Absolutely LOVE this shampoo and conditioner. Why? Leaves my hair clean, moisturized and frizz free, plus it helps build strong and healthy hair. This pic show hair air dried with zero styling product on it, speaks for itself!!
My hair has never been healthier and silkier!! I appreciate your business so much!!
This product offers a complete experience from the moment you receive it. The beautiful jewel box that holds the shampoo bar feels like a special surprise. Its soft, pleasant scent and the quality of the product stand out right away. I am very happy with the results and highly recommend this shampoo. The customer service is excellent as well.
I love the biotin shampoo bar!!! I tried SO many different shampoos for dandruff and oily hair. This is the only one that has worked. I tried custom made shampoos, I tried head shoulders, I tried rotating with various products. Only this bar has worked!! It takes a bit to get used to using a bar, but I honestly love it and prefer it over regular shampoo now. Seriously amazing, and my hair looks great. I can't wait to try other bars ive bought. I do have a tip, the bamboo holder is great, but only fits 1 bar so if you want one for conditioner, get another one. I only have 1 bar holder and 2 bars so... it would be cool to make a holder that holds both.
I love this shampoo and conditioner. I used to use Hidden Waterfall religiously, the tried the castor oil one on a whim. It makes my hair feel so thick! If you have light/thin hair, this shampoo/conditioner will add so much thickness!
My hair feels soooo so good after switching to this for my shampoo & conditioner. I was using professional products before, since I’m a cosmetologist, but this still beats any of that! Clean ingredients make my hair happy, shiny and super soft. Will never go back!
Works wonders, my hair feels great after a shower and I can wait a few days in between washes with this one. Smells really nice..
Love it
I love the rosemary conditioner because it has made my hair look so much smoother and shinier after just 3 washes! (The before picture is with the white shirt and the after is with the black.) My hair was looking so bad I always kept it up but now I can wear it down confidently. Very happy with this product.
I have been using Viori for several years now and this bar's scent is wonderful. I'm hopeful the biotin will help with the structure of my hair over time and these bars last me well over 6 months.
My daughter and I LOVE viori shampoo and conditioner bars! (Also love the sugar scrubs!) We both have thin hair, we started using this rosemary and biotin and it makes our hair so soft and shiny! And it smells great! Highly recommend! I wont use any other shampoo or conditioner brand after using Viori! Ive been using it for a few months now and my 2 daughters and I just love it! I use a different shampoo bar from them for my youngest daughter because her hair is super thick, and it makes it so soft and easy to brush!
I absolutely love Viori! My sister was experiencing postpartum hair loss, so I gifted her this shampoo, and after just one month, we could already see a noticeable difference. It helped support healthier hair and encouraged new growth. I had the same experience after both of my pregnancies — it really helped me during my postpartum hair loss journey. I’ve been using Viori for years now, and it continues to be one of my favorite hair care products. Highly recommend!
Super cute bar formed shampoo. Smells nicely & lathers up easy. Hair is looking better and less frizz. Strengthens hair while also giving my thin fine hair looking fuller
Loving my new healthy looking hair and growth
I love this shampoo, my hair is silky and full. I us two different kinds together and then use the rince that goes with this shampoo. It's Wonderful!
Makes my hair feel so full and soft! New favorite shampoo.

I’m really glad this came out! I’ve been dealing with thinning hair and losing hair a lot and I have noticed a drastic difference. I’m very grateful for this product shampoo and particular!
Love it!! I’ve been using Viori for a couple years. I was excited when I saw the Castor Oil shampoo and conditioner. It has definitely made a difference in my hair. It’s very moisturizing. I use it in conjunction with the Rosemary and Biotin. Highly recommend.

Never going back to "regular shampoos" I had ran out for about a week till my shipment came in and immediately could feel the difference in my hair it became so brittle & dry worst week of my life forever faithful to you guys for about 2 years 😁.
I love these. Ive got very long curly hair thats been thinning. Makes my hair silky smooth and soft and ive noticed regrowth! Works well with fashion colored hair too!
absolutely love this my hair felt thicker after one use so happy thank you :)
My hair is never been this long and shiny
My hair it the softest it's ever been! I get so many compliments on how shiny and bouncy my hair looks especially after bleaching! My hair dresser even asked what Ive been using. And it's been these bars! My heat usage hasn't changed and my scalp looks and feels cleaner even in-between washes! and my hair looks so strong! I love love lovee
Rosemary & Biotin Shampoo Bar for Volumizing & Strengthening
After just the first time using viori my hair is softer then ever and no frizziness! I will definitely continue using.
I love the rosemary and biotin shampoo. This is my 2nd bar I've ordered. Ad you can see I've already used it several times. I wash my hair twice weekly and this makes my hair so clean and soft. Will definitely recommend and continue to buy their shampoo bars.
Love how shiny and soft it got my hair. I have long thick hair and decided to try the Rosemary to start to see how my hair would react. So far I love it and look forward to trying out more!
My stylist said at my age of 60 my hair is still thick and strong that’s because I’m using Viori shampoo and conditioner bars for years now. I have tried different varieties of their products. They really meant business. Good job.
Rosemary & Biotin Shampoo Bar for Volumizing & Strengthening
So happy I decided to give this a try! I was definitely skeptical because I like a good lather and like my hair feel clean and I wasn't sure this would do the trick, boy did it do the trick and more! I'll never go back to old unhealthy shampoo! This bar lathers like a dream and my hair looks so healthy and clean afterwards! I chose the rosemary and biotin bar because I've noticed more falling out lately. I can't wait to try more scents but I can tell this is going to last a long time. My plan is to buy more and just alternate cause I'm impatient. Lol. My favorite part is that it's all natural, no more chemicals for me or my family!
Rosemary & Biotin Shampoo Bar for Volumizing & Strengthening
Since starting this shampoo and conditioner I have 100% been happier with my hair. I should have switched sooner. For me I love it because my scalp feels better longer and my oil doesn't come as fast to my hair. Im not claiming it helps with thickness or growth but I'm saying if you are looking for good products I say go for this! I just wish the conditioner bar lasted me longer. It somehow does not last like the shampoo bar. That's the one downfall I have. Also I don't track my buys but I'd say I need an order every 6 weeks. My hair is to long to last longer.

Rosemary & Biotin Shampoo Bar for Volumizing & Strengthening
I bought this with the coconut bliss shampoo bar, and the combo is great for what I need it for. I have a lot of damage to my hair from working in restaurants and I feel like I'm actually doing something. I used to use severe damage conditioner and shampoo from the store and It just never seemed to actually moisturize my hair after ward. This conditioner is finally giving my thirsty hair a drink thank youuu. :)

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.
