Best Rice Water Shampoo Bars
Quick answer
The ingredient lists reviewed name rice protein, not rice water. Kitsch's Rice Water Protein bar ($16) lists Hydrolyzed Rice Protein and states up to 100 washes. HiBAR's Moisturize ($14.95) also lists Hydrolyzed Rice Protein; HiBAR Volumize and Curl cite rice amino acids or rice protein. Kitsch is the only brand here with a rice-named bar and a wash ceiling; HiBAR is cheaper and offers a fragrance-free version.
Key takeaways
- Kitsch's rice bar lists Hydrolyzed Rice Protein as its seventh ingredient; no list reviewed names rice water itself.
- HiBAR Moisturize also lists Hydrolyzed Rice Protein; Volumize cites rice amino acids and rice protein; Curl cites rice protein.
- Kitsch states up to 100 washes ($0.16 per wash at best); HiBAR publishes no wash count.
- Rice claims are brand descriptions; no source tests rice-containing bars against others.
Rice-named bar with a wash ceiling: Rice Water Protein Shampoo Bar
Kitsch names hydrolyzed rice protein, states up to 100 washes at approx. 0.032 oz each and prices it at $16, so $0.16 per wash at best. The trade-offs: no weight, fragrance on the list, and the ingredient is rice protein rather than rice water.
Cheaper rice-protein bar: Moisturize Shampoo Bar
HiBAR lists Hydrolyzed Rice Protein, vitamin B5 and cocoa butter in a soap-free bar for dry, frizzy, damaged or color-treated hair at $14.95. The trade-offs: no wash count or weight, and bottle-equivalent claims that differ between its copy and FAQ.
Rice amino acids for fine hair: Volumize Shampoo Bar
HiBAR describes rice amino acids, rice protein and vitamin B5 for body and bounce, with a January 2024 assay cited for up to 20% more volume after one use, $14.95. The trade-offs: the assay method is not on the page, and no weight or wash count.
Rice protein for curls: Curl Shampoo Bar
HiBAR says rice protein and hydrolyzed corn starch add strength and elasticity, in a bar for curly, coily or textured hair with an unscented version, $14.95. The trade-offs: no weight or wash count, and the FAQ says only at least a 24 oz bottle.
What is a rice water shampoo bar?
A shampoo bar marketed with rice, usually in the name or description. In practice the ingredient lists reviewed show a rice-derived protein or amino acids rather than rice water.
| Bar | Name or claim | Rice ingredient on the list |
|---|---|---|
| Kitsch Rice Water Protein | Rice Water Protein bar | Hydrolyzed Rice Protein (7th) |
| HiBAR Moisturize | Rice protein smooths and detangles (HiBAR) | Hydrolyzed Rice Protein (9th) |
| HiBAR Volumize | Rice amino acids, rice protein, vitamin B5 | Named in copy; full list not reviewed |
| HiBAR Curl | Rice protein improves elasticity | Oryza Sativa extract appears on the list; rice protein named in copy |
The label tells you the marketing angle; the ingredient list tells you what is in the bar. Kitsch describes its bar as a nourishing cleanse that boosts shine in dull, dry hair.
How do the rice bars compare?

Kitsch's footnote supports an implied size: 100 washes at 0.032 oz is 3.2 oz, about 91 g. That is arithmetic from its footnote, not a published weight.
What do the brands claim about rice?
- Kitsch: a nourishing cleanse that boosts shine in dull, dry hair; free of parabens, phthalates, silicones and sulfates; pH balanced and safe for color-treated hair; vegan, cruelty-free and Leaping Bunny certified. Kitsch cites a 90-day consumer study of 40 participants using the bar and its conditioner bar together.
- HiBAR: rice protein 'smooths and detangles' (Moisturize), adds strength and elasticity (Curl) and fortifies strands with rice amino acids (Volumize). HiBAR is soap-free and lists what it omits.
These are brand claims. The studies cited involve the brand's own pairs and panels, not comparisons with a bar that has no rice.
Are there other rice bars?
Other brands reference rice in lines this guide did not review in full; Ethique, for example, sells a rice-protein bar in its range, whose page was not part of this research. Only the products above had product pages fetched. For a broader view see best shampoo bars and the brand comparison Kitsch vs HiBAR.
How does Kitsch say to use its rice bar?
Kitsch's instructions are short: wet your hair, rub the bar between your hands into a rich lather or paint it directly onto your scalp, massage with your fingertips, then rinse and repeat as desired. Its pro tip is to pair the bar with its Beauty Bar Bag, an accessory whose details are not given in the product copy reviewed. The dose behind the wash count is approx. 0.032 oz per wash, or about 0.9 g, which is a light amount; a heavy hand will shorten the 100-wash ceiling. HiBAR's rice-protein bars give no dose.
