This paper reviews hair structure and damage from grooming and cosmetic exposure but reports no new clinical findings; it suggests collaboration between dermatologists and cosmetic chemists to improve hair care products.

This article explains the structure and multifunctional roles of the human skin, including its protective, regulatory, and sensory functions, but does not report new research findings.

This study reports that structural abnormalities in the inner root sheath of hair follicles may cause the hair shaft to be loosely attached in patients with loose anagen hair syndrome.

This review discusses the structure and regenerative potential of hair follicles, highlighting their role in wound healing, stem cell populations, and keratin-based biomaterials, but it reports no new clinical results.

This review discusses the structure, expression, regulation, and potential roles of NcoA4 in cancer and other pathologies, reporting no new experimental findings.

This article illustrates that dermoscopy can quickly diagnose hair breakage due to intrinsic and chemical factors in patients of African descent, although published findings are limited.

This review discusses the structure, functions, and growth cycle of human hair, emphasizing its reduced growth and protective roles, and reports no new research findings.

This review summarizes the structural and chemical characteristics of current and novel antiandrogenic drugs but reports no new clinical findings.

This study found that structural defects in the hair shafts of sighthounds with bald thigh syndrome are related to a downregulation of genes and proteins essential for hair shaft formation.

In this study, researchers observed that acute stress increased levels of the enzyme 5αR2 in the medial prefrontal cortex of male rats, affecting stress reactivity, but this effect was not seen in females.

This review outlines the histological structures of the skin, highlighting species and regional differences in dermal absorption and obstacles encountered in toxicological assessments due to epidermal thickness variability, contact dermatitis reactions, and stem cell vulnerabilities.

This article reviews the structure and regulation of the ITGB6 gene and discusses its role in integrin αvβ6 expression, with no new experimental results reported.

This review discusses the structure and function of steroid nuclear receptors, particularly focusing on androgen receptor dysregulation in prostate cancer and androgen insensitivity syndromes, without reporting new experimental results.

This study in a Pakistani family identified a novel ST14 gene variant as the likely genetic cause of autosomal recessive ichthyosis with hypotrichosis syndrome.

This chapter reviews the structure, pharmacokinetics, and clinical applications of PEGylated liposomes and reports no new research findings.

This review discusses advances in understanding hair and hair follicle structure, gene expression, and molecular signals in hair formation, without reporting new clinical findings.

This study found that the human hairline is closely linked to several cranial, cerebral, and vascular structures, enabling precise localization of key neuroanatomical landmarks, which could assist in planning neurosurgical procedures.

This review highlights the hair follicle's structural and functional properties as an effective route for delivering active compounds in treating hair disorders, focusing on emerging carrier technologies to enhance targeted transfollicular delivery.

Researchers observed that dutasteride and finasteride caused structural changes in the penises of both control and hypertensive rats, with dutasteride having a more pronounced effect on the corpus cavernosum.

This narrative review provides an overview of the persistent dermatological side effects experienced by cancer survivors due to treatments, highlighting their impact on quality of life and the need for structured dermatological care during survivorship.

This study found that K17 is crucial for the structural integrity and survival of hair-producing cells, with K17 null mice developing alopecia due to hair fragility and follicular alterations.

The researchers reported that hair follicle germinative epidermal cells can form complex structures when associating with papilla cells in culture, unlike other types of epidermal cells.

This review provides an in-depth analysis of the structure and function of c-kit activation, and its role in both normal physiological and pathological conditions, with no new research findings reported.

This study found that deleting FoxN1 in specific thymic epithelial cells disrupted the 3D thymic structure and led to age-dependent formation of 2D epithelial cysts, highlighting FoxN1's critical role in thymic morphogenesis.

This study found that finasteride impaired object recognition memory and altered hippocampal dendritic structures in male 3xTg-AD mice, suggesting potential sex differences in Alzheimer's disease pathology.

This study demonstrates that Rac1 activity is essential for normal hair follicle formation but influences hair structure and pigmentation, in terminal differentiation, through alterations in hair shaft, cuticle, and pigmentation organization.

This study found that mink pelts with "singe" and "red hip" defects often exhibit split hair tips and altered cuticle structures, which may contribute to their undesired metallic sheen.

This review suggests that the inner root sheath of human hair follicles may have broader regulatory roles beyond structural support, potentially impacting processes like folliculogenesis, anagen phase regulation, and immunomodulation.

This study found that fish oil supplementation in male Wistar albino rats helped maintain hair shaft structure and improved amino acid composition, while reducing harmful protein compounds associated with diabetes and hypercholesterolemia.

This study observed that long-term laser hair removal in women may alter hair follicle structures and stem cell interactions, with dermal fibrosis potentially influencing hair regrowth prevention.
