Rice Water Rice Oil Hair Treatments: How to Make Both at Home
Both are kitchen cheap, both take under an hour, and one of them is far easier to get wrong.
A rice water rice oil hair routine uses two different things made from the same grain. Rice water is the starchy soaking liquid, used as a rinse for slip and temporary body. Rice bran oil is pressed from the husk and used as a conditioning oil. Rice water suits hair that feels soft and limp. Rice oil suits hair that feels dry, rough or over proteined.
Key takeaways
- Rice water and rice oil do close to opposite jobs. Using both blindly is how people end up with brittle hair.
- Rice water is a rinse. Leave it on for 5 to 20 minutes, then rinse it out, and never leave it in overnight.
- Fermented rice water is more acidic and stronger smelling. Ferment for 12 to 24 hours at room temperature, not days.
- True rice bran oil is pressed, not infused. What you make at home is a rice infused oil, which is a milder thing.
- Rice water keeps 4 to 5 days refrigerated. Home infused oil keeps 6 to 12 months in dark glass.
- Evidence for either on hair is thin. Expect cosmetic slip, shine and manageability rather than a change in density.
What is the difference between rice water and rice oil?
They come from the same plant and behave completely differently, which is the single most useful thing to understand before you make either.
| Rice water | Rice oil | |
|---|---|---|
| What it is | Starchy water from soaking or rinsing rice | Oil pressed from rice bran, or rice infused into a carrier |
| Main effect | Coats the fibre, adds temporary body and slip | Softens, adds shine, reduces friction |
| Best for | Limp, soft, over conditioned hair | Dry, rough, coarse or brittle hair |
| How often | Once a week at most, some people once a fortnight | Once or twice a week as a pre wash |
| Gets it wrong how | Too often or left on too long, giving straw like stiffness | Too much, giving limp greasy roots |

How do you make rice water for hair, step by step?
Three versions exist, in ascending order of strength. Start with the first.
Plain soaked rice water (mildest)
- Rinse half a cup of uncooked rice under the tap to wash off dust. Discard that first rinse.
- Cover the rice with two cups of clean water and leave it for 30 minutes at room temperature.
- Strain the liquid into a clean jar. Cloudy is correct.
- Use within 4 to 5 days and keep it in the fridge between uses.
Boiled rice water (stronger, faster)
- Cook half a cup of rice in three cups of water until soft.
- Strain the cooking water off and let it cool completely.
- Dilute it, roughly one part rice water to one part plain water, because it comes out much more concentrated.
Fermented rice water (strongest, and the one people overdo)
- Make plain soaked rice water as above.
- Leave the strained liquid at room temperature for 12 to 24 hours until it smells faintly sour.
- Refrigerate immediately. Ferment for days rather than hours and you get something genuinely unpleasant, not something stronger.
- Dilute before use, and consider adding a few drops of an essential oil for the smell.
How do you make rice oil at home, and what are you really making?
Worth being precise here, because the two things sold under the name are not the same. Commercial rice bran oil is mechanically pressed from the bran layer, which is where the oil actually lives. You cannot press oil out of rice in a domestic kitchen. What a home method produces is a rice infused oil, where a carrier oil picks up some of the lipids and antioxidants from toasted rice or rice bran.
That is still a perfectly nice conditioning oil. It is just a milder thing than the bottle in the supermarket, and it is honest to say so.
The warm infusion method
- Toast half a cup of rice, or better, rice bran if you can get it, in a dry pan over low heat for a few minutes until it smells nutty. Do not brown it.
- Put the toasted rice in a heatproof bowl and cover with 250ml of a carrier oil. Fractionated coconut, jojoba or sweet almond all work well.
- Set the bowl over a pan of barely simmering water and hold the oil between 50 and 70 degrees Celsius for two to three hours. It should never bubble or smoke.
- Cool, strain through muslin, and bottle in dark glass away from light and heat.
- Use within 6 to 12 months, and discard it if it ever smells sharp or like old crayons.
The same principle applies to any botanical infusion, and the method is identical to the one in our guide to making horsetail oil. Dry ingredients, dry jar, everything under the oil line.
Which rice water rice oil hair treatment should you make first?
Answer one question at the sink. Does your hair feel too soft, limp and shapeless, or does it feel rough, dry and prone to snapping?
- Too soft and limp: start with rice water. The starch coats the fibre and gives temporary body, and hair that has been over conditioned often responds well.
- Rough, dry or brittle: start with rice oil. Adding more protein like material to hair that is already stiff makes it worse, not better.
- Genuinely unsure: start with the oil. It is much harder to cause a problem with a pre wash oil than with a repeated protein rinse.
People with low porosity hair should be especially careful with the rinse, because the cuticle already resists absorbing things and product tends to sit on the surface. Our guide to rice water and low porosity hair goes into that properly.

