Quick Answer: Both Nutrafol and Viviscal have clinical evidence supporting hair growth, but they take different approaches. Nutrafol ($79-$88/month) is a comprehensive multi-ingredient formula targeting stress, hormones, and inflammation. Viviscal ($33-$50/month) is simpler, built around its patented marine protein complex (AminoMar). Choose Nutrafol if you suspect stress or hormones are contributing to your hair loss. Choose Viviscal if you want a more affordable, well-studied option for general thinning. Both require 3-6 months of consistent use.
Nutrafol and Viviscal dominate the hair growth supplement market, and for good reason—they're among the few with actual clinical studies behind them. But at very different price points and with very different formulas, choosing between them isn't straightforward.
I've analyzed the ingredients, research, cost, and user feedback for both products to help you make an informed decision.

Nutrafol: Deep Dive
Nutrafol positions itself as a "physician-formulated" nutraceutical that targets the "root causes" of hair thinning: stress, hormones, environment, nutrition, and metabolism. It's a complex formula with over 21 active ingredients.
Key Ingredients
- Synaplex (ashwagandha + other adaptogens): Targets cortisol and stress-related hair thinning. Ashwagandha has solid evidence for lowering cortisol levels
- Saw palmetto: Natural 5-alpha reductase inhibitor that may reduce DHT levels. Less potent than finasteride but with fewer side effects
- Marine collagen: Provides amino acids for keratin production and dermis support
- Curcumin: Anti-inflammatory that may reduce follicle inflammation (standardized for high absorption)
- Tocotrienols (vitamin E complex): Antioxidant protection for follicle cells; one study showed 34% increase in hair count
- Biotin: 3,000 mcg per serving for keratin support
- Horsetail extract: Natural source of silica, which supports hair structure
- Resveratrol: Antioxidant and anti-inflammatory compound
Nutrafol Clinical Evidence
- 2018 study (Journal of Drugs in Dermatology): Women taking Nutrafol showed significant improvement in hair growth rate and volume at 6 months vs placebo
- 2020 study: Nutrafol improved hair growth, quality, and thickness with self-perceived improvements in 80%+ of participants
- Dermatologist recommendation: The #1 dermatologist-recommended hair growth supplement brand
Note on Nutrafol studies: Most Nutrafol clinical studies are company-sponsored, which doesn't invalidate them but is worth knowing. Independent replication would strengthen the evidence base.
Viviscal: Deep Dive
Viviscal has been on the market since the 1990s and has one of the longest track records of any hair supplement. Its formula is simpler and centered on a single proprietary ingredient: AminoMar.
Key Ingredients
- AminoMar (marine protein complex): Proprietary blend of shark cartilage powder and mollusk powder. Provides glycosaminoglycans and marine-derived proteins that nourish hair follicles from within
- Biotin: 120 mcg per serving (much lower than Nutrafol)
- Vitamin C: Antioxidant that supports collagen synthesis
- Iron: Essential for oxygen delivery to follicle cells; deficiency is a common cause of hair thinning
- Zinc: Supports hair tissue growth and repair; keeps oil glands functioning
- Niacin (B3): Supports blood circulation to the scalp
- Horsetail extract: Natural silica source (in some formulations)
Viviscal Clinical Evidence
- 2012 randomized, double-blind study: Significant increase in hair count and decrease in hair shedding at 3 and 6 months vs placebo
- 2015 study (Dermatology Research and Practice): Viviscal users showed significant improvement in terminal hair count at 3 and 6 months
- 2015 study on women: Significant increase in hair volume, scalp coverage, and thickness of hair body after 3 months
- 25+ years of research: AminoMar has been studied in multiple countries with consistent positive results
Viviscal's research base is notably strong for a supplement—multiple independent and semi-independent studies with consistent results across populations.

Who Should Choose Which?
Choose Nutrafol If:
- You suspect stress is contributing to your hair loss (telogen effluvium)
- You want a DHT-blocking component without prescription finasteride
- You prefer a comprehensive, multi-targeted approach
- Budget isn't your primary concern
- You're looking for additional wellness benefits (adaptogen support, anti-inflammation)
- You're a woman experiencing postpartum or perimenopause thinning
Choose Viviscal If:
- You want a more affordable option ($33-50 vs $79-88/month)
- You prefer a simpler, more studied formula with a long track record
- You're experiencing general thinning without a specific hormonal cause
- You don't need or want DHT-blocking ingredients
- You have iron deficiency contributing to hair loss
- You want a supplement with more independent research
Cost Analysis: Is Nutrafol Worth 2x the Price?
| Timeframe | Nutrafol Cost | Viviscal Cost | Difference |
|---|---|---|---|
| 1 month | $79-$88 | $33-$50 | $29-$55 |
| 6 months | $474-$528 | $198-$300 | $174-$330 |
| 1 year | $948-$1,056 | $396-$600 | $348-$660 |
| 2 years | $1,896-$2,112 | $792-$1,200 | $696-$1,320 |
The price difference is significant, especially given that hair supplements must be taken long-term for sustained results. Over two years, you could save $700-$1,300 with Viviscal. The question is whether Nutrafol's additional ingredients—particularly the adaptogens and DHT blockers—justify the premium for your specific situation.
Budget alternative: You could take Viviscal ($35/month) plus separate ashwagandha ($12/month) and saw palmetto ($10/month) supplements for roughly $57/month—getting most of Nutrafol's key ingredients for about 30% less.
Results Timeline: What to Expect
Month-by-Month (Both Supplements)
- Month 1: No visible change; ingredients building in your system
- Month 2: Reduced shedding may be noticeable; less hair in the shower drain
- Month 3: Baby hairs appearing; improved hair texture and shine; clinical studies start showing measurable improvements here
- Month 4: Continued improvement in density; existing hair feels thicker
- Month 5-6: Most significant visible results; photos show noticeable difference in coverage and thickness
- Month 6+: Maintenance phase; continued improvement at a slower rate
Reality check: Neither Nutrafol nor Viviscal will reverse significant male or female pattern baldness. They work best for diffuse thinning, stress-related hair loss, and nutritional deficiency-related thinning. If you have substantial hair loss, consider FDA-approved treatments (minoxidil, finasteride) alongside—or instead of—supplements.
The Bottom Line
- Both work: Nutrafol and Viviscal both have clinical evidence supporting hair growth improvement
- Different strengths: Nutrafol is more comprehensive; Viviscal is simpler and better-studied independently
- Nutrafol for stress/hormonal thinning: Ashwagandha and saw palmetto address cortisol and DHT
- Viviscal for general thinning: Proven marine protein complex with iron support
- Viviscal is much cheaper: ~$35/month vs ~$85/month for Nutrafol
- Allow 6 months: Both require patient, consistent daily use for meaningful results
- Not a replacement: For pattern baldness, FDA-approved treatments (minoxidil, finasteride) remain the most effective options
My recommendation: start with Viviscal if budget is any factor. If after 6 months you want more aggressive support—or if you identify stress or hormones as a factor—consider upgrading to Nutrafol or adding targeted supplements. The best supplement is the one you'll actually take consistently, and a lower price point helps with long-term compliance.
