Rice Water for Hair and Face: Exact Ratio, Ferment Time, Limits
One part rice to two parts water. Soak 30 minutes, strain, then either use it fresh or leave the strained water covered at room temperature for 12 to 24 hours until it smells faintly sour. Dilute the fermented version half and half before it touches hair or skin. That’s the rice water formula, and this article gives the exact amounts, the timings for Pakistani and Indian weather, and the honest bit most videos skip: who it makes worse.
Quick facts
- Ratio: 100 g (half a cup) rice to 200 ml water
- Plain version: soak 30 minutes, strain, use the same day
- Fermented version: 12 to 24 hours covered on the counter, then dilute 1:1
- Keeps: 3 days in the fridge for either version
- On hair: after shampoo, 5 to 10 minutes, rinse out, once a week
- On face: as a toner on cotton wool, once a day at most, patch test first
- Skip it: fine or low-porosity hair that goes stiff, eczema, any scalp condition

What is the exact rice water ratio for hair and face?
The 1:2 ratio matters because it decides how strong the water is. Too much water and you get a cloudy nothing. Too little and the starch dries on hair like a film. Half a cup of raw rice, which weighs about 100 g, to 200 ml (a standard chai cup) of clean water lands in the right place for both hair and face.
Any plain rice works: basmati, sella, tota, or the cheap broken rice sold for kheer. Skip flavoured or parboiled-and-seasoned mixes. Rinse the rice once under the tap first, for about 10 seconds, to wash off dust and any polish; that first rinse water goes down the sink. The second soak is the one you keep.
How to make plain rice water (30 minutes)
- Rinse 100 g rice under running water for 10 seconds and drain.
- Put the rice in a clean bowl with 200 ml room-temperature water.
- Swirl and squeeze the grains with your fingers for a minute until the water turns milky.
- Leave it 30 minutes.
- Strain through a chai strainer into a clean bottle. Cook the rice as usual; nothing is wasted.
- Use the same day, or refrigerate for up to 3 days.
Plain rice water is the gentle option and the right one for a first try. It has the starch, a little of the rice’s protein, and the sugar-alcohol called inositol that gets the credit for shine, without the sourness or the smell.
How to ferment rice water (12 to 24 hours)
Fermenting means letting the natural yeasts and bacteria on the rice work on the starch. The water turns slightly sour, the pH drops, and many people find their hair feels smoother and lies flatter after a sour rinse, in the same way a dahi mask does. It’s a mild effect, not a transformation.
- Make the plain version above and pour the strained water into a clean glass jar.
- Cover loosely with a lid or a saucer. Don’t seal it tight, because the gas needs to escape.
- Leave it on the counter out of the sun. In summer heat (30 °C and above), check at 12 hours. In winter, it may need the full 24.
- It’s ready when it smells faintly sour, like the first day of dahi, and a thin layer of white sediment sits at the bottom. Any fizzing, pink tint, fuzzy growth or a smell that turns your stomach means throw it away.
- Stop the ferment by moving the jar to the fridge. Use within 3 days.
- Before use, dilute 1:1 with plain water, so 100 ml of fermented rice water becomes 200 ml of rinse.
How to use rice water on hair, and how often
Shampoo first, because rice water does nothing through a layer of oil and dust. Squeeze out the excess water, then pour the rice water slowly over the scalp and lengths, working it through with your fingers. Leave it 5 to 10 minutes. Rinse thoroughly with plain water, then use conditioner on the lengths if your hair is dry or long. Once a week is plenty. Twice a week is the ceiling, and only if your hair clearly likes it.
If you already make the reetha and shikakai wash, rice water slots in as the last rinse after it. The recipe, quantities and the eye-stinging warning for that shampoo are in our reetha shikakai and rice water guide, so use the two together rather than reading the same steps twice.
How to use rice water on the face
Plain rice water, not fermented, is the better face choice for most skins; the fermented version stings some people. Wet a cotton pad, wipe over a clean face, and let it dry on the skin. Follow with your usual moisturiser. Once a day, usually at night, is the most anyone needs. If your skin is oily, it can feel pleasantly tight. If your skin is dry, it can feel too tight, and that’s your answer.
What it can honestly do: leave skin feeling smooth and a little matte for a few hours. What it can’t do: fade dark spots, shrink pores, whiten anything, or stand in for sunscreen.
