Nutrafol becomes first and only hair growth supplement brand to earn NSF Certified for Sport®, enters multi-year partnership with Major League Baseball

Today, Nutrafol announced its first-ever, multi-year sports partnership with Major League Baseball (MLB) as its Official Hair Growth Partner. The strategic partnership, which will launch with the 2025 Postseason and extend into the 2026 regular season, is rooted in the brands’ shared values and will center around fan-first moments that celebrate the game and hair health, on and off the field.

Nutrafol will now also uniquely support players as the first and only hair growth supplement brand to earn NSF Certified for Sport® - the only independent third-party certification program recognized by MLB. By achieving this certification, Nutrafol’s hair growth supplements are the only hair growth supplements tested and verified for MLB players’ safe use.

“Partnering with Major League Baseball is a natural fit for Nutrafol, as we are both laser-focused on serving our customers and fans as well as meeting the highest standards in all that we do - as now seen by our hair growth supplements earning the top level of certification from NSF,” said Cindy Gustafson, Chief Executive Officer at Nutrafol. “As leaders in hair health, we can’t wait to begin our partnership during one of the most exhilarating times of the season, bringing hair wellness into the national conversation in a way that’s both impactful and inspiring.”

The multi-year partnership between Nutrafol and MLB will begin during the 2025 Postseason with the “Hats Off” campaign – celebrating both the game and hair health through everything from fan experiences to custom content. Rooted in the tradition of taking a hat off to mark exciting moments during games, the campaign will run across Nutrafol’s and MLB’s channels, including social, digital and MLB Network.

As part of the 2025 campaign, Nutrafol and MLB will introduce:

• Postseason Testimonials: Nutrafol will enlist a roster of recognized baseball personalities as ambassadors to spotlight their personal hair journeys, and why they trust Nutrafol’s clinically tested supplements for hair health.
• Ballpark Fan Experiences: A dedicated in-stadium “Hats Off” section at select ballparks across the country will spark in-game fan engagement as well as create surprise-and-delight moments throughout the Postseason.
• Custom Integrations: Nutrafol will debut a “Hats Off” digital highlight series, showcasing standout plays or comebacks. Brand signage will also backdrop reliever warm-ups and epic entrances in MLB bullpens.
• Hats Off to the World Series™ Sweepstakes: A new sweepstakes will launch on September 29, lasting until 11:59pm ET on October 15, where baseball fans can enter for the chance to win a grand prize package that includes World Series tickets, a year’s supply of Nutrafol, merch, and more. For more information on the sweepstakes including how to enter, please visit nutrafol.com on September 29.

In 2026, Nutrafol and MLB will expand on the 2025 Postseason campaign, with a focus on “The Long Game.” From Spring Training in February, through the 162-game regular season and month-long Postseason, baseball fans and teams are as committed as they come. Mirroring that dedication, this campaign will educate around long-term hair health maintenance and holistic wellbeing. Nutrafol will activate a fleet of baseball personalities, or “Hair Captains,” to tell their hair journeys and experiences using Nutrafol’s hair growth supplements; the campaign will also cast a light on Nutrafol’s whole-body approach to hair health, targeting multiple root causes of hair thinning - from stress and hormones, to nutrition and lifestyle.

“Nutrafol is a renowned brand that helps over a million people across the country, and we know this partnership will be unique and impactful. In fact, in recent years the MLB health and safety team has reported that many players have sought out certified hair growth supplements - and now they finally have a trusted option,” said Uzma Rawn Dowler, MLB Chief Marketing Officer and Senior Vice President, Global Corporate Partnerships. “We’re looking forward to encouraging everyone at our games, from players to fans, to take their hats off and confidently celebrate with us as Nutrafol joins MLB as our Official Hair Growth Partner.”

Earning NSF Certified for Sport®

Nutrafol’s partnership with MLB follows its Hair Growth Nutraceuticals’ (Nutrafol Women, Men, Postpartum, Women’s Vegan, and Women’s Balance) newly earned certification from NSF’s Certified for Sport® program - the highest bar in safety and quality testing. This certification builds on the hair growth supplements also recently earning NSF Contents Certified, following a rigorous product evaluation by the trusted public health organization.

Designed to help both athletes and consumers make more knowledgeable decisions when choosing supplements, the Certified for Sport® program from NSF tests products for nearly 300 athletic banned substances as well as potentially harmful levels of specific contaminants like lead and arsenic. Product formulation, label claims, and Good Manufacturing Practices (GMP) compliance are also verified as part of this supplement certification.

In addition to MLB, Certified for Sport® is the only certification recognized by the National Hockey League, the Canadian Football League, and the United States Anti-Doping Agency (USADA); it is also recommended by the NFL, NBA, PGA Tour, LPGA, CCES, ASPDA, iNADO, Ironman, NASCAR, Taylor Hooton Foundation and many other organizations seeking to mitigate the risks of contaminated dietary supplements.

“NSF welcomes Nutrafol to the Certified for Sport® program as the first and only hair growth supplement brand to reach our highest level of certification for athletes and active consumers,” said David Trosin, Senior Director, Nutrition and Wellness at NSF. “NSF is focused on protecting and improving human health worldwide. By meeting our rigorous requirements for both Contents Certified and Certified for Sport®, Nutrafol is demonstrating its commitment to clean sport as well as quality and safety for its hair growth supplements.”

On top of evaluation via NSF’s program, every Nutrafol formula undergoes extensive testing - from safety assessments by expert toxicologists, to validating nutrient and ingredient amounts and ensuring compliance with FDA regulations and GMP. Nutrafol also has multiple clinical studies conducted on different populations to support the efficacy of its hair growth nutraceuticals, which include level one and level two clinical evidence – the industry gold standard for claims substantiation – and are conducted by multiple clinical research organizations and physicians.

As the #1 dermatologist-recommended hair growth supplement brand* and U.S. News & World Report's Top Vitamin for Hair Growth for two consecutive years, Nutrafol continues to be recognized as the category leader.
