Description
Rice water shampoo bar for thinning, shedding, or low-volume hair. This sulfate-free bar pairs rosemary and biotin with Longsheng rice water — the fermented rice water the Red Yao women of southern China are known for using in their hair care.
Rice water delivers amino acids, inositol, and antioxidants; hydrolyzed rice protein and biotin help strengthen the strand so fewer hairs break mid-length. Rosemary gives it a clean, herbal-green scent and antioxidant conditioning for the scalp. The result: hair that looks fuller and feels stronger, from a gentle wash you will actually enjoy.

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 and scalp thoroughly with warm water — not hot, which can further sensitize a reactive scalp.
2. Hold the bar in one hand and swipe it directly over your scalp in slow strokes, working section by section from the front hairline to the nape, until you feel lather building at the roots.
3. Set the bar aside and use your fingertips (not nails) to massage the lather gently into your scalp for 30–60 seconds — rosemary and peppermint are both studied for their role in supporting scalp circulation, and the massage itself encourages blood flow to the roots.
4. Work any remaining lather down the length of your strands with your hands, then rinse thoroughly until the water runs completely clear and no slipperiness remains.
5. If you are transitioning from a silicone-heavy or sulfate liquid shampoo, expect 2–3 washes for your scalp to recalibrate — any initial adjustment is a normal part of your scalp adapting to a formula without coating agents, not a reaction to the bar.
6. Store the bar on a draining soap dish between uses so it dries fully and lasts longer — a dry bar is a bar that earns its place on the shelf.
REAL RESULTS, REAL CUSTOMERS
Before and after
Real stories from three moms who made the switch.
"I was four months postpartum and pulling clumps off the drain cover every single shower. I didn't need a miracle — I needed something gentle that wouldn't add buildup to what little hair I had left. After two weeks with this bar, my scalp finally feels clean without that tight, stripped feeling. The shedding is still settling, but my roots have more lift than they've had since before I was pregnant."
"I live in a hard-water area and every silicone-heavy volumizing shampoo I tried left a film I could actually feel. I was reading INCI lists at midnight trying to find something I felt okay about while nursing — no sulfates, no synthetic fragrance, nothing I had to second-guess. This bar lathers clean and rinses completely. My scalp stopped feeling reactive after the first week, and I stopped dreading wash day."
"My hair is fine and straight, so anything heavy just plasters it flat. I wanted something that supported my scalp without coating the strands — and I wanted one bar on the shelf instead of three plastic bottles. The peppermint is noticeable in the best way, like my scalp can breathe again. It's the first part of my routine that actually feels like self-care instead of damage control."
VERIFIED REVIEWS FROM PEOPLE WHO HAVE BEEN THERE
WHAT THEY NOTICED IN THE SHOWER FIRST.
Verified reviews from people navigating postpartum shedding, sensitive scalps, and the search for a formula made without the ingredients they've been reading labels to avoid.
THE PROBLEM
Your Routine Wasn't Built For This.
The shampoos you trusted before pregnancy weren't formulated for a scalp that's shifted — or for a bathroom you're trying to keep clean and simple.
The Label Reads Like A Warning.
Sulfates, silicones, synthetic fragrance, parabens — you've been reading every INCI list, and most thinning shampoos are still full of the ingredients you're trying to avoid while nursing. You shouldn't have to choose between addressing shedding and trusting what's on your shelf.
Volume That Coats, Not Lifts.
Silicone-heavy volumizing shampoos can make hair look fuller in the short term by coating each strand — but that same buildup can weigh down roots that are already struggling and leave your scalp feeling congested and reactive. Your scalp is the soil right now; it needs to breathe, not be sealed.
Harsh shampoo makes fragile hair worse
Sulfates and heavy fragrance strip already-stressed hair, so more of it breaks mid-length and thin areas look even thinner. Hair can lose its natural softness and shine, making it appear dull and lifeless. Instead of looking fuller over time, it can become increasingly difficult to style and maintain volume.
THE ANSWER
Thoughtfully Formulated. Proven Effective.
The Rosemary Biotin Shampoo Bar is formulated for the scalp you have right now — reactive, tender, and doing the hard work of rebalancing after birth.
Longsheng rice water, rosemary leaf oil, and shea butter meet your scalp where it is: stripped of its pre-pregnancy equilibrium and sensitive to anything heavy or synthetic. The lather is rich, the rinse is complete — no silicone coating, no sulfate sting, no residue left behind to weigh down what little volume you're holding onto. Rosemary has been studied for its role in supporting scalp circulation, and biotin — a B-vitamin present throughout the formula — works alongside hydrolyzed rice protein and peppermint to nourish the root environment your hair is growing from. It's formulated without sulfates, parabens, synthetic fragrance, or phthalates, so you can stop reading the label and start using the bar. One hand, one bar, one less thing to figure out before the baby wakes up.

