September 1997 in “PubMed” In this report, the authors suggest that for extensive baldness, the uniform density approach in hair restoration surgery is less noticeable, especially in situations like wind or exercise.
June 2025 in “British Journal of Dermatology” In this study, a daily low-dose regimen of oral minoxidil and finasteride over 12 months led to significant hair density improvements in over 92% of adult men with androgenetic alopecia, including those with advanced stages, though inter-rater reliability in photo assessments was modest.
June 2024 in “Indian Journal of Plastic Surgery/Indian journal of plastic surgery” This study found that using a specific ratio method based on the patient's scalp measurements can effectively predict the dimensions of the permanent safe zone for hair transplants, particularly in early stages of androgenetic alopecia, potentially ensuring long-lasting transplant results.
January 2020 in “International journal of scientific research” Dermoscopy shows that varying hair shaft thickness and single hair follicles are main signs of male pattern baldness, especially in the fronto-temporal region.
The robotic system for hair restoration surgery works well, giving similar results to manual techniques after 9 months.
January 2018 in “Georg Thieme Verlag eBooks” Hair transplantation is a surgical procedure to move hair to bald areas, requires good donor hair, and results show in about a year.
May 2014 in “Transfusion and Apheresis Science” PRP treatment showed no hair regrowth improvement after the first application in patients with alopecia.

January 2004 in “Journal of Clinical Dermatology” This study found that a high proportion of androgenetic alopecia patients were young individuals with mild types, potentially due to psychological stress in social situations.
March 2026 in “Frontiers in Medicine” This study suggests that traditional classification systems for pattern hair loss, while useful in the past, have limitations in accuracy and reproducibility, and highlights the potential of integrating digital imaging and AI to create more precise and biologically informed classification frameworks.

March 2019 in “Economic Inquiry” In this study, balding men reported an average willingness to pay around $30,000 to transition from complete baldness to having a full head of hair.
June 2026 in “Clinical and Experimental Dermatology” This review identified various outcome measure instruments for assessing androgenetic alopecia but found inconsistent application across clinical trials, underscoring the need for standardized assessment methods.
January 2025 in “International Journal of Trichology” This study found that patients with androgenetic alopecia had significantly higher COVID-19 severity compared to matched controls, suggesting a potential link between androgen pathways and disease severity. The authors suggest further research to validate this hypothesis and explore antiandrogen treatments for managing COVID-19 severity.
April 2023 in “Pakistan Journal of Medical and Health Sciences” This study found that sub-dermal platelet-rich plasma injections were effective for treating androgenic alopecia among both male and female participants.
This study found that platelet-rich plasma injections significantly increased hair count and improved hair loss in patients with androgenic alopecia, with high patient satisfaction and no notable adverse effects.
December 2022 in “Pakistan Armed Forces Medical Journal” This study suggests that a high frequency of androgenetic alopecia is associated with increased severity of COVID-19 in hospitalized patients.
December 2022 in “PubMed” This study observed that one-third of men with early-onset androgenetic alopecia had altered hormonal profiles, which were associated with increased insulin resistance and more severe hair loss.
December 2021 in “Biomarkers” This study found that men with early-onset male pattern alopecia did not significantly differ from healthy individuals in cardiovascular and metabolic measures, but hsCRP and galectin-3 were linked to cardiovascular risk factors in those with the condition.
This study compares datasets to analyze the prevalence of androgenetic alopecia in patients admitted with severe COVID-19 in three Madrid hospitals, focusing on age, gender, and alopecia severity.
This study reports that a majority of patients hospitalized with severe COVID-19 in three Madrid hospitals exhibited androgenetic alopecia, termed the "Gabrin Sign".
