Katam Powder and Henna: The Sunnah Beard Dye, Explained
Katam powder is the dried, ground leaf of a plant mentioned in hadith alongside henna as a dye for grey hair. Mixed with henna and left on the beard for 1 to 2 hours or more, it shifts henna’s copper toward a dark brown. It doesn’t give jet black, and a lot of what’s sold as katam in shops is actually indigo. Here is what katam is, how to tell real from relabelled, and how it’s used.
Quick facts
- What it is: a leaf powder, most often identified as Buxus dioica, a shrub of Yemen and the Arabian Peninsula.
- Colour with henna: darker brown than henna alone; not black.
- Tradition: Tibb-e-Nabvi and Sunnah practice for colouring grey hair.
- Common fake: indigo sold as “katam”.
- Safety: patch test 48 hours before; never a product that dyes black in minutes.

What is katam powder in English?
There isn’t a neat everyday English name. Katam (also written katm or ketem) is an Arabic plant name, and most sources link it to Buxus dioica, a small shrub in the box family that grows wild in Yemen. Some older books point to other plants. That uncertainty is part of the story, and it’s why buying it is tricky.
In Urdu and Hindi shops the word “katam” is the same, and in English the honest translation is simply “katam, a plant dye used with henna”.
Did you know? If katam is Buxus dioica, it’s a cousin of boxwood, the hedge plant whose hard, fine-grained wood has been carved into combs and chess pieces for centuries.
Don’t confuse it with katha (kattha, the brown catechu paste from the khair tree used in paan). Different plant, different use, and katha isn’t a hair dye at all.
Why do Muslims use katam and henna on the beard?
Hadith collections record that the Companion Abu Bakr coloured his grey hair with henna and katam, and a narration in Tirmidhi and Abu Dawud names henna and katam as among the best things to change grey hair. Tibb-e-Nabvi (Prophetic medicine) writers carried this into their books, and in many Pakistani and Indian Muslim families, colouring the beard with henna, or henna and katam, is a valued Sunnah.
On pure black dye, scholars differ. Several narrations are read as discouraging jet black, and many scholars hold it disliked or not allowed, while others permit it in some situations. We don’t rule on this. If it matters to you, and it does to many readers, ask a scholar you trust.
The chemistry is simpler. Henna and katam give brown. Not black.
What people say, what tradition says, and our honest take
What people say: katam makes the beard black, it’s “stronger than indigo”, it grows a thicker beard, and every green powder labelled katam is the real Yemeni plant.
What tradition says: henna with katam is the recommended colour for grey hair, giving a dark shade between red and black.
Our honest take Depends: genuine katam is a reasonable plant dye that deepens henna. Its colour effect is real but milder than indigo, and nothing suggests it grows hair. The biggest problem is fake or relabelled powder, and that you can partly guard against.
Katam powder vs indigo powder: how to tell
A lot of “katam” in markets, and online, is indigo. Indigo gives a stronger, bluer dark, which buyers like, so sellers relabel. It isn’t dangerous if it’s pure indigo, but it isn’t what you paid for, and it behaves differently.
| Check | Real katam | Indigo |
|---|---|---|
| Dry powder | Olive or khaki green | Dark green-blue to navy |
| Mixed with water | Stays green-brown | Turns blue-green; coppery film |
| On white hair alone | Faint greenish to brown tint | Blue or green |
| Hands after mixing | Little staining | Blue-grey stain |
None of these is proof, and a mixed powder will confuse every test. Buy from a seller who names the plant and the origin, and be wary of anything that turns black in the bowl or promises black in minutes, which points to PPD (the chemical in permanent hair dye) rather than any plant.
How to use katam powder with henna on a beard
Most families mix the two in one bowl. Proportions vary from house to house, from beard to beard and even from packet to packet, because the strength of a dried leaf powder depends on where it grew, how it was dried and how long it sat on a shop shelf, so treat the amounts below as a starting point and adjust after the first try.
- Make your henna paste first: about 20 g of pure henna with roughly 40 to 60 ml warm water, covered and rested 4 to 8 hours until the dye releases.
- Just before applying, mix about 10 to 20 g of katam with a little warm water and stir it into the henna. More katam gives a darker brown.
- Wash and dry the beard. Put petroleum jelly along the skin edges and lip line.
- Wear gloves and work the paste into every hair, against the grain, then smooth it down.
- Wrap loosely and leave 1 to 2 hours. Coarse beards often get 3.
- Rinse with water only. Avoid shampoo for 48 hours while the shade deepens.
Some people prefer two steps, henna first and katam second, the way indigo is used. It gives a little more depth. For the classic henna method on its own, see our mehndi for beard guide, and if you’re after the darkest result, compare with henna and indigo.
Henna alone is copper. Henna with katam is brown. Neither is jet black.
Myth: katam makes your beard grow thicker
There’s no good reason to think so. Katam, like henna, coats the outside of hairs, so a coloured beard can look a bit fuller simply because the white hairs no longer disappear against the skin, and that visual effect is probably where the claim began. Beard thickness is set mostly by genes and hormones.
Katam powder side effects and storage
Real katam is not well studied on skin. Tradition isn’t proof. It has a long record of use on beards across Arabia and South Asia, which is reassuring, but a long record of use is not the same thing as known safety for your particular skin, and a powder whose identity even botanists argue about deserves more caution, so patch testing matters more here, not less.
- Possible irritation or allergy, as with any plant on the face.
- Some skin staining, usually lighter than indigo.
- The bigger danger is adulteration with PPD or metallic salts.
Store it like henna: airtight, dark, cool and dry, and use within a year. Don’t eat it or drink it. It’s a dye.
Patch test both katam and henna 48 hours before: a dab behind the ear for the full time, then rinse. Any itching, redness or bumps means don’t go ahead. Keep the paste off your lips and out of your eyes, and skip it on broken skin or a beard rash. Henna can harm people with G6PD deficiency, so ask your doctor first if you have it, and keep powders away from children. Face or lip swelling, blistering, or breathing trouble after any beard dye needs medical help that day.
