This article reviews historical reports of skin changes, such as pseudoacanthosis nigricans, associated with cholesterol-lowering drugs like triparanol and nicotinic acid, but presents no new clinical findings.

In this study, researchers suggest that hair follicle miniaturization in conditions like androgenetic alopecia may result from impaired conversion of quiescent stem cells to progenitor cells, influenced by the follicular niche, its collagen network, and various mechanical constraints.

This research review observed that topical hormone replacement therapy, particularly estradiol and estradiol-testosterone combinations, significantly increased Type I and III collagen synthesis in the skin of postmenopausal women, suggesting benefits against collagen loss-related skin aging effects such as reduced elasticity and increased dryness.

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 article integrates existing literature on hair follicle structure and formation at the cellular and molecular level, reporting no new findings.

This study introduced a bioengineering platform that creates early-stage hair peg-like structures within tissue-engineered skin substitutes by integrating human keratinocytes and dermal papilla cells with laser-micropatterned collagen scaffolds, providing a foundation for future appendage-inclusive skin regeneration efforts.

This study found that using a microfiber towel to dry human hair better preserves hair keratin integrity and wear resistance compared to blow-drying or using a cotton towel, as indicated by stronger alpha-helix structure in FTIR analysis.

Collagen XVIII is crucial for maintaining tissue structure and function in the brain, kidneys, and hair.

This study found that adding dithiodiglycolic acid to the hair straightening process decreased chemical damage and preserved the structural integrity of the hair matrix compared to using thioglycolic acid alone.

This chapter defines skin integrity as a blend of intact structural elements and adaptable functional capacity, highlighting its importance in maintaining skin health across various conditions but reports no new research findings.

This review discusses the development and role of corneodesmosin in skin and hair follicle integrity, highlighting findings from mouse models and its connection to genetic diseases, with no new experimental results included.

This study found that Rac1 is crucial for maintaining the integrity of hair follicle structure but is not needed for skin epidermis maintenance in mice.

This study identified changes in immune activation, ferroptosis, and structural genes in alopecia areata subtypes, suggesting molecular markers that might help understand disease variability and guide future treatments.

This commentary discusses how environmental epidemiology has largely neglected the impact of racism on health outcomes, suggesting various solutions to better integrate these considerations into research.

This study found that dandruff-afflicted individuals had a less integrated microbial network on the scalp and hair surface compared to healthy individuals, with more positive interactions and unstable connections.

This review discusses lipid-polymer hybrid nanoparticles for dermatological applications, outlining their structural and formulation advancements, but reports no new clinical results and calls for further research on their therapeutic potential.

This study found significant changes in gene expression related to skin structure and signaling pathways in AEC syndrome skin, offering new insights into the syndrome's molecular underpinnings.

This study found significant structural and compositional differences in hair affected by alopecia areata compared to healthy hair, using a range of physico-chemical investigation methods.

This study reviews the structural and functional aspects of cell-cell and cell-matrix junctions in sebocytes, emphasizing their roles in sebocyte differentiation and sebum secretion, and how these processes may change in pathological conditions, potentially providing insights for new skin disease therapies.

This review discusses the formation and structure of the cornified cell envelope in the epidermis, highlighting biochemical pathways and genetic factors, but presents no new experimental results.

This article discusses how drug molecules integrate into hair fibers, focusing on biological transport mechanisms and physicochemical factors, but reports no new experimental findings.

This study found that treating human hair with vitamin E and γ-oryzanol significantly reduced UV-B-induced structural damage, with γ-oryzanol providing greater protection, especially in female hair samples. The findings highlight these compounds' potential as cost-effective solutions for preserving hair integrity against UV damage.

This study found that pretreatment with KP-Cryst fusion proteins effectively protected Asian and Caucasian virgin hair from thermal damage by maintaining higher water content and preventing structural changes during heat application.

This study observed that exposing human hair keratins to heat or UV treatments led to modifications in cysteine residues, disrupting crucial disulphide bonds and potentially reducing the structural integrity of hair similar to prolonged styling or sunlight exposure.

In this study, researchers observed that EGFR deficiency in the epidermis affects gene expression related to cell differentiation and structure, highlighting spatial and temporal roles of EGFR during skin and hair follicle development.

In this publication, independent scholar Jeffi Chao Hui Wu presents a comprehensive civilization archiving system spanning fourteen domains, highlighting innovative AGI limitations and physiological case reversals, published in ten languages and integrated into global academic infrastructures.

This review derived guidelines for scalp surgery suggesting improved outcomes when avoiding neurovascular structures, preserving tissue integrity, and maintaining hair direction, but it reports no new clinical results.

This review discusses the current state of research on skin organoids, highlighting their potential for replicating complex skin structures and comparing recent studies on stem cell microenvironments.

This study characterized a new human keratin, hK6irs1, specifically found in the inner root sheath of hair follicles, which suggests its role in the structural integrity and guidance of growing hair shafts.

This study introduced a reproducible human model using 3D-SeboSkin technology to study hidradenitis suppurativa, allowing better maintenance of skin integrity and replication of biomarker expression patterns compared to traditional skin cultures, suggesting its value for further research.
