April 2016 in “Food Science and Biotechnology” This study found that Oriental melon leaf extracts promoted hair growth in a mouse model and cultured human hair follicles, suggesting potential use as a treatment for hair loss.
April 2021 in “Advances in Cosmetic Surgery” Hair restoration can be achieved through non-surgical treatments like minoxidil, antiandrogens, phototherapy, and PRP procedures, or through surgical methods like hair transplantation. Continued treatment is needed to maintain results, and full results are visible after 12-18 months.
February 2018 in “Dermatologic Surgery” This study found that nonshaven follicular unit extraction is an effective method for pubic hair restoration in women with pubic atrichosis or hypotrichosis, based on high satisfaction scores from both patients and the surgeon.

,
September 1999 in “Journal of Investigative Dermatology” This study found that protease nexin-1 mRNA is expressed in human dermal papilla cells and is downregulated by dihydrotestosterone in balding scalp, suggesting a role in male-pattern baldness progression.
April 2018 in “Journal of Investigative Dermatology” This study suggests that macrophages play a more substantial role in the pathogenesis of Lichen planopilaris compared to Frontal fibrosing alopecia, as indicated by increased CD68+ cells in Lichen planopilaris.
January 2016 in “Springer eBooks” The document concludes that there are various causes and treatments for hair loss, with hair transplantation being a notable option.

February 2012 in “British Journal of Dermatology” This study suggests that the AR/EDA2R locus may contribute to early-onset female pattern hair loss, but no association was found with the 20p11 locus.
August 2016 in “Journal of Investigative Dermatology” This study observed that the osteopontin-derived peptide FOL-005 inhibited hair growth in human scalp skin models, contrary to its hair growth promotion in mice, supporting further clinical testing for excessive hair growth treatment.
