Description
A rice water conditioner bar with rosemary and biotin for hair that breaks, sheds, or won't grow.
This conditioner bar delivers rosemary, biotin, and Longsheng rice water directly to the strands that need it most — thin, fragile mid-lengths and ends that snap instead of grow. The same fermented rice water the Red Yao women of southern China are known for using as their primary hair treatment for centuries.
Rosemary brings circulation to the scalp. Biotin reinforces keratin structure. Rice water fills in damage with amino acids and inositol. Together, they strengthen hair from root to tip so it grows longer before it breaks.
Scent: Herbal and green — matches the Rosemary & Biotin Shampoo Bar. Rosemary-forward with a clean, earthy finish.
What it feels like: Smooth, lightweight conditioning. Detangles gently without pulling. Hair dries with more body and less breakage at the ends.
Thinning hair responds to consistency. Use the full shampoo + conditioner pair for at least 2 weeks before judging results.
1. After shampooing, squeeze excess water from your hair.
2. Glide the bar directly down mid-lengths and ends, or work it between your palms first.
3. Comb through with fingers or a wide-tooth comb to distribute.
4. Leave for one to two minutes, then rinse with cool water.
5. Keep it off the roots if your scalp runs oily.
6. Store on a bamboo holder or dry surface between uses.

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!!
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!
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
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!
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
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.
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!
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.
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. :)
About 2 weeks i got this castor oil shampoo bar and im soo in love!! This is my first time using a shampoo bar and this is a game changer for me!! Goodbye dry scalp, and rough dry hair... Hello hydration, shine , soft hair and omg,smells sooo good!! I love the way its so easy to use. Lathers up so effortlessly, Also the way its lasting is above and beyond my expectations!! I definitely recommend this shampoo bar , if you haven't tried it yet, you should!!
Love, love, love, the way it lathers! It makes my hair feel so clean and so light and soft. I've never felt that with other products. I will definitely be a continuous customer and be recommending this product to my family and friends.
I love every product this company makes. Honestly such amazing hair products. Will forever buy from them. Just got my mom a gift set because she loves it too.
You are not growing slowly. You are losing it at the ends as fast as you make it at the root.
0 1
The stall
Your hair sits at the same length for years. It is still growing — it is breaking off at the same rate, so the length never shows.
0 2
Breakage disguised as shedding
Long strands with a white bulb are shed hairs, and that is normal. Short pieces with no bulb are broken ones, and that is a strength problem you can do something about.
0 3
Conditioner that costs you volume
Thin hair still needs conditioning, but most conditioners leave enough residue to flatten the root. So people skip it, and the ends pay.
THE ANSWER
Protect the part that breaks.
The Rosemary Biotin Conditioner Bar puts the same actives on the mid-lengths and ends, where thinning hair actually fails.
Growth happens at the root, but length is kept or lost at the ends. This bar carries rosemary leaf oil, biotin and Longsheng rice water down the strand, with hydrolyzed rice protein reinforcing the fibre from the inside rather than coating the outside. It gives enough slip to get a comb through wet hair without a fight — which matters, because a good share of breakage on fine hair happens during detangling. And it rinses clean, so nothing accumulates at the root to flatten the volume you are trying to build. Work it from the ears down, leave it a minute, rinse. If your scalp runs oily, keep it off the roots entirely.
Most rice water proteins are too large to enter the hair shaft — at 13,000–30,000 Daltons they sit on the surface and rinse away. Hydrolyzed Rice Protein is broken down to peptides below ~1,000 Daltons, small enough to reach the cortex, where research indicates they deposit preferentially on compromised areas, improving tensile strength and reducing breakage under combing stress. The result is a strand that bends without snapping — not a coating, but internal reinforcement.
Resilience That Stays After Rinsing
Inositol, a carbohydrate abundant in fermented rice water, is the reason the effect does not wash out. Studies of rice-water treatment report that inositol remains inside the fiber after rinsing, continuing to reduce friction and protect the strand between washes rather than acting only while the product is on the hair.
Rosemary Oil, Measured Against The Standard
In a 2015 randomised trial, rosemary oil was compared directly with 2% minoxidil in androgenetic alopecia over six months. Both groups showed a significant increase in hair count at the six-month mark, with no meaningful difference between them, and the rosemary group reported less scalp itching. That is one trial, not a guarantee — but it is why rosemary appears here as an active rather than a scent.
Biotin, Honestly
Biotin is a cofactor in keratin production, and deficiency causes hair loss that resolves when the deficiency is corrected. Evidence that supplemental biotin thickens hair in people who are not deficient is thin, and we are not going to pretend otherwise. It is in the formula because it is part of the keratin pathway and it is well tolerated topically, not because a bar can promise regrowth.

FAQ
GOOD TO KNOW BEFORE YOU BUY.
Not if you keep it off the roots. Apply from the ears down and rinse thoroughly. There is no silicone in it, so there is nothing left behind to accumulate and flatten the root over the week.
If your hair breaks, yes. The shampoo works at the scalp; this works on the mid-lengths and ends, which is where thin hair actually gives out. Using both is how you keep the length the shampoo helps you grow.
It carries the same actives as the shampoo bar — rosemary, biotin, rice water — rather than just adding slip. And it conditions through the strand instead of coating it, so fine hair gets softness without the weight.
Sixty to eighty uses for most people, depending on hair length and how much you use. Keeping it dry between washes on a holder makes more difference to bar life than anything else.
Yes. No sulfates, no harsh detergents — nothing in it strips tone.
Herbal and green, matched to the Rosemary Biotin Shampoo Bar. Rosemary-forward with lavender and chamomile underneath.
Yes, it works with any shampoo. You will just get the rosemary and biotin on your lengths rather than at the scalp as well.
No. Hair you see in the shower was already shed and is being released as you detangle; conditioner makes that gentler, not more frequent. Skipping conditioner on fragile hair generally causes more breakage, not less.
