Certain ingredients can help protect hair color.

The new compounds may be more effective and cheaper than current treatments for conditions like baldness.

This study observed that the degradation product PTeCA significantly increased in hair treated with oxidative cosmetics, suggesting it could be a reliable marker for detecting such treatments, with a proposed PTCA cut-off value using PTeCA as the gold standard.

This study developed and tested Bicalutamide-loaded lipid vesicles in dissolving microarray patches for topical application, finding that they effectively deliver Bicalutamide through murine skin while maintaining a favorable safety profile, suggesting potential to improve treatments for androgenetic alopecia.

This chapter reviews the hair follicle's role in drug and chemical penetration through the skin but does not present new experimental findings.

In this study, the researchers identified MJ04, a selective JAK3 inhibitor, as a promising candidate for promoting hair growth, demonstrating efficacy in both animal models and human hair follicle assays with a favorable safety and pharmacokinetic profile.

This study found that ionizing radiation primarily affects keratinocyte stem cells in the hair follicle, suggesting they play a central role in radiation-induced hair graying, rather than melanocyte stem cells.

This study investigated chitosan–hydroxyapatite biocomposites, finding them to enhance anti-inflammatory cytokine expression, support cellular activities, and reduce pro-inflammatory cytokines in a dermatitis model, while highlighting gaps in understanding their immune modulation and issues with reproducibility for clinical use.

This chapter discusses the skin stem cell niche as a complex ecosystem and highlights the diverse components and interactions that influence stem cell function, but it reports no new experimental results.

This study concluded that noninvasive imaging techniques offer potential benefits in managing scalp conditions by potentially reducing the need for biopsies and minimizing patient morbidity, each technique having unique advantages and limitations for specific conditions.

This study used an ex vivo human skin model to show that tropical conditions disrupt skin homeostasis, resulting in epidermal thickening and junctional flattening, and found that Kombucha tea extract may help preserve skin structure under such stress.

This study found that oral administration of Terminalia bellirica enhanced hair growth in testosterone-suppressed conditions in both human cell and mouse models, outperforming finasteride, a current commercial hair loss treatment.

This review outlines the practical use of reflectance confocal microscopy in dermatology, detailing its applications and considerations for diagnosing various skin conditions, but reports no new findings.

This study demonstrated that PGF 2α significantly stimulates hair growth in human hair follicles via a receptor-driven mechanism, with a notably stronger response in intermediate follicles than in terminal ones, suggesting potential clinical significance for conditions like alopecia.

This study reported that adipose-derived stem cell-conditioned medium demonstrated anti-tumorigenic effects on B16 melanoma cells both in vitro and in vivo, indicating potential for future melanoma treatment.

In this study, researchers developed and tested a gel containing apocynin-loaded nanoparticles that showed promising results in treating rheumatoid arthritis in rats, suggesting potential for novel topical treatments in inflammatory conditions.

This study found that keratin 19 may be a marker for skin stem cells, helping to characterize these cells in different conditions and potentially explaining variations in healing rates between children and adults.

This study found that the combination of epidermal growth factor and Jagged1 significantly stimulated hair growth in mice with androgen-suppressed conditions, suggesting potential therapeutic implications for androgenetic alopecia.

This review highlighted that in an in vitro setting, 3D spheroid cultures of fish cells offer a promising alternative to traditional monolayer cultures, potentially advancing research in eco-toxicology, immunology, drug screening, and more by better mimicking in vivo conditions.

This study demonstrated that human skin can be efficiently reinnervated using human induced pluripotent stem cell-derived neural stem cells, promoting skin vitality and sensory reinnervation comparable to physiological conditions.

This study found that γδTregs significantly reduced autoimmune effects in humanized alopecia areata models, suggesting their potential as a novel cell-based therapeutic approach for managing the condition.

This article reviews the possible therapeutic activities of Angelica gigas Nakai root extracts and their components, noting their potential effects on neuro-cognitive, metabolic, and other health conditions, and reports no new clinical results.

This study suggests that rather than inhibiting IL-15, selectively stimulating IL-15Ra-mediated signaling could be beneficial for managing alopecia areata and possibly other inflammatory hair loss conditions, as IL-15 promoted hair growth and maintained immune privilege in human hair follicles.

In this study, researchers developed a novel topical gel combining minoxidil and JAK inhibitor tofacitinib, which effectively enhanced hair follicle growth and reduced local inflammation in mice with alopecia areata, suggesting a new approach for treating this condition.

This study suggests that bovine and fish-derived collagen peptides may help maintain or prolong the hair growth phase and balance hair follicle stem cell populations, potentially benefiting aging and hair loss conditions like androgenetic alopecia.

This study found that anisotropic osmolyte solutions may improve hair follicle turnover and condition in both in vitro and in silico models, as well as in human volunteers with hair disorders.

This study found that in female dogs, exposure to free fatty acids increased androgen production, suggesting a potential link to factors characteristic of polycystic ovary syndrome.

In this study, bioengineered hair germ microspheres made from HME hydrogels promoted hair follicle regeneration in vivo, suggesting a promising approach for hair loss treatment.

This review highlights advancements in nanoemulgel platforms for topical and transdermal drug delivery, noting their improved safety and efficacy over conventional treatments in in vitro and in vivo studies, specifically for conditions like skin diseases and inflammatory issues.

This study found that using ectopic expression of CD24 is a promising approach for selecting genetically modified human epidermal stem cells for safe cutaneous gene therapy in cancer-prone conditions.
