Rice water shampoo bar for fine, flat, or low-volume hair. This sulfate-free shampoo bar pairs rosemary and biotin with Longsheng rice water — the same fermented rice water the Red Yao women of southern China are known for using as their primary hair care treatment. Biotin supports the look of thicker, fuller strands. Rice water delivers amino acids, inositol, and antioxidants that condition the strand and support stronger-looking hair with less breakage.* Together they help fine hair look fuller and feel stronger — without weighing it down. Scent: Herbal and green — rosemary-forward with a clean, earthy finish. What it feels like: A rich, creamy lather that rinses clean. No residue, no waxy buildup. Hair dries with noticeably more body and lift at the roots after the first wash. Switching from liquid shampoo? Give your hair 2–3 washes to adjust. Most people see the best results after the first week. Sulfate-free · Paraben-free · No synthetic fragrance · Phthalate-free · pH-balanced · Vegan · Cruelty-free · Plastic-free.

Sodium Cocoyl Isethionate — derived from coconut fatty acids; a mild, sulfate-free surfactant that produces a creamy lather without the scalp-stripping harshness of sodium lauryl sulfate. (EWG: 1)
Behentrimonium Methosulfate — plant-derived from rapeseed oil; a gentle conditioning agent that detangles without leaving the heavy silicone-like coating that weighs fine hair down. (EWG: 1)
Longsheng Rice Water — fermented rice water sourced from Longsheng, China, where the Red Yao women have used it as a primary hair care treatment for generations; rich in amino acids, inositol, and antioxidants that support strand integrity.
Cocoa Butter — cold-pressed from cacao seeds; provides slip and bar texture without depositing heavy residue on fine strands. (EWG: 1)
Sodium Lactate — derived from the natural fermentation of sugars; a humectant that helps the bar hold its shape and supports the scalp's natural moisture balance. (EWG: 1)
Glycerin — plant-derived; draws moisture to the hair shaft and scalp surface, keeping the scalp reset rather than tight or stripped after washing. (EWG: 1)
Jojoba Oil — cold-pressed from the jojoba shrub seed; its molecular structure closely resembles the scalp's own sebum, making it a notably lightweight botanical oil that is less likely to coat or flatten fine hair. (EWG: 1)
Cetyl Alcohol — plant-derived fatty alcohol from coconut or palm; used as an emollient and bar stabilizer, not a drying alcohol — it contributes to the smooth, creamy lather texture. (EWG: 1)
Shea Butter — cold-pressed from the shea tree nut; used in a supporting role here for bar consistency and scalp comfort, not as a heavy coating agent. (EWG: 1)
Butylene Glycol (Plant-Based) — plant-sourced humectant and texture enhancer; helps actives distribute evenly through the lather. (EWG: 1)
Stearic Acid — plant-derived fatty acid; gives the bar its firm, long-lasting structure and contributes to lather density. (EWG: 1)
Hydrolyzed Rice Protein — rice protein broken into smaller peptide chains; the reduced molecular weight allows it to absorb along the hair shaft, supporting strength and resilience in strands that have become fragile or prone to breakage. (EWG: 1)
Broccoli Seed Oil — cold-pressed from broccoli seeds; a lightweight, silicone-alternative oil that adds shine and smoothness to the cuticle without the buildup that silicone leaves behind. (EWG: 1)
Bamboo Extract — derived from bamboo stems; a natural source of silica, which supports hair shaft structure and contributes to a fuller, more resilient feel at the strand level.
Rice Bran Oil — pressed from the outer bran layer of rice; rich in vitamin E and ferulic acid, it supports scalp health and helps protect strands from environmental stress. (EWG: 1)
Vitamin B8 (Inositol) — a naturally occurring compound found in rice water; supports the structural integrity of the hair follicle and is one of the key components researchers associate with rice water's conditioning properties.
Vitamin B5 (Panthenol) — a provitamin that penetrates the hair shaft and binds moisture; helps fine hair feel thicker and more resilient without adding weight. (EWG: 1)
Rosemary Leaf Oil — steam-distilled from rosemary herb; traditionally associated with scalp circulation and used to support a healthy scalp environment — the herbal, slightly sharp scent is real rosemary, not a synthetic approximation. (EWG: 1)
Biotin — a B-vitamin (B7) that supports keratin infrastructure, the protein your hair is built from; included here as part of the strengthening and scalp-supporting complex alongside rosemary and rice water, rather than as a standalone growth claim. (EWG: 1)
Lavender Flower Oil — steam-distilled from lavender blossoms; contributes a soft floral note to the herbal scent profile and has a long history of use in scalp-comfort formulations. (EWG: 1)
Vitamin E (Tocopherol) — plant-derived antioxidant; helps protect the scalp and strand from oxidative stress, which can contribute to dullness and brittleness in fine hair. (EWG: 1)
Marjoram Leaf Oil — steam-distilled from marjoram herb; a close botanical relative of rosemary that adds depth to the herbal scent and has traditionally been used to support scalp comfort.
Roman Chamomile Flower Oil — steam-distilled from chamomile flowers; gentle and calming on the scalp, with a soft, clean floral note that rounds out the herbal profile. (EWG: 1)
Peppermint Leaf Oil — steam-distilled from peppermint leaves; wakes up the scalp the way cold water wakes up a face — the cooling sensation is immediate and grounding, a signal that something real is happening at the root. (EWG: 1)
Lemongrass Leaf Oil — steam-distilled from lemongrass; adds a bright, clean green note to the scent and has traditionally been used to support scalp balance. (EWG: 1)
Aloe Vera — cold-processed from aloe leaf gel; a lightweight hydrator that soothes the scalp without coating the strand — one of the few botanicals that gives fine hair moisture without weight. (EWG: 1)
Plai Root Oil — steam-distilled from the plai root, a Thai ginger relative; used for its scalp-soothing properties and its clean, slightly spicy herbal character.
Kunzea Oil — steam-distilled from the kunzea plant native to Tasmania; supports scalp comfort and adds a subtle eucalyptus-adjacent freshness to the overall scent.
Helichrysum Flower Oil — steam-distilled from the helichrysum (immortelle) flower; known for its antioxidant properties and used to support scalp skin health and resilience.

1. Wet your hair thoroughly with warm water — fine hair activates the lather best when fully saturated before the bar touches it.
2. Hold the bar in your palm and rub it between your hands for several seconds, or glide it directly along the crown and roots two to three times. The lather builds slowly — let it.
3. Work the lather into your scalp with your fingertips using small circular motions, focusing on the root zone and any areas where you notice flatness or thinning. Spend at least 60 seconds here.
4. Let the lather travel down the length of your hair as you rinse — this is enough conditioning for fine, straight hair; avoid piling hair on top of your head, which can create tangles.
5. Rinse thoroughly with cool or lukewarm water until the water runs completely clear. A full rinse is what keeps fine hair from feeling heavy or coated after the bar.
6. If you are switching from a silicone-heavy liquid shampoo, allow 2–3 washes for your scalp to recalibrate — any initial adjustment is your hair clearing prior buildup, not the bar causing residue.
