The warmest of the browns
Light Brown Doesn't Lighten.
It Warms.
Plant colour layers over your hair and never strips anything out, so no herbal colour can make hair lighter — ours included. Light Brown is seven organic herbs mixed with water, with less pigment than the browns above it: on darker hair the greys take it and turn honey, while the dark strands barely change. We tested it, measured it and photographed it for three days.
Read this before you choose it
If you have dark hair and want all of it to change, this is not the shade. Light Brown will warm it and add shine, but the change will be subtle enough that some people don't see it at all. That isn't a fault — it's what less pigment does.
Light Brown is the right shade if: your hair is already light to mid brown, or you have greys in darker hair and want them softened into honey rather than blocked out.

Not a list of things left out. A list of things the method never needed.
The one thing to know before you start: let it dry slowly. Wrap it in a towel or let it dry on its own. Dried fast — even with a cool fan — Light Brown stays orange instead of settling into brown, and it doesn't come back on its own. Low-porosity and resistant hair may need a second application.

The Drying Test
One Paste, Three Ways to Dry.
Only the Fast One Went Orange.
We put Light Brown on three white swatches — white so nothing underneath could hide the result, the closest stand-in for grey. Same paste, same 60 minutes, same rinse. The only thing we changed was how the hair dried. Then we photographed all three at 90 minutes, 24, 48 and 72 hours.
Paste: 1 part powder to 3.5 parts water by weight · 60 minutes on the hair · room at 76°F. The fourth swatch is the undyed control.
Top to bottom: fan (cool air), natural drying, towel drying, undyed control. Shot indoors by a window, so the daylight differs from photo to photo — compare the swatches inside one photo first.
The same three swatches, side by side
Each tile is cut from the same spot on the swatch in every photo. The numbers are read from those tiles: L* is lightness (lower is darker), a* is redness (higher is redder).
Dried fast, it stayed orange
The fan-dried swatch was the lightest of the three at every photo and about twice as red (a* 17.4 against about 9 at 72 hours). It darkened a little each day, but toward orange-copper — never into brown.
Dried slowly, it was brown at 90 minutes
Natural and towel drying were already a soft brown in the first photo, then warmed a little over three days. That warmth is Light Brown finishing as designed — it is the warmest brown we make.
Towel or natural: no difference
The two slow swatches stayed within one or two points of each other at every time point. Either works. The fan is the one that doesn't.
Let it dry slowly. No blow dryer — not even on cool.
The fan in this test blew room-temperature air. Heat wasn't needed to stop the colour — drying fast was enough. Wrap your hair in a towel after rinsing or let it dry on its own, and keep it off the dryer for the first 24 hours.
Why drying speed changes the colour
Light Brown is mostly henna and indigo, thinned with colourless henna (Cassia auriculata). Henna's colour, lawsone, is already in the leaf. Indigo's isn't — the leaf holds a precursor that water releases as indoxyl, and two indoxyl molecules join in air to form blue indigo. That reaction runs in water, on the hair.
Take the water away in five minutes and the indigo stops forming. What kept developing on the fan-dried swatch over the next three days was the warm side — most likely the henna, which is known to deepen for a day or two after rinsing. Light Brown carries the least indigo of our browns, so when the indigo stops early there is almost nothing left to turn henna's orange into brown.
We ran the same test with indigo on its own: the fan-dried swatch came out yellow-green, the towel-dried one blue-green. See the indigo test
Three things that help it finish
If it lands orange, faint or patchy
Bright orange instead of honey-brown is what the fan-dried swatch shows — it usually means the hair dried too fast, or the paste came off before 60 minutes. It doesn't reverse on its own, but it isn't damage: indigo alone for an hour is how most people bring it back toward brown, and it can go on the same day.
Barely any change on dark hair is not a failure — Light Brown can't lighten, and on dark strands its thin pigment mostly shows as warmth and shine. Faint on greys usually means low-porosity or resistant hair; a second application works better than leaving the first one on longer.
On our white swatches Light Brown showed no green stage, apart from small dark spots where paste pooled near the clip. Whether some hair types show one, we don't yet know.
Too light or too orange · Hard water · First-time customer support
How we measured: each tile is the median colour of that patch of swatch, with shine highlights left out, converted from the camera's sRGB to CIELAB. Paper in every photo was checked to be close to neutral. A phone photo is not a lab colorimeter: treat the numbers as a fair comparison between swatches, not as absolute values.
Measured in the Bowl
pH 5.60.
Right Beside Your Scalp.
We mixed Light Brown the way we tell you to and put a meter in it. Seven herbs and water read mildly acidic — nothing was added to push the number either way. Permanent box dye is made alkaline on purpose. This paste has no step that does that.
Where 5.60 sits
~5.5 Neutral
7 Permanent dye
9–11
Scalp and permanent-dye values are published figures (sources below). Only 5.60 is our own measurement.
A permanent dye mixes an alkali with peroxide so that the hair swells open and the colour can get inside. Light Brown doesn't need the hair open. Henna's lawsone bonds to the keratin and indigo settles into the cuticle surface. Neither needs the hair forced open, so there is no alkali in the bowl and nothing to neutralise afterwards.
5.60 is within about a tenth of the scalp's usual 5.5. Close, not identical — and we would rather show you the real number than round it.
What a pH number doesn't tell you
It isn't a promise that nobody reacts. Henna and indigo are plants, and a small number of people are sensitive to them — do a patch test before your first application, whatever the pH.
It isn't the whole difference either. Some demi-permanent dyes sit near pH 6–8 too. What separates them from this paste is the developer: Light Brown has no peroxide, no ammonia and no PPD, at any pH.
Mixing it the same way: start with 100 g of powder and 300 g of water, stir for two to three minutes, then add 50 g more water. That is the 1 : 3.5 we measured. How to apply

