Neutral henna is the powdered leaf of cassia obovata, a small desert plant from the senna family that is used as a hair pack because it conditions and adds shine without changing the colour of dark hair. Despite the name it is not henna at all: it gives no red stain, and on very light or grey hair it leaves only a soft golden tint.
What is neutral henna, in plain terms?
The name is a sales shortcut. Henna is the best known herbal hair powder, so any powder that is used the same way, mixed with water and left on the hair for an hour or two, tends to get called a kind of henna. The word neutral tells the buyer the part that matters, which is that it does not colour. It is bought by people who want the feel of a henna treatment without turning their hair red, and by people with light hair who do not want any orange at all.
Botanists list the plant as cassia obovata, although some newer books file it under a different name within the senna family. It grows wild, and is also farmed, in the dry belts of India, the Middle East and North Africa, where it survives on very little rain. After harvest the leaves are dried in the shade so they keep their colour, and then milled and sieved into a pale yellow green powder that smells faintly of fresh hay.
One plant, many names
Few herbs are sold under as many names, and that is where buyers get caught out. All of these usually mean the same leaf:
| Name you see | Where it is used |
|---|---|
| Neutral henna | Hair care shops, online stores, most of Europe and the US |
| Colourless or clear henna | Salons and natural hair brands |
| Cassia powder, cassia leaf powder | Traders and ingredient lists |
| Blonde henna | Usually cassia with a little real henna mixed in |
| Avali | Local name in parts of India |
Three other products are often confused with it, and each one causes a different kind of mistake. Real henna stains hair orange to red, so a customer who expected no colour will be unhappy. The senna leaf sold for laxative teas is a different plant in the same family, and it does not behave the same way on hair. And cassia cinnamon, the spice, shares the word cassia but has nothing to do with hair care.
What does it do to hair?
Mixed with warm water, the powder makes a smooth green paste that coats each strand while it sits on the head. Once it is rinsed out, the hair feels thicker and looks glossier, which is the effect people buy it for and the reason it sells as a conditioning treatment rather than as a dye.
On dark hair you will not see any colour. On blonde, white or grey hair it can leave a soft golden or straw tone, stronger on very light hair and with fresh powder. Many users like that warmth on grey. Brands should still say it clearly on the pack, because a customer expecting no change at all will be surprised.
One leaf, three trades
Hair care is the biggest market, but it is not the only one. Herbal and Ayurvedic medicine makers buy the dried leaf as a raw material, and cattle feed producers mix the leaf into feed for livestock. Because the same crop serves three very different buyers, it is sold in an unusual range of forms, from whole leaves pressed into 100 kg bales for a feed mill to 10 g sachets on a salon shelf.
How to tell real neutral henna from a substitute
A simple test catches most problems before they reach your customers. Mix a spoon of the powder with warm water, dab the paste on a piece of white cotton cloth or a light hair swatch, and leave it for two hours before you rinse it off.
- Faint yellow or no mark: what neutral henna should do.
- Orange or red stain: real henna has been mixed in, so it is not neutral.
- Dull brown or grey mark, or a sharp chemical smell: ask questions before you buy.
Smell and colour tell you the rest. Fresh powder smells green and grassy, a little like hay, while powder that smells of nothing, or looks dull brown rather than yellow green, is usually old or has been stored somewhere warm and damp. Neither will give the gloss your customers expect.

Frequently asked questions
Is neutral henna the same as henna?
No. Henna stains hair orange to red. Neutral henna is a different plant, cassia obovata, and gives no colour on dark hair. They are sold side by side because they are used the same way.
Is neutral henna the same as senna?
Not the senna sold for laxative teas. Neutral henna comes from cassia obovata, another plant in the same senna family. Check the plant name on the invoice, because the two are sometimes swapped.
Does neutral henna change hair colour?
Not on dark hair. On blonde, white or grey hair it can leave a soft golden tint, which is why some brands sell a version as blonde henna.
What is neutral henna called in India?
It is sold as neutral henna or cassia in hair shops, and as avali in parts of the country. Traders also use cassia powder and cassia leaf powder.
What is the minimum order for neutral henna powder?
25 kg. Whole leaves come in bales of 25 to 100 kg, powder in bags up to 50 kg, and private label packs start at 10 g. A free sample goes out first.
