THE PROBLEM
Three things the "eco" shampoo aisle won't tell you
You've done the research. These are the patterns you keep finding.
The bottle habit
Every wash from a bottle is single-use plastic on a schedule — bought, emptied, replaced, forever. "Recyclable" doesn't stop the next one being made.
The greenwash filter
A leaf on the label, "eco" in the name — and "fragrance" hiding undisclosed synthetics in the ingredient list. You've learned to read past the front of the bottle.
The performance doubt
You've tried low-waste swaps that made you choose between your values and your hair. A bar that underperforms doesn't reduce waste — it becomes it.
THE ANSWER
A bar that removes the bottle — and holds up in the shower
No bottle, no pump, no cap — plastic-free bars and primary packaging. Every scent ingredient named (essential oils, no "fragrance" line). And underneath, fermented Longsheng rice water at pH 5.0–5.5: performance you can measure, not just believe.

Description
A rosemary shampoo bar with fermented Longsheng rice water and biotin — a plastic-free cleanse scented entirely with essential oils. A coconut-derived cleanser lifts oil and buildup at pH 5.0–5.5, rinsing clean in hard water with no film. Rice-water amino acids and inositol strengthen and soften the strand; biotin supports the appearance of thicker, fuller hair.* No sulfates, parabens, phthalates, or synthetic fragrance.

Ingredients Explanations
Sodium Cocoyl Isethionate — derived from coconut fatty acids; a mild, sulfate-free surfactant that cleanses without stripping a sensitive or reactive scalp. (EWG: 1)
Behentrimonium Methosulfate — plant-derived from rapeseed oil; a gentle conditioning agent that helps detangle without the silicone coating found in many volumizing shampoos. (EWG: 1)
Longsheng Rice Water — fermented rice water sourced from Longsheng, China; delivers amino acids, inositol, and antioxidants to support strand integrity along the length of the hair.
Cocoa Butter — cold-pressed from cacao seeds; provides rich emollient moisture to keep the bar's lather creamy and conditioning without heaviness. (EWG: 1)
Sodium Lactate — derived from the natural fermentation of sugars; helps maintain the bar's pH balance and supports scalp comfort. (EWG: 1)
Glycerin — plant-sourced humectant; draws moisture to the hair fiber and scalp surface to prevent dryness after cleansing. (EWG: 1)
Jojoba Oil — cold-pressed from jojoba seeds; structurally similar to the scalp's natural sebum, helping to condition without clogging or weighing roots down. (EWG: 2)
Cetyl Alcohol — derived from coconut or palm; a fatty alcohol that contributes to smooth, creamy lather — not a drying alcohol. (EWG: 1)
Shea Butter — cold-pressed from the shea tree nut; deeply nourishing for both scalp and strand, particularly supportive when skin feels reactive or tender. (EWG: 1)
Butylene Glycol (Plant-Based) — plant-derived solvent and humectant; helps ingredients blend evenly and supports moisture retention. (EWG: 1)
Stearic Acid — plant-derived fatty acid from vegetable oils; contributes to the bar's firm texture and helps condition the hair surface. (EWG: 1)
Hydrolyzed Rice Protein — broken-down rice protein; smaller molecular fragments associated with supporting body and reducing the appearance of thinning along the hair strand.
Broccoli Seed Oil — cold-pressed from broccoli seeds; rich in erucic acid, it imparts a natural slip and shine without silicone. (EWG: 1)
Bamboo Extract — derived from bamboo stem; a natural source of silica, associated with supporting hair fiber strength and resilience.
Rice Bran Oil — extracted from the outer bran layer of rice; rich in vitamin E and fatty acids that nourish the scalp and support a healthy environment for hair.
Vitamin B8 (Inositol) — a naturally occurring B-vitamin found in rice water and many plants; associated with supporting the structural integrity of the hair strand.
Vitamin B5 (Panthenol) — provitamin derived from plants; known to attract and retain moisture in the hair shaft, adding softness and reducing breakage-related shedding. (EWG: 1)
Rosemary Leaf Oil — steam-distilled from Rosmarinus officinalis; studied for its role in scalp circulation; may support the scalp environment as hair works to recover after hormonal shifts. (EWG: 1)
Biotin — a B-vitamin (B7) present in the formula; supports the keratin infrastructure of the hair strand as a nourishing ingredient. (EWG: 1)
Lavender Flower Oil — steam-distilled from lavender blossoms; contributes a calm, clean herbal note and has been studied for its soothing properties on sensitive skin. (EWG: 1)
Vitamin E (Tocopherol) — plant-derived antioxidant; helps protect the scalp and hair from oxidative stress and supports overall scalp comfort. (EWG: 1)
Marjoram Leaf Oil — steam-distilled from Origanum majorana; a gentle herbal oil that contributes to the bar's clean, earthy scent profile. (EWG: 1)
Roman Chamomile Flower Oil — steam-distilled from Anthemis nobilis flowers; known for its calming properties on reactive or tender skin. (EWG: 1)
Peppermint Leaf Oil — steam-distilled from peppermint; delivers a cooling, refreshing sensation on the scalp and has been studied for its role in supporting scalp circulation. (EWG: 1)
Lemongrass Leaf Oil — steam-distilled from Cymbopogon citratus; contributes a bright, clean note to the herbal scent and has astringent properties that support scalp balance. (EWG: 1)
Aloe Vera — cold-pressed gel from aloe leaves; deeply soothing for a sensitive or inflamed scalp, and helps maintain moisture without greasiness. (EWG: 1)
Plai Root Oil — steam-distilled from Zingiber cassumunar root; a Thai botanical known for its calming, anti-irritant properties on reactive skin. (EWG: 1)
Kunzea Oil — steam-distilled from Kunzea ambigua, a native Australian plant; studied for its soothing effect on sensitive skin and scalp. (EWG: 1)
Helichrysum Flower Oil — steam-distilled from Helichrysum italicum blossoms; associated with skin-calming and restorative properties, supporting a comfortable scalp environment. (EWG: 1)
How To Use
1. Wet your hair thoroughly — the more water, the better the lather from a bar format.
2. Rub the bar directly between your palms for a few seconds to build a light lather, or glide it along your scalp in short strokes from root to mid-length.
3. Work the lather into your scalp with your fingertips using circular motions — focus here, not on the ends, to help lift sebum and mineral buildup.
4. Rinse fully with warm water until your hair feels clear and your fingers move through it without resistance — this is what lathers clean, rinses clean, leaves nothing behind actually feels like.
5. If you're in the first 2–3 washes of switching from a liquid shampoo, expect a brief adjustment period as your scalp recalibrates; a second lather on wash day can help move things along faster.
6. Store the bar on a draining soap dish between uses — keeping it dry extends its life significantly and keeps it firm.

