This narrative review discusses the discovery of plasticity in epidermal stem cells using single-cell transcriptomics, but reports no new results; it highlights the potential implications for regenerative medicine.

This study demonstrates that trichogenic dermal papilla cells are crucial for hair regeneration in engineered skin substitutes, with adult murine cells showing higher activity than adult human cells.

This opinion from the EFSA Panel concludes that the health claim regarding spermidine prolonging the anagen phase of the hair cycle does not meet regulatory criteria as it is related to disease treatment.

The study found that stratum corneum thickness and total epidermal lipid content influence the permeation rates of certain nonsteroidal anti-inflammatory drugs in various animal skin models, and suggests porcine skin as an effective human replacement in diffusion experiments.

This study reports the development of an artificial skin membrane incorporating hair follicles, intended as an in vitro model to better estimate drug permeation with less variability than current models used in transdermal drug delivery research.

This thesis reveals that tenuazonic acid inhibits plant plasma membrane H+-ATPase, suggesting its potential as a herbicide due to its impact on root elongation and cell viability in Arabidopsis thaliana.

This study concludes that anti-androgenic chemicals causing short anogenital distance in male fetuses also induce a feminized transcriptional profile in the perineum, implicating Wnt and estrogen signaling in the process.

This paper analyzes Hilary Mantel's memoir and suggests that conflicts between her bodily experiences and psychological identifications affected her acceptance of a female gender identity, influencing her experience of endometriosis.

Activating the Eda/Edar pathway improves wound healing by enhancing hair follicle growth.

This article discusses the anatomical and biological aspects of hair follicle stem cells in the bulge region but reports no new research findings.

This review explores the potential of targeted topical drug delivery to hair follicles for treating conditions like acne and hair loss but reports no clinical results, emphasizing the need for more research.

This study found that the newly developed microarray patches for intradermal delivery of finasteride showed high drug content and significantly improved skin deposition compared to existing methods.

This review identifies several off-label uses of H-1 antihistamines in dermatology beyond itch and urticaria control, though the evidence is weak and further trials are needed.

This study identified significant genetic associations with frontal fibrosing alopecia at four genomic loci, suggesting it is a genetically predisposed immuno-inflammatory disorder influenced by the HLA-B*07: 02 allele.

This study reported that pulverizing hair samples significantly improves the precision of testosterone measurement, with higher testosterone concentrations observed in men than in women.

This study found compelling genetic evidence linking atopic and allergic conditions with the development of alopecia areata, suggesting a need for closer monitoring in affected individuals.

This study found that patients with rheumatoid arthritis, atopic dermatitis, and alopecia areata receiving baricitinib had low incidence rates of adverse events, especially among low-risk individuals, with varying rates among those at higher risk.

According to this worldwide systematic review, psoriasis is a prevalent disease with adult prevalence ranging from 0.53% to 11.48%, more common in older populations and with substantial knowledge gaps in low and middle-income countries.

This article discusses the inequalities in COVID-19 outcomes affecting vulnerable groups in the UK and calls for more inclusive global pandemic strategies, but presents no new empirical data.

Scalp hypothermia can prevent chemotherapy-induced hair loss but is not suitable for all patients, and more research is needed to improve prevention methods.

This study found that both a proprietary ultrahigh-pressure extract and a hexanic extract of saw palmetto showed comparable inhibition of 5α-reductase, suggesting similar potential for managing symptoms of benign prostatic hyperplasia.

In this study, subcutaneous injection of mesenchymal stem cell-conditioned medium promoted regeneration of mice skin aged by D-galactose, improving skin thickness, vascularization, and collagen density.

This study found that topical mesenchymal stem cell conditioned medium improved skin structure by increasing collagen fiber density, hair follicles, and blood vessel number in a mouse model of skin aging.

This article discusses the long-standing use and safety of opioids in anaesthesia, noting that respiratory depression is a manageable side effect due to the availability of opioid antagonists.

This study found that treatment with a 1550 nm fractional erbium–glass laser increased hair density and thickness in women with female pattern hair loss, suggesting it may be an effective and safe option.

This study found that as Korean women age, their hair density, diameter, tensile strength, and lustre decline, while grey hair ratio and certain sterol contents increase, suggesting unique ageing features compared to women in other countries.

A specific gene mutation causes severe skin and nail issues and hair loss.

This study found that human scalp hair significantly reduces solar radiation intake, with more tightly curled hair offering greater protection against heat gain compared to a naked scalp.

This paper presents consensus guidelines for standardized diagnostic criteria and assessment methods for frontal fibrosing alopecia to improve clinical research and data collection globally.

This study found that a commercially available shampoo significantly increased hair counts and reduced hair shedding in Korean subjects with alopecia over 16 weeks.
