In this study of C3H/HeJ mice, researchers observed that alopecia areata is associated with the expansion of exhausted-memory CD8 T cells in multiple organs, with autoreactive activation not fully explained by known mechanisms, shedding light on the immunological dynamics underlying the condition.

TS-SCLF from fermented Schisandra chinensis may promote hair growth and improve hair quality.

This study evaluated an 808-nm diode laser at different fluences for permanent axillary hair removal in Korean women and found that high-fluence treatment (14 J/cm2) effectively reduced hair density and thickness, with no significant difference in comfort compared to lower fluences.

This case report describes severe myelosuppression and alopecia totalis in a 10-year-old boy after azathioprine treatment for IgA nephropathy, which resolved after stopping the drug and receiving granulocyte colony-stimulating factor.

In this study, researchers found that neonate hairs have a distinct microstructure with no medulla and smaller hair follicles compared to adult hairs.

This study found that Grateloupia elliptica extract may promote hair growth by activating wnt/b-catenin signaling and enhancing dermal papilla cell proliferation in rat and mouse models.

This study found that several small molecule peptides based on thymosin β4 significantly promoted cell proliferation related to wound healing, angiogenesis, and hair growth more effectively than established positive controls.

This study found that Clitocybin A from Clitocybe aurantiaca significantly increased the proliferation of immortalized rat dermal papilla cells, suggesting potential hair growth-promoting effects in a laboratory setting.

This study demonstrated that injecting reconstructed dermal papilla-like tissues in mice led to new hair growth, suggesting potential future applications in hair transplantation and baldness treatment.

This study found that improved nutritional status after gastric cancer surgery was associated with better quality of life, with malnourished patients experiencing greater eating restrictions, anxiety, and other issues.

This study found that an anti-atopic lotion containing fucoidan helped heal skin damage in hairless mice with atopic dermatitis by reducing skin thickness and modulating immune responses.

This study suggests that Orostachys iwarenge extract may promote hair growth by increasing the proliferation of dermal papilla cells in an in-vitro setting.

This study found that in androgenetic alopecia patients, there is enhanced expression of type 2 TGF-β and type II receptors in hair follicles, suggesting a link to hair growth cycle changes.

This study found that over-expression of thymosin beta-4 in transgenic mice accelerated wound healing and hair growth, but did not affect tumor progression despite stimulating tumor metastasis.

This study reported a case of a 34-year-old male developing allergic contact dermatitis to minoxidil solution, with positive patch test reactions attributed to the solution's ingredients, highlighting the potential for propylene glycol sensitivity.

This research found that topical minoxidil may promote hair regrowth in alopecia areata by stimulating hair follicle epithelium and suppressing certain immune responses, with potential contributions from its vasodilatory effects.

This study found that Cnidium officinale extract and its compound ferulic acid improved hair growth by promoting dermal papilla cell function and mitochondrial activity, suggesting their potential as a new treatment option for alopecia, possibly through estrogen receptor alpha activation.

This study reported that a new coating made with delaminated Ti₃C₂ MXene nano-sheets and a tea-derived compound effectively protects hair keratin from damage by providing UV screening, thermal dissipation, and antioxidation, while also enhancing mechanical strength and restoring wettability.

This study reported that abietic acid, derived from pine rosin, showed antimicrobial effects and reduced biofilm biomass in laboratory tests against microorganisms like Staphylococcus aureus and Candida albicans, suggesting potential further applications for skin infections.

In this study, oral administration of ginsenoside Rf from Panax ginseng promoted hair regrowth and increased hair thickness in a mouse model of androgenetic alopecia by enhancing androgen receptor degradation, highlighting its potential for cosmetic and functional food applications.

In this case study, individualized classical homeopathy was reported to effectively promote significant hair regrowth and improve emotional stability in a patient with alopecia areata, showcasing a potential holistic and sustainable alternative to conventional treatments.

In this experimental study, the researchers observed that Platycladus orientalis leaf extract promoted hair growth by enhancing dermal papilla cell proliferation and increasing growth factor expression, particularly through ACK1 activation and modulation of Wnt/β-catenin signaling pathways in cultured human cells and a 12-week topical application.

This study found that oral administration of solubilized sturgeon oil in mice promoted hair growth and positively influenced the gut microbiome associated with hair growth promotion.

This article discusses the clinical and histological features of alopecia areata, a T-cell-mediated autoimmune disorder causing unpredictable nonscarring hair loss, without providing new clinical findings.

In this study, researchers reported three cases of alopecia areata patients experiencing a rare targetoid pattern of hair regrowth, a phenomenon originally described in 1988.

This study found that HtrA2 inactivation in mnd2 mice is associated with delayed hair cycle phases and growth retardation of adipocytes, suggesting HtrA2's role in regulating adipogenesis-related hair growth.

This study found that activating both PKM2 and Wnt/β-catenin signaling enhanced hair re-growth and HFSCs proliferation in mice, suggesting a potential treatment strategy for alopecia.

This review explores dermatological manifestations and cutaneous drug reactions associated with COVID-19, providing insights for clinicians on recognizing these signs and understanding their potential mechanisms, but it reports no new clinical results.