Protein overload and the people who should skip it
Here’s the part the viral videos leave out. Rice water leaves a coating of starch and small proteins on the hair shaft. On thick, coarse, high-porosity hair, that coating fills gaps and the hair feels stronger and shinier. On fine, straight or low-porosity hair, the same coating builds up, and after two or three weeks the hair turns stiff, dry, tangled and snaps when you comb it. People call this protein overload. The name isn’t quite accurate, since starch is the main culprit, but the effect is real and it’s the most common reason rice water “didn’t work”.
The test is simple. Run a clean, dry strand between two fingers. Smooth and springy is fine. Straw-like, squeaky or crunchy means stop rice water for a month, wash with an ordinary shampoo, and use a plain conditioner on the lengths. The stiffness clears as the coating washes out.
Skip rice water altogether if you have a scalp condition such as psoriasis, seborrhoeic dermatitis or an active fungal patch; the starch feeds the flaking. Skip the face version if you have eczema or broken skin. And if your hair fall is heavy, sudden or patchy, rice water is a distraction from a cause a doctor needs to find, such as thyroid, low iron or a scalp infection.
The Yao women of Huangluo village in southern China are the famous example, with waist-length hair washed in fermented rice water for centuries. Closer to home, kanji (the water left from cooked rice) was poured over hair and used as a starch for saris, and the last rinse water from washing rice went onto plants and the doorstep, never down the drain. None of these households claimed regrowth. They claimed shine, and that claim holds.
Myth: rice water makes hair grow faster
Hair grows from the follicle under the skin, at about a centimetre a month, and a rinse sitting on the outside doesn’t reach it. What rice water can do is reduce breakage in hair that snaps easily, so more of the length you grow stays on your head. Over six months that can look like faster growth. It isn’t. The same honest logic applies to the “rice hack” drinks and weight claims that use rice water’s name; our rice water and rice hack verdict takes those apart separately.
Patch test both versions on the inner forearm and behind one ear, and wait 48 hours, before the first full use; fermented rice water in particular can sting or redden sensitive skin. Never use rice water that smells foul, fizzes, looks pink or grey, or shows fuzz, and never keep either version beyond 3 days in the fridge or a few hours out of it in summer. Keep it out of the eyes, and off broken or eczema-affected skin. If your scalp itches, burns or flakes more after a rinse, stop and wash with a plain shampoo. Rice water never replaces medical care for hair loss with bald patches, a scaly scalp, or hair coming out in clumps, and it never replaces sunscreen on the face. Ask a doctor about sudden hair fall rather than adding another rinse.
Rice water questions people search
How do you make rice water for hair growth?
Soak 100 g rinsed rice in 200 ml water for 30 minutes, strain, and use it as a 5 to 10 minute rinse after shampoo, once a week. Be honest with yourself about the “growth” part: it reduces breakage, which keeps length, but it doesn’t speed the follicle up.
Should rice water be fermented or plain?
Start plain. Fermented rice water is slightly acidic and some people find it smooths hair better, but it smells sour, stings sensitive skin, and needs diluting 1:1. Try plain for a month and only then decide whether fermenting adds anything for you.
How long can I keep rice water?
Three days in the fridge for plain or fermented. Out of the fridge, use plain rice water the same day. Throw away anything that smells foul, fizzes or grows fuzz.
How often should I use rice water on my hair?
Once a week. Twice at most, and only if your hair stays soft. More than that, and fine or low-porosity hair goes stiff from starch build-up.
Can I use rice water on my face every day?
Plain rice water on cotton wool once a day is fine for oily or normal skin after a patch test. Dry or eczema-prone skin usually feels tight and should skip it. It never replaces moisturiser or sunscreen.
Why does my hair feel stiff and dry after rice water?
Starch and protein build-up on hair that doesn’t need it, usually fine or low-porosity hair. Stop rice water for a month, shampoo normally, condition the lengths, and the stiffness clears.
Is rice water safe for children’s hair?
For a child over 5, a plain rinse is harmless, though unnecessary. Keep it out of the eyes. Skip the fermented version for children, and never put anything on a baby’s scalp without asking a doctor.
Can leftover rice water go on plants?
Yes, and that’s a better use for the fermented batch you didn’t like. Our rice water for plants verdict explains what it does and doesn’t do in the pot.
