TLDR Caffeine may protect hair follicles from stress-related hair loss.
A study published in the British Journal of Dermatology found that caffeine can counteract the effects of stress on hair follicles in androgenetic alopecia (AGA), a common form of hair loss affecting around 50% of men by the age of 50 years. The study showed that caffeine can protect against the negative effects of corticotropin-releasing hormone (CRH) on AGA hair follicles, suggesting a potential benefit of caffeine in the management of AGA. However, the study also noted that the optimal and stable concentration of caffeine needs to be achieved locally, not systemically, and that higher caffeine consumption may be associated with hair thinning.
