This study found that tight junctions extend to the most superficial layer of the stratum granulosum in human skin, challenging previous claims of their limited presence in the epidermis.

This study found that the desmosomal protein desmoplakin is crucial for proper epidermal morphogenesis and radial intercalation in developing Xenopus embryos, affecting keratin organization and ectodermal structures.

This study found that age-related changes in scalp dermal fibroblasts, including increased MMP-1 and reduced ECM components, may significantly affect the hair follicle environment and contribute to hair aging.

This study describes a new method for isolating intact human eccrine glands from scalp follicular units, potentially advancing research on sweat gland physiology.

This study suggests that GATA6 is a key regulator of the upper pilo-sebaceous unit homeostasis and differentiation in human skin.

This study explored how root hairs integrate opposing growth signals but did not report new conclusive findings on the activation of known molecular players in polar growth.

This review discusses biotin's role in nutrition and suggests no benefit to supplementing it for hair, nails, and skin in healthy individuals; it reports preliminary findings that high dosages may help some multiple sclerosis patients.

Diuretics help the body get rid of excess salt and water by acting on the kidneys in different ways.

AGA is a common hair loss disorder, and early diagnosis and treatment with minoxidil or finasteride can help reduce emotional distress.

This review explores the biology of wool follicles and suggests their potential use as research models in modern biology, but it reports no new findings.

This article discusses the widespread issue of zinc deficiency affecting plant, animal, and human health, and reports no new clinical results; the authors emphasize the need for adequate zinc availability in agriculture and nutrition.

This study found that reduced cytokinin levels allow plants to adapt to low potassium conditions by enhancing root hair growth, reactive oxygen species accumulation, and expression of a key potassium transporter gene.

This review discusses zinc's role as an essential trace element in human nutrition, particularly its importance in total parenteral nutrition, and reports no new clinical results.

This study found that antibiotic-induced gut dysbiosis, particularly overgrowth of Lactobacillus murinus, can lead to hair loss in mice by depleting biotin.

This review found that patients with alopecia areata may have lower levels of vitamin D, zinc, and folate, but conflicting evidence precludes definitive clinical recommendations for micronutrient supplementation.

This study found that the PLC2 gene plays a critical role in auxin-mediated root development in Arabidopsis, influencing root growth and PIN2 distribution.

This article discusses the potential relationship between androgenic alopecia and insulin resistance but presents no new clinical findings, calling for further research on the topic.

This review discusses the role of PIN-FORMED 2 and related signaling pathways in root hair growth regulation and reports no new experimental findings.

This review discusses the molecular mechanisms of androgen action in human hair follicles and reports no new findings; the authors emphasize the need for further research to improve treatments for hair disorders.

This review discusses the role of biotin in metabolism and the consequences of its deficiency, reporting no new clinical results.

This chapter reviews signaling pathways related to androgenic alopecia in dermal papilla cells of balding human scalps, integrating published information and analysis of molecular interactions, without reporting new clinical results.

Certain micronutrients may improve hair and nail health, but more research is needed to confirm their benefits.

This study found that Limelight (CB-EVs) exosomes significantly promoted hair elongation ex vivo without cytotoxicity, suggesting potential as a safe and effective hair growth therapy.

This study investigates the complex impact of bariatric surgery on skin disorders, reporting improvements in conditions like acanthosis nigricans and psoriasis, while new issues such as xeroderma and alopecia may also emerge postoperatively.

This study found that soups with 5% and 10% hibiscus flower were more desirable in sensory attributes and had higher β-carotene content compared to the control soup.

This study reports that a low concentration of chitosan induces callose deposition and slows root hair growth in Arabidopsis, suggesting an evolutionary conservation of this response to mild biotic stress across plant types.

This study found that among university students, both low and high zinc levels were associated with significant hair loss, while these zinc concentrations did not significantly impact other health issues like diarrhea, acne, or weight loss.

The study suggests that variability in platelet-derived growth factors in PRP is influenced by both patient-to-patient differences and the devices used for PRP preparation, contributing to inconsistent clinical outcomes in hair loss treatments.

In this study, biotin supplementation was found to significantly increase wool follicle viability and metabolic activity in vitro, with the highest effects observed at 0.5 mg L⁻¹ concentration.

This review discusses the use of Dermal Papilla cells as in vitro models for studying hair growth modulators, emphasizing their role in aiding the development of new hair treatments, but reports no new clinical results.
