This review explores the complex biological process of hair graying, highlighting oxidative stress, genetic factors, and interventions like antioxidants and genetic therapy as key aspects affecting the preservation of hair pigmentation.

This commentary discusses the cultural and biological significance of hair, intertwined with humorous and poignant anecdotes from cancer care, and reports no new research findings.

This study observed significant differences in hair care practices and biologic hair parameters between Caucasian and African American women, which may contribute to varying hair fragility and growth.

This study found that modern styling cosmetics can significantly alter hair structure through changes in interfacial chemistry and cohesion, particularly when applied to already damaged hair.

This study found that in male mice, microglial changes due to a Parkinson's-like lesion were influenced by sex hormones, with dutasteride treatment preventing some effects.

This study presents the design of an autonomous bioregeneration chamber that aims to extend human lifespan to 130-150 years by optimizing biological and environmental conditions, suggesting that a longer healthspan is possible through technological, nutritional, and socio-economic interventions.

This article reviews postpartum hair loss management strategies, highlighting a lack of thoroughly investigated effective treatments and suggests that new research focus on targeted biological methods.

This study found that the mechanical stiffening of the human hair follicle along the first millimeter is linked to changes in the keratin network architecture and composition during keratinization.

This review discusses the implications of deterministic chaos in pathology, emphasizing its potential impact on predicting biological behavior of lesions, and reports no new experimental results.

In this study, fractional laser treatment was observed to reverse age-related gene expression changes in skin and enhance dermal remodeling, further improved by multiple treatments.

This review discusses the role of Ysc84/SH3yl1 proteins in linking actin regulation to membrane morphology changes but reports no new experimental results.

This chapter provides an overview of chemotherapy-induced alopecia, discussing its biological and clinical aspects, current experimental models and treatments, and calls for improved understanding to prevent and manage it.

In this study involving mice, the researchers observed that circadian rhythm disorder can pass alopecia risk to male offspring, and parental Pu-erh tea consumption, particularly by females or both parents, mitigated this risk through various biological mechanisms.

The abstract reports no new results but discusses Berry's belief that most changes in breast cancer incidence are due to screening, measurement adjustments, or hormone use.

This study found that young men with post-finasteride syndrome may experience erectile dysfunction due to potential histologic changes in penile tissue, despite having normal penile Doppler hemodynamics.

This paper proposes a theory explaining how the normal anabolic effects of androgens lead to structural changes and hair follicle miniaturization, contributing to androgenic alopecia.

In this study, researchers created nanowhiskers from crab shell-derived nanochitin that self-assembled into vibrant structural colors within a film. The material, sensitive to environmental changes, shows potential as a food freshness indicator and a sustainable dye for cosmetics due to chitin's biocompatibility.

In this study, different extracellular matrix types altered growth characteristics of cultured human dermal papillae cells but did not significantly affect their biological function-related characteristics.

In this study, researchers observed that chronic stress affected wild-derived house mice differently by sex, with females showing less weight gain and distinct behavioral changes, while males exhibited higher hair corticosterone levels, suggesting divergent coping strategies and implications for sex-specific stress assessment protocols.

In this study, researchers found that frontal hair follicles in individuals with androgenetic alopecia show a higher biological age compared to occipital follicles, possibly due to decreased expression of the transcriptional repressor TRPS1 in frontal dermal papillae, which may influence follicle miniaturization.

This review highlights recent advances in the use of light exposure for health purposes, examining its role in pathology, therapeutic strategies, and molecular changes, as well as discussing future developments in this globally supported field.

This study suggests that traditional classification systems for pattern hair loss, while useful in the past, have limitations in accuracy and reproducibility, and highlights the potential of integrating digital imaging and AI to create more precise and biologically informed classification frameworks.

This study proposed a new standardized in vitro framework using human hair tresses to evaluate cosmetic hair product performance and found significant improvements in hair breakage, tensile strength, shine, volume, and frizz control compared to a control group without such changes.

This article explores the dynamic and energy-efficient nature of telogen hair follicles, challenging the notion of dormancy, and highlights their potential in advancing treatments for hair growth disorders.

In this study, the authors observed that controlled microflora in gnotobionts leads to delayed maturation of T-dependent lymphocytes in the thymus, affecting cellular immunity reactions.

This study found that essential oils from Hedychium spicatum showed anti-inflammatory, antinociceptive, antipyretic, and antioxidant activities, with site-specific variations in their effectiveness.

This study suggests that breast cancer-associated phospholipids may alter the X-ray diffraction pattern of hair, potentially enabling the development of a sensitive and specific screening test for breast cancer.

This review discusses the fundamental hallmarks of aging as they relate to skin aging and highlights the prominent roles of oxidative damage and the extracellular matrix in photoaging, reporting no new results.

This review discusses how lipid signalling molecules are generated in plants and their role in responding to environmental stress, but it reports no new clinical results.

This review reports on the effects of aging on hair characteristics such as pigmentation, growth, and structural properties across genders and ethnicities, highlighting the importance of scalp health and suggesting cosmetic solutions to improve the appearance of aged hair.
