Every day, millions of people rinse away something that could transform their beauty routine without spending a single extra dollar. That cloudy water left after soaking rice isn’t waste—it’s been used for centuries in Asia for glowing skin and stronger hair. Yet most of us pour this liquid gold straight down the drain.
The craziest part? Modern studies are now confirming what grandmothers in Japan and Korea have known for generations. But here’s the thing most articles won’t tell you: there’s a right way to prepare and use rice water to actually see results… and a way that does almost nothing. Keep reading, because the most powerful method is probably not the one you’ve seen on TikTok.
What Exactly Is Rice Water and Why Does It Work?
Rice water is simply the starchy liquid left behind after soaking or cooking rice. This milky substance contains an impressive array of nutrients that remain after the rice itself is removed.
Research has identified several compounds that make rice water particularly interesting for hair and skin:
- Inositol, a carbohydrate that studies show can help repair damaged hair
- Amino acids that support collagen production
- Ferulic acid, a powerful antioxidant
- Trace minerals including magnesium and selenium
- Small amounts of vitamins B and E
A 2018 study published in the Journal of Cosmetic Dermatology noted that rice water appears to improve hair elasticity and reduce surface friction. Another study from 2013 found that the antioxidants in rice water help protect skin from sun damage when used topically.
But here’s what really matters: not all rice water is created equal.
The 3 Different Types of Rice Water (Most People Choose the Wrong One)
There are actually three distinct methods to make rice water, and each produces very different results:
- Rinsing Method (Quick Version) Simply rinse rice and collect the cloudy water. This is the fastest method (2-3 minutes) but contains the lowest concentration of beneficial compounds.
- Soaking Method (Most Popular) Soak rice in water for 30 minutes to 24 hours. This extracts more nutrients and creates the classic milky appearance most people recognize.
- Fermented Rice Water (The Secret Weapon) Let soaked rice water sit at room temperature for 24-48 hours until it develops a slightly sour smell. This fermentation process changes the pH and dramatically increases the concentration of antioxidants and pH-lowering compounds.
Traditional Japanese women from the Heian period (over 1000 years ago) used fermented rice water exclusively. Modern research suggests they were onto something—fermentation can increase antioxidant levels by up to 10 times compared to regular rice water.
How to Make Perfect Fermented Rice Water at Home (Step-by-Step)
Here’s the exact method that gives the best results according to both traditional practice and current research:
Step 1: Use organic rice when possible (white, brown, or jasmine all work well)
Step 2: Rinse ½ cup of rice thoroughly to remove any dirt or impurities
Step 3: Place the rinsed rice in a clean bowl and add 2-3 cups of filtered water
Step 4: Stir vigorously for 2-3 minutes until the water becomes cloudy white
Step 5: Strain the rice (save it for cooking!) and pour the cloudy water into a clean glass jar
Step 6: Cover loosely and let sit at room temperature for 24-48 hours
Step 7: You’ll know it’s ready when it smells slightly sour (like yogurt) but not unpleasant
Step 8: Store in the refrigerator—it will keep for up to 7 days
Pro tip: The longer you ferment (within reason), the stronger the effects. Some people go up to 72 hours for maximum potency.
7 Powerful Ways to Use Rice Water (Backed by Experience and Research)
1. As a Hair Rinse for Stronger, Shinier Hair
After shampooing, pour fermented rice water over your hair and massage into the scalp. Let it sit for 20 minutes before rinsing with plain water. Many people notice significantly less hair fall after just 2-3 uses.
2. As a Face Toner for Brighter Skin
Store rice water in a spray bottle and use it as a daily toner after cleansing. The natural starches help tighten pores, while the antioxidants provide gentle protection throughout the day.
3. In Your Bath for Full-Body Softness
Add 2-3 cups of rice water to your bath for incredibly soft skin. This is how Japanese geisha maintained their famous porcelain complexions.
4. As a Gentle Face Wash
Use diluted rice water (1 part rice water to 2 parts regular water) as a morning cleanser. It’s especially helpful for sensitive skin that reacts to commercial products.
5. For Soothing Irritated Skin
The anti-inflammatory properties make rice water excellent for calming redness and irritation. Keep a bottle in the fridge for instant cooling relief.
6. As a Hair Detangler
Spray diluted rice water on tangled hair before combing. The natural coating makes hair glide through brushes effortlessly.
7. Mixed with Your Favorite Mask
Add rice water to clay masks, honey masks, or any DIY treatment for an extra boost of nutrients.
How Often Should You Use Rice Water?
Start slowly to see how your hair and skin respond:
- Hair: 1-2 times per week (too much can make hair feel stiff)
- Face: Daily as toner, or 3-4 times per week as wash
- Bath: Once per week for a luxurious treat
The key is consistency. Most people notice visible differences after 3-4 weeks of regular use.
Common Mistakes That Make Rice Water Completely Ineffective
- Using the quick rinse method and expecting dramatic results
- Not fermenting when you want maximum benefits
- Leaving rice water on hair without rinsing (can cause buildup)
- Using rice that’s been treated with synthetic vitamins/enrichments
- Storing improperly (always refrigerate after fermentation)
The Simple Truth Most Beauty Companies Don’t Want You to Know
That $80 “miracle” hair treatment gathering dust in your bathroom probably contains less active ingredients than the rice water you made in your kitchen for free.
Traditional wisdom, when combined with modern understanding, often beats expensive products. Rice water isn’t magic—it’s just nature working exactly as intended.
Frequently Asked Questions
Is rice water safe for all hair types? Yes! It’s particularly beneficial for damaged or dry hair, but even oily hair types can use it (just rinse thoroughly).
Can I use rice water every day on my face? Most people can, especially when diluted. Start with every other day to see how your skin responds.
Does the type of rice matter? Organic is best, but any rice works. Brown rice contains more nutrients but may be slightly more irritating for very sensitive skin.
How long does homemade rice water last? Plain (non-fermented) lasts 3-4 days in the fridge. Fermented lasts up to 7 days and actually gets stronger as it sits.
