June 2025 in “Dermatologic Surgery” This study found that growth factor concentrate provides quicker improvements for patterned hair loss, but platelet-rich plasma offers more sustained benefits after treatment.
April 2026 in “International Journal of Current Pharmaceutical Review and Research” This study concluded that Growth Factor Concentrate was more effective than Platelet-Rich Plasma in enhancing hair growth and patient satisfaction for individuals with androgenic alopecia and telogen effluvium, while maintaining similar safety.
July 2022 in “Journal of Investigative Dermatology” This study suggests that high platelet concentrations in PRP may not be necessary for hair growth in androgenetic alopecia, and certain growth factors might negatively impact clinical outcomes.
September 2025 in “Journal of Maxillofacial and Oral Surgery” This study found that combining PRP with concentrated growth factors was more effective than PRP alone in promoting hair regrowth for patients with androgenetic alopecia.
January 2024 in “Dermatologic Therapy” This study reported that in patients with androgenic alopecia, platelet-rich plasma therapy's effectiveness in enhancing hair density and caliber was positively correlated with specific growth factor concentrations, notably glial cell-derived neurotrophic factor and platelet-derived growth factor-BB, while no significant correlations were found with demographic factors.
