Leading hair health supplement brand Nutrafol has released findings from its latest randomized controlled trial (RCT) on Nutrafol Men, further solidifying its commitment to science-backed product development.
The study, which was published in the Journal of Cosmetic Dermatology, confirms the product’s safety, tolerability, and effectiveness in improving hair growth and quality without compromising sexual performance.
Funding was provided by Nutraceutical Wellness Inc., the company that owns and operates the Nutrafol brand.
Clinical trial findings
“The trial found that men in the active treatment group experienced statistically significant improvements in hair growth and quality compared to the placebo group,” said Dr. Isabelle Raymond, SVP of Science & Research at Nutrafol.
Specifically, “85% of participants in the active group reported a positive response regarding how effective the supplement was in slowing down their hair thinning, compared to just 55% in the placebo group”, she said.
According to Nutrafol’s press statement announcing the findings, “Nutrafol Men helps maintain existing hair and is clinically proven to improve hair growth,” and the recent RCT results join two other clinical studies that support the product’s proven efficacy.
The study concluded that Nutrafol Men addresses key root causes of hair thinning, offering a clinically studied nutraceutical solution.
“Our team was keen on pushing for the publishing of the RCT because we are dedicated to always improving, innovating, and pursuing the highest research to back our product,” said Dr. Raymond.
A differentiated approach in the hair supplement industry
Nutrafol positions itself as a pioneer in the hair wellness space by prioritizing scientific rigor and safety. “Most products in the [wider hair wellness] category are not 100% drug-free or cause unwanted side effects. Nutrafol’s 100% drug-free, standardized ingredients target key root causes of thinning for visibly thicker, fuller hair growth and scalp coverage, without compromising sexual performance – a common side effect of many conventional solutions,” said Dr. Raymond.
Dr. Neal Bhatia, a primary investigator on the trial, stated in the company’s press release that men are often taught hair thinning and shedding is largely hereditary, but “Nutrafol has pioneered a new way of approaching and explaining the science of hair wellness, ensuring that customers are receiving safe, effective products that meet their hair wellness goals without compromising their quality of life”.
Commitment to scientific integrity and transparency
Nutrafol is also working to emphasize transparency in an industry often characterized by fleeting wellness trends “that lack scientific backing, which is why we take a rigorous clinical approach to improving our products with scientific investment,” Dr. Raymond stated. “Each formulation is built on years of clinical research, working closely with leading dermatologists and other medical professionals to develop products that meet the highest standards of efficacy and safety.
“We value transparency and are always happy to share our clinical studies and address any questions from both potential and existing customers,” she added.
In the company’s press statement, Cindy Gustafson, Nutrafol CEO, reinforced the company’s research-driven approach: “We strive to deliver best-in-class products with proven results, and this study is a testament to the extensive research and development behind every Nutrafol formula.”
She concluded, “By prioritizing bio-specific formulations tailored to address hair thinning and testing them within their intended populations, we ensure efficacy and relevance,” and “our dedication to conducting randomized controlled trials and comprehensive safety assessments means our customers can trust Nutrafol to be both effective and safe.”
