Gray that stays soft, not wiry rice water amino acids smooth the coarser texture gray hair picks up

Description
Purple toning shampoo bar for brassy blonde, gray and silver hair — tones without drying.
Who it's for: Blonde, highlighted, gray, silver, white and salt-and-pepper hair that turns yellow or brassy between washes. Works on fine, thick, straight, wavy and curly hair, and on beards going gray.
What it does: Neutralizes yellow and orange undertones so blonde reads cooler and gray reads brighter and whiter — while biotin and Longsheng rice water leave hair soft instead of stripped.
How it works: Natural purple pigment from sweet potato powder cancels warm tones on the color wheel. Fermented rice water delivers inositol and amino acids into the hair fiber. Biotin supports keratin so color-treated and aging hair stays strong and flexible. No sulfates, so the cuticle isn't blasted open to deposit color — the reason most purple shampoos leave hair like straw.
What it feels like: Rich lather with a light purple tint. Rinses clean, no residue. Hair feels cool-toned and soft right away; brassiness is visibly reduced after the first wash and keeps improving over the first few weeks.
Scent: Calming lavender — soft and spa-like, not sweet, not herbal. Doesn't linger.
How to use: 1–2 times per week for maintenance. For heavy brassiness, use 3 times the first week, then drop to once weekly. Pair with the Purple Conditioner Bar to seal in moisture.
Sulfate-free · Paraben-free · Phthalate-free · pH-balanced · Vegan · Cruelty-free · Plastic-free · 100+ washes per bar. Purple pigment from sweet potato powder, not synthetic dye.

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.
6. Follow with a moisturizing conditioner bar on mid-lengths and ends.

