Good nutrition is essential for healthy hair.

Sulphur in hair follicles increases from the bulb and then levels off, while other elements vary in distribution.

This study measured elemental content in anagen hair fibers of Caucasian people aged 10-69 and found average levels of sulfur, zinc, calcium, and chlorine, establishing a baseline for future research.

This article reviews a new method to accurately estimate proliferative and migratory epithelial cell numbers post-wounding but reports no experimental findings; the authors suggest its relevance to skin stem-cell biology research.

This study discusses using SEM/EDX for elemental analysis of hair samples in forensic science but notes challenges in detecting certain trace elements from raw hair.

Eating a balanced diet with enough protein, calories, trace elements, and vitamins is important for healthy hair.

This paper outlines the research plan and current progress of a study analyzing mineral metabolism changes in astronauts by examining hair shafts after long-term space flight, with no new results yet.

This study found that exposure to chlorine significantly reduced tensile properties in human hair compared to normal, while dyeing only affected some properties but not all.

This study found that WNT signaling is essential for the initiation of mammary gland morphogenesis in embryonic mice, promoting placode development and potentially playing a critical role in skin appendage formation.

This study found that activation or inhibition of Wnt/β-catenin and Notch signaling pathways in rats can alter wound healing, possibly by affecting epidermal stem cell activity and keratinocyte behavior.

In this study, anabolic and catatoxic steroids were reported to prevent weight loss, tissue calcification, and cardiac necrosis in a rat model of disturbed calcium metabolism and progeria-like syndrome.

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

In this study, zinc chloride was found to be severely irritant to the skin in rabbit, guinea-pig, and mouse models, while zinc oxide, zinc sulphate, zinc pyrithione, and zinc undecylenate showed minimal to no irritancy.

In this study, brindled mutant mice with clinical features similar to kinky hair syndrome showed marked improvement and prevention of neuronal degeneration after receiving cupric chloride injections, with timing of administration being crucial.

This study suggests that combining topical squaric acid dibutylester with other therapies may improve hair regrowth in patients with alopecia areata unresponsive to topical therapy alone.

Early diagnosis and treatment of TPP can prevent complications.

This study found that different decontamination protocols caused varying levels of cuticle damage in hair, with aqueous buffer treatment resulting in the most substantial degradation.

Chitosan/LiCl composite scaffolds help heal deep skin wounds better.

This study found that cupric chloride treatment may partially correct delayed maturation and abnormal arborization of Purkinje cells in the cerebellum of hemizygous brindled mice, a model for Kinky hair disease.

This study found that 5% primed conditioned medium from human umbilical cord blood-derived mesenchymal stromal cells significantly improved hair density, thickness, and growth rate in patients with androgenetic alopecia.

In this study, the researchers found that the absence of the NFI-C transcription factor delayed the hair growth cycle in mice by affecting key gene expressions and signaling pathways.

This study found that copper injections increased dopamine-β-hydroxylase activity in the brains of mottled mice, an animal model for Menkes' syndrome.

This article reviews the pathogenesis and treatment approaches for premature graying of hair, noting the unsatisfactory options currently available, and reports no new clinical findings.

This study found that hair absorbs significant amounts of NaBr from solution, with absorption increasing linearly with solution concentration and additional effects noted with acidic or basic solutions.

In this study, gamma/delta T cells were observed in skin after allergic or irritant reactions to heavy metal salts, suggesting a role in skin defense against these metals.

This study found that ovine dermal papilla cells exhibit robust aggregation in culture, offering a model to investigate the regulation of hair follicle dermal papilla size.

This study investigated a gelatin-based bioink for 3D bioprinting a simplified skin model, finding that a formulation with 15% gelatin and 150 mM calcium chloride supported a homogeneous distribution of viable cells over 14 days, showing promise for drug evaluation applications.

This study found that bulge-derived keratinocytes from human follicles were more resistant to differentiation compared to epidermal keratinocytes, possibly due to WIF-1 involvement.

This study found that porcine platelet-rich plasma can be a commercially viable replacement for fetal bovine serum with similar effectiveness in promoting human hair follicle cell growth.

This study reported that a liquid-liquid extraction method using methyl tert-butyl ether and methylene chloride was most effective for extracting dutasteride and its internal standard from rat plasma.
