This article presents a classification system for stages of female-pattern androgenetic alopecia to aid early diagnosis and mentions existing systems for rare male-pattern cases, but reports no new clinical results.

In this study, platelet plasma growth factors from patients' autologous plasma improved follicular unit yield in baldness surgery by 15.1% compared to control areas.

This study found that androgenetic alopecia may involve a defect in the conversion of hair follicle stem cells to progenitor cells, as demonstrated by a reduced presence of progenitor cells in bald scalp samples.

This study found that dermal papilla cells from balding scalp hair follicles have significantly higher levels of androgen receptors than those from non-balding follicles, supporting their in vivo androgen response.

This study presents evidence suggesting that androgenetic alopecia is most likely inherited through a polygenic model, challenging the traditional view that it is caused by a simple Mendelian autosomal dominant gene.

The researchers reported that DHT-inducible DKK-1 may play a significant role in DHT-driven balding by inhibiting hair follicle cell growth and promoting apoptosis in androgenetic alopecia.

Minoxidil increases blood flow in balding scalps, possibly reversing hair loss.

In this study, researchers used genetic data from over 52,000 men to identify over 250 genetic loci associated with severe hair loss and developed a predictive algorithm for determining hair loss risk.

This study found that men with common male pattern baldness received less favorable initial social perceptions, including lower ratings of physical attractiveness, than their nonbalding counterparts.

This study identified 63 genetic loci associated with male-pattern baldness, uncovering genes and pathways that may help develop treatments and suggesting its connection to other human conditions.

In this study, researchers found that while the SNP rs6152 is strongly associated with androgenetic alopecia, the GGN triplet repeat is not, suggesting the causative variant is likely a non-coding one.

This study found that male pattern baldness in European males is strongly heritable and associated with genetic markers linked to earlier puberty, bone density, and pancreatic function.

This genome-wide association study identified 71 genetic loci linked to male pattern baldness, with 30 novel loci, explaining 38% of the risk and suggesting shared pathways with lifespan and cancer traits.

This abstract does not provide specific findings or results.

This study suggests a potential link between early-onset baldness before age 30 and increased risk for coronary artery disease, warranting consideration in epidemiological research.

This study found that a genetic test using 5 to 20 SNPs can predict male pattern baldness with variable accuracy in European men, especially those aged 50 and older.

This study suggests that down-regulation of vasculature-related genes in dermal papilla cells from balding scalps might contribute to the development of androgenetic alopecia.

This study found that a genetic model using SNPs can predict early-onset male-pattern baldness with moderate accuracy, which may assist in decisions about interventions.

Testosterone was found to inhibit hair follicle epithelial cell proliferation in adult stumptailed macaques only when dermal papilla cells from bald scalps were present, and this effect was reversed by the antiandrogen RU 58841.

This study found that male pattern baldness and a history of severe acne were inversely associated with testicular germ cell tumors, while taller height showed a positive association.

This study found that scalp injection of fat enriched with stem cells may offer a promising alternative for treating early genetic alopecia in both men and women.

This study found no difference in male pattern baldness between patients with benign prostate hyperplasia and prostate cancer, and no correlation with serum androgen levels.

This study found that negative social attractiveness ratings for bald men by same-aged women occurred only when individuating information about the target was absent, while the physical attractiveness stereotype remained active at an implicit level.

This study suggests a possible link between late puberty onset and decreased prostate cancer risk, while over-the-counter ibuprofen use was associated with increased risk.

In this study, researchers found that severe androgenic alopecia in hospitalized men was associated with a higher likelihood of testing positive for COVID-19.

This study found that early-onset male pattern baldness was associated with a reduced relative risk of prostate cancer.

This study observed that frontal plus moderate vertex baldness at age 45 was associated with a higher risk of aggressive prostate cancer in a large cohort.

Baldness treatments focus on improving appearance and have psychological impacts.

In this study, 53% of patients with male pattern baldness experienced significant hair growth with one year of topical minoxidil, while 95% rated its effectiveness as moderate or excellent.

This study reported that human balding scalp grafted onto nude mice showed reduced linear growth rates of both vellus and terminal hairs.
