Description
Castor oil shampoo bar for brittle, dry and breaking hair.
Who it's for: Brittle, dry, snapping hair. Color-treated and thinning hair that has gone fragile. Anyone whose ends break when they brush.
What it does: Cleans gently and rebuilds brittle strands, so hair stops breaking off mid-length.
How it works: Castor oil coats and strengthens fragile strands. Hydrolyzed rice protein bonds into weak sections. Longsheng rice water delivers amino acids into the fiber. Rose, chamomile and geranium essential oils replace synthetic fragrance.
What it feels like: Soft, cushioned lather. Hair feels pliable rather than crunchy as it dries.
Scent: Rose, chamomile and geranium — soft, floral and warm. Essential oils only.
How to use: Every wash. Pair with the Castor Oil Conditioner Bar on the ends.
Sulfate-free · Paraben-free · Phthalate-free · pH-balanced · Vegan · Cruelty-free · Plastic-free · 100+ washes per bar.

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.
Rosemary & Biotin Conditioner Bar for Volumizing & Strengthening
I love VIORIII, I put my man on we’ve both been using it for a while and love the results my hair is thicker and softer and overall more healthy
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.

keeps hair light and clean. noticed less shedding while washing than while using liquid shampoo
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. :)

Rosemary & Biotin Shampoo Bar for Volumizing & Strengthening
THE PROBLEM
Brittle hair breaks before it grows.
Hair that snaps mid-strand never gains length. You are not growing slowly — you are losing it as fast as you make it.
0 1
Dry from the wash itself
Sulfates strip the natural oils that keep a strand flexible. A dry strand is a stiff strand, and a stiff strand cracks instead of bending.
0 2
Length that stalls
Your hair seems stuck at the same place for years. It is still growing at the root — it is breaking off at the ends at the same rate.
0 3
Rough, straw-like texture
Fingers catch on the way down. Brushing pulls. Hair that should feel smooth feels like it has been left out in the sun.
THE ANSWER
Flexible hair does not break.
The Castor Oil Shampoo Bar cleans brittle, dry hair while putting back the oils that keep a strand able to bend.
A dry strand is a stiff strand, and a stiff strand cracks instead of bending. Castor oil is thick and rich in ricinoleic acid, which is why it coats and conditions where lighter oils rinse straight off. Paired with Longsheng rice water — inositol plus fermentation amino acids that reach inside the shaft — it works on both sides of the strand at once. No sulfates, so the wash itself stops being part of the problem. Hair that stops snapping mid-length finally starts holding the length it grows, which is usually what people notice before anything else.
FIND YOUR BARBacked by the science
WHY BOTANICAL ACTUALLY WORKS
Longsheng rice water is rich in inositol — a carbohydrate that supports the hair fiber from within — plus amino acids from fermentation that strengthen and smooth with every wash. The base matters as much as the actives: a coconut-derived cleanser at pH 5.0–5.5 keeps the cuticle flat, so the bar rinses clean instead of leaving the film alkaline soap bars do — and gentler cleansing means less breakage when you comb.
- Fermented rice water repairs the hair fiber
Longsheng rice water is rich in inositol, a carbohydrate that penetrates the hair shaft and repairs damage from the inside. Amino acids from the fermentation process strengthen weakened, porous bleached hair with every wash.

FAQ
GOOD TO KNOW BEFORE YOU BUY.
Yes. The title names castor oil's best-known use; the formula is a gentle, pH-balanced everyday cleanse, and Viori's own product tags list it for normal hair. If buildup is your issue, the low-pH rinse-clean chemistry is the part built for you.
The label is the answer: plant-based and naturally derived ingredients, no sulfates, parabens, phthalates, or synthetic fragrance. The scent comes only from named essential oils — chamomile, rose geranium, cedarwood, orange peel, patchouli. Every ingredient and its EWG rating is explained above.
In consumer testing across Viori bars, 92% felt softer hair after one wash (220-person panel) and 87% reported less breakage in 4 weeks (412 self-reporters, 3× weekly use).* This bar holds a 4.6 rating across 981 reviews.
Those were almost certainly cold-process soap — alkaline, pH 9–10, which reacts with hard water and films. This is not soap: a coconut-derived cleanser at pH 5.0–5.5 rinses clean, no vinegar rinse required.
Calming chamomile and soft rose geranium over a cedarwood base. Honest answer: essential-oil scents are subtler than synthetic perfume and fade sooner. That's the trade you make for a fully disclosed label — most customers say the spa-like scent during the wash is the point.
The shampoo bar cleanses and tones. The conditioner bar seals in the moisture and amino acids from the rice water and protects the cuticle between washes. For bleached hair — which is porous and loses moisture quickly — using both gives you the full repair benefit. The shampoo bar alone is a meaningful upgrade over a sulfate purple shampoo, but the duo is where the real difference shows.
Yes — most people need 2–3 washes for their hair to adjust from liquid shampoo to a bar formula. During that time your hair may feel slightly different as it clears out residue from previous products. Bleached hair typically adjusts faster than untreated hair because the cuticle is already more open. Stick with it past the first wash.
Yes — sulfate-free and pH-balanced, generally suitable for color-treated hair. Reviewers use it across the whole family.
Each bar lasts 60–80 washes, which is the equivalent of 2–3 bottles of liquid shampoo. The bar stays dry between uses when stored on a bamboo holder with airflow drainage, which extends its life significantly. If you are washing 2–3 times a week, one bar typically lasts 5–8 months.