Backed by the science
WHY IT WORKS
Three ingredients. Three mechanisms. All aimed at the scalp — because that's where fullness begins.
-
Rosemary Feeds the Root
Rosemary leaf oil contains rosmarinic acid, ursolic acid, and carnosic acid — bioactive compounds studied for their antioxidant and anti-inflammatory properties that may help protect hair follicles from oxidative stress. Research suggests rosemary oil may support scalp circulation and extend the anagen (active growth) phase of the hair cycle. In a 2025 double-blind, randomized, placebo-controlled trial (90 participants, 90 days), a rosemary-lavender oil combination was associated with a significant reduction in hair fall and improvements in hair density compared to control — though that study examined androgenetic alopecia populations, not postpartum telogen effluvium specifically.
Patel et al. 2025 — Cureus / PMC12256010 -
Rice Water Repairs the Strand
Longsheng rice water — fermented, not plain starchy water — releases inositol (Vitamin B8) and panthenol (Vitamin B5) as its primary bioactive compounds. Inositol is identified in ingredient research as a key contributor to hair strengthening, while panthenol is studied for its role in supporting strand elasticity and may help reduce breakage along the hair shaft. Together with the hydrolyzed rice protein in this formula, they work to shore up hair that postpartum hormonal shifts have left more fragile and prone to snapping.

Sulfate-free cleansing preserves moisture in porous hair
Bleached hair is highly porous — it absorbs and loses moisture faster than untreated hair. Sulfate-free cleansers remove buildup and oil without disrupting the lipid layer that keeps moisture locked inside the shaft.

MADE FOR THE POSTPARTUM PHASE
What's happening to your hair — and what this bar can and can't do
Straight talk, because you have had enough vague promises. Here is the honest version.
What postpartum shedding is
During pregnancy, more of your hair stays in its growing phase. After birth, that hair sheds over a few months — often three to six. It is hormonal and temporary, and it typically settles on its own. No shampoo stops it, and anyone who promises to is overselling.
Where this bar helps
It focuses on what you can control—breakage and the new hair that's growing in. A gentle, sulfate-free formula with rice protein and biotin helps reduce breakage, so fewer hairs snap mid-length and your hair looks fuller and feels stronger. Reviewers call it the gentle, clean wash they reached for throughout this stage.
The formula is vegan and made without sulfates, parabens, phthalates, or synthetic fragrance. As with any personal-care product, check with your doctor or lactation consultant if you have questions.

FAQ
GOOD TO KNOW BEFORE YOU BUY.
It's a rinse-off shampoo bar: vegan, and formulated without sulfates, parabens, phthalates, or synthetic fragrance. We can't speak to any individual medical situation or make a safety claim, so please check with your doctor or lactation consultant if you have questions.
No product can stop hormonal postpartum shedding—it naturally runs its course over time. What this bar can do is gently cleanse and help reduce breakage, so the hair you have looks fuller and feels stronger. Pair it with our Viori Hair Vitamin to help support healthy hair from within.
Biotin is a well-known hair-care ingredient. In this bar it conditions alongside rice protein and amino acids to help hair feel stronger and look fuller, and to reduce breakage. It's not a growth drug — think stronger-feeling, fuller-looking hair, not a cure.
No. It rinses clean with no residue, and reviewers with fine hair report more body and lift at the roots, not buildup.
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.
It's a gentle daily wash, not a pill or a drug. It won't change your hormones; it helps the hair you have look and feel stronger. A lot of moms prefer a topical, clean wash over adding a supplement.
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.
There's a 30-day money-back guarantee, even if you've used the whole bar. Free shipping over $40, free returns.
