it to stand, often for several hours or overnight, so the dye releases. The paste is then applied to clean hair in sections, worked through from roots to ends, and left on under a cap for anywhere from one to several hours; the longer it sits, the deeper the stain. It is then rinsed out thoroughly, and the true colour usually settles over the following day or two.
Two tests come first, every time. Do a strand test on a small hidden section to see the colour you will actually get, since results depend on your natural shade, and do a skin patch test a day or two ahead to check you do not react. Most importantly, use only pure, body-art-quality or natural henna. Avoid so-called "black henna" and compound hennas, which can contain added PPD (para-phenylenediamine); this chemical is not true henna and can cause severe skin reactions. Reading the label matters: real henna lists only the plant, sometimes with other natural powders, and never a synthetic dye.
Where to Buy Henna in the UK
Henna is widely sold in Britain, but quality varies a great deal, so it is worth buying from shops that know it. Afro and Asian hair and beauty shops stock pure henna powder, often in several grades, and the staff can point you to a body-art-quality product rather than a compound one. They will also usually carry the small extras that make application easier, from mixing bowls and brushes to gloves and caps. Look for a powder that lists only Lawsonia inermis, or henna with other natural plant powders, and steer clear of anything advertising a "black" or instant result. Buying in person also lets you ask about mixing and colour, which helps if it is your first time. You can find an Afro hair and beauty shop near you on African Stores to pick up pure henna and the bits you need to apply it.

Many people find henna good for hair because, as well as colouring it, it coats and binds to the hair shaft, which can leave it feeling thicker, stronger and shinier with better definition. It is valued as a natural, plant-based treatment. As with any product, do a patch test first, and this is general beauty information, not medical advice.
Is henna safe to use?
Pure, body-art-quality or natural henna is generally well tolerated, but you should always do a skin patch test and a strand test before your first use. The real risk comes from "black henna" or compound hennas that contain added PPD (para-phenylenediamine), which can cause severe skin reactions. Use only henna that lists the plant and natural powders, never a synthetic dye.
