Clinical Evidence for Real Hair Growth
Every ingredient in Folly's formula is supported by rigorous clinical research published in peer-reviewed medical journals. We don't just make promises—we deliver proven results.
Gold Standard Research Methodology
Our ingredient selection is based exclusively on randomized, double-blind, placebo-controlled trials—the highest standard of scientific evidence.
Randomized
Participants are randomly assigned to treatment or placebo groups, eliminating selection bias and ensuring reliable results.
Double-Blind
Neither participants nor researchers know who receives the treatment, preventing expectation bias and ensuring objective measurements.
Placebo-Controlled
Results are compared against an inactive placebo, proving that improvements are due to the ingredient, not psychological effects.

Efficacy and safety of pumpkin seed oil for androgenetic alopecia in men: A randomized, double-blind, placebo-controlled trial
Authors: Cho YH, Lee SY, Jeong DW, et al.
KEY RESULT
Significant improvement in hair growth with measurable increases in hair count and thickness compared to placebo
This randomized, double-blind, placebo-controlled study demonstrated that oral supplementation with pumpkin seed oil significantly improved hair growth in men with androgenetic alopecia. Participants showed meaningful increases in hair count and thickness compared to placebo, suggesting pumpkin seed oil’s effectiveness as a natural therapeutic option for male pattern hair loss through its anti-androgenic and anti-inflammatory properties.

Authors: Cho YH, Lee SY, Jeong DW, et al.
KEY RESULT
40% increase in mean hair count after 24 weeks of daily supplementation
A 24-week randomized, placebo-controlled trial found that men taking 400mg of pumpkin seed oil daily experienced a 40% increase in mean hair count compared to baseline. The study demonstrates pumpkin seed oil’s potential to inhibit 5-alpha reductase and promote hair growth through its phytosterol content, particularly β-sitosterol, offering a safe and effective natural alternative for treating hair loss.

Study: NCT06174441
KEY RESULT
Synergistic effects on keratin production, collagen synthesis, and follicle health
This clinical trial investigates the synergistic effects of methylsulfonylmethane (MSM), essential vitamins, and zinc on hair growth parameters. MSM supports keratin production and collagen synthesis, while zinc and vitamins work together to regulate sebum production, support follicle health, and maintain the hair growth cycle. The combination addresses multiple pathways involved in hair health and growth.

Authors: Medical Journals Sweden
KEY RESULT
Enhanced hair density through stimulation of anagen growth phase
This randomized controlled trial evaluated the efficacy of grape seed extract in promoting hair growth. The study showed that grape seed proanthocyanidins stimulate hair follicle cells and promote the anagen (growth) phase of the hair cycle. The antioxidant and anti-inflammatory properties of grape seed extract contribute to improved scalp health and enhanced hair density.

KEY RESULT
Comparable hair regrowth to minoxidil with fewer reported side effects
This comparative study evaluated the efficacy of a rosemary and myrtus extract combination against minoxidil for treating androgenetic alopecia. Results demonstrated that the herbal extract combination showed comparable effectiveness to minoxidil in promoting hair regrowth, with the added benefit of fewer side effects. Rosemary extract’s anti-inflammatory and antioxidant properties support scalp health and stimulate hair follicle activity through improved microcirculation.

KEY RESULT
Improved insulin sensitivity and hormonal balance in women with PCOS
This study examined the therapeutic effects of chromium supplementation in women with polycystic ovary syndrome (PCOS), a condition frequently associated with hair thinning and loss. Chromium supplementation demonstrated improvements in insulin sensitivity and hormonal balance—key factors in PCOS-related hair loss. The findings support chromium’s role in addressing the metabolic and hormonal pathways that contribute to hair thinning in women with PCOS.