My hair started turning white when I was 12 years old (genetics) so I do dye my hair. This is the best product for me because my hair is thick, my scalp is naturally dry not oily. My hair has continued to grow and stay healthy thanks to Viori products. Whenever I get compliments, I tell people get Viori it’s for everyone! :)
I have wavy, curly salt pepper hair and this is the only shampoo I use, (purple toning shampoo) my hair looks and feels great!
At 68 years old I get nice compliments on how I have beautiful hair.
Thank you Viori !
Christine ☮️☮️
I cut my hair in May 2026 and been dying the bottom part (peekaboo), but I’ve done some damage with bleaching and coloring but the volume has been doing wonders with my shampoo bar
I’m subscribed that’s how much I love Viori my hair has grown so much before I started using Viori shampoo bars and conditioner my hair went from above my shoulders to above my waist I’ve been using the bars for 2 years now almost 3 I think and I’ve have been trimming as well so this really helped me when nothing could grow my hair out Viori did!!!! Thank you again.
I used to get dry dandruff and dry scalp on the edge of my scalp not anymore ever since I started using the shampoo my scalp and my hair is so so healthy 10 out of 10 I definitely recommend oh and not the simple fact that it smells orgasmic.🙃🥰😍😉😉
You can't even imagine how amazing this dry shampoo smells! ❤️ I washed my hair with it today, and I'm shocked at how good it is! A huge thank you to everyone who created this product!
I needed to wait till I could use this to leave a review, so far I LOVE IT! I have long thick hair that I haven't taken care of I work in a kitchen so my hair is always tied up or in a braid, lots of breakage and overall damage. Since I've been using this bar I can run my fingers through my hair and it not tangle. And I've noticed that my scalp and hair doesn't get as greasy after a few days like it used to. My hair feels clean and moisturized. So far they got me as a customer :) coconut bliss is the one I got
I live in Louisiana with SO much humidity and the only way to fight the sweaty hair is by drying out your hair with harsh shampoo. I never thought I could have Cali hair in the south but, the past few weeks, everyone keeps commenting on how shiny and healthy my hair looks! I can’t get enough of this bar!
I love the shampoo bar doesn't take up much room, I can buy several and store them easily. Using in the shower is very easy , get it wet and scrub through my hair. It leaves my hair feeling clean. It's not heavy, meaning my hair doesn't feel like it has product or residue left. I just wish it lasted a little longer. Great product overall, I will be purchasing more and want to give the conditioner a try.!!
Makes my hair thicker, soft and my scalp feels noticeably better. Very impressive. The purple toner bar works good to remove any yellow hue from my grey/white hair.
What can I say other than I’m floored! I’ve washed and conditioned my hair twice with the shampoo and conditioner for blonde/silver hair. My hair is super soft (it’s usually coarse) and the color is bright and shiny with minimal frizz!! Really happy with my purchase. I highly recommend to my silver sisters.
I have had issues with my hair my whole life. Dry hair. Hair loss. Slow growing. I kept chasing new products. Thyroid. Suppliments. So many Drs. Then I developed rashes on my scalp and opted to try Viore. The right Viore bars transformed my hair. Then like a dummy I went back to a high end line and my hair started getting dry tangly and itchy scalp again.
So I’m back w Viore for good. And maybe that’s what everyone will get for holiday presents this year.
I love this shampoo! I've been using it for at least a year and it never fails to brighten my hair without sacrificing the weightlessness and softness I desire. It also adds a shine that I simply adore! Viori is second-to-none when it comes to this and I would recommend this to any blonde wanting to tone their brassy tresses without having to worry about damage or dryness! I would recommend all Viori products, for that matter!
Most purple shampoos fix the tone by drying you out
Blonde, gray and silver hair is already more porous than pigmented hair. Most toning shampoos use sulfates to blast the cuticle open and deposit pigment — which is exactly how the hair ends up brittle, wiry, and dull a week later.
0 1
Purple shampoo that leaves hair like straw
Sulfates strip the natural oils that keep porous blonde and gray hair flexible. You get a cooler tone for a day and rougher, drier hair for the rest of the week.
0 2
Brass and yellow that keep coming back
Without a moisture barrier to protect the tone, warm and yellow undertones resurface fast — from hard water, sun, heat tools, or just time between washes.
0 3
Gray that turns wiry, dull, or dingy
Gray and white hair has less natural oil and a coarser texture. Strip it and it goes frizzy and dull. Skip toning and it goes yellow. Most products make you choose.
THE ANSWER
A toning bar that adds moisture back while it tones.
The Purple Toning Shampoo Bar neutralizes brass and yellow on blonde, gray and silver hair — without the sulfate dryness that comes with almost every other purple shampoo.
Longsheng rice water delivers amino acids and inositol into the hair fiber while natural sweet-potato pigment works on the surface to cancel warm tones. Biotin reinforces keratin so color-treated and aging hair stays strong and flexible. The result is blonde that reads cooler, gray that reads whiter and brighter, and hair that feels softer after the wash than it did before it.
Why it works on brassy blonde, gray and silver hair
Longsheng rice water is rich in inositol — a carbohydrate that penetrates the hair shaft and repairs damage from the inside — while cool-toning pigment neutralizes warm tones on the surface. Together they tone and strengthen in the same wash, which is why customers report softer, brighter hair rather than the dryness they expect from a purple shampoo.
Fermented rice water repairs the hair fiber
Inositol and amino acids from Longsheng rice water penetrate the shaft and reinforce it from the inside — the same rice water the Red Yao women use as their primary hair treatment.
Cool-toning pigment neutralizes brass without sulfates
Purple sits opposite yellow on the color wheel. Natural pigment from sweet potato powder cancels yellow and orange undertones on blonde and gray hair without opening the cuticle to do it.
Biotin supports thicker, fuller-looking hair
Biotin is a B-vitamin that supports keratin production — the structural protein in hair. Aging and color-treated hair both lose keratin integrity, which is where thinning and brittleness start.
Sulfate-free cleansing preserves moisture in porous hair
Blonde, bleached and gray hair is highly porous — it absorbs and loses moisture faster than untreated hair. Sulfate-free cleansing leaves the lipid layer intact so the hair holds onto moisture between washes.
From the rice terraces of Longsheng to your shower — the most powerful, clean haircare you have ever used.

FAQ
GOOD TO KNOW BEFORE YOU BUY.
Both. Gray, silver and white hair yellows the same way blonde goes brassy — warm undertones building up from water, sun and product. The purple pigment cancels those tones on any light hair. Most of our reviews on this bar are from customers with gray, silver or salt-and-pepper hair.
No. That dryness comes from sulfates, which most purple shampoos use to open the cuticle and deposit pigment. This bar is sulfate-free and built on rice water and biotin. Customers with dry, gray, bleached and fine hair consistently report hair feels softer after this bar than before it.
Most customers see brassiness visibly reduced after the first wash, with the biggest change over the first 2–3 weeks of regular use. For very yellow or very brassy hair, use it three times the first week, then once weekly to maintain.
No. The pigment is natural sweet potato powder, not synthetic dye. It lathers with a light purple tint and rinses clean.
You can, but you don't need to. 1–2 times per week keeps tone in check for most people. Alternate with your regular Viori bar on other wash days. Using it more often won't turn hair purple — the pigment is too gentle for that.
The shampoo bar cleanses and tones. The Purple Conditioner Bar seals the moisture in and continues the toning between washes. On gray and bleached hair, which is naturally drier, the Duo is what customers rate highest.
Usually 2–3 washes. Your hair is adjusting from sulfates and silicones to a gentler cleanser, and it can feel different the first week. Rinse thoroughly and it settles.
Each bar lasts 100+ washes for most people — the equivalent of 2–3 bottles of liquid shampoo. Keep it dry between uses (a bamboo holder helps) and it lasts longest.