How It Works
One Takes Colour Out.
The Other Only Adds.
Both methods involve oxidation. The difference is what gets oxidized — your hair, or only the dye.
Conventional Light Brown Dye
Oxidizes
Your Hair
- Ammonia and peroxide pry the cuticle open, and the peroxide dissolves the melanin already inside
- Going lighter means lifting more. A light brown on dark hair needs a longer lift than a dark shade does — more of the reaction, not less
- Hair is dead tissue. It cannot rebuild what the reaction took — the damage stays until you cut it off
Light Brown
Oxidizes
Only the Dye
- Water carries the plant pigment onto the fibre. Henna's lawsone bonds to the keratin; indigo's pigment settles into the cuticle surface. Neither one needs the cuticle forced open
- The oxidation happens in the pigment, not in your melanin. Your own colour stays exactly where it was — which is why this shade shows most where there is no melanin left to compete with it
- Nothing was dissolved, so nothing needs repairing. That is what makes it repeatable on the same hair, over and over
This is exactly why Light Brown can't lighten. Going lighter means taking pigment out, and taking pigment out is the damage — there is no version of lifting that leaves the hair untouched. Radico skips that step altogether. It costs you the option of going lighter, and saves you everything that comes with it.
A hair sits on your head for two to six years before it sheds. Over that span, the shade that never lifted is the one still intact at the end of it.
What this doesn't mean
Plant colour is not a treatment. It won't repair damage that is already there, and on dark hair Light Brown may be barely visible — there is melanin underneath competing with a light, low-pigment shade, and melanin wins. That is the trade for not lifting. Hair can also feel dry for the first few days while the cuticle settles, and hard water and low porosity both make a faint shade fainter still.
The Sunlight Test
Warm Brown Indoors.
Honey in the Sun.
This is where the word light in the name actually comes from. Not from lifting your hair, but from how much gold the shade returns when the sun reaches it — more than any other brown in the range.
Both photos are Light Brown. They were taken on different occasions, so treat them as an illustration of the shift — not as a controlled side-by-side.
Compare this to Brown and the difference is the red. Brown turns copper in the sun; Light Brown turns gold.
The reason is on the ingredient list, if you put the two side by side. Where Brown has methi, Light Brown has colorless henna — cassia, a herb that contributes almost no colour at all. And it sits third, ahead of four of the herbs that do. A lighter plant shade isn't a stronger one. It's a thinner one, and that is why the sun finds so much of your own hair still showing through.

