This study developed a mathematical model to explore hair follicle regeneration mechanisms, showing that low spontaneous apoptosis rates help regenerate hair follicles after ionizing radiation, while high rates lead to degeneration during the catagen phase.

This study found that shikimic acid- and maleate-based hair repair agents modified the structure of hair fibers, though they did not increase disulfide bridge content in the hair cortex.

This study found that both everyday physical and environmental stresses, as well as chemical treatments, contributed to hair damage, with cuticle layers being more noticeably affected.

In this study, photodynamic therapy was found to achieve permanent reduction of nonpigmented hair in mice, unlike an 800-nm diode laser, by targeting the hair matrix through repeated sessions.

This study found that down-regulation of sonic hedgehog gene expression is a critical early event in chemotherapy-induced tissue damage in hair and feather follicles.

This study found that applying superoxide dismutase (SOD) gel on mice protected against hair graying caused by UV-A and psoralen exposure, suggesting photosensitization may be a factor in hair aging.

This review discusses the benefits of non-denatured soybean extracts in skincare, suggesting potential roles in skin lightening, anti-aging, delaying hair growth, and photoprotection, but it reports no new clinical results.

This study suggests that hair follicle mesenchymal stem cells may alleviate small intestinal ischemia-reperfusion injury in rats by promoting angiogenesis, reducing apoptosis, and enhancing intestinal stem cell expression.

Minoxidil rejuvenates hair follicles and reduces aging signs in male pattern baldness.

This study suggests that hair follicle mesenchymal stem cells may alleviate small intestinal ischaemia-reperfusion injury in rats by promoting angiogenesis, reducing apoptosis, and protecting intestinal mucosal function.

This study suggests that hair follicle-derived mesenchymal stem cell transplantation may effectively treat acute pancreatitis by reducing inflammation and promoting pancreatic regeneration in a rat model.

This study used molecular dynamics simulations to illustrate the complex molecular behavior of the hair surface F-layer, highlighting how fatty acids interact with 18-MEA under different conditions.

This study demonstrated that keratin derived from human hair can improve axon extension and alleviate motor deficits from sciatic nerve injuries, highlighting its potential as a promising biomaterial for peripheral nerve regeneration.

In this in vitro study, red ginseng extract and its main ginsenoside, G-Rb1, were found to protect human hair follicular keratinocytes from oxidative damage, preventing apoptosis, promoting hair growth, and modulating hair cycle transitions by influencing specific cellular signaling pathways.

In this study, researchers found that alkylating chemotherapy causes hair follicle stem cells to lose their regenerative ability by initially triggering proliferation followed by apoptosis, leading to permanent regeneration loss.

This study developed and validated a computational model to optimize skin precooling methods for minimizing thermal damage during laser procedures.

A new method helps understand hair shine and various products improve hair care.

Keratin film can effectively mimic human hair for testing hair damage.

This review examines mechanical and chemical causes of hair fiber adhesion failure and fracture patterns in the cell membrane complex, but presents no new experimental results.

In this study, a taurine-based ionic liquid was developed to effectively penetrate the skin barrier and deliver antioxidants to hair follicles, reducing oxidative stress and promoting hair regrowth in an androgenic alopecia animal model.

This study found that ethanolic extracts of Microsechium helleri showed notable antioxidant, hypoglycemic, and cardioprotective activities, while chloroformic extracts exhibited significant anti-inflammatory effects in experimental models.

This study found that Mdm2 is critical for limiting p53 activity to maintain normal stem cell function in mouse skin, with impacts on tissue homeostasis and aging.

This study found that topical resveratrol significantly promotes hair growth in mice and may protect human dermal papilla cells from oxidative damage, suggesting its potential as a treatment for hair loss.

This study found that a combination of botanical extracts from Pisum sativum and Salvia hispanica reduced oxidative damage, re-balanced scalp oiliness, and improved scalp hydration and barrier function after pollution exposure.

This study found that hepatic KRT79 expression is regulated by PPARA and is significantly associated with liver stress, suggesting it may serve as a diagnostic marker for liver diseases.

This study reported that albino Wistar rats exposed to chemical hair straighteners showed significant hair fiber damage and scalp skin deterioration, which worsened with repeated and prolonged application, highlighting the cytotoxic potential of these products and potential systemic risks.

This paper discusses the use of Digital Volumetric Imaging with fluorescent dyes to visualize and compare the interior structures of six different virgin hair types, reporting no new clinical results.

This research found that Foxc1 transcription factor and COL17A1 are critical in regulating quiescence and hair thinning in hair follicle stem cells, with aging-related DNA damage leading to hair loss.

This study discovered that the circadian clock influences hair follicle regeneration, making hair grow faster in the morning and causing more radiation-induced hair loss in the morning compared to the evening.

This study found that natural tea trichomes accelerated wound healing and provided photoprotection in a mouse model, suggesting potential as a sustainable biomaterial for skin repair due to its antioxidant properties and ability to enhance tissue regeneration and reduce UV-induced skin damage.
