April 2023 in “Journal of Cutaneous and Aesthetic Surgery” In this study, researchers analyzed the occipital donor area for hair transplantation among men aged 50–55 with androgenetic alopecia and found that while most subjects met standard safe donor area criteria, individual variations suggest a conservative approach to donor area selection.
May 2020 in “Hair transplant forum international” This study found that, among Indian men aged 50-55 with androgenetic alopecia, 78% of occipital donor areas fitted standard safe donor area criteria, but 22% did not, indicating a need for tailored selection in hair transplants.
April 2019 in “Journal of Investigative Dermatology” This study found that induced COX-2 expression in adult transgenic mice led to hair follicle miniaturization and enlargement of sebaceous glands, and suggests that targeting the PGD2 pathway might reverse these effects.
February 2024 in “Molecules/Molecules online/Molecules annual” In this study, NMN was found to reverse hair follicle atrophy, thinning, and sparsity in mice induced by DHT, and significantly decreased DHT-induced inflammation and oxidative stress in cultured human dermal papilla cells, enhancing hair growth-related markers.
January 2020 in “International Journal of Trichology” This case study reported two instances of female androgenetic alopecia with male pattern reversed after surgical removal of an ovarian tumor.
January 2022 in “Clinical Cases in Dermatology” This paper reviews treatment options for alopecia in hypothyroidism, noting that while hormone replacement can restore hair growth, additional treatments like PRP and oral minoxidil may help, though further research is needed.
December 2024 in “Indian Journal of Dermatology Venereology and Leprology” Atypical male hair loss may not respond to usual treatments.

February 2004 in “Medical Hypotheses” This article reviews the theory that certain cultural practices, like specific haircuts, contribute to common baldness but reports no new clinical findings.
August 2022 in “Journal of drugs in dermatology” This review discusses the potential role of hormone therapies in preventing or reversing age-related aesthetic changes in postmenopausal women and reports no clinical results; it suggests these treatments may be safely and effectively used by dermatologists.
August 2025 in “Stem Cell Reviews and Reports” This study demonstrated that adipose derived stem cells nanovesicles enhanced hair growth and reduced sebum secretion in androgenetic alopecia, showing effects comparable to minoxidil in laboratory and mouse models.
July 2022 in “Zenodo (CERN European Organization for Nuclear Research)” This article discusses various shampoos for thinning hair and dry shampoos, noting their ingredients and potential benefits, but reports no new clinical results.

,
January 2004 in “Dermatologic Clinics” This article discusses nutritional contributions to hair health and highlights the need for identifying risk factors for deficiencies but reports no new clinical findings.
242 citations
,
February 2016 in “Science” This research found that Foxc1 transcription factor and COL17A1 are critical in regulating quiescence and hair thinning in hair follicle stem cells, with aging-related DNA damage leading to hair loss.
2 citations
,
February 2021 in “Developmental Cell” This study reports that aging in human skin involves early photo- and inflammation-related cellular changes, and suggests restoring KLF6 and HES1 expression might reverse some of these age-associated changes.
122 citations
,
April 2020 in “American Journal Of Pathology” This review discusses the multiple factors contributing to skin aging, including cellular changes and environmental influences, and highlights its recognition as a disease with significant implications beyond cosmetic concerns, without reporting new research results.
May 2022 in “Journal of the Egyptian Women's Dermatologic Society (Print)” This article discusses the clinical features and treatment options for common types of hair loss in women and reports no new clinical results.
This study found that neurotrophins produced by balding dermal papilla cells inhibited both their proliferation and hair follicle growth in vitro, suggesting a potential role in androgenetic alopecia.
12 citations
,
October 1976 in “The BMJ” This abstract reports an influenzalike illness with varying antibody titers observed in a woman and her husband, but it does not provide broader clinical findings.

December 2011 in “British Journal of Dermatology” The researchers reported that a novel leave-on treatment containing caffeine, niacinamide, panthenol, dimethicone, and an acrylate polymer significantly increased the diameter and improved the mechanical properties of scalp hair fibers, suggesting it may help mitigate thinning hair.
4 citations
,
July 2014 in “Journal of Investigative Dermatology” This study suggests that age-related regenerative decline in hair follicles may be due to an imbalance of signals affecting stem cell activation, with follistatin potentially promoting renewal.
December 2023 in “Biological & pharmaceutical bulletin” This study found that combining lecithin reverse wormlike micelles with isopropyl myristate enhanced the skin permeability of a model hydrophilic drug, facilitated by interactions with sebum in hair follicles.
