The study improved understanding of keratin fiber structure by showing consistent microfibril diameter but varying distances and electron density profiles.

This article reviews androgenetic alopecia and its underlying mechanisms, highlighting genetic and androgen factors in its onset, and does not report new research results.

This study reports that trichocyte intermediate filaments from rat vibrissae and human hair follicles may contain a hollow region at their core, suggesting unique structural properties.

Healthy mitochondria in skin cells are essential for proper hair growth and skin cell interaction in mice.

In this study, women with polycystic ovary syndrome showed adverse lipoprotein profile changes that increase cardiovascular risk, which were found to be more closely related to androgen levels than body weight.

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 found that washing hair with surfactants reduces the internal density of hair due to cuticle lifting, and suggests that a cuticle-sealing strategy can inhibit this effect and maintain hair homeostasis.

This study found that Piezo2 channels are primarily located on sensory axon membranes in mechanosensory end organs, supporting a model where mechanical stimuli activate Aβ RA-LTMR neurons via axon protrusions.

This article outlines methods to study the skin and its molecular traits, focusing on interpretation and techniques applicable to mouse models, including diverse assays and approaches like electron microscopy and large-scale lipid analyses.

This study found that a low dose of flutamide, both alone and combined with an oral contraceptive, effectively reduced hirsutism in women, with the combination showing more lasting effects post-treatment.

This study found that modifying biphasic calcium phosphate/poly(methyl methacrylate) bone cement with human hair keratin improves its hydrophilicity, mechanical properties, and supports bone repair in rats, indicating potential for orthopedic applications.

This narrative review discusses the promising role of photobiomodulation in dermatology, emphasizing its non-invasive nature and potential benefits, but acknowledges the need for further research to establish standard protocols.

This article reports electron microscope studies on the structure of hair and wool, but it does not present new clinical findings.

This study analyzed watercress oil and confirmed its phytochemical profile, UV absorption properties, and potential efficacy for hair growth, supporting traditional hot oil applications.

The study found that a polymer treatment changes the charge on hair surfaces, making bleached hair smoother and less porous.

This study found that postmortem root banding in hair is likely due to the degradation of the intermacrofibrillar matrix in the cortex, with no damage to the cuticle observed.

In this study of a TRPS type I patient, many genes related to keratin and hair development were down-regulated in balding scalp areas, providing new insights into TRPS and hair morphogenesis.

SA linked to mitochondrial issues and oxidative stress, while AGA involves disrupted hair growth genes.

This study cataloged several long non-coding RNAs and microRNAs in cashmere goat dermal papilla cells, suggesting these non-coding RNAs may play a role in hair follicle stem cell activation and hair growth.

This study evaluated the effects of dry plantain leaf extract on mice infected with Plasmodium berghei, finding that the extract reduced liver oxidative stress associated with the infection.

This study found that Filipino patients with lupus typically develop myocarditis early and respond well to early immunosuppressive therapy.

This study highlights the challenges in treating Microsporum canis infections due to variable antifungal drug efficacy and potential resistance, emphasizing the need for standardized methods to assess drug susceptibility.

This study used proteomic profiling to reveal significant individual and site-specific differences in human hair shaft proteins, which may improve the differentiation of hair based on ethnic origin and individual identity.

This study found that finasteride treatment of male rats led to changes in their male offspring's testicular gene expression, potentially affecting sperm function in response to odorant-like signals.

This study found considerable variation in hair shaft proteomic profiles among Caucasian, African-American, Kenyan, and Korean subjects, with individual and site-specific differences observed.

This study found that in men with androgenetic alopecia, elevated triglycerides were the only factor consistently associated with the condition, suggesting a potential link between AGA and lipid metabolism, although other hormonal, metabolic, and sleep factors were not significantly different after propensity score matching.

This study found that the hairless gene in mice has a more extensive role in development than previously thought, as indicated by its expression in various tissues and associated abnormalities in hr/hr mutants.

This review suggests that standardized herbal shampoos may offer a safe and sustainable alternative to synthetic products due to their natural saponins and multifunctional benefits, though challenges in consistency and shelf-life persist.

This study observed that mice with a Cx43 mutation exhibited slower and asynchronous hair regrowth with severe cuticle weathering, mimicking aspects of hair phenotype in some ODDD patients.

This study found that N-acetyl-glucosamine-loaded nanostructured lipid carriers showed promise for skin lightening in healthy volunteers by reducing melanin distribution.