These photos are the upper end of what this shade does, not the average. Light Brown carries the least pigment of the browns, so on darker or low-porosity hair the change is subtler than what you see here — sometimes subtle enough not to read as a change at all. Depth also shifts with grey percentage, porosity, and processing time.
What's Actually Inside
Seven Herbs.
The Third One Doesn't Dye.
Ingredient lists run in order of quantity, and that order explains this shade. Indigo and henna lead, as they do in every shade in our Black & Brown range but one. Then comes colorless henna — a herb that barely tints at all, sitting ahead of four that do.
The two that lead — as in every Black & Brown shade but Mahogany
Third on the list — and it hardly tints at all
The rest — all four sit below it
Tap a herb to see its active compound and the evidence behind it
Here is what the order tells you, and it's printed on the pouch. Both this shade and Brown use seven herbs, so the difference is not how many. Compare the two lists and methi has come out, colorless henna has gone in — and it goes in third, ahead of manjistha, hibiscus, amla and bhringraj. On Brown, manjistha sits third and hibiscus fourth. Here they drop to sixth and seventh.
That is what makes Light Brown light. Not lifting, not bleaching, and nothing taken out of your hair — simply less coloring herb in every gram of powder, and the two that carry red pushed to the bottom. It also explains the trade-off: a thinner shade shows beautifully on light or grey hair, and can struggle to register on dark hair at all.
We don't publish the ratios. The proportions for each of the 24 shades are held by one person at our production facility in India. What we can hand you is the order they appear in.

What People Actually Buy
The most specific job in the range.
This is the smallest share of the four browns, and it drops off sharply from the three above it. That is what a narrow shade looks like in a sales figure — not a shade people default to, but one people arrive at once they know what it does.
From what customers tell us, that job is usually the same one: dark hair with greys coming through, and a preference for turning them into highlights rather than blocking them out. Which works for a reason that sounds like a contradiction until you look at the mechanism.
Grey hair holds no melanin. Plant pigment shows at full strength on those strands and barely registers on the pigmented ones around them. The shade cannot lighten your hair, but it lands lightest exactly where the colour is already gone.

Ready When You Are
A Narrow Shade,
Very Good at Its Job.
Light Brown isn't for everyone, and we would rather say so here than have you find out on day three. For the hair it suits, there isn't really a substitute in the range.
Choose Light Brown if
- You have greys in darker hair and want them softened into honey rather than blocked out
- Your own hair is already light to mid brown
- You want warmth and shine more than a change of shade
Choose something else if
- You have dark hair and want all of it to change — Brown or Dark Brown
- You want solid, even grey coverage rather than a highlight effect
- You want lighter than you are now — no plant colour can do that

Two things worth repeating: let it dry slowly. Wrap it in a towel or let it dry on its own — in our test, a swatch dried in five minutes with a cool fan stayed orange and never settled into brown.
And on resistant or low-porosity hair, expect a second application rather than a longer first one — this is a thin shade, and time doesn't substitute for pigment.
If it doesn't work on your hair, tell us
This is the shade we hear about most when a result comes out fainter than someone hoped, and we would rather sort that out than have you give up on plant colour altogether. First-time customers who don't get the result they expected can have the same shade sent again, a different shade sent free, or a full refund on the colour — no argument required. How the assurance works →
Before you use it: this shade contains indigo, which a small number of people react to. Do a patch test first, especially if you have sensitive skin or a history of reactions to plant dyes. Stop use if irritation occurs.
