    TLDR Placenta products might help with hair loss, but more research is needed.
    This systematic review evaluates the clinical evidence for the efficacy of placental products in treating hair loss, analyzing three human trials with 127 participants. The studies suggest that placenta products may be as effective as minoxidil, particularly in women with androgenetic alopecia or postpartum telogen effluvium. However, the quality of evidence is low, and the lack of detailed information on the concentration and composition of placenta derivatives limits the conclusions. The review emphasizes the need for more rigorous, well-designed randomized controlled trials to better understand the potential of placenta derivatives in hair loss treatment, with a focus on well-defined products and safety assessments.
