So happy with using Viori Shampoo bar and Conditioner bars. They have made my hair feel very healthy and smooth! I had some thinning a few years ago after a stressful time. Viori helped repair this.
My hair is soft and shiny since I have been using your product. When drying, it falls right into place due to using Viori shampoo soap . It is also so easy to pack when am travelling….no more bottles that take so much room in my luggage. Viori shampoo soap has been a wonderful discovery and I am just so happy with this product especially that my hair texture is coarse, dry and difficult to manage.
I've been using Viori for awhile now- and it's fantastic every time. Sometimes I switch to an older shampoo for convenience, and every time I do, the difference is so obvious! I love my Viori. I don't think my hair has ever been happier!
I’ve been using Viori products for around 5 years, and I’ve loved them from the very beginning. The quality is amazing, and my hair truly enjoys them. I’ve tried almost all of their shampoo bars, and I love every single one.
I love this shampoo! I have used a few different brands of bar shampoo, and a few different scents from this brand. This is by far my favorite. Since I started using it, my hair has more volume, fewer knots, and it has grown so much. I definitely recommend
First time using the shampoo soap. Hair feels great. Wouls definitely recommend.
Really surprised by how effective this shampoo bar and conditioner is cleaning my hair and making it super soft and shiny
The first photo is before and the 2nd is after. My hair is so much fuller and my stylist says I have so much more hair growth! I love the product!
Don’t mind my snake pet 😁, but my hair is soft and grew faster than it usually does!! I’m a cosmetologist & barber and would love to sell your products to my clients! I’ve even gifted to family members. It’s way better than the bottled products the industry uses. Get it! You won’t regret it!
My hair is thicker, longer, and healthier than when I was 30! I'll be without it!
My hair has never felt cleaner or softer, I also get so many compliments on how great it smells; best part is my hairdresser (of 15yrs) cannot believe that I still have such thick long hair for it 53+-year-old woman. She swears that all my peers have to pay good money and extensions for the same results! So thank you ♥
Hands down the best natural shampoo I’ve tried! Probably the best shampoo I’ve ever tried, natural or not! I got my hair curled on a cruise recently, and the hairdresser couldn’t believe I hadn’t had some sort of protein treatment because if how silky and shiny my hair was
I love the smell and the results are spectacular. Definitely buying again and I recommend it to everyone.
Love this shampoo bar. My hair feels so soft and silky and the smell is wonderful! (Hidden Waterfall)
I have enjoyed the shampoo bars for 5 years now. This a first for me ,with any shampoo products I would use for a few months than i would notice my hair was dull and flat .. thank you
Love everything about it from the smell do how your hair feels afterwards!
My hair definitely is looking more healthier!
I got the waterfall shampoo and I am loving it so far. My mother uses the biotin one and looking forward to great results. Thank you !
During college I lost a lot of hair due to stress. I tried these shampoo bars and they really helped. It got longer a thicker. I think most impressive is the fact that I bought them in July and I am just now (late dec) needing to replace the shampoo bar. The conditioner is still going. Absolutely recommend. Scent is not chemically or too strong. 10/10!
This shampoo has made my hair soft and very shiny. Love it!
I’m pissed off that I didn’t get this sooner. 😂 I had been wanting to get this for a while and finally got the conditioner bar. I noticed a difference of softness in my hair the first and second day after using it. I decided to get the shampoo bar too. I have only used that one once so far and love the scent. I am looking forward to seeing how that one does after using it for a month or two. Altogether very happy with the quality of ingredients and the foam level of the shampoo bar.
I think my hair has been growing in thicker since I started using Viori products. I like the way my hair feels during and after washing. Love the price and how healthy it is. So grateful I found this company.
I really like this product, my hair shines, it feels healthy and it smells so good!
Love absolutely love this product
Absolutely amazing! Strengthens my hair to make it thick and very shiny, i also use a leave in conditioner to further moisturize my hair :D
I typically don’t really hype up hair products that much but this shampoo bar has actually made a huge difference on my hair. It lathers up really well too which makes it a lot easier for me to really wash my whole head. My hair is really soft and feels clean up to a couple days so I wash my hair less frequently as I used to as well.
I have enjoyed regrowth and body since I started use this shampoo
Been using viori for over a year and my hair is light shiny and growing fast
I've been trying to grow my hair out forever! I had finally gotten it to start growing then it seemed to stop growing. I couldn't get it to grow past my bra strap or the bottom of my shoulder blade area. I got Viori to see if it could help. I had been seeing it so often on my social media. My opinion? It's fantastic!! I finally got it to start growing again. It's getting longer, stronger, thicker. I already have thick hair! Its shiny and soft and only after a couple months of using it. I love this stuff!!
My hair is shining like never before ❤️
The first use I was so amazed. I feel so squeeky clean and the conditioner is way too different from the normal conditioner I used before. My hair looks so healthy plus it smells so nice even after a day. And the good thing is Ive been using it for a couple of weeks and day by day my hair fall is getting less. I wanna try the other scents❤️
both my mother and I fell in love with these hair bars!
Its amazing , hair is so light and tangle free!
My hair is damaged from many years of different processes, I have tried many products to help it with not much success. I was hesitant to use a soap bar as shampoo and conditioner but I wanted to give it a try and... is working fantastic! My hair feels better than before, softer, stronger and healthier. I know is going to take time to restore it but at least now I have hopes to finally have a healthy hair.
I was hooked by the story on Instagram as to how you got started I’ve been wanting to use a product that is safer in my hair as I’m getting older. It was so amazing to wash my hair last night and it smelt so good. I love the packaging that came with the conditioner. Very cool!! I’m going to be sending all my daughters set for Christmas!!
my hair has been feeling a lot more healthy!
I’ve never tried a shampoo bar before but was pleasantly surprised with this! It got my hair clean - like I literally heard it squeak - but didn’t make it dry. I have really fine hair and when I blow it out it’s always fuzzy and super lightweight. This makes it smoother and really cuts down the fuzz. It gives it some weight without being greasy or drying. It looks so much better. I absolutely love it!!
I was very impressed with the packaging and the design of the bar itself. The bar lathered nicely with some water. When I blowed dried my hair with big round bush my hair was very manageable and smooth to easily round the brush. Once my hair was styled, it had a nice bounce and laid nicely.
I was skeptical about how I would feel about using a shampoo bar (as opposed to liquid shampoo that I’m used to), but I am so surprised by how much I like this Viori bar! It lathers soooo well! And I feel like it really is helping my hair. I didn’t take any before pics unfortunately, but I definitely feel like my hair is thicker(?) or at least there’s less fall outs when I shower. Very happy with this and I intend to repurchase! :)
I just started using it, so I'm not sure about hair growth yet, but I normally have oily hair so don't use much, if any, conditioner. But the shampoo and conditioner bars are amazing! No oily hair anymore and I love the smell!!!

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

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.

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.
