This review discusses the role of oxidative stress in hair greying and suggests that understanding melanocyte susceptibility at different follicular locations may help develop therapies for preventing and reversing the process; it reports no new experimental results.

The authors describe drug repurposing as a promising strategy for finding new uses for existing drugs, noting it is efficient, cost-effective, and poses lower risks than traditional drug discovery processes, potentially aiding in the treatment of rare and difficult-to-treat diseases.

This study concluded that hair follicle hyperplasia found in pseudolymphomatous folliculitis can also occur in genuine cutaneous lymphomas, potentially as a coincidental result of underlying pathological processes.

This study found that in mice lacking EGFR, elevated Wnt signaling disrupts hair follicle development by affecting cell proliferation and differentiation, revealing a critical role for EGFR in regulating these processes.

This review discusses the role of lysophosphatidic acid in skin physiology and pathology, highlighting its significance in processes like wound healing and hair follicle development, but reports no new clinical findings.

This review discusses the broader roles of angiogenic factors, like VEGFs and FGFs, beyond angiogenesis, highlighting their involvement in various biological and pathological processes.

This study found significant differences in gene expression between newborn and adult skin, with infant skin notably increasing processes related to ECM organization, cell adhesion, and collagen fibril organization.

This study identified the placenta at the base of the ovary as the origin of poplar seed hair development and detailed transcriptome dynamics during the growth process.

This study found that maternal sub-maintenance nutrition reduced the density and branching ratio of secondary wool follicles in Merino sheep fetuses and identified genes potentially involved in these processes.

This study presents recombinant human hair keratins K31 and K81, observing novel nanostructures from their self-assembly and emphasizing disulfide crosslinking's role in this process.

This study investigated the formation of Type III brush hair in Chinese Haimen goats and identified genetic factors that may involve heat stress in the process.

This study found that epidermal stem cell-specific Jag1 expression levels are crucial for effective wound healing and scar reduction, and porcine acellular dermal matrix treatment enhances this process in mice by boosting Notch/Jagged1 signaling.

This study found that taxol induces apoptosis in dermal papilla cells, affecting protein expression related to biological processes and potentially contributing to taxol-induced alopecia.

This review assessed experimental studies on herbs used for alopecia, identifying potential mechanisms involving hair cycle management and keratinocyte processes, but highlighted a need for improved evidence on quality control and toxicity of these herbal treatments.

This study identified differentially expressed proteins and pathways potentially involved in wool bending in Zhongwei goats, with specific genes like COL6A1 and CRNN emerging as important candidates in this process.

This study identified CD201+ fibroblast progenitors in mouse skin that regulate wound healing through differentiation into specialized cell types, with retinoic acid and hypoxia influencing this process.

This study identified 617 differentially expressed genes in cashmere goat hair follicles, which are involved in key biological processes and provide insights into hair follicle development.

This study identified 374 eQTLs in scalp hair follicles associated with genes involved in metabolic, mitotic, immune processes, and responses to steroid hormones, contributing insights into genetic variation and hair traits.

In this study, AgK114 was found to be transiently induced in hamster epidermal keratinocytes following skin damage, suggesting its role in the recovery process after injury.

This study found that exposing adult esophageal epithelial cells to skin stroma can induce them to transition toward a hair follicle identity, with HIF1a playing a crucial role in this conversion process.

In this study, overexpression of miR-29 in mice led to aging-related phenotypes and early lethality, demonstrating its significant role in driving aging processes.

This chapter discusses the role of hormones in regulating reproductive biology and outlines how the endocrine system, particularly the brain and pituitary gland, controls these hormonal processes.

This review covers hair dye formulations, their mechanisms, and potential applications, but reports no new findings; the authors highlight the process of oxidative dyeing and repairing damaged hair.

This study introduces "Homeodynamic Rejuvenation" as a method to restore the skin's resilience by enhancing its ability to detect and recover from stress, focusing on five core biological processes critical for maintaining skin function and health amidst environmental and metabolic challenges.

In this study of 131 healthy men aged 30 to 45, no relationship was found between androgen receptor gene polymorphisms related to androgen sensitivity and biological age markers, suggesting that other factors may influence the aging process independently of these genetic variations.

This review assessed the role of scalp hair Survivin protein in individuals with premature graying, exploring its potential involvement in graying-related processes and highlighting its overexpression in autoimmune diseases that may influence the survival of specific immune cell clones.

In this study on mice, researchers observed that dermal white adipose tissue (dWAT) plays a key role in regulating skin inflammation and tissue repair; however, reduced expression of certain cytokines in obese mice may hinder these processes, indicating potential metabolic disruptions in dWAT during inflammation.

This study found that Plant Elicitor Peptides enhance root hair growth through a mechanism independent of their known receptors, with PROPEP2 playing a key role in this process by influencing gene expression related to root hair formation.

In this mouse study, the absence of the Ascl4 gene did not affect the development of hair follicles, teeth, or mammary glands, suggesting it is non-essential for these processes.

This study observed that patients with type 2 diabetes and sensorineural hearing loss exhibited significantly higher levels of peripheral myelin protein 22, particularly in those with microangiopathies, suggesting demyelinating processes in the auditory system.
