You’ve probably seen the videos. Someone pours cloudy rice water over their hair, and a few months later, their hair is down to their waist.
It’s cheap, it’s natural, and it’s everywhere on social media. But does rice water really make your hair grow? Or is it just another trend?
Rice water may make hair feel smoother and look shinier for some people, mostly because its starch coats the hair. But there’s no solid proof that homemade rice water makes hair grow faster or longer. The only human study often mentioned used a special rice bran extract, not the rice water you make at home. It’s generally safe to try, but it can dry out some hair and cause buildup.
Below, we break down what the research says, who might benefit, the risks, and how to try it safely.
What Is Rice Water?
Rice water is the starchy, cloudy water left after you soak or boil rice. There are two main types:
- Plain rice water: made by soaking or boiling rice.
- Fermented rice water: rice water left at room temperature for a day or two until it turns slightly sour.
It contains starch, small amounts of amino acids, vitamins, and inositol, a compound often linked to hair health in marketing claims.
Where Did the Hype Come From?
The trend is often linked to women of the Yao community in China, known for their very long hair and their tradition of washing with fermented rice water.
It’s a beautiful tradition, but long hair in any community usually comes from many factors: genetics, gentle care, rarely cutting it, and protecting the ends. Rice water alone isn’t proven to be the reason.
What Does the Research Say?
Here’s the honest picture:
| Claim | What the evidence shows |
|---|---|
| Makes hair grow faster | No good evidence for homemade rice water |
| Thickens hair | One human study used a rice bran extract product, not DIY rice water |
| Makes hair shinier and smoother | Possible, mainly from starch coating the hair |
| Strengthens hair | Mostly lab and animal studies, not real-world human proof |
| Safe to use | Generally safe on the scalp, but can dry out some hair |
The study people often talk about
A 2022 review in the Journal of Drugs in Dermatology looked at 10 studies on rice products for hair. Only one was in humans. It was a 2015 trial of 50 people with hair loss who used a rice bran extract product twice a day for 16 weeks. That group had denser, thicker hair than the placebo group.
But dermatologists point out two important things:
- The study used a rice bran extract, which is mostly removed when rice is milled. The white rice in your kitchen doesn’t contain much of it.
- Using a product twice a day for 16 weeks is very different from rinsing your hair with rice water once a week.
The bottom line on growth
Rice water won’t change how fast your hair grows. Hair growth is mainly controlled by genetics, hormones, age, and overall health. On average, hair grows about half an inch a month.
Possible Benefits (What Rice Water Might Do)
- Smoother feel: Starch can coat the hair and make it feel slicker.
- More shine: A smoother surface can reflect more light.
- Less friction: Smoother hair may tangle a little less.
- A nice ritual: Some people simply enjoy it as part of their routine.
These effects are mostly temporary and cosmetic. They wash away like any other rinse.
Possible Downsides and Risks
- Dryness: Dermatologists note that the starch can pull moisture from hair, which may leave it dry or brittle, especially if your hair is already dry or damaged.
- Buildup: Starch can leave a film on hair and scalp if not rinsed well.
- Stiff or crunchy hair: Some people find their hair feels rough after using it often.
- Scalp irritation: Rare, but possible, especially with sensitive skin, eczema, or psoriasis.
- Bacteria in fermented rice water: Leaving rice water out too long can grow unwanted bacteria and smell bad. Keep it short and clean.
- Low-quality products: Some store-bought products may contain irritating fragrances.
Who should skip it: People with very dry, damaged, or bleached hair, and anyone with eczema, psoriasis, or a sensitive scalp.
How to Use Rice Water Safely (If You Want to Try It)
How to make it
- Rinse ½ cup of uncooked rice to remove dirt.
- Soak it in 2 cups of clean water for 30 minutes, stirring now and then.
- Strain the water into a clean jar.
- (Optional, fermented) Leave the jar covered at room temperature for 12–24 hours, then refrigerate. Use within a few days.
How to use it
- Shampoo your hair as usual.
- Pour or spray rice water over your hair and scalp.
- Leave it on for 5–10 minutes. Don’t leave it on for hours.
- Rinse thoroughly with water.
- Follow with a moisturizing conditioner, since rice water can be drying.
How often
Once a week is plenty to start. Watch how your hair feels. If it gets dry or stiff, use it less or stop.

Store-Bought Rice Water Products
If you don’t want to DIY, many shampoos, conditioners, and rinses include rice water or rice protein. They’re more convenient and less messy, and they’re usually formulated with moisturizers to balance the starch. Choose fragrance-free options if your scalp is sensitive.

What Actually Helps Hair Grow Longer
If your real goal is longer, healthier hair, these habits matter more than rice water:
- Prevent breakage with gentle brushing, a wide-tooth comb, and silk pillowcases.
- Use heat protectant and lower heat.
- Trim split ends regularly so they don’t travel up the hair.
- Moisturize with conditioner and a weekly mask.
- Eat a balanced diet with enough protein, iron, and vitamins.
- Manage stress, which can trigger extra shedding.
- See a dermatologist if you’re losing hair. Treatments like minoxidil have real clinical evidence for hair loss.
