Nutrafol has announced a new peer-reviewed clinical study which adds to the growing body of evidence supporting the use of nutraceuticals for female hair health
In a statement, the company reported significant improvements in hair growth rate and other objective measures of hair quality after six months of supplementation
Published inDermatology and Therapy, the prospective, open-label, randomised study followed 180 women aged 18-70 who took one of Nutrafol’s hair growth nutraceutical formulations tailored to different life stages, including postpartum and menopause
Researchers assessed participants at baseline, 90 days and 180 days using Canfield HairMetrix imaging technology alongside validated self-assessment questionnaires
The study found statistically significant improvements in linear hair growth rate (LHGR), with hair growing between 19% and 37% faster than at baseline
Participants also experienced increases in anagen (actively growing) hairs, total hair count, terminal hair count and scalp coverage during the six-month period
According to principal investigator Dr Raja Sivamani, LHGR is an important but technically demanding endpoint that is rarely measured in clinical hair research
“Measuring linear hair growth rate is rarely done because the technical demands are significant,” he said
The speed of hair growth is something patients notice and care about deeply and it’s exciting to see a multitargeting nutraceutical approach validated on this dimension
The findings were first presented at the 2026 World Congress for Hair Research in Seoul before undergoing peer review and publication
Hair thinning affects millions of women and can result from hormonal changes, ageing, nutritional status, postpartum recovery and lifestyle factors
Interest in nutraceutical interventions has grown in recent years as manufacturers seek evidence-based solutions that complement established dermatological treatments
A recent clinical review in theJournal of the American Academy of Dermatologyhighlighted the growing interest in nutritional and lifestyle interventions as adjunctive approaches to managing androgenetic alopecia, while noting that higher-quality clinical evidence remains essential
For Nutrafol, the publication represents another milestone in its clinical research programme. The company says it has now completed 26 clinical studies, including three randomised, placebo-controlled trials, evaluating its formulations across different populations and life stages
The brand said it is also the first hair growth supplement manufacturer to achieve NSF Certified for Sport certification, underscoring the growing emphasis on scientific validation and quality assurance within the hair health nutraceutical sector
