November 2024 in “bioRxiv (Cold Spring Harbor Laboratory)” The study investigated the effects of two commercial products containing exosomes on hair growth and regeneration using human hair follicle cultures. One product contained exosomes from stem cells derived from the umbilical cord lining, while the other used exosomes from bovine colostrum loaded with growth factors and cytokines. Results showed that the bovine colostrum-derived exosomes significantly enhanced hair bulb growth and dermal papilla regeneration compared to the stem cell-derived exosomes, which performed similarly to untreated controls. This suggests that exosomes from bovine colostrum, enriched with growth factors and cytokines, could be effective in slowing hair loss and promoting new hair growth.
