One bar is the equivalent to one 30oz bottle of liquid shampoo.

After cancer treatments my hair felt like straw and now it feels silky.
Since using VIORI, I have noticed a huge change in my hair growth, a healthier scalp, and overall feeling and texture of my hair. I love this product. I wish I found it sooner and have recommended it so many times..
It's helping with my hair loss and love the way it makes my hair look and feel.
My hair is strengthened and has a fuller texture than ever before. I use the Castor Oil shampoo together with this one once a week. It makes such a big difference. I'm so glad you are here... 💖
This marks my 5th year using Viori. I have never found a product like this ,that consistently keeps my hair healthy and shiny.. thank you
I love the Viori shampoo bars, conditioner bars and the body bars. I have tried several just because I love the scents and all leave my hair soft, shiny, healthy looking and easy to manage/style. I have very long fine hair and these products are amazing. I have been using Viori products for a few years now and will never go back to other bottle brands. These bars last me a while.
Beautifully wrapped. Immediately the fresh clean fragrance fills the air. I have volume!
After the 1st week of using this stuff, even after day 1 I noticed a difference!! My hair was softer, silky and not so crazy or dry. I definitely recommend again and make it my main shampoo care now! Thank you so much!!
I have used Viori products since 2023. My goal was always to reduce plastic shampoos and conditioner’s, while finding a product that would help my hair grow. Off and on over the years I would switch other products but non never made my hair feel as good as viori. when I was consistently using viori my hair felt so clean and less oily. Not only is the product environmentally but it is also contributing to the women who hand craft this Amazing product. I am no longer switching back to plastic shampoos or conditioner’s things my go to for hair care.
Felt like it actually cleaned my hair without drying it out!!!! Depending on how long it lasts and the price point this may become a normal part of my shower routine instead of store bought chemicalized products ((idk if that's a word but it is now lmao)) smell incredibly good as well!!! Very tempted to get the conditioner version just to have the smell after shower haha
I had purchased the Essential Oil/Citrus Zest Duo quite awhile ago for the girls in my family and kept a set for myself but hadn't tried it. I really like it alot. My hair is long and naturally curly. I took this duo with me to the salon and my stylist washed and conditioned my hair with them. She loved the smell and how silky it left my hair. She wanted to blow dry my hair straight and she couldn't believe that I didn't have color highlights in my hair. It's been 23 years since I had any color highlights put in my hair. Just lovely natural tones of grey/blonde/platinum. I love all of the products I have bought and used from Viori. Thank you. Jane in Vancouver BC Canada ❤️
Feels clean and suds just enough to give me what I like ! I feel my frizz has lessened too
Love the shine and volume Viori shampoo and conditioner give my French pixie hairc- It’s great for my 57 year old natural hair and this pic with no styling products freshly out of the shower blow dry nothing but Viori shows the amazing shine!
I'm taking my long hair on a Vacation because Viori gave me back my confidence to stop hiding my hair under a baseball cap. It's time to let this lioness roar.... 🦁 👑 ❤️
Viori is beautifully made and smells so nice!!! This has been such an experience with the bars and I have to say the changes and growth in my hair in just a few months has been phenomenal!!! My hair has grown Three inches in four months in using these beautiful shampoo and conditioner bars from VIORI !!!!!!
I love Viori and I recommend it to everyone who asks what I use! I have wavy, dyed, dry hair and viori has helped me repair it and bring back that moisture and shine! Will use this stuff forever :)
I've ordered several different products in the past, a few smaller +like trial sizes, which I absolutely love for travel and gift giving) shampoo soaps with conditioner and all of them were absolutely great. This one I enjoy so much, because I have white hair, which sometimes needs a little umph and this shampoo bar does it; I also enjoy that it's super easy to wash your hair and get great results. An additional benefit is that there are no plastic bottles nor pumps, but the shampoo bar and conditioner bar are beautifully packaged - great for gift giving!
I have tried a variety of different shampoo and conditioner bars and this is THE ONE! I am VERY scent-sensitive, and this citrus zest is lovely, not too much. The feel of the product is clean and my hair feels good!
