This study found that activin B promotes the initiation and development of hair follicles in both cultured and neonatal mouse skin models.

This study found that consuming 100 mg of pea sprout extract daily for 8 weeks significantly reduced hair loss in individuals experiencing excessive hair shedding.

Nutricosmetics with active ingredients can help with hair loss and improve hair growth.

This case study identified low iron stores, potentially linked to heavy menstrual periods, as a trigger for diffuse nonscarring alopecia in a 31-year-old woman, leading to a diagnosis of telogen effluvium, for which iron supplementation was prescribed.

This review highlights several natural ingredients, including Citrus Sinensis, Nigella sativa, flax seed, and coconut oil, that may promote hair growth and prevent hair loss due to their protective and nourishing properties, focusing on their formulation into hair serum.

Intermittent iron and nutritional supplements can help reduce hair loss.

This study identified new dietary ligands for the human vitamin D receptor, including curcumin and gamma-tocotrienol, which may influence its biological functions.

This review discusses the development of the MATH+ treatment protocol for COVID-19 patients, detailing its scientific and clinical rationale, but reports no new experimental findings.

This study observed that gerbils exhibit a different wound healing mechanism compared to mice, with lower TGF-B1 expression and distinct tissue responses, yet achieve similar healing outcomes.

This review highlights that both human-derived and plant-derived exosomes show anti-inflammatory and antioxidant properties, with human exosomes being better for targeted medicinal treatments due to their ability to transport healing drugs, while plant exosomes are more scalable and cost-effective for cosmetic applications.

This study reports that familial frontal fibrosing alopecia was diagnosed earlier in premenopausal women compared to postmenopausal women, though long-term outcomes remain uncertain without a definitive treatment.

This study found that differentiated airway epithelial cells can revert into functional stem cells in vivo, suggesting a more general role for this dedifferentiation process in tissue regeneration in higher vertebrates.

This study developed molecular signatures for dermal papilla cells and their niche, uncovering novel signaling regulators and genes linked to hair disorders, which may inform future hair development research.

This study suggests that skin-derived precursors from Sox2(+) hair follicle dermal cells have the potential to function as dermal stem cells, supporting hair morphogenesis, dermal maintenance, and wound-healing.

In this study, homozygous VDR null mutant mice exhibited nonfunctional vitamin D receptors, leading to growth abnormalities and revealing the limited physiological importance of vitamin D pathways outside the classical receptor.

This study found that altering cell culture conditions to form three-dimensional papilla spheroids can restore the ability of human dermal papilla cells to induce hair growth in adult skin.

This study demonstrated that stress-derived neurosteroid THDOC shifts from inhibiting to activating the HPA axis under stress, presenting potential therapeutic targets for stress-related disorders.

This review discusses the various treatment options for male and female pattern hair loss and provides no new clinical results; the authors outline the most effective strategies based on existing evidence.

This study explored the effectiveness of the oral JAK1/2 inhibitor ruxolitinib in treating patients with moderate-to-severe alopecia areata, building on prior success with JAK inhibitors in mice, but results are not reported in this abstract.

This review discusses skin-related toxicities associated with targeted cancer therapies and emphasizes the need for dermatologists to understand and manage these adverse effects, but reports no new experimental results.

This study found that TRPV1 activation in human scalp hair follicles inhibited hair shaft elongation, suppressed proliferation, and induced apoptosis, suggesting TRPV1 as a potential target for managing hair growth and epithelial disorders.

The researchers reported that DHT-inducible DKK-1 may play a significant role in DHT-driven balding by inhibiting hair follicle cell growth and promoting apoptosis in androgenetic alopecia.

This review outlines the various processes activated by the peptide GHK-Cu in tissue remodeling and reports improvements in skin and wound healing but notes a need for further study to fully understand these mechanisms.

This study found that modulating BMP activity in transgenic mice affects the development and characteristics of several ectodermal organs, such as skin, hair, and claws, highlighting a stage-dependent influence on organogenesis.

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 study shows that macrophage-induced TNF signaling can activate hair follicle stem cells and promote new hair follicle formation after wounding by regulating AKT/β-catenin pathways.

This study reports previously unrecognized cellular complexity in growing mouse incisors, suggesting species-specific differences in cell dynamics between mouse and human teeth related to growth and differentiation.

This study observed that the ontogenetic transition from scarless repair in early fetal rat wounds to scar-forming repair in late gestation is associated with differential TGF-β ligand and receptor expression patterns.

This study found that the vitamin D receptor in lampreys, which lack bones and hair, binds 1,25-dihydroxyvitamin D3 and may function to induce enzymes for detoxifying substances.

This study found that human hair follicles express ATP-sensitive potassium channels, suggesting that minoxidil acts on these channels and that drugs targeting them may treat hair disorders.
