Scientists find link between workouts and hair loss
A new medical review published in the journal JAAD Reviews examined the effect of whey protein on hair growth and loss. Researchers emphasize that the supplement does not directly cause alopecia, but may accelerate hair thinning in men with a genetic predisposition to androgenetic alopecia. Experts advise not to panic, but to consider this factor when assessing the problem.
A new medical review published in the September 2026 issue of the journal JAAD Reviews examined the effect of whey protein on hair growth and loss. Researchers emphasize that whey protein does not directly cause alopecia. However, popular theory and biological models suggest that active consumption of this supplement may accelerate the process of hair thinning in men genetically prone to androgenetic alopecia. The study explored the possible impact of the component on hormones, insulin-like growth factor 1 (IGF-1), and androgenic pathways. Whey protein is one of the most popular sports supplements for building muscle mass and recovery after workouts. To date, there are no convincing clinical trials proving whey's direct role in baldness, and available data remain limited. Dr. Emrah Cinik, founder of the Dr Cinik Hair Clinic, noted that people should not panic and throw away sports nutrition due to frightening headlines. He explained that the review's interest lies in attempting to understand the biological mechanisms linking whey and hair condition in certain individuals. If a person has a genetic predisposition to alopecia and notices changes after a change in diet, supplements, and exercise routine, it is reasonable to consider all these factors.