before & After
The Power of Plant-Based Ingredients
"I was so happy to find one that is color safe... my hair is still fresh looking as far as the color. I love how soft, shiny and thick my hair feels."
"After TWO uses my hair looks way healthier and feels softer than it has in a year. Even my husband noticed how shiny it was!"
"Nothing ever works on all of my hair — it's several different textures all mixed together. Now my hair feels soft all over and the frizzy bits are smoother than they've been in ages!"
Backed by the science
Low-waste that actually performs
The most common reason people go back to the bottle is a bar that didn't perform. This one isn't soap — a coconut-derived cleanser at pH 5.0–5.5 rinses clean in hard water. Fermented Longsheng rice water adds inositol and amino acids that strengthen and smooth, and gentler cleansing means less breakage during combing.

FAQ
GOOD TO KNOW BEFORE YOU BUY.
This isn't soap pressed into a bar — it's a coconut-derived cleanser (sodium cocoyl isethionate) at pH 5.0–5.5, the same slightly acidic range as healthy hair. It lathers, lifts oil and buildup, and rinses clean in hard water. In consumer testing across Viori bars, 92% felt softer hair after one wash (220-person panel).*
The bar and its box are plastic-free—and even the tape we use is plastic-free.
Fair question. Our formulas are biodegradable product compositions — designed to break down rather than linger — and every sustainability term we use is defined publicly on our claims page, so you can read exactly what we mean and where the limits are. No product is zero-impact.
No. While the name references rosemary and biotin, the formula is a gentle, pH-balanced everyday cleanse for all hair types — it isn't a treatment. This bar is for anyone cutting plastic out of their shower.

The shampoo bar cleanses and tones. The conditioner bar seals in the moisture and amino acids from the rice water and protects the cuticle between washes. For bleached hair — which is porous and loses moisture quickly — using both gives you the full repair benefit. The shampoo bar alone is a meaningful upgrade over a sulfate purple shampoo, but the duo is where the real difference shows.
Yes — most people need 2–3 washes for their hair to adjust from liquid shampoo to a bar formula. During that time your hair may feel slightly different as it clears out residue from previous products. Bleached hair typically adjusts faster than untreated hair because the cuticle is already more open. Stick with it past the first wash.
Each bar lasts 60–80 washes, which is the equivalent of 2–3 bottles of liquid shampoo. The bar stays dry between uses when stored on a bamboo holder with airflow drainage, which extends its life significantly. If you are washing 2–3 times a week, one bar typically lasts 5–8 months.
