This study compared the protective effects of two conditioners, Protective factor C and Keratin, on hair damaged by perm treatment using a model of damaged hair.

This study found that mesenchymal stem cell-derived exosomes reduced hearing and hair cell loss caused by neomycin in experimental models by modulating autophagy, which promoted cell survival and lowered oxidative stress and apoptosis, indicating potential for deafness treatment.

In this study, a superoxide dismutase gel prevented hair graying in mice exposed to photosensitization, suggesting that antioxidants can protect against oxidative damage involved in hair aging.

In this study, intranasal delivery of hair follicle-derived stem cells improved neurological function and reduced brain damage in a rat model of ischemic stroke.

This study suggests that combining 17-beta estradiol with prednisolone could accelerate hair regrowth after chemotherapy-induced alopecia in humans, based on preclinical findings using an in vitro model.

This chapter discusses the skin stem cell niche as a complex ecosystem and highlights the diverse components and interactions that influence stem cell function, but it reports no new experimental results.

The book provides updated methods for skin research and treatment.

This study developed mathematical models showing that heat penetrates individual hair quickly but takes longer to reach the center of hair bundles, helping understand potential damage from high-temperature styling tools.

In a mouse model study, researchers observed that the absence of MCPIP1 in myeloid cells decreased susceptibility to chemically induced skin papillomas but caused significant hair loss and skin pigmentation changes, suggesting a role for MCPIP1 in skin carcinogenesis and follicle integrity.

In this study, researchers observed that epidermal damage may increase susceptibility to Bacillus anthracis infection, allowing it access through hair follicles and the denuded dermis in mice.

This study found that, while hair follicle bulge stem cells are important for hair follicle survival and epidermal regeneration after wounding, the epidermis maintains itself independently of these cells under normal conditions.

This study highlights multiple factors contributing to hair graying, such as oxidative damage, melanocyte changes, and genetic influences, and suggests that repigmentation may be temporarily reversible, offering potential targets for future treatments while urging caution when applying mouse model findings to humans.

This study's simulations suggest that replenishing free 18‐MEA could restore damaged hair surface properties, highlighting the importance of optimal fatty acid spacing for maintaining hair integrity.

This review discusses the use of zebrafish larvae as an alternative model for studying ototoxicity, facilitating large-scale screening for otoprotective compounds, but reports no new clinical results.

This study found that organ-cultured human scalp hair follicles can mimic chemotherapy-induced damage in vivo and serve as a model to explore molecular targets and protective agents for hair follicle preservation.

This study observed that regular coconut oil users have significantly reduced hair irregularities compared to non-oil users, as quantified by a new "hair protection factor" metric, highlighting coconut oil's potential in minimizing hair damage.

This study found that red ginseng oil may enhance hair growth and protect skin from UV damage in mouse models by promoting regenerative processes and reducing inflammation.

This study established an experimental model to visualize calcium ion distribution after skin barrier damage in canine epidermis, observing that calcium gradients changed differently depending on the type of damage and time elapsed.

BrdU speeds up hair follicle aging and reduces hair quality.

This study found that keratin film from human hair samples responded to damage from UV, bleaching, perming, and thermal treatments, making it a useful model for evaluating hair damage in product development.

This study demonstrated that a new non-invasive method for collecting and analyzing mouse hair follicles could replace traditional biopsy methods, providing advantages for translational research and routine applications.

This study reported that peanut callus extract, rich in resveratrol, significantly stimulated hair growth and reduced hair loss in an in vitro model and a clinical trial, showing promise as a cosmetic bioactive ingredient.

This study explored the effects of DPP, a 15-PGDH inhibitor, on human follicle dermal papilla cells damaged by dihydrotestosterone and observed that DPP enhanced wound healing, reduced reactive oxygen species, and increased hair growth in ex vivo human hair follicle cultures.

This study found that transplanting trichogenous dermal cells significantly enhanced the restoration of in vivo-damaged hair follicles in a nude rat model, with a combination of dermal papilla and sheath cells proving more effective than either cell type alone.

This study developed a dissolvable microneedle system delivering specific molecules to remodel lymphatic networks and normalize metabolic processes, which accelerated hair growth and activated hair follicle stem cells in a mouse model of androgenetic alopecia.

This study found that near-infrared LED therapy enhanced ATP synthesis, reduced reactive oxygen species, and promoted collagen production and hair growth more effectively than white LEDs in human skin cells and a photoaging mouse model.

This review discusses the pathobiology of chemotherapy-induced alopecia and highlights challenges in managing it, reporting no new clinical results and emphasizing the need for well-designed preclinical models to develop effective treatments.

17-β estradiol and prednisolone may speed up hair regrowth after chemotherapy.

This study found that topical EGF-liposomal solution may protect hair follicles from chemotherapy-induced damage by inducing a catagen-like stage in a mouse model.

This study established a mouse model of atopic dermatitis with overgrowth of Malassezia globosa using olive oil as a vehicle, which caused severe lesions and hair follicle damage.
