This article discusses mouse genetic studies to explore factors influencing melanogenesis, highlighting pH and cysteine's roles, and proposes a hypothesis for human hair color diversity; it reports no new results.

This study used nanoscale secondary ion mass spectrometry to locate where calcium and copper are concentrated in colored hair, finding these metals particularly in the cuticle's sulfur-rich regions.

This study found that protein extracts from human hair demonstrated significant antioxidant abilities, protecting human dermal fibroblasts from oxidative stress, suggesting potential for biomedical applications.

This article discusses the roles of different proteins in melanogenesis and proposes a hypothesis to explain the diversity of human hair pigmentation, but it reports no new experimental results.

This article discusses the genetic hair disorder monilethrix, characterized by beaded, fragile hair due to defective keratin genes, and reports no effective treatment currently available; variability in severity was noted among affected siblings.

This study demonstrated that human hair keratins have strong antioxidative properties, providing protection against oxidative stress in human dermal fibroblasts, suggesting their potential as antioxidizing supplements.

This study observed that hair fibers in older women become more curved with age, decreasing hair luster due to their disordered alignment and structural differences between the convex and concave sides.

This study found that middle-aged patients, patients in certain geographical regions, and female patients of specific age groups with alopecia areata face higher medical costs, indicating significant financial variability for affected subgroups.

This study reported that keratin films lacking keratin-associated proteins showed different appearance, structure, and color deposit properties compared to conventional keratin films, suggesting potential for evaluating hair damage.

This study found that hair from ovarian teratomas shares similar chemical composition and morphology with scalp hair, but differs in physical properties and cysteic acid bands.

This article reviews the need for multicenter clinical trials to establish reference data for ultrasound screening protocols for Down syndrome and reports no new findings.

This study found that individuals with alopecia areata in Germany, Austria, and Switzerland face significant out-of-pocket costs averaging 1,248€ annually, primarily for hair replacement products and cosmetics.

This paper analyzes the representation of baldness in contemporary screen media, arguing that it reflects and perpetuates societal anxieties about masculinity, aging, and power, portraying hair loss as a disorder requiring intervention despite its natural occurrence and lack of health risks.

This case report describes a 35-year-old woman with a Rathke’s cleft cyst presenting with Cushing disease, highlighting the need to evaluate hormonal hypersecretion in atypical pituitary lesions.

This study found that a proteomics-based approach can effectively distinguish between scalp and pubic hair by identifying unique protein signatures, providing a more quantitative and objective method for tracing hair contamination sources in GMP manufacturing and forensic investigations.

This study reported that hydrogels created from keratins extracted from human hair exhibit antibacterial properties and enhance tissue regeneration, suggesting their potential use in full-thickness skin repair, as demonstrated by increased collagen production and improved healing in vivo.

This study found that a synthetic polyphenol, dimeric 1,2,4-benzenetriol (diBTO), can coat gray hair and gradually oxidize, creating a resistant brown layer similar to apple browning, which offers a practical hair dyeing solution that withstands washing and reduces the need for long dyeing sessions.

This study found that treating hair with ATS, formed from fumaric acid and cysteamine, effectively improved hair quality by increasing moisture content and altering the internal structure of strong curls.

This study suggests that human hair keratin-based gradient hydrogels incorporating silver ions may serve as promising dermal templates for wound healing, demonstrating favorable mechanical properties, cell interaction, and antibacterial activity.

This study found that reduced hair samples showed higher protease degradation than permed hair, which increased with repetitive perming, and degradation was influenced by the type of mercaptan used.

This study found that the structural and chemical composition of human curly hair may resemble that of sheep wool, implying a shared characteristic among mammals with wavy hair.

This report describes an unusual case of proliferating trichilemmal cyst with trichoepitheliomatous change in a young woman, differing from its typical presentation in elderly women.

In this study, L-methionine and L-serine application was observed to have the most significant effect on hair weight and root length, followed by acetyl L-methionine and L-serine, while glutathione inhibited growth.

This study found that N-acetyl-cysteine alone or combined with minoxidil improved hair parameters in men with early-onset androgenetic alopecia, with tolerable side effects.

This study describes two new types of dermal keratinous cysts of the eyelids, derived from the pilosebaceous apparatus, each presenting distinct management challenges.

This study found that immunohistochemistry for calretinin may identify certain cutaneous adnexal tumors with follicular differentiation towards cells of the outer root sheath.

This research studied European human hair, finding that cysteic acid and protein carbonylation increased with both chemical and photochemical oxidation. Protein carbonylation was highlighted as a more sensitive marker for photochemical oxidation, providing better in situ visualization of hair damage than cysteic acid.

This study identified a specific LIPH gene mutation (736T>A) as common in Japanese patients with autosomal recessive woolly hair/hypotrichosis, potentially indicating its role in the condition's manifestation within this population.

This study found that culturing hair follicles at the air-liquid interface enhanced hair growth and maintained an anagen-like morphology better than submerged cultures.

This study found that xylanase and pectinase enzymes clean wool and specialty hair fibers as effectively as soap, without causing physical damage, whereas resinase was not effective.
