April 2022 in “Sleep and Breathing” This study found an association between sleep disturbances and androgenetic alopecia in men, with severe AGA linked to shorter sleep duration, poorer sleep quality, and higher STOP-BANG scores.
15 citations
,
July 2021 in “JAMA Dermatology” This study found that androgenetic alopecia is significantly associated with moderate impairment of health-related quality of life and emotions, but not with depressive symptoms.
77 citations
,
March 2021 in “Nature” In this study, increased corticosterone from chronic stress prolonged hair follicle stem cell quiescence in mice, inhibiting regeneration, but restoring Gas6 expression overcame this inhibition.
6 citations
,
March 2020 in “Journal of International Medical Research” This study reported that early-onset androgenetic alopecia primarily affects Chinese males aged 21–30, with a high likelihood of paternal inheritance.
4 citations
,
February 2020 in “Dermatologic Therapy” Poor sleep, meat-heavy diets, and junk food worsen hair loss, while sugary drinks may help.
8 citations
,
August 2019 in “Journal of The American Academy of Dermatology” This study found that androgenetic alopecia is a significant yet under-recognized cause of hair loss in children and adolescents, often linked to family history and typically diagnosed by clinical examination.
12 citations
,
January 2019 in “Sleep medicine” This study found that night shift work disrupts clock gene expression in Japanese men, particularly affecting rhythms and levels of Period3 and Nr1d2, based on the shift schedule.
5 citations
,
August 2018 in “International Journal of Dermatology” This study suggests obstructive sleep apnea may increase the risk of male-pattern baldness in men with a family history of hair loss, and links low serum transferrin saturation levels to both conditions.
9 citations
,
July 2018 in “European journal of dermatology/EJD. European journal of dermatology” This study provides evidence that long-term deregulation of the circadian rhythm in humans affects the regenerative properties of skin and hair precursor cells by altering clock pathway protein expression.
49 citations
,
April 2016 in “International journal of molecular sciences” This study found that shift nurses exhibited lower circadian variations compared to daytime nurses, indicating an adjustment of their biological clocks to continuous shift schedules.
33 citations
,
August 2015 in “F1000Research” This study presents a new model for androgenetic alopecia progression, explaining diffuse hair loss in women through 3D reconstructions of the arrector pili muscle and its relationship with the hair follicle stem cell niche.
14 citations
,
March 2014 in “Journal of The European Academy of Dermatology and Venereology” This study found that androgenetic alopecia in asymptomatic young men was associated with increased arterial stiffness, as measured by the cardio-ankle vascular index.
92 citations
,
September 2013 in “Journal of Investigative Dermatology” This study found that peripheral clock genes, particularly BMAL1 and Period1, modulate human hair follicle cycling, suggesting their potential as therapeutic targets for affecting hair growth.
9 citations
,
August 2013 in “Archives of Dermatological Research” This study concluded that the expression of clock genes, specifically BMAL1, in hair follicles is linked to circadian rhythm, and BMAL1 regulates hair growth.
116 citations
,
May 2013 in “Proceedings of the National Academy of Sciences of the United States of America” This study discovered that the circadian clock influences hair follicle regeneration, making hair grow faster in the morning and causing more radiation-induced hair loss in the morning compared to the evening.
38 citations
,
August 2012 in “Biochemical and biophysical research communications” This study found that leukocytes and beard hair follicle cells have an endogenous circadian clock, with PER1 and PER3 expression possibly serving as biomarkers for assessing individual biological clock traits.
166 citations
,
August 2010 in “Proceedings of the National Academy of Sciences of the United States of America” This study reports a less invasive method for detecting human clock gene expression using hair follicle cells, which accurately reflects individual behavioral rhythms and suggests a time lag issue for rotating shift workers.
50 citations
,
December 2008 in “Clinical Endocrinology” This study found that young males with stage III or higher androgenetic alopecia had higher insulin resistance and cardiovascular-related features, suggesting the need for metabolic assessment in this population.
