This study suggests that cortisol measured in human hair can effectively reflect increased production for up to six months, but its retrospective accuracy may be limited due to rapid decline in levels.

This article reviews the mechanisms by which minoxidil stimulates hair growth and reports no new clinical findings.

This article discusses the treatment of androgenetic alopecia and alopecia areata with finasteride and minoxidil but reports no new clinical results.

This review discusses the potential impact of endocrine-disrupting chemicals and body size on pubertal onset and progression, highlighting critical gaps and priorities for future research without presenting new clinical results.

In this study, finasteride 1 mg/day for 12 months did not improve hair growth or slow hair thinning in postmenopausal women with androgenetic alopecia compared to placebo.

This review explores possible reasons for why male COVID-19 patients experience more severe symptoms and higher fatality rates than female patients but provides no new clinical results.

In this study, androgen did not affect keratinocyte growth in coculture with androgenetic alopecia-derived dermal papilla cells, but did significantly suppress keratinocyte growth when androgen receptor was overexpressed in the papilla cells.

This article reviews the pathogenesis, genetic basis, and recent treatment breakthroughs for androgenetic alopecia but reports no new clinical findings.

This study found that finasteride improves scalp hair growth in men with male pattern hair loss by reducing scalp dihydrotestosterone levels, but it did not benefit postmenopausal women with female pattern hair loss.

This literature study reviews the consequences of hair loss due to chemotherapy and nursing care interventions but reports no new clinical results.

This review examines recent advances in understanding the pathophysiology and molecular mechanisms of androgenetic alopecia, highlighting two major genetic risk loci, but does not report new clinical findings.

This study found that a new 5% minoxidil foam formulation significantly increased hair counts and improved hair loss condition in men with androgenetic alopecia over 16 weeks compared to placebo.

Inflammation may be linked to hair loss, and targeting specific enzymes could help treat it.

This review discusses the hyperfunction theory of aging as a key factor in COVID-19 vulnerability, highlighting the potential of anti-aging interventions like rapamycin to reduce this risk.

This study found that increased expression of type II 5α-reductase, androgen receptors, and Hic-5/ARA55 in dermal papilla cells upregulates androgen sensitivity, playing a key role in androgenetic alopecia pathogenesis.

This study suggests that finasteride's effect on promoting hair growth in men with androgenetic alopecia may be due to its inhibition of 5aR2 localized in hair follicles.

This study found that combining oral finasteride with topical minoxidil resulted in the greatest improvement in hair growth for male patients with androgenetic alopecia, compared to using any single treatment.

This study found that procyanidin oligomers, particularly dimers and trimers, significantly promoted hair growth in mice and hair epithelial cell cultures, suggesting potential use as hair growth agents.

This study found that the progestins norgestimate and dienogest may help treat clinical hyperandrogeny in women by inhibiting skin 5 alpha-reductase activity with minimal androgenic potential.

This review discusses the dermatologic features of PCOS as potential early indicators of the syndrome and notes that treatment of these conditions may enhance quality of life and psychological well-being, but it reports no new clinical results.

This study observed that Japanese women experience diffuse central hair loss after age 40, characterized by reduced hair density and thicker hair ratio rather than vellus-like hairs.

This study found that prostaglandin metabolism enzymes are present in human hair follicles, suggesting a potential role in hair growth and differentiation, with some expression differences between men and women.

This review discusses recent advances in using nanocarrier-loaded gels for various medical applications and reports no new clinical results, highlighting potential advantages in therapeutic strategies.

This article reviews common hair growth abnormalities in children, emphasizing the importance of distinguishing normal development from potential signs of metabolic disorders and indicates no new clinical results.

This speculative review discusses hair cycle-dependent fibroblast dynamics and possible impacts on human hair growth, synthesizing current literature without presenting new clinical findings.

This study demonstrates that patients with benign prostatic hyperplasia have a higher severity and frequency of male pattern baldness compared to a control group.

This study observed that finasteride and spironolactone both led to a similar significant, but limited, improvement in hirsutism despite their differing effects on androgen levels.

This review discusses updated treatment guidelines for alopecia areata in Japan, highlighting new options like corticosteroid pulse therapy, but reports no new clinical results.

This study found that twice-daily application of 3% topical minoxidil maintained a higher nonvellus hair count compared to once-daily application over 2 years and 9 months in men with male pattern baldness.

This review discusses advancements in the use of microneedle arrays and nanoparticles for transdermal delivery of therapeutics, noting challenges in overcoming the skin barrier and summarizing recent clinical trial achievements in areas like cancer therapy and gene therapy.
