Weem vs Viviscal: How Does Rennora Beauty Compare?

You're already doing the right thing if you're comparing Weem vs Viviscal - researching before you spend. Both brands promise thicker, fuller hair. Both have loyal followings. But neither one was built with Black women in mind, and that matters more than most Weem vs Viviscal reviews will tell you.
We take a different approach here at Rennora Beauty. Our Hair Growth Serum is formulated specifically for Type 3 and Type 4 hair. You apply 39 botanicals directly to your scalp every night, directly where the problem actually starts.
Pair that with our Rennora Replenish capsules for internal support, and you've got a two-pronged system that neither side of the Viviscal vs Weem comparison can match. But we'll let you decide. Get the full breakdown below and bring out the full potential of your hair!

What Is Weem’s Hair.Skin.Nails Supplement?
Weem sells a vegan gummy supplement marketed for hair, skin, and nails all in one. Sounds great, right? Well, you know what they say about a jack of all trades…
Still, we can appreciate the simplicity and convenience. Two flavored gummies a day is easy to work into your routine. The formula features a high dose of Biotin (5,000 mcg) alongside Coconut Oil, Zinc, and a handful of vitamins.
Over a million women have tried it, and Weem vs Viviscal reviews tend to favor Weem for taste and practicality. That said, it's a general wellness gummy - not a targeted hair loss solution. Weem isn’t tailored to specific hair types, doesn't directly address inflammation/scalp health, and doesn't offer topical products.
Pros
- Affordable ($30/month)
- Vegan
- Tastes good
- Easy to take
- No shellfish or allergen concerns.
- Trustpilot rating of 4.5/5 from over 1,600 reviews
Cons
- No topical solution.
- Not formulated for any specific hair type.
- Doesn't disclose full ingredient amounts publicly (only a handful of dosages are confirmed)
- “100% money-back guarantee” is actually 60 days with exclusions for bulk and promotional orders. BBB has flagged this language.
- Results take 3-4 months
What Is Viviscal’s Hair Growth Supplement?
Viviscal is the clinical heavyweight in this Viviscal vs Weem comparison. Their tablet-based supplement features AminoMar, a proprietary marine complex made from shark cartilage and oyster extract. This is where most of the results come from.
The brand references 10 clinical trials and over 30 years of research. One published study showed a 32% increase in terminal hairs and 39% decrease in shedding after 90 days. That type of hard evidence beats anything Weem can show.
Viviscal also has a topical line of thickening shampoo, conditioner, and a serum. That also puts them a step ahead in the Viviscal vs Weem matchup. So, you can build a more well-rounded hair care regimen with Viviscal.
But like Weem, Viviscal is marketed for “all hair types” with a focus on fine and thinning hair. Nothing about curl pattern, porosity, or the specific causes of hair loss in Black women. You’re probably used to feeling like American brands overlook your needs by now - but that doesn’t mean you have to keep dealing with it.
Pros
- Clinically studied with published research
- 90-day money-back guarantee
- Topical product line available
- Widely available at Ulta, Amazon, Walmart, and dermatologist offices
- 28,000+ Amazon reviews at 4.3/5
Cons
- Has shark cartilage and oyster extract (not suitable for those with shellfish or fish allergies)
- Not vegan
- Some users report nausea and stomach discomfort
- $40/month (more expensive than Weem)
- Results take 3-6 months of daily use
- Not formulated for textured or coily hair
Viviscal vs Weem: Side-by-Side Comparison
We’re here to help you dig a little deeper than the typical Weem vs Viciscal reviews do. We’ll compare and contrast ingredients, costs, potential adverse reactions, and results side by side. Then we’ll tell you whether one of these is right for you or if it’s worth considering a third option.
Ingredient Comparison
Weem is big on Biotin with 5,000 mcg per serving. That’s way more than Viviscal's 120 mcg. But Biotin alone doesn't address the root causes of hair loss, especially for Black women dealing with inflammation from years of braids, relaxers, and heat damage.
Viviscal's AminoMar complex targets the dermal papillae cells responsible for hair growth. It’s more sophisticated, but derived from animal sources that create allergen and dietary concerns. So there’s a trade-off here.
Neither formula includes ingredients like Bhringraj (which activates dormant follicles), Saw Palmetto (which blocks DHT hormones tied to female pattern baldness), or Chebe (the moisture-locking ingredient used by Chad's Basara Arab women for centuries).
Those are exactly the kinds of botanicals that make a difference for Type 3 and Type 4 hair - and exactly what's missing from both sides of this Weem vs Viviscal debate.
Topical Solutions Available?
This is where Weem really falls short. It doesn’t make any topical products. Just gummies. That leaves a huge gap in your hair growth regimen, because you’re not getting those nutrients where they’re needed most (right in the hair follicles).
