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 Love the 𝒢𝑒𝓃𝓉𝓁𝑒 ingredients and the softness of my hair. I get a lot of compliments on the soft appearance of my hair. Thank you XOXO ;)
My hair is very thick and this product ( coconut ) has made my hair manageable and so soft
This is by far one of my favorite shampoo and conditioners I have used. It makes my hair feel so much healthier and doesn’t dry it out <3 super love
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’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.
This is the next day after my hair air dryer and I’ve done nothing else to it😊❤️
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.🙃🥰😍😉😉
I looove the smell. I love how it conditions my hair. I get compliments on my hair and the smell. I LOVE VIORI!!!
My hair is very dry from bleaching and this stuff makes my hair so soft! I’m on the right btw ha! Trying out their castor oil next
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 absolutely love viori! The shampoo and conditioner makes my hair so soft and shiny
My hair was like very dry and this stuff made it manageable and it just felt great all the way around!
Biotin Purple-Toning Shampoo Bar for Blonde & Gray Hair | Lavender Scented
My hair feels stronger and grows faster and healthier. I buy it for all my all children too.
Love will use as my regular shampoo and conditioners also
Love how moisturizing this is. Smells amazing
I love how my hair feels so soft
I love these products <3
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.!!
Something in it made my head itchy. Voluming products tend to do that
Love how my hair feels!!!

Biotin Purple-Toning Shampoo Bar for Blonde & Gray Hair | Lavender Scented
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.

My hair looks healthier and softer now
Advanced Moisturizing & Repair Conditioner Bar | Coconut Scent
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.
Purple-Toning Conditioner Bar for Blonde & Gray Hair | Lavender Scented
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!

I’m in love with Viori it gave me back my confidence my hair was destroyed it wouldn’t grow burned by bleach and hair dyes. I started using Viori and I honestly saw a difference in one month I saw new hair growth omg! I was excited I’ve been using Viori for over two years now and my hair is so long from short check length hair to now mid back long and growing! Thank you Viori you saved me.

The Science
Why a bar outperforms a bottle
-
1
Cold-press extraction
Longsheng rice is cold-pressed for inositol — the same compound trichology studies link to measurable shaft strengthening.
-
2
Sulfate-free surfactant
Coconut-derived cleanser lifts oil and product residue without stripping the cuticle. pH 5.0–5.5, scalp-matched.
-
3
Solid-state delivery
No water as filler. Every bar is concentrated active — that’s why one replaces ~3 bottles.
All-Natural Ingredients
What's actually in the bar
Longsheng Rice
HeroStrengthens
Rich in inositol — clinical work shows it reinforces the cortex of the hair shaft and reduces breakage from brushing.
Sourcing · Yao village terraces, Guangxi · single-origin
Cocoa Butter
HeroConditions
Cold-pressed seed butter. Coats the cuticle without weighing fine hair down. The reason the bar feels conditioning, not stripping.
Sourcing · Côte d'Ivoire · fair-trade cooperative
Shea Butter
HeroSmooths
Buffers the surfactant so the formula stays gentle. High in vitamin E — supports scalp barrier integrity.
Sourcing · Ghana · women-owned cooperative
Aloe Vera
SupportingSoothes scalp
Calms inflammation and itch — the active ingredient in our formula for sensitive and reactive scalps.
Sourcing · Mexico · organic certified
Colza Plant Oil
SupportingAdds shine
Light oil that closes the cuticle for visible gloss. Gone in 30 minutes — never builds up to a flat, oily look.
Sourcing · Yao region · co-cultivated with rice
Rice Bran Oil
FunctionalLocks moisture
Slips into the cuticle gaps, seals hydration in. The compound that makes the second-day finish noticeably softer.
Sourcing · Same harvest as the rice extract — zero waste

Questions
Things people ask first
How long does one bar last?
About 80 washes — roughly the equivalent of three bottles of liquid shampoo. Stored on a slatted holder, dry between uses, you'll usually get 2–3 months out of a bar.
Is it safe for color-treated hair?
Yes. The formula is sulfate-free and pH 5.0–5.5, both of which protect color longevity. Independent reporters with color-treated hair haven't seen accelerated fade.
What if my hair feels weird the first few washes?
That's the transition phase — sulfate residue and silicone buildup releasing. It usually takes 2–4 washes. If after a week it still doesn't feel right, send it back, no questions.
How do I travel with it?
Use the travel tin. Bars are solid-state, so they don't count as a liquid for TSA. One bar replaces a 12oz bottle in your carry-on.
Subscription vs. bundle — can I stack?
No — it's whichever discount is larger. Subscription gets you 20% off, the trio bundle is also 20%. We don't double-stack so the unit price stays sustainable.
What's your guarantee?
30 days. Use the bar, see how your hair feels. If it's not for you, we'll refund it — even if you've used the entire thing.
