October 2021 in “Journal of Cosmetic Dermatology” This study found that microneedling monotherapy significantly increased hair count more than topical minoxidil in androgenetic alopecia, with combination therapy of microneedling and minoxidil being even more effective. Further research is needed to evaluate microneedling's safety and efficacy as a monotherapy.
This study found that garlic exosomes induced hair growth in rats by increasing anagen follicle counts and activating multiple signaling pathways, including Wnt-1, β-catenin, and TGF-β1.
August 2024 in “Saudi Journal of Medical and Pharmaceutical Sciences” In this study, PRP combined with minoxidil was found to be more effective in improving hair counts in androgenetic alopecia patients compared to minoxidil alone or with dermaroller, showing significant improvements at both 3 and 5 months.
December 2023 in “Medical Times” In this study, combining stromal cells and PRP resulted in a significantly higher cell count and volume than using a saline group, suggesting increased potential efficiency; however, clinical outcomes need further evaluation.

,
October 2019 in “Dermatologic Surgery” This study found that platelet-rich plasma was effective for hair regrowth in women with androgenic alopecia, though less so than minoxidil, but it was associated with improved quality of life responses.
6 citations
,
January 2021 in “Journal of the American Academy of Dermatology” This review discusses the use of platelet-rich plasma for alopecia treatment and notes a lack of data on the consistency of FDA-approved PRP devices in clinical settings.

,
January 2025 in “OBM Geriatrics” This study highlights the role of platelets in immune interactions and severe adenovirus infection, noting that activated platelets have a shorter lifespan. Results suggest potential for developing therapies targeting platelet senescence and immunologic mechanisms.
January 2024 in “E3S Web of Conferences” In this study, stray cats in Bogor exhibited skin and fur issues, abnormal respiratory and heart rates likely due to stress, increased eosinophils, low platelet counts suggesting parasitic infestation, and hyposthenuria in urine tests potentially linked to low water intake or fasting.
39 citations
,
March 2019 in “Dermatologic Surgery” This study's meta-analysis reported that PRP injections significantly increased hair density compared to baseline and placebo in androgenetic alopecia patients, supporting its use as a beneficial treatment.

April 2020 in “British Journal of Dermatology” PRP treatment helps 70.1% of hair loss patients after two sessions.
April 2023 in “Egyptian journal of Immunology” This study found that human platelet lysate supported mesenchymal stem cell growth as effectively as fetal bovine serum, while fetal bovine serum was more effective for hepatocyte proliferation.