I have been using Viori products for a few years now. What I love: Packaging & design Shampoo bar design - looks like a cut gem! Subtle fragrance Lathers well Hair feels clean & light afterwards Each bar lasts countless shampooing Sustainable, no plastics disposal Environmental, natural ingredients
I have been using viori soap shampoo for two years now. And I can say that my hair is in very good care and it had tremendously reduce hair loss. I would say by 80%. I have a subscription and I don't plan of canceling for as long as they are in business. The scents are all lovely as I change my order every now and then:)
Smells soooo good. Leaves my hair squeaky clean, soft and full of volume
Love love love this shampoo bar!!! My hair looks and feels much thicker and healthier! Thanks so much!!
Love it. So easy and convenient to take when traveling. Does a great job washing my hair
I’ve been using this shampoo bar for a week now, and my hair has already started to look shinier again. I have a sensitive scalp, so it’s usually hard for me to find shampoos that work well without causing irritation. So far, this one has been amazing. It hasn’t caused any reaction on my scalp, my hair looks healthier and more radiant, and it feels very soft. My hair also gets oily very easily, so I use it daily, and it still doesn’t dry my hair out.
Wonderful smell and rinses clean leaving my hair feel smooth and soft.
It took a bit of time, but I’ve been using it for two months now. I notice I have less hair falling out and the actual strand seems thicker. My hair is usually incredibly thin, so this now makes my hair seem more normal. Hoping it continues to improve the growth of more strands 🤞🤞
Smells delicious and I feel confident using it. Viori shampoo bars are great to add to your daily self care self love routine.
This makes my hair so full of life and easy to style!
The bar shampoos are amazing. I have colored treated hair and my color last longer and i have seen an improvement in length. I was skeptical at first but i love this product.
I absolutely love it. I’ve tried a few different bar shampoos and they were just ok, but now that I’ve found a professional grade product I’m really enjoying it. Can’t wait to try the conditioner next! Are they pthalate free?
Smells really good and as always hair feels amazing
The best bar shampoo I have found. I have fine hair but a lot of it. Most shampoos either dry it out or make it so that I have to use conditioner or a ton of styling product. This shampoo bar is so great that I only need one product… the bar itself. Highly recommend!
Conditioner bar made a huge difference on my dry ends, leaving them silky and smelling great💕
Love it! It takes some time to get it to lather, but don’t give up! It leaves my hair looking and feeling great.
I LOVE this product!! I have long, straight hair. I’m quite picky about the type of products I put on my body. And I HATE plastic waste, + I’m sensitive to scents in products. I was tired of traveling with liquid shampoo and conditioner, OR relying on the hotel/Airbnb to have a product I like. Traveling with small bars of shampoo and conditioner is a game changer. The scents are so wonderful, and there is no plastic waste! WIN WIN WIN!
I recently tried the Citrus Yao Shampoo Bar by Viori, and I’ve honestly been impressed. First of all, the scent is beautiful — light, fresh, and citrusy without being overpowering. It feels clean and uplifting, but not artificial or heavy. I’m pretty sensitive to strong fragrances, and this one feels gentle and natural. The bar lathers really well, which surprised me. It doesn’t take much product to get a rich foam, and my hair feels clean without that stripped, squeaky feeling. After rinsing, my hair feels soft and smooth, not dry or tangled. I also appreciate that Viori uses Longsheng rice water and focuses on more natural ingredients. It feels good knowing I’m using something more mindful and less chemically harsh on my hair and scalp. The bar itself lasts a long time, which makes it feel worth the price. Plus, I love the eco-friendly packaging — less plastic always feels like a win. Overall, the Citrus bar leaves my hair feeling clean, light, and healthy with a fresh scent that isn’t overwhelming. I’d definitely purchase it again.
Absolutely love how it makes my hair feel after a wash .
The Citrus Zest scent is incredibly refreshing, and the lather is richer than I expected for a solid bar. After just one wash, my hair felt weightless, bouncy, and had a natural lift at the roots that lasted all day. It cuts through oil perfectly without stripping my scalp. Plus, I love that I’m finally getting rid of plastic bottles in my shower. Will definitely be purchasing again!
smells good, crumbles easily after few washes
I love that Viori now carries their wonderful products with essential oils. As always top notch quality and my hair feels so soft. The scent is very light which I appreciate since I’m sensitive to fragrances.

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.

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.
