Rice water for hair has become a viral topic among hair care enthusiasts looking for a more natural approach to achieving stronger, shinier locks. Some users praise it for reducing frizz, while others believe it supports healthier growth. If you’ve been curious about this starchy liquid and its possible effects, you can find more details about its growth-boosting potential by reading our rice water for hair growth guide.
What Is Rice Water?
Rice water is the leftover liquid from soaking, boiling, or fermenting rice. It’s rich in vitamins, minerals, amino acids, and antioxidants. Historically, cultures in China and Japan have used it to maintain long, glossy hair. A well-known example comes from the Yao women of Huangluo village in China, often celebrated for their floor-length hair.
According to a 2024 study published in the Journal of Emerging Technologies and Innovative Research, fermented rice water may also inhibit the growth of dandruff-causing fungi. Meanwhile, some users simply appreciate its smoothing properties.
Key Nutrients in Rice Water
This cloudy liquid offers more than just starch. Rice water contains eight essential amino acids, several B vitamins, and vitamin E. It’s also believed to hold inositol, a carbohydrate that can penetrate the hair shaft and help reinforce damaged strands.
According to a systematic review published in the Journal of Drugs in Dermatology in 2022, rice bran extract—found in certain rice water preparations—appears to boost the production of signals linked to the active growth phase of hair. These signals may contribute to healthier-looking hair over time.
Another interesting point is the close-to-balanced pH. Rice water typically ranges from 4.5 to 6.5, which is fairly similar to the natural pH level of your scalp. This alignment could reduce scalp irritation and help maintain a better overall environment for your roots.
How to Make Rice Water
There are three primary ways to prepare rice water. Each method produces slightly different nutrient levels, but all can be done with common kitchen tools.
Soaking Method
This approach is simple and beginner-friendly. Rinse around half a cup of uncooked rice (white, brown, or even red rice). Place the rice in a bowl with two to three cups of water. Let it soak for 30 minutes, then strain the liquid into a separate container. Some people use this mild version as a weekly rinse.
Boiling Method
If you prefer a more concentrated rinse, try boiling. Rinse half a cup of rice and put it into a pot with about two cups of water. Let it simmer until the water looks cloudy. Once it cools, strain the water and store it in a clean jar or container.
Fermenting Method
Fermentation produces a potent liquid with higher antioxidant levels. Start with either soaked or boiled rice water and leave it at room temperature for up to two days. A slightly sour scent means it has fermented. Strain and keep this liquid refrigerated. Fermented rice water often has a lower pH, making it more closely aligned with your hair and scalp.
Benefits of Rice Water for Hair
Individuals from different backgrounds have credited rice water with various positive effects. While you might discover subtle differences based on your hair texture or how often you apply it, several consistent benefits often come up.
Strength and Elasticity: The amino acids in rice water, including cysteine, can support your hair’s protein structure. A 2010 study in the Journal of Cosmetic Chemists noted that treatments containing rice extracts reduce friction between strands, which may lessen breakage.
Added Shine: Many people say the starchy coating left behind on each strand boosts reflection, creating a visible gleam. This coating also helps your strands lay flatter, potentially minimizing frizz.
Scalp Health: The pH range of rice water often complements the scalp’s natural acidity. A balanced scalp environment reduces dandruff risk. Some sources highlight that fermented rice water can help limit the growth of Malassezia fungus.
Detangling and Manageability: The silky texture can serve as a natural detangler, especially if your hair is prone to knots. Smoother hair tends to be more manageable and requires less tugging with a brush or comb.

Application Tips and Frequency
The big questions are usually: How often should you use rice water, and how long should you leave it on? Although there’s no one-size-fits-all answer, consider starting with once or twice a week. Then adjust based on how your hair responds.
If you choose a simple rinse, apply it right after shampoo and let it sit for about 10 to 20 minutes. Massage gently from the scalp down to the ends and rinse with warm water. For a leave-in approach, you can work a small amount into wet, freshly cleansed hair, though people with dry strands might need extra moisture afterward.
Some prefer a deep-conditioning mask. In that scenario, coat your hair thoroughly and keep it covered for up to 30 minutes before rinsing. The extended exposure helps the amino acids absorb, but be mindful of potential protein buildup.
Potential Side Effects
Every hair type differs, so pay attention to how your hair reacts to frequent treatments. Although most people tolerate rice water without issue, certain side effects can pop up.
- Protein Sensitivity: Overusing protein-rich treatments can make hair feel stiff or cause breakage in protein-sensitive types.
- Scalp Build-Up: Extra starches may linger, leading to itchiness or flaky spots if not rinsed properly.
- Allergic Reactions: Although rare, test on a small patch of skin first if you’re uneasy about potential irritation.
A dermatologist at the University of Minnesota, Dr. Ronda Farah, cautions that the starch in rice water could draw moisture away from hair, especially tightly coiled or brittle strands. Balance it with hydrating products to reduce dryness.
Additional Tips for Different Hair Types
Fine or oily hair may do best with a quick rinse. Too much protein-heavy liquid can weigh the strands down. Curly or coiled hair might benefit from a more moisturizing approach, such as diluting the rice water or pairing it with your favorite conditioner.
Some people add aloe vera or a few drops of essential oils—like lavender or rosemary—for added conditioning or fragrance. Alternatively, you could compare its effects with other floral-based rinses, such as rose water, if you enjoy experimenting with different DIY products.
If you have color-treated or chemically lightened hair, start slowly. Test the soak or rinse on a small section to see if any extra dryness develops. Adjust how frequently you apply it to avoid excessive protein buildup.
Common Questions
Does it promote growth? While there’s no definitive proof that rice water directly causes hair to grow faster, many of its nutrients support overall hair resilience. A stable environment can affect growth indirectly by reducing breakage.
How quickly will I see results? Observations vary. Some folks notice smoother texture within a few weeks, but visible changes in length or thickness can take months. Consistency tends to make the most difference.
Is it safe for everyone? Most hair types handle it well, but overuse can lead to brittleness. Start with small amounts and adjust based on how your hair looks and feels.
Can I store it? Yes. Keep leftover soak or boiled versions refrigerated for up to five days. Fermented rice water can last a bit longer, but discard at the first sign of an off odor beyond its typical sour smell.
Bottom Line
Rice water offers a budget-friendly way to try a natural hair rinse, tapping into a long history of tradition. From potential breakage reduction to possible shine enhancement, this starchy potion has found its place among DIY hair care enthusiasts. If you’re curious about tailored approaches for curly textures, you might find more details on using rice water for curly hair very helpful.
As always, keep an eye on how your hair responds. If you detect any stiffness or dryness, scale back and mix in extra moisture. With a bit of testing, you could discover a simple hair care addition that might leave your hair feeling smoother and looking healthier.