What does the evidence actually show?
Less than the internet suggests, and it is worth being straight about that before anyone builds a whole routine on it.
There is no published controlled trial showing that rice water grows hair. The most commonly cited support is laboratory work on inositol, a carbohydrate present in rice, which reported that it remains on the fibre after rinsing and appeared to reduce friction. That is a cosmetic surface effect on the hair shaft, and it is a long way from a growth claim. The frequently repeated story about the Yao women of Huangluo is cultural observation rather than a study, and their hair length is at least as likely to reflect genetics and the fact that they rarely cut it.
Rice bran oil has better established credentials as an emollient. It contains oryzanol, tocopherols and tocotrienols, which are genuine antioxidants, and it behaves like other light plant oils on hair: reduced friction, better slip, more shine.
So the fair summary of a rice water rice oil hair routine is that it is a low cost cosmetic experiment with a plausible surface mechanism and no meaningful risk if used sensibly. That is a reasonable thing to try. It is not a density solution.

Hair loss, hair shedding or hair breakage: which one sent you to the rice?
Worth separating, because rice helps with exactly one of the three.
- Hair loss means the follicle itself is affected, as in androgenetic alopecia or alopecia areata. Density falls in a pattern or in patches. No kitchen rinse changes this, and it belongs with a GP.
- Hair shedding means the cycle has been disturbed, as in telogen effluvium after illness, childbirth or a stressful period. Follicles leave the anagen phase early and release together about three months later. Time and correcting the trigger are what resolve it.
- Hair breakage means the fibre is snapping mid length, leaving short pieces of uneven length with white ends. Heat, bleach, tight styling and rough detangling cause it.
Breakage is the one where an oil or a rinse genuinely earns its place, because both reduce friction and friction is what snaps strands during combing and towel drying. If the problem is density rather than length, rice is the wrong shelf entirely.
What are the common mistakes with rice water and rice oil?
- Using rice water too often. Once a week is the ceiling for most people, and once a fortnight suits many. Repeated protein type rinses on hair that does not need them produce stiffness and snapping.
- Leaving it on overnight. Never necessary, and the main cause of the straw like results people complain about.
- Skipping conditioner afterwards. Always follow a rinse with a proper conditioner. Our guide on how to use conditioner properly covers the technique.
- Fermenting for days. 12 to 24 hours. Past that you are culturing something you do not want near your scalp.
- Keeping it too long. Rice water is a fresh food product. Four to five days refrigerated, then make more.
- Applying oil to the roots when the problem is at the ends. Mid lengths and ends for oil, scalp only if you are doing a deliberate pre wash massage.
If the infusion project sounds like more effort than you want, this does the same pre wash job without a jar on the shelf. Camellia and black castor for slip and shine, so a comb moves through without snapping strands.

Frequently asked questions
What is the difference between rice water and rice oil for hair?
Rice water is the starchy soaking or cooking liquid, used as a rinse that coats the fibre and gives temporary body and slip. Rice oil is pressed from the bran, or infused at home into a carrier oil, and it softens and adds shine. In a rice water rice oil hair routine they do close to opposite jobs, so pick the one your hair actually needs.
How long should you leave rice water on your hair?
Between 5 and 20 minutes, then rinse thoroughly and follow with conditioner. Leaving it on overnight is the most common cause of the stiff, straw like results people report.
How often should you use rice water?
Once a week at most, and once a fortnight suits plenty of people. Repeated protein type rinses on hair that does not need them cause stiffness and snapping rather than strength.
How long does rice water keep?
Four to five days in the fridge. It is a fresh food product, so make a new batch rather than stretching an old one.
Can you make real rice bran oil at home?
No. Commercial rice bran oil is mechanically pressed from the bran layer, which is not achievable in a domestic kitchen. What you make at home is a rice infused oil, milder but still a perfectly good conditioning oil.
Does rice water grow hair?
There is no published controlled trial showing that it does. Laboratory work on inositol points to a surface effect that reduces friction on the fibre, which is cosmetic rather than a change in growth.
Should you ferment it?
Only if plain rice water has not done much, and only for 12 to 24 hours at room temperature before it goes into the fridge. Longer does not mean stronger.
Can you use both in the same week?
Yes, and for most people that is the sensible version of a rice water rice oil hair routine: the oil as a pre wash treatment on the ends, the rinse after shampooing, and a conditioner after the rinse. Just do not stack a protein rinse onto hair that already feels stiff.

The short version
Make the oil if your hair is dry and rough. Make the rinse if it is soft and limp. Rice water is a five to twenty minute rinse that lives in the fridge for under a week, rice oil is a warm infusion that lives in dark glass for months, and neither is a density solution. Used with a bit of judgement, a rice water rice oil hair routine is a cheap, pleasant way to get more slip and shine out of the hair you already have.
