October 2018 in “Journal of The American Academy of Dermatology” This study found that platelet-rich plasma significantly increased hair count, density, and the percentage of anagen hairs in patients with androgenetic alopecia, but these improvements did not correlate with platelet or growth factor levels.
24 citations
,
November 2017 in “Aesthetic Plastic Surgery” In this study, researchers found that homologous PRP (h-PRP) significantly increased hair density more than both nonactivated (n-PRP) and activated (a-PRP) autologous PRP in patients with androgenetic alopecia, suggesting h-PRP as a potentially more effective treatment option for hair loss.

May 2017 in “Journal of Cosmetic Dermatology” This study found that platelet-rich plasma injections significantly improved hair density, thickness, and patient satisfaction in women with female pattern hair loss compared to a placebo.
136 citations
,
February 2017 in “International Journal of Molecular Sciences” This study observed that autologous platelet-rich plasma treatment improved hair count and density in areas with androgenetic alopecia compared to placebo, with differing outcomes based on the PRP collection device used.
33 citations
,
January 2017 in “Journal of Cutaneous and Aesthetic Surgery” This study found that PRP injections improved hair density, quality, and thickness in males with androgenic alopecia compared to placebo, with reported high patient satisfaction and no major side effects.
87 citations
,
September 2016 in “Dermatologic Surgery” This study found that platelet-rich plasma did not significantly improve hair mass index or hair count in women with female androgenetic alopecia, though some patients perceived benefits in hair quality.
61 citations
,
September 2016 in “Journal of Cosmetic and Laser Therapy” This study found that platelet-rich plasma was not effective in treating androgenetic alopecia in men with grade 4–6 hair loss.

,
April 2016 in “Dermatologic Surgery” This study found that platelet-rich plasma significantly increased hair density and anagen hair proportions in androgenetic alopecia patients, suggesting potential as an adjuvant therapy.
13 citations
,
January 2016 in “Journal of the Egyptian Women's Dermatologic Society (Print)” This abstract discusses platelet-rich plasma therapy for patterned hair loss but provides no new clinical results, suggesting further research is needed to determine its effectiveness.
214 citations
,
September 2015 in “Stem Cells Translational Medicine” This study found that platelet-rich plasma injections significantly increased hair count and density in patients with male pattern hair loss without major side effects, suggesting it may be a safe and effective treatment option.
66 citations
,
June 2015 in “Aesthetic Plastic Surgery” This review of 47 studies indicates that platelet preparations may significantly enhance cellular activity, wound healing, and facial aesthetic outcomes in facial plastic surgery, though potential publication bias should be considered.
183 citations

January 2014 in “BioMed Research International” This study reported that AA-PRP injections significantly increased hair count and density in individuals with pattern hair loss compared to baseline, demonstrating their potential for enhancing hair growth.
40 citations
,
February 2013 in “American Journal of Clinical Dermatology” This study found that people with androgenic alopecia, particularly women, are more prone to anxiety and depression, often adopting avoidant coping strategies, which are linked to emotional and psychological impacts rather than clinical severity.
270 citations
,
March 2012 in “Dermatologic Surgery” This study found that autologous platelet-rich plasma increased hair growth potential by enhancing dermal papilla cell proliferation and stimulating key signaling pathways in both cell cultures and mice models.
166 citations
,
August 2011 in “Dermatologic Surgery” This study found that PRP combined with dalteparin and protamine microparticles may enhance hair growth by increasing hair thickness compared to PRP alone.
