This case report identifies a new type of hair matrix tumor called "rippled pattern trichomatricoma," distinguished by its unique cell arrangement and differentiation features.

This study found that dermal papilla cells from balding scalp follicles secrete significantly less insulin-like growth factor-1 and its binding proteins, suggesting a mechanism contributing to male pattern baldness.

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.

This study found that older men with vertex balding had lower levels of IGFBP-3 and higher levels of IGF-1 in their plasma.

This review discusses the impact of COVID-19 on the endocrine system and reports no clinical results; the authors emphasize the need to investigate endocrine damage during and after COVID-19 infection.

This article discusses concerns and recommendations from a French-speaking andrology society regarding COVID-19's potential impact on men's reproductive health and calls for further research in this area.

In this study, minoxidil significantly downregulated interleukin-1 alpha expression in human keratinocyte cells, suggesting an anti-inflammatory effect that may be a mechanism of action in treating alopecia.

This study found that 5α–reductase activity is higher in infrainfundibular keratinocytes compared to interfollicular epidermal keratinocytes, suggesting a potential role in acne-related follicular changes.

MK-386 and finasteride together effectively reduce DHT levels, potentially treating acne and male pattern baldness.

This study observed that GREM2 was specifically and robustly expressed in the dermal sheath cup of hair follicles during various hair cycle phases, suggesting its significant role in regulating hair cycling processes through BMP signaling.

This study found that male COVID-19 patients with androgenic alopecia at a Peruvian hospital were more likely to experience moderate to severe symptoms compared to those without alopecia.

This review critiques a study on androgenetic alopecia in hospitalized COVID-19 patients, highlighting analytical inaccuracies and suggesting that the condition's prevalence may relate to older age rather than COVID-19 infection.

This study evaluated the Spanish version of the Hair Specific Skindex-29 questionnaire and found it sensitive to changes in health-related quality of life among women with female-pattern hair loss.

This study found that older men with vertex balding have lower circulating levels of the protein IGFBP-3 and higher levels of IGF-1.

This study describes a case of a 35-year-old woman who developed symptoms of hyperandrogenism and disrupted steroidogenesis due to chronic use of electronic cigarettes containing compounds similar to etomidate, despite no genetic mutation indicating 11β-hydroxylase deficiency.

In this study conducted in the Makkah region, researchers observed that hair loss, mostly telogen effluvium, is a prevalent post-COVID-19 symptom, particularly among women and those with multiple health issues.

This report describes a case of a woman with ophiasis-pattern alopecia areata who experienced significant hair regrowth and maintained it for 6 months after treatment with dupilumab, though she eventually relapsed.

This research discusses androgenic alopecia's potential role in severe COVID-19 symptomatology and suggests further exploration of the scalp's role in virus transmission.

This letter discusses existing research and encourages further studies on the relationship between androgenetic alopecia and COVID-19 severity, reporting no new clinical results.

This commentary discusses how common latent viruses might contribute to male-pattern baldness through mechanisms involving transcription factor deficiency and overexpression of specific proteins, based on a concept called microcompetition; it reports no new research results.

This report describes an elderly woman whose nonclassic 11-hydroxylase deficiency, presenting as acne and male pattern alopecia, may have been ameliorated by Ashwagandha root in a dose-related manner.

This study found that the Spanish version of the hair-specific Skindex-29 questionnaire effectively detected changes in health-related quality of life among women with female-pattern hair loss, and the scores were significantly correlated with the SF-12 survey results after treatment with a 5 alpha-reductase inhibitor.

Finasteride 1 mg effectively treats male pattern hair loss with minimal side effects.

This study discovered that the disposition of LY191704 enantiomers in rats and dogs is both stereoselective and species specific.

This study found that women with female pattern hair loss had significantly lower serum IGF-1 levels than controls, suggesting a possible role for IGF-1 in this condition.

This study found that women with female pattern hair loss had significantly lower serum IGF-1 levels compared to controls, but no significant association between IGFBP-3 levels and hair loss severity was observed.

This study found that prolonged use of finasteride and dutasteride in young men with androgenic alopecia is linked to a decline in semen quality over time, particularly affecting sperm motility and DNA integrity, with dutasteride showing a slightly greater impact than finasteride.

In this case-control study, researchers observed that women with female pattern hair loss exhibited significantly lower serum IGF-1 levels than controls, while IGFBP-3 levels showed no significant difference, suggesting a potential role for IGF-1 in the condition.

This study found that hypoxia-conditioned mesenchymal stem cell exosomes increased GM-CSF and decreased IL-1 expression in a dose-dependent manner in a murine model, suggesting potential for treating androgenetic alopecia.

This study explores a novel hypothesis for Male Pattern Baldness, suggesting that chronic tension in the scalp's Galea Aponeurotica creates a hypoxic environment affecting hair follicles, and proposes a Triad Therapeutic Protocol to address this underlying cause rather than just the symptoms.
