This review discusses past research on the chemical and physical properties of human hair, focusing on structural analysis and mechanical property measurements with methods like SEM and tension tests, but adds no new findings.

This study found that women with alopecia have significantly lower tensile strength in both dry and wet hair samples compared to controls, indicating increased hair breakability.

This study found that dental students' manual dexterity was weakly associated with their performance in skills-based assessments, while self-perceived skill levels showed no significant correlation with assessment outcomes, suggesting a potential benefit from focusing on dexterity enhancement in dental education.

Hair diameter diversity is a key sign for diagnosing and managing male pattern baldness.

This study identified a new FAK isoform, FAKΔe4, which is regulated by ECM stiffness and affects cell migration, invasion, and mechanosensing in human-derived data and engineered models.

This study reports the first detection of electromagnetic forces from human hairs, evidenced by the aggregation of iron nanoparticles around hair follicles.

This study developed and validated a mass spectrometric method to measure hydroxy-androgens in serum, which aids in understanding androgen synthesis in castration resistant prostate cancer.

This paper examines factors affecting the stretching setting treatment of human hair and wool, concluding that the intended outcomes can be achieved using their customized testing equipment and technology.

This case study describes a 31-year-old man with myotonia and a history of hypertrophic cardiomyopathy and androgenic alopecia, who presented with arm and leg weakness.

Finasteride, a drug that changes testosterone to a different hormone, was studied and its effects over time were modeled successfully.

This review discusses recent progress in PENG-based sensors for non-invasive medical diagnosis and treatment but reports no new experimental results.

This review discusses molecular dynamics studies of hair keratin, highlighting newly developed computational models that replicate experimental phenomena and offering insights into molecular mechanisms.

This study developed a digital tool for quantitatively assessing hair in androgenetic alopecia, achieving an average accuracy of 79.45% for counting hairs and 68.19% for measuring hair size compared to human evaluation.

This study developed a new method using liquid chromatography-tandem mass spectrometry to measure multiple steroid hormones in hair, requiring significantly fewer strands than previous methods, with high accuracy and precision.

In this study, researchers characterized a dehydroepiandrosterone hydroxylating enzyme system in hair follicles similar to the liver monooxygenase system, noting its inhibition by carbon monoxide and its dependence on NADPH.

In this pilot study, the Rapid Fire Hair Implanter Carousel facilitated graft placement in hair transplantation by reducing bleeding and operative time compared to the traditional manual method.

This study presents a method for extracting and measuring cyclic AMP in small amounts of skin tissue, finding varying levels in the dermis, epidermis, and hair follicles.

This review found that 5α‐reductase inhibitors were associated with slightly increased rates of decreased libido, erectile and ejaculatory dysfunction, gynecomastia, and mood disorders compared to placebo, though their long-term effects remain unclear.

This study demonstrated that testosterone treatment increases muscle strength and alters body composition in transmen, and the addition of dutasteride does not impair these anabolic effects.

This study reports that pulsed biomagnetic fields may play a role in the deformation of red blood cells by facilitating cross-talk between RBCs and human hairs in vitro.

This research investigated how moisture absorption impacts human hair structure, finding that moisture sorption kinetics reveal insights into chain entanglement and structural changes due to cosmetic treatments, while also quantifying the influence of sample weight and fiber density on the sorption process.

Molecular dynamics simulations help understand keratin's properties and predict hair's response to treatments.

This study found that treatments like abrasion, bleaching, and CETAB application affect hair fiber shear modulus differently, with moisture levels notably impacting bleached fibers more than untreated ones.

This review discusses the importance of physical examinations in trichology, emphasizing their role in diagnosing conditions like alopecia and hair dystrophies, and reports no new clinical results.

In this study, researchers found that progesterone promotes breast tumor growth in mice through its metabolite 5αP, which can be blocked by the 5α-reductase inhibitor finasteride.

This study found that structural changes in the stroma surrounding hair follicles and skin laxity are associated with the appearance of large pores, regardless of ethnicity or age.

This study found that combining electrical stimulation with minoxidil had a synergistic effect on the proliferation of cultured human dermal papilla cells, potentially through enhanced activation of the Wnt/β-catenin pathway.

This pilot study by Samuel Jellard et al. investigated a novel electrotrichogenic device for hair growth in men with androgenetic alopecia. Results of the study are not reported, as the abstract only references the article's focus.
