This review discusses the processes of melanocyte stem cell quiescence and activation, focusing on their interaction with hair follicle stem cells, and highlights current research on hair graying mechanisms; it reports no new results.

In the phase 3 CAPItello-291 trial, capivasertib combined with fulvestrant significantly increased progression-free survival in patients with advanced breast cancer with specific genetic alterations, but the authors highlight that managing side effects like diarrhea, rash, and hyperglycemia is crucial for optimizing treatment adherence and outcomes.

This study found that cold exposure disrupts the circadian rhythm in cultured human cells by reducing oscillation amplitude, which is restored upon rewarming, while human hair follicle cells showed minimal amplitude sensitivity to temperature changes, suggesting an evolutionary advantage related to Hopf bifurcation dynamics.

In this study of women with breast cancer undergoing chemotherapy and scalp cooling, 12% experienced incomplete hair regrowth at 6 months, with tamoxifen therapy identified as a significant risk factor for persistent chemotherapy-induced alopecia.

This study found that engineered reconstituted skin can form morphogenetic units that promote tissue patterning and hair regeneration, with certain signaling pathways restoring this ability in adult and fetal cells.

This small study reports that a 6-group geometric classification method is more reliable for classifying human hair curl, although a digital system could further reduce errors.

This study found an increase in criminal and accidental thallium (Tl+) poisonings globally, particularly in Ukraine, partly due to online availability, underscoring the need for better control and diagnosis to prevent severe outcomes and potential misuse during ongoing conflicts.

This study found that keratin 15 expression is downregulated in hyperproliferative conditions like psoriasis and hypertrophic scars, suggesting it is not compatible with keratinocyte activation.

This study found that blue light at a wavelength of 453 nm promoted hair growth ex vivo, potentially through interacting with OPN3 receptors in human hair follicles.

This study found that women with androgenetic alopecia showed higher levels of certain hormones and lower levels of sex hormone-binding globulin than healthy controls, potentially linking these factors to alopecia severity.

In this study, encorafenib combined with binimetinib was well tolerated in melanoma patients, resulting in relatively few cutaneous adverse events compared to other BRAF and MEK inhibitors.

This study reports a new association of follicular mucinosis occurring in a patient with Sézary syndrome.

This study assessed breeding value estimation methods for Korean Sapsaree dogs, finding varied accuracy across BLUP approaches and identifying significant genomic regions affecting traits like body height and hair length. The researchers suggest these findings can enhance breeding strategies for this culturally significant breed.

This review discusses management strategies for androgenic alopecia using plant derivatives and highlights the need for prolonged efficacy but reports no new clinical findings.

This case study reports a pregnant woman with bullous pemphigoid who developed Cushing syndrome following steroid treatment, emphasizing the need for careful management of steroid-related complications.

This review examines the effects of various factors on the molecular and nanostructural ordering of human hair, highlighting its potential as a diagnostic material for environmental and public health monitoring, but reports no new experimental results.

This research review highlights how hair cortisol concentration can reflect the activation of the stress-response system in farm, domestic, and wild animals, noting it correlates with factors like species, sex, age, and environmental conditions, which may influence stress and adaptation.

This literature review outlines the traditional uses, nutritional composition, and bioactive compounds of pomegranate plants, highlighting their varied pharmacological actions such as antibacterial, antiviral, anticancer, and antioxidant effects, and discusses the peel's chemical composition and toxicology.

This study identified the safest groups of shampoos based on their harmful components, price, and consumer assessments, recommending specific options for health-conscious consumers.

This review summarizes the volatile components, biological activities, and potential safety concerns of essential oils from various Curcuma species, but reports no new clinical results.

This study observed no significant difference in vitamin D levels between children with alopecia areata and controls, but higher complete improvement in alopecia was noted among patients with vitamin D deficiency undergoing oral vitamin D treatment.

This study found that platelet-rich plasma therapy significantly improved hair density, diameter, and reduced inflammation in androgenetic alopecia patients compared to placebo, though individual responses varied.

In this study, researchers used a 3D printing technique to spatially pattern human dermal papilla cell spheroids in a collagen matrix, enhancing skin and hair regeneration in a mouse model, with notable upregulation of key genes for hair follicle formation compared to traditional cell cultures.

This study found that Sonic Hedgehog secreted by hair follicle transit-amplifying cells is essential for dermal adipogenesis and hair follicle growth by acting on adipocyte precursors.

This review examines around 68 plant sources from six major plant families, assessing their scientific rationale and use by the cosmeceutical industry for applications like anti-ageing and sun protection.

This study found that exposure to certain elements during pregnancy, measured in maternal hair, was associated with increased risk of gestational diabetes and potential impacts on infant neurodevelopment, with elements like Ta, Re, and Se posing the highest risk for gestational diabetes.

This study suggests that prenatal exposure to THC may negatively impact ovarian health in rats by altering miRNA expression, potentially leading to reproductive issues such as subfertility or premature reproductive senescence.

This study reported that the incidence of telogen effluvium nearly tripled during the pandemic, with significant increases in Hispanic and non-White populations, and suggested comorbidities combined with COVID-19 positivity may raise the risk.

This review highlights recent insights into using antiandrogens as preventive and therapeutic measures against COVID-19, emphasizing their role in blocking viral infection by modulating androgen-mediated host protease TMPRSS2 and cell entry protein ACE2, with varying success in clinical trials.

This study reviews various skin models and methodologies used to assess the follicular penetration of nanoparticle-based drugs, highlighting inconsistencies that complicate comparisons and aims to establish more uniform protocols for clearer study outcomes.