Viviscal does sell a thickening shampoo, conditioner, and leave-in serum, so they definitely have the edge here. But like we said earlier, the topicals are formulated for fine hair. If you're looking for a topical that was designed from the ground up for Black women's hair, neither brand delivers.
Clean Formula?
Weem wins here over Viviscal. Their gummies are vegan, gluten-free, and cruelty-free with no major allergen concerns. That's worth weighing in your Viviscal vs Weem decision if a clean, natural formula matters to you.
On the other hand, Viviscal's AminoMar complex contains shark cartilage and oyster extract - not clean by most standards, not vegan, and a genuine health risk for anyone with seafood allergies.
Potential Side Effects
Viviscal's marine complex can cause nausea, stomach discomfort, and allergic reactions in people sensitive to shellfish or fish. Some reviews have mentioned itching or hives, potentially from the iron content. These are rare side effects, though.
Weem's side effect profile is lighter. We see some complaints about breakouts, probably from the high Biotin dose. But there’s nothing as serious as an allergen-driven reaction.
In general, these are two well-tolerated hair-growth supplements. We just see Weem vs Viviscal reviews flag Viviscal's GI issues more frequently.
Cost Comparison
There’s a slight difference between Weem vs Viviscal in terms of what you pay - but what matters more than price alone is value for the money.
- Weem is about $30/month
- Viviscal is around $40/month
So is Viviscal worth the extra $10 every month, or can you save money by going with Weem instead? That’s where the conversation on results comes into play.
Results and Guarantees
Viviscal has the strongest clinical backing, with published studies showing measurable results at 90 days. Weem cites visible changes around month 3-4 but has no published clinical research to support the claim.
As far as guarantees go, Viviscal offers 90 days no questions asked. Weem advertises a money-back guarantee but the actual policy is 60 days with exclusions for bulk and discounted orders.
Here’s the thing, though. There’s a better option on the market for women with types 3 and 4 hair with a 120-day money-back guarantee! Let us formally introduce you to your haircare savior: Rennora Beauty.
What Makes Rennora Beauty Better Than Viviscal and Weem?
We've been honest about what both brands do well. Now here's why we believe we do it better - especially if you're a Black woman dealing with thinning edges, bald spots, or hair loss from protective styling and chemical treatments.
The Hair Growth Serum (Regular and Extra Strength)
Neither Weem nor Viviscal gives you a topical solution designed for Type 3 and Type 4 hair. Our Hair Growth Serum contains 39 botanicals - Chebe, Bhringraj, Saw Palmetto, Castor Oil, Rosemary, Stinging Nettle, Pygeum, and more. Each is chosen to reduce scalp imbalance, restore blood flow, and wake up dormant follicles. No chemicals or fillers. Women are seeing results in as little as two weeks.
Our EXTRA-Strength Serum is twice as concentrated with 45+ botanicals that penetrate deep inflammation for stubborn bald spots, completely gone edges, and damage from medical treatments. Apply it nightly, and baby hairs can start showing within two weeks. Severe areas can look totally transformed by month three.
At $27.99 for the regular serum, it costs less than both Weem and Viviscal - and it actually reaches your scalp where the problem lives. But, we do have a supplement similar to Weem and Viviscal as well.
Rennora Replenish Capsules
This is where the two-pronged approach comes in. While the serum works topically, Rennora Replenish works from the inside to fill the two nutrient gaps that disproportionately affect Black women:
- Vitamin D, because melanin blocks UV absorption
- Magnesium, the mineral Black women are most deficient in
We also include Ashwagandha, Sea Moss, Black Seed, and BioPerine for maximum absorption. All in a clean vegetarian capsule. No fillers or junk.
Topical + internal. That's something neither Weem nor Viviscal offers as a unified system built specifically for us. With over 3,100 reviews on our Hair Growth Serum alone, women are sharing amazing before-and-after photos of edges growing back, bald spots filling in, and hair finally holding length.
And we back it all with a 120-day money-back guarantee - twice as long as Weem's actual policy and 30 days longer than Viviscal's. What do you have to lose? Take the next step today.
“I started using this Hair Serum Two months ago. I was clean bald on my edges & a smooth big bald crown. Now I’m seeing baby fine white hairs on my edges & crown.”
“This has been life changing for my teenage daughter. We have been to dermatologist and they couldn’t tell us anything. We seen major results! People this stuff really works!”
“I have definitely seen improvement. I hope to see more. I would recommend this product for women like me with balding spots.”
Wrapping Up Our Weem vs Viviscal Comparison
Weem is affordable and easy to take, but it's a general wellness gummy - not a hair loss solution. Viviscal has the clinical research, but it's pricier, contains animal-derived ingredients that create real allergen risks, and wasn't built for textured hair.
If you've been reading Weem vs Viviscal reviews looking for the answer, the truth is that neither brand was designed for women like us. That's exactly why we built Rennora Beauty for Type 3 and Type 4 hair, backed by a 120-day guarantee, and trusted by nearly 100,000 women.
