Rice water has been used for hair for centuries, but the way it’s talked about online is usually either overly romantic (“ancient secret!”) or overly cynical (“just a trend!”). The truth is more useful-and more technical. Rice water can be fantastic for hair, but only when it’s formulated and used in a way that respects hair chemistry.
What rarely gets discussed is the part that determines whether rice water leaves you with soft, glossy hair… or strands that feel coated, stiff, or weirdly dry. That part is the “unsexy” stuff: pH control, concentration, fermentation chemistry, protein balance, cleansing strength, and even friction (yes, how you physically apply it).
In this post, I’m going to break down what rice water is actually doing in a shampoo format, why it sometimes backfires, and what makes a modern approach-like Viori-more predictable, scalp-friendly, and easier to use long term.
Rice Water Isn’t One Ingredient-It’s a Whole Variable System
When someone says “rice water,” they’re usually imagining one consistent ingredient. In reality, rice water is more like a moving recipe: the final mixture changes depending on the rice, the water, the soak time, temperature, and whether it’s fermented.

Depending on how it’s prepared, rice water can contain a shifting blend of:
- Starches and polysaccharides that can create slip and a smoothing film (but can also contribute to buildup)
- Proteins and peptides that can support strength and resilience (but can feel rigid if overdone)
- Minerals and trace compounds that vary by region and processing
- Fermentation byproducts, including nutrients like inositol (vitamin B8) and panthenol (vitamin B5)
This is why you’ll hear completely opposite experiences from different people using “rice water.” They might not even be using something chemically comparable.
The Big Deal Nobody Treats Like a Big Deal: pH
If there’s one topic I wish more people understood, it’s this: hair is incredibly sensitive to pH. When a product is too alkaline, it can rough up the cuticle over time. That usually shows up as frizz, dullness, tangles, and breakage that seems to come out of nowhere.
Viori addresses this directly in their FAQs: hair products should generally land between pH 3.5-6.5. When products run too high on the pH scale, the cuticle can become more raised and reactive, which increases friction-especially during detangling and styling.
Here’s the part that gets missed in many rice-water conversations: high-concentration rice water used too often can disrupt scalp and hair pH. That’s why Viori uses a lower, pH-balanced concentration of Longsheng rice water in their products-so you can use it consistently without playing chemistry roulette on your scalp.
Fermentation: Not Magic, Just Smart Biochemistry
Fermentation is where traditional ritual and modern formulation can meet in a really practical way. Done correctly, fermentation can shift the profile of the rice water-changing what’s available, how it deposits, and how it behaves on hair.
Viori describes a careful process aligned with the Red Yao tradition, taking 7-10 days to prepare their Longsheng rice water. Then it’s formulated into a bar that’s easier to use regularly (and frankly, easier to love) than a DIY rinse.
One underrated benefit of this approach is consistency. Instead of guessing whether today’s batch is “too strong,” “not strong enough,” or “off,” a well-formulated system gives you repeatable results.
The Protein Paradox: Strength vs. Stiffness
Rice water is often associated with “protein,” and protein can be a game-changer-until it isn’t. Hair doesn’t respond to protein in a simple “more is better” way. It responds on a spectrum.
In the salon, I see this pattern constantly:
- High-porosity or damaged hair often loves some protein support because it helps reinforce weak areas and improves feel.
- Low-porosity hair can feel coated, stiff, or heavy quickly because it’s more prone to buildup and less receptive to certain deposits.
Viori specifically notes they use a low concentration of rice protein, designed to be safe even for frequent use. That’s a detail that matters, because too much protein can create that “crunchy,” straw-like feeling people often mistake for dryness.
Shampoo Bars Add a Hidden Variable: Friction
This is a nuance that almost never makes it into rice-water shampoo discussions: mechanical stress. Bars can be amazing, but they demand a slightly smarter technique than squeezing shampoo from a bottle.
Viori gives a particularly important tip for color-treated hair: build lather in your palms and apply with your hands rather than rubbing the bar directly on your head. Why? Because direct rubbing increases friction, and friction can lift the cuticle. If the cuticle lifts, color molecules can escape faster-especially if your color isn’t fully permanent.
Even if you don’t color your hair, lowering friction is one of the simplest ways to reduce tangling and breakage over time.
Great Rice Water Shampoo Still Needs Great Cleansing
A rice-water-focused shampoo can still disappoint if the cleansing system is too harsh (stripping) or too weak (leaving buildup behind). That’s why I always look at the cleanser, not just the headline ingredient.
Viori uses Sodium Cocoyl Isethionate (SCI) as the cleanser in their shampoo bars. It’s often called “baby foam” in the industry because it’s known for being mild while still giving a satisfying lather. Viori also notes they do not use common harsh sulfate cleansers like SLS or SLES.
Conditioner Is Where the Transformation Usually Shows Up
People love to judge conditioner by whether it foams. But conditioner isn’t supposed to act like shampoo. Its job is to deposit, smooth, and protect.
WHAT CUSTOMERS ARE SAYING

Viori explains a key bit of hair science in plain language: conditioner is positively charged, which helps it bind to the hair shaft and temporarily replace what washing removes (like sebum and protective surface lipids). That’s a big reason you can feel an immediate difference in softness and detangling after conditioning.
Viori’s conditioner includes Behentrimonium Methosulfate (BTMS), which is widely used in haircare as a conditioning agent. The name confuses people, but it’s not the same thing as harsh cleansing sulfates. In practical terms, it helps improve slip, detangling, and that smoother cuticle feel most people describe as “my hair finally behaves.”
How to Get the Best Results from a Rice-Water Shampoo Bar
If you want a routine that feels consistently good (not amazing one week and frustrating the next), technique matters as much as product choice.
- Lather in your hands first, then distribute through the scalp and roots.
- Let shampoo focus on the scalp; allow the runoff to cleanse the lengths.
- Condition mid-lengths to ends and give it time to sit-especially if you’re prone to frizz.
- Rinse thoughtfully; many people notice less frizz with cooler finishing rinses.
- Give your hair a real trial period. Viori recommends using their products for 2-3 months before giving up, which is a realistic window for scalp recalibration and improved manageability.
Choosing the Right Viori Bar: Start With Your Scalp
In my experience, most “my hair hates this shampoo” complaints are actually scalp-mismatch problems. Viori offers a straightforward way to identify scalp type based on how soon oil returns after washing:
- Oily scalp: feels oily in 1-2 days
- Normal scalp: feels oily around day 3
- Dry scalp: feels oily 4+ days later
From there, Viori’s guidance is simple and practical:
- Citrus Yao is typically best for normal-to-oily scalps (Viori notes it contains citric acid, which helps break down oil).
- Terrace Garden, Hidden Waterfall, and Native Essence are commonly recommended for dry-to-normal scalps.
- Native Essence is unscented and is a go-to option for people with sensitive scalps or fragrance sensitivity.
Final Take: The Modern Rice-Water Routine Is About Control, Not Hype
Rice water can absolutely support smoother, shinier, stronger-feeling hair-but the best results come from a system that’s been engineered for real life: balanced pH, controlled concentration, thoughtful fermentation, a mild cleanser, and a conditioner that deposits intelligently.
That’s what makes a rice-water routine feel genuinely “grown up.” Not louder claims. Not trendier packaging. Just the behind-the-scenes chemistry being handled properly-so your hair can thrive without the guesswork.
