Description
A purple toning shampoo bar with biotin and rice water for blonde and gray hair. Brass creeps into blonde and gray hair fast. This purple shampoo bar neutralizes yellow and orange undertones while strengthening hair with biotin and Longsheng rice water. The purple pigment comes from sweet potato powder — not synthetic dye — so it tones without staining or drying. Made with the same fermented rice water the Red Yao women of southern China are known for using as their primary hair treatment. Biotin reinforces keratin to keep color-treated or aging hair strong and flexible. Most purple shampoos strip moisture — this one adds it back. Scent: Calming lavender.

3. Work the lather through roots and mid-lengths, then smooth down to ends.
4. Leave on for 1–3 minutes to allow the toning pigment to neutralize brassiness.
5. Rinse completely with cool water to seal the cuticle and lock in shine.

Before and after — bleached, dry, damaged hair

"I've gotten so many compliments since switching to Viori. I've never loved my silver hair this much before. It's soft, shiny, and really complements my eyes. I finally feel confident wearing my natural silver."
"Salt and pepper, mostly salt. The yellow is gone and the silver actually shines in the light."
VERIFIED REVIEWS
What bleached, dry-haired customers are saying
From people with dry, damaged, or color-treated hair.
THE PROBLEM
Fixing the tone keeps making the dryness worse
Bleached hair is already compromised. Most purple shampoos treat brassiness by stripping — and stripping bleached hair is the last thing it needs.
Purple shampoos that dry out your hair
Most toning shampoos rely on sulfates to open the cuticle and deposit pigment. On bleached hair that is already porous and fragile, sulfates strip what little moisture is left — leaving ends more brittle after every wash.
Bottled purple shampoo trades moisture for tone.
Most purple shampoos tone with synthetic dye in a sulfate base. The yellow goes — and so does the moisture. Gray hair is already drier and coarser, so the fix is what leaves it feeling like wire. Some stain hands and showers, too.
Thinning that gets harder to ignore
Bleached hair that is repeatedly stripped and dried out breaks off before it can grow. Over time, the overall density drops — not because the follicle is failing, but because the existing strands are too fragile to survive a full wash cycle.
THE ANSWER
Tone and moisture in the same bar
The Purple Toning Shampoo Bar neutralizes brassiness and supports thicker, stronger hair — without the sulfate dryness that usually comes with a purple shampoo.
Purple neutralizes yellow — that's color-wheel arithmetic, and it's why purple shampoo exists. The difference is what carries the purple. Most bottled purple shampoos pair synthetic dye with a sulfate base — the tone comes at the cost of moisture, and sometimes with purple hands. This bar tones with sweet potato pigment in a base of rice water, cocoa butter, and shea — the yellow lifts while moisture goes back in. Hair dries cooler in tone, softer, and brighter. And honestly: toning is maintenance, not a one-time fix. New gray grows in, water keeps depositing minerals, sun keeps doing what sun does. That's the argument for a bar that tones every wash without drying — you can use it as your everyday shampoo, not a once-a-week corrective.

Backed by the science
Why it works on bleached, brassy hair
The science behind toning, repairing, and strengthening compromised hair — without sulfates.
-
Fermented rice water repairs the hair fiber
Longsheng rice water is rich in inositol, a carbohydrate that penetrates the hair shaft and repairs damage from the inside. Amino acids from the fermentation process strengthen weakened, porous bleached hair with every wash.
International Journal of Cosmetic Science — rice water and hair strength -
Cool-toning pigment neutralizes brassiness without sulfates
Purple pigment works on the color wheel to cancel out yellow and warm tones deposited by oxidation. Delivering that pigment in a sulfate-free base means the tone is corrected without further stripping the cuticle.
Color theory and toning pigment in hair care -
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.

FAQ
GOOD TO KNOW BEFORE YOU BUY.
No. The pigment is sweet potato powder, not dye — reviewers with all-over white hair report "no purple hue... very natural look." It won't stain your hands or shower either.
Yes. It tones the silver strands and leaves pigmented hair alone; reviewers with salt-and-pepper hair report the silver brightening without the dark hair changing.
That's one of the most common things reviewers mention — mineral deposits are a main reason gray turns yellow, and toning plus a clean rinse addresses the tint. If your water is very hard, a periodic clarifying wash helps too.
Yes — the label says "Blonde & Gray": it's the same bar sold to blondes fighting brass. Sulfate-free and gentle on color.
As your regular shampoo, 2–3× a week. It tones gently each wash rather than depositing heavily once a week, so there's no over-toning cycle to manage.
100+ washes — about the same as a 30oz bottle. Washing 2–3× a week, that's several months. Keep it dry between uses.
Yes — vegan, cruelty-free, no sulfates, parabens, phthalates, or synthetic dye.
Calming lavender, from lavender essential oil. Reviewers mention the scent often — it's noticeable in the shower, subtle after.
The scent comes from lavender essential oil, plant-based rather than synthetic fragrance. If you prefer no scent at all, our Native Essence bars are fragrance-free. As with any new product, patch-test if you're reactive, and check the full ingredient list above.
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.
