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 found that topical Rosmarinus officinalis leaf extract improved hair regrowth in mice and inhibited androgen-associated mechanisms involved in hair loss.

This study found that topical application of partial proteasomal inhibitors accelerates hair growth by stabilizing β-catenin and disrupting the hair cycle's normal balance of activation and quiescence.

This cohort study using real-world data found no significant difference in the risk of developing prostate cancer between finasteride and dutasteride among patients with benign prostatic hyperplasia, despite previous suggestions that dutasteride might be more effective.

In this research, the authors identify coordinated mechanical forces as crucial for hair follicle development in mammals, with contractile, proliferative, and proteolytic activities facilitating the formation and sectioning of epithelial structures crucial for forming a functional tissue.

In this study, the researchers found that while the chitosan-alginate gel base supported hair growth, the addition of 0.5% celery extract did not enhance growth, likely due to its low concentration.

In this study, researchers identified three novel genetic loci associated with androgenetic alopecia, including one with significant association in females only, which may indicate a role for sex-specific genetic factors in patterned hair loss.

This study identified a 582-bp deletion upstream of LHX2 in cashmere goats, likely linked to hair follicle development and cashmere production, providing insights into genetic factors in cashmere trait selection.

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 review discusses the role of cholesterol homeostasis in hair follicle biology and its potential connections to various hair disorders, but it reports no new findings.

This case report describes a 5-year-old boy with acquired acrodermatitis enteropathica and normal serum zinc levels, improving clinically after zinc supplementation.

This article proposes a mechanistic model for how platelet-rich plasma therapy may stimulate hair growth in androgenetic alopecia by promoting vascularization and activating specific signaling pathways, but it reports no new experimental results.

This study evaluated a 20% cinchona extract cream and found it increased hair growth length and mass in guinea pigs, demonstrated good physical stability, and did not irritate rabbit skin.

This review describes the molecular interactions between androgens and Wnt/ß-catenin signaling in androgenetic alopecia but reports no new experimental or clinical findings; the authors discuss potential Wnt/ß-catenin-targeted treatments for hair growth.

Hair follicles can regrow in wounded adult mouse skin using a process like embryo development.

This review discusses the roles and mechanisms of Wnt signaling in embryonic and adult stem cells and its association with cancers, and reports no new experimental findings.

This study found that SAMiRNA-AR68, a nanomedicine targeting androgen receptor mRNA, increased hair counts in androgenetic alopecia patients with no observed side effects.

This study found that patients with androgenetic alopecia had deficiencies in certain trace elements and vitamins, which were linked to distinct patterns of hair loss connected to androgen levels.

This study found that millet seed oil effectively promoted hair growth in a mouse model with testosterone-induced hair growth inhibition, suggesting its potential use in preventing or treating androgenetic alopecia.

In this study, three different hair serums were tested for their impact on Telogen effluvium in adult females, finding all effective in reducing hair shedding, with the cytokine-based serum showing the most significant improvement, reducing hair fall by 54.6% without adverse effects.

This study found that combining scalp repair serum microneedles with oral and topical medications significantly improved hair regrowth in patients with moderate to severe androgenetic alopecia.

This study observed that in the bald scalps of male patients with androgenetic alopecia, there was a significant downregulation of the PPAR signaling pathway, suggesting reduced adipogenesis potentially influencing hair cycling processes.

This study tested a natural hair dye made from papaya seed extract, celery leaf, and avocado, finding color change in animal hair but also noting tissue changes like hyperkeratosis.

This study suggests that Silybum marianum flower extract may promote hair growth and reduce hair loss by increasing proliferation and VEGF production in dermal papilla cells and suppressing cell senescence.

In this study, yeast fermentation of Platycladus orientalis leaves was shown to enhance hair growth-promoting properties by affecting cell cycle phases in human dermal papilla cells, increasing growth factor VEGF, reducing inflammatory factor TGF-β1, and altering the expression of Wnt/β-catenin pathway-related genes.

This study found that of the many ingredients advertised in shampoos as effective against hair loss, only caffeine, adenosine, placental proteins, and melatonin have limited clinical evidence supporting their efficacy, with most claimed active ingredients lacking any trial-based validation.

In this experimental study using male rabbits, researchers found that a 7.5% concentration of green tea leaf ethanol extract hair tonic was nearly as effective in promoting hair growth as the positive control, minoxidil, over a 21-day period.

This study identified altered mRNA and lncRNA profiles in NS scalp tissues, highlighting CDKN2AIP as a downregulated gene involved in a ceRNA network.

This review discusses the increased incidence of hair loss and telogen effluvium among COVID-19 patients and evaluates existing evidence for regenerative treatments like PRP and HFSCs, finding limited published data.

This study found that topical application of the BRAF inhibitor vemurafenib improved wound healing and promoted hair follicle regeneration in a diabetic murine model.
