This narrative review outlines the biological costs of hair extensions, such as traction leading to hair loss and scalp issues, and suggests a prevention-focused model involving risk assessment, surveillance, and tiered therapies to minimize alopecia risk and maintain scalp health.

This study found that TRF1 plays a crucial role in maintaining pluripotency and stem cell compartments, but it is not a suitable in vivo telomere length marker.

This paper reviews the surface degradation of hair and describes how combining 18-MEA with specific surfactants can maintain hydrophobicity on bleached and weathered hair surfaces.

This review explores recent advancements in understanding how various physiological and psychological factors, such as stress and aging, influence epidermal stem cell populations, highlighting their importance in immune-related skin disorders and potential for clinical applications.

This review highlights the potential of microneedles for immunotherapy, emphasizing their ability to enhance immune responses and reduce side effects through precise and stimuli-responsive delivery, especially in tumor treatment, while also noting the limitations and areas for improvement in current systems.

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 found that actomyosin contractility in suprabasal keratinocytes influences the proliferation and differentiation of epidermal stem/progenitor cells by acting as a niche element in the skin.

In this study, researchers found that connexin 43-negative cells in the basal layer of the epidermis could serve as markers for keratinocyte stem cells, aiding their identification and separation.

This study shows that alpha 6 + /MHCI - cells have gene expression profiles similar to hair follicle stem cells, suggesting they may be enriched for stem cells.

This study observed that lipids in human hair accumulate in specific areas and do not significantly impact water permeability, highlighting the utility of AFMIR for studying complex biomaterials.

This article presents a comprehensive overview of hair microscopy techniques and their diagnostic potential for systemic and cutaneous disorders, emphasizing its usefulness in resource-limited settings and highlighting the underutilization of this non-invasive method due to lack of awareness.

AA-PRP temporarily increases hair density in androgenetic alopecia but loses effectiveness over time.

This study found that mesenchymal progenitor cells from human hair roots seeded onto polymer scaffolds stimulated the production of mineralized proteins, enhancing bone-like structures, with optimal results at a pore size of 35 µm.

In this study, NuMA's microtubule-binding domain was found to be crucial for correct spindle orientation and skin differentiation, with its loss leading to neonatal lethality in mice.

In this study, desmopressin-loaded elastic liposomes (ODEL1) showed improved permeation and drug deposition across rat skin by altering the skin's cohesive energies and causing reversible changes on its surface.

This review categorizes contractile hydrogels by their contraction mechanisms and explores their role in advanced wound management, emphasizing mechanical and biochemical signaling in healing, but also notes challenges like force transmission and clinical applicability.

This review describes bioengineering strategies to mimic the natural cell microenvironment in vitro, emphasizing the novel approach of using cell-synthesized extracellular matrix as a scaffold for engineering functional 3D tissues, while highlighting the limitations of exogenous scaffolds in tissue engineering.

This study found that the NuMA protein's microtubule-binding domain is essential for proper spindle orientation and differentiation in keratinocytes, affecting skin and hair development in mice.

This abstract reviews hereditary vitamin D-resistant rickets, a rare genetic condition causing severe early childhood rickets, and reports no new results; effective treatment typically requires high doses of calcium to address hypocalcemia and secondary hyperparathyroidism.

This study found that 17β-estradiol inhibited RANTES production in human keratinocytes by suppressing nuclear factor κB activity, suggesting a potential mechanism for 17β-estradiol's modulation of psoriasis-related inflammation.

This study found that proper levels of retinoic acid, controlled by the enzyme Cyp26b1, are essential for normal hair follicle development and morphogenesis in mice.

This review discusses the role and interactions of the calcium-binding protein S100A6 in cellular processes and its association with various diseases, highlighting the need for further research to fully understand its biological impact.

This study found that C. japonicum flower extract significantly increased melanin content and cellular activity in human melanocytes and may improve follicular depigmentation and vitiligo through cAMP signaling.

The researchers reported that PEG-FGF2 conjugates, particularly Compound 6, significantly enhanced stability, proliferation, migration, and wound healing activity compared to native FGF2, despite some reduction in bioactivity near crucial binding domains.

This study found that women with PCOS had higher levels of serum phoenixin isoforms, which correlated with reproductive and metabolic markers, suggesting these isoforms may have a potential diagnostic role.

This study found that triglycerides, testosterone, and SHBG levels were associated with hyperandrogenism in women with PCOS, while FGS was not linked to this condition.

In this study, XZYFD, a Traditional Chinese Medicine formulation, was found to improve androgenetic alopecia in a testosterone-induced mouse model by promoting hair regrowth, restoring follicular morphology, and modulating androgen metabolism, MAPK signaling, and lipid metabolism pathways, suggesting potential benefits for patients with metabolic dysfunction.

This book chapter reviews the genetic and epigenetic factors influencing PCOS, particularly in a global context and specific to India, and reports no new clinical findings.

In this study, researchers investigated factors predicting resistance to clomiphene citrate in women with anovulatory PCOS, identifying AMH and SHBG levels as significant indicators, but they found no reliable thresholds for predicting resistance to the standard 50 mg/day dose.

This study found that non-alcoholic fatty pancreas disease is significantly more prevalent in women with polycystic ovary syndrome, and is associated with metabolic syndrome, insulin resistance, and hyperandrogenism.
