Polarizing light microscopy can easily and reliably diagnose congenital keratinizing disorders like Netherton syndrome.

Scurvy, caused by vitamin C deficiency, can occur in people with restrictive diets and can be diagnosed by twisted hair shafts.

In this study, researchers found that the gene Dkk4 influences color pattern formation in domestic cat fetuses, and its mutation is linked to the Ticked pattern type.

This study observed that K5Cre +/+ transgenic mice develop a distinct phenotype characterized by wavy hair, curly whiskers, and an increased rate of papilloma malignant transformation.

This study found that supplementing pregnant and lactating mice with high dietary copper improved survival and physical traits in mice carrying the crinkled mutation, suggesting copper's role in modulating gene expression.

This report presents a unique case where a man developed Beau's lines on all fingers of one hand after a thumb injury, with the lines eventually disappearing as the nails grew.

This study explored the role of Twist2 in fetal wound healing in embryonic mice, observing that its expression was vital for scarless regeneration and normal hair follicle formation; Twist2 knockdown led to visible scars and defective follicle formation.

This study introduces a tabletop technique demonstrating that endogenous biomagnetic fields from human hair can induce red blood cells agglutination and Rouleaux formations.

Adding keratin to a mix of cow hair and plant-based plastic makes it stronger.

This study demonstrated that a metric based on rotational echo intensity in 2H magic-angle spinning NMR can derive kinetic information for conformational exchange without complex modelling, achieving activation barriers consistent with prior findings.

This study demonstrated that the Turing bifurcation, typically a pitchfork bifurcation under zero-flux conditions, becomes transcritical under fixed boundary conditions, highlighting the importance of considering boundary condition variations in morphogenetic analyses.

This report describes four cases of monilethrix in children and concludes that periodic inhibition of keratin synthesis, not a metabolic defect, may explain the hair abnormality.

In this study, using tyrosine as a cross-linking agent for hair perming showed better initial results compared to commercial products, though efficiency decreased after washing without compromising hair strength.

This study on feather pattern formation in chicken skin found that inhibiting gap junctional intercellular communication can lead to the emergence of new feather buds in specific spatial patterns, suggesting that GJIC may facilitate Turing-type periodic patterning by propagating inhibitory signals over long distances.

This study found that hair care products designed for coily/curly hair are significantly more expensive than those for straight hair, based on pricing data from Amazon.com. This indicates a need for equitable pricing to ensure access to affordable hair care for all hair types.

This mini-review highlights emerging themes on how tissue stiffness, a fundamental material property, influences morphogenetic processes in living organisms, an area gaining increased attention alongside the role of mechanical forces in shaping cell behavior.

In this study, treatment with recombinant DKK2 was shown to significantly stimulate hair progenitor cell growth and enhance hair shaft elongation in ex vivo human hair follicle cultures by activating the Wnt/ẞ-catenin signaling pathway, suggesting a potential role for DKK2 in promoting hair growth.

This study found that treating hair with 1 M sodium hydroxide increases its self-friction coefficient, suggesting potential applications in forming fine frictional fibers for medical uses.

This study found that BBS7 is important for Sonic hedgehog signaling activity, which may be crucial for maintaining periodontal ligament homeostasis in occlusal hypofunction.

In this study, transgenic mice expressing a mutant K6 gene developed progressive scarring alopecia and keratosis, suggesting they may model a new keratin disorder.

This review discusses Toe Tourniquet Syndrome, a frequently misdiagnosed condition that can lead to necrosis if untreated, and calls for increased clinician awareness, but reports no new clinical findings.

This study suggests that the harlequin ichthyosis mouse model closely resembles human type 2 harlequin ichthyosis, indicating its potential as a useful model for studying the human condition.

In this study, researchers identified specific gene polymorphisms in Subo Merino sheep that significantly affect wool traits, suggesting these genetic markers could aid in breeding high-quality fine-wool sheep.

This review discusses the management of recurrent ischemic priapism, highlighting that various treatments show differing efficacy and side effect profiles but that more research is needed to refine these strategies.

A 7-year-old girl was diagnosed with Netherton's Syndrome, shown by skin and hair symptoms.

This study found that human hair keratin bridges effectively induced nerve regeneration and demonstrated good biocompatibility and controlled degradation when used in rats with peripheral nerve defects.

Tight hairstyles can cause hair loss, which can be permanent if not treated early.

Using silicon circular iron on Korean women's hair increases hair thickness the most.
