November 2024 in “Stem Cell Research & Therapy” This study found that human umbilical cord mesenchymal stem cells (hUCMSCs) promoted hair regeneration in androgenetic alopecia model mice by activating Wnt/β-catenin signaling, enhancing hair follicle stem cell proliferation, and reducing dermal papilla cell apoptosis.
July 2024 in “Journal of the American Academy of Dermatology” Botulinum toxin may help treat male pattern baldness.
June 2024 in “Dermatology and therapy” This study reviewed recent advancements in using botulinum toxin for treating androgenetic alopecia and emphasized the need for further research to determine the most effective injection sites and depths, as current strategies show inconsistent results.
May 2024 in “Dermatologic surgery” In this study involving 15 women with alopecia, subcutaneous scalp injections of platelet-rich plasma every four weeks for three sessions led to increased hair and hair follicle density at 24 weeks, with common side effects being local swelling and pain.
August 2023 in “Journal of Cosmetic Dermatology” In this study, injecting two different concentrations of botulinum toxin A was found to be safe and effective for treating androgenetic alopecia in Egyptian men and women, with improvements in hair grade and vellus hair density observed over six months.
August 2023 in “Journal of Dermatological Treatment” This systematic review concluded that mesotherapy shows potential for improving hair growth outcomes, yet lacks standardized regimens and requires further large-scale trials to establish its efficacy and safe use.
December 2022 in “Plastic and Reconstructive Surgery” This study found that autologous platelet-rich plasma significantly improved hair follicle number, thickness, and density in patients with androgenic alopecia compared to placebo, with high reported patient satisfaction.

August 2020 in “Dermatologic Surgery” In this study, human ADSC-CM treatment following nonablative fractional laser significantly increased hair density and volume in patients with androgenetic alopecia without any reported adverse effects.
15 citations
,
April 2020 in “Journal of The American Academy of Dermatology” In this study, intradermal injection of botulinum toxin was associated with increased hair growth in men with androgenetic alopecia through the suppression of TGF-β1 secretion from dermal papilla cells.

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.
16 citations
,
December 2016 in “Molecular Medicine Reports” This study found that platelet-rich plasma may influence the proliferation of human hair dermal papilla cells by affecting gene expression related to the cell cycle.
