This review discusses the role of Wnt/β-catenin signaling in hair follicle regeneration and highlights recent progress in developing hair loss treatments targeting this pathway, but reports no new clinical results.

This study concluded that oral minoxidil is an effective and well-tolerated alternative to topical minoxidil for healthy patients struggling with application-related compliance issues.

This review discusses the biology and signaling mechanisms of dermal papilla cells in hair follicle growth and reports no new clinical results; the authors emphasize the importance of optimizing culture conditions for hair restoration.

In this study, researchers developed a new self-administered finasteride delivery system using powder-carrying microneedles that improved hair growth efficacy and addressed safety concerns compared to topical finasteride gel by allowing sustained intradermal release of the drug for three days with a single application.

This study found that ginsenoside Rb1 promoted the growth of mink hair follicles and dermal papilla cells, potentially through activating the PI3K/AKT/GSK-3β signaling pathway.

In this study, hydrolysates of lactic acid bacteria were found to enhance hair growth in C57BL/6 male mice more effectively than 5% minoxidil.

This study found that male pattern baldness in European males is strongly heritable and associated with genetic markers linked to earlier puberty, bone density, and pancreatic function.

This study found that in vivo, a novel microneedle system for valproic acid delivery may improve hair regrowth efficacy by upregulating hair follicle development pathways more effectively than topical application.

This review discusses the molecular mechanisms of androgens and androgen receptors in skin disorders, particularly androgenetic alopecia, and reports no new clinical results; it highlights potential areas for future treatment development.

This study found that red ginseng oil and its major components improved hair regrowth in testosterone-treated mice by promoting an earlier anagen phase and altering related gene expressions.

In this study, topical tofacitinib significantly increased hair regrowth in mice compared to minoxidil or vehicle, potentially due to elevated VEGF levels and reduced inflammation.

In this study, Geranium sibiricum L. extract promoted hair growth in vitro with human dermal papilla cells and in vivo in mice, outperforming minoxidil by proliferating cells and stimulating growth factor expression, suggesting its potential as a hair growth treatment.

This study found that activating Nrf2 in human hair follicles significantly reduced oxidative stress, lipid peroxidation, and protected against hair growth inhibition, suggesting a protective role for Nrf2 against redox insult in this context.

This study found that repeated microneedle stimulation in mice promoted hair growth and increased the expression of hair-growth-related genes, suggesting potential therapeutic uses for alopecia.
