This review examines new formulations for delivering 5-α-reductase inhibitors to improve targeted drug delivery in androgenetic alopecia, but reports no new clinical results.

This study observed that the loss of H3K9me3, via the ablation of Suv39h1, Suv39h2, and Setdb1 in embryonic mouse epidermis, disrupts skin development processes such as keratinocyte differentiation and hair follicle formation, highlighting H3K9me3's crucial role in epidermal morphogenesis.

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 review found that exposure to pollutants like PM, NOx, and PAHs is linked to various skin and hair disorders, indicating a need for cosmetics with natural adsorbents to reduce pollutant effects, achieving 30-55% removal efficiency.

In this review, researchers discuss the role of epigenetic modifications in epidermal stem cells' decline during skin aging and identify potential interventions targeting these disruptions, suggesting significant possibilities for antiaging strategies and dermatological treatments.

In this study, a bleaching protocol was developed to evaluate hair repair products, revealing that K18® and Olaplex® improve hair brightness and lightness, with distinct impacts on hair fiber properties.

This review discusses recent insights into the dynamics and regulation of the epidermal differentiation complex during keratinocyte differentiation and reports no new experimental results.

This study developed a deep learning-based tool to quantify individual hair fibers in mice, revealing distinct hair phenotypes linked to hormonal, genetic, and age-related factors, and suggesting its potential for new diagnostic methods through hair analysis.

This study found that prevelex coatings on microwell array devices enhanced the formation of uniform cell spheroids and enabled the development of hair follicles in tissue engineering applications.

This study describes how shotgun proteomics can identify over 300 proteins in hair shafts, potentially allowing for the diagnosis of diseases through noninvasive human proteome sampling.

This paper critically reviews recent advances in the use of keratin-based biomaterials, highlighting their potential applications in wound healing, drug delivery, and tissue regeneration due to their biocompatibility, biodegradability, and ability to support cell growth.

This review synthesizes current evidence on platelet-rich plasma for dry eye disease and reports no new results; the authors emphasize the need for standardized trials to validate these approaches.

This article highlights that trichorrhexis nodosa, a common type of hair breakage, is influenced by factors like heat styling and chemical treatments, with potential FDA action on formaldehyde usage in hair products potentially altering its treatment approach.

In this study, researchers observed that even a single session of hair dyeing can damage hair fibers, with significant worsening of mechanical properties and protein composition after three or more consecutive treatments, emphasizing the need to consider the cumulative impacts of dyeing on hair health.

This study hypothesizes that the curling of hair may result from the contraction of the Arrector Pili Muscle, contributing to the diverse types of curly hair.

In this study, researchers observed that heat stress significantly affected hair and skin traits in two indigenous goat breeds, with Kodi Aadu goats demonstrating greater thermal resilience compared to Kanni Aadu goats, potentially due to differences in gene expression and methylation.

This study found that Sonic Hedgehog protein treatment enhanced the sprouting and regeneration of pelvic ganglia and cavernous nerves after injury, with localization of delivery affecting outcomes.

This study found that surface modified nanoparticles showed increased skin permeation and improvement in allergic contact dermatitis, independent of the follicular pathway.

This study found that hydrophobic lipid-coated silica nanoparticles penetrated deeper into human stratum corneum compared to their hydrophilic counterparts, highlighting the influence of surface polarity on skin penetration.

This study suggests that behavior modification, semistarvation ketogenic regimens, and surgical therapy could be experimental approaches for different degrees of obesity, with their efficacy varying by the degree of weight excess.

This study found that scalp cooling resulted in visible hair retention in 53% of breast cancer patients undergoing Epirubicin/Cyclophosphamide and Paclitaxel treatment, with factors like hair bulb diameter, shaft diameter, and anagen rate significantly predicting outcomes.

This study reviews the evolution and modifications of microneedle drug delivery systems, initially designed for percutaneous use, now expanded for targeting a variety of tissues and organs such as ocular, oral mucosal, and gastrointestinal, suggesting widespread future applicability.

This review highlights that the RNA modification N⁶-methyladenosine (m⁶A) plays a crucial role in regulating wound healing and tissue remodeling, with dysregulation contributing to complications in chronic wounds, such as diabetic ulcers and burn injuries, through mechanisms like impaired angiogenesis and increased oxidative stress.

In this study, researchers found that L-cysteine interacted electrostatically with anionic ions on the surface of keratin fibers in human hair, reducing the rate of disulfide bond disconnection at pH 9.0.

This article reviews existing and emerging treatments for psoriasis, focusing on therapy modifications due to scientific advancements, but it does not report new clinical results.

This study observed that direct hair transplantation, as a modification of follicular unit extraction, was effective in improving baldness in the majority of treated male patients.

In this study, PDO, PLLA, and PCL thread implants in ageing rat skin did not alter MMP1 gene expression but maintained collagen levels similar to young skin without UV-B exposure, suggesting possible benefits for skin collagen but not gene expression modification.

This article highlights the versatility and potential of alginate and its derivatives in tissue engineering applications, discussing their properties, modification techniques, and various uses in enhancing tissue healing, bone regeneration, and cell growth.

This article reviews management strategies for PCOS and reports no new clinical results; the authors highlight oral contraceptives, lifestyle modifications, and metformin as key interventions.

This review discusses mammalian models of epimorphic regeneration to define a vertebrate regeneration blastema, concluding that regenerative failure likely stems from cellular responses to the microenvironment after injury, not progenitor cell availability, and calls for targeted modification studies in mammals to advance human regeneration.
