This study demonstrated that stress inhibited hair growth in mice, likely through substance P-dependent activation of immune cells, highlighting a brain-hair follicle connection.

This article reviews the history and impacts of direct-to-consumer advertising of prescription drugs in the U.S. and reports no new research findings; it discusses implications for health policy debates.

This study suggests that oxidative stress may contribute to androgenetic alopecia by inducing premature senescence and secretion of hair growth inhibitors in dermal papilla cells from balding scalp.

This study found that hair thickness and density increased after treatment with human follicle mesenchymal stem cells and platelet rich plasma, associated with enhanced Wnt signaling and platelet derived growth factors.

This paper discusses the variability in COVID-19 susceptibility and severity, emphasizing factors like biological differences and suggesting potential precision medicine approaches, but it reports no new clinical results.

This review discusses the psychological impact of alopecia on women and reports no new clinical findings, highlighting the effect on self-esteem and quality of life.

In this study, UVB irradiation of organ-cultured human anagen hair follicles in vitro reduced hair elongation and increased cell death, affecting hair growth and regulatory processes.

This study found that JunB, a transcription factor, is crucial for maintaining epidermal-pilosebaceous stem cell homeostasis by regulating progenitor cell behavior and preventing sebaceous gland dysfunction.

This study demonstrated effective delivery of CRISPR/Cas9 components to dermal papilla cells in androgenic alopecia animals using ultrasound-activated nanoparticles, resulting in specific gene editing and hair growth recovery.

This review found that low-level laser therapy appears promising in improving hair regrowth and patient satisfaction in androgenetic alopecia, though results should be interpreted cautiously.

This article reviews factors affecting follicular unit extraction, emphasizing the need to tailor procedures to individual patient characteristics, but reports no new experimental findings.

This study reported significant upregulation and release of S100A4 in psoriatic skin, which may actively contribute to psoriasis pathogenesis.

This study found that autophagy plays a novel role in human hair growth, with altered autophagic flux during hair development phases influencing hair follicle behavior in a preclinical model.

This study found that deleting Stim1 and Stim2 in mature T regulatory cells disrupts Ca 2+ signaling, preventing their differentiation and leading to severe autoimmune disorders in mice.

This article discusses isotretinoin for severe acne vulgaris, noting its effectiveness but also highlighting significant side effects on skin, mucous membranes, and hair; it reports no new clinical results.

This case report found that two women developed toxic selenium levels after consuming paradise nuts, resulting in symptoms like massive hair loss and nail discoloration.

This study found that TSC2-null fibroblast cells from TSC skin hamartomas can induce hair follicle formation and hamartomatous changes in keratinocytes, with active mTOR signaling observable in a mouse xenograft model.

This review discusses the current evidence and highlights gaps in research needed for the wider acceptance of low-level laser therapy as a treatment for hair loss; no new clinical results are provided.

This study found that in adult mouse skin, reduced levels of histone H3 K4/K9/K27me3 during hair follicle stem cell quiescence are linked to proper tissue homeostasis.

In this study, the combination of SCF and ET-1 was found to significantly enhance skin pigmentation and melanin content in human skin xenografts on SCID mice compared to either treatment alone.

This study observed that NSPC predominantly differentiated into neurons when exposed to serum fractions with molecules under 100 kDa, particularly with biomaterial and fibronectin, in the presence of basic fibroblast growth factor.

This study reported that a new laser scanner using 655 nm red and 808 nm infrared lasers significantly improved hair density in patients with androgenic alopecia compared to both a laser hat and no treatment, without observable adverse effects.

In this study, researchers found that homologous PRP (h-PRP) significantly increased hair density more than both nonactivated (n-PRP) and activated (a-PRP) autologous PRP in patients with androgenetic alopecia, suggesting h-PRP as a potentially more effective treatment option for hair loss.

This study found that biallelic LSS mutations lead to congenital hypotrichosis and cataracts, with each tissue-specific loss of function observed in mouse models.

This study identified and updated the annotation of 61 keratin genes in dogs and horses, improving the genome annotation in these species through RNA-seq data comparison.

This study found that a novel missense mutation in the vitamin D receptor caused hereditary 1,25-dihydroxyvitamin D-resistant rickets with alopecia by disrupting protein function, highlighting the importance of DNA binding in hair development.

Liposomes can make the antiandrogen RU 58841 more effective for skin application by reducing absorption, increasing skin retention, and targeting sebaceous structures.

This study found that 5% primed conditioned medium from human umbilical cord blood-derived mesenchymal stromal cells significantly improved hair density, thickness, and growth rate in patients with androgenetic alopecia.

This study found that non-thermal plasma treatment increased epidermal thickness and dermal collagen density in mouse skin tissue without causing damage, potentially promoting growth factors and tissue remodeling.

In this study, researchers administered eight sessions of intradermal injections containing growth factors into the scalp of 1000 patients, reporting a significant reduction in hair fall in 83% of participants and increased total hair count and shaft diameter, with promising tolerance and safety.
