    TLDR PRP therapy for alopecia shows inconsistent results due to natural variability in growth factor secretion by platelets.
    The study evaluated the secretion of growth factors (GFs) by platelets in platelet-rich plasma (PRP) samples from female alopecia patients, finding significant variability in GF secretion across samples. Despite using two different FDA-cleared devices to prepare PRP, the heterogeneity in GF secretion remained consistent, suggesting that the variability is inherent to the platelets themselves. This heterogeneity could contribute to the inconsistent clinical responses observed in PRP therapy for alopecia, as the balance between growth-promoting and inhibiting factors is crucial for effective treatment.
