This study found that overexpressing human Bcl-2 in mice protected epidermal keratinocytes from UVB-induced apoptosis but unexpectedly increased apoptosis during hair follicle regression and chemotherapy.

This study found that low-dose UVB radiation enhances the survival, migration, and hair growth-promoting capacity of adipose-derived stem cells in mice through the generation of reactive oxygen species.

This study found that overexpression of PKCepsilon in mouse epidermis was associated with increased susceptibility to metastatic squamous cell carcinoma, potentially through a mechanism involving tumor necrosis factor-alpha.

In this study, researchers reported that chronic UV exposure may contribute to androgenic alopecia progression by influencing hair cycle changes and exacerbating solar elastosis in the scalp.

This study in transgenic mice found that the combination of SPF 15 sunscreen and a UVA filter provided strong protection against UVA-induced elastin promoter activation and thus may reduce photoaging.

This article reviews the impact of UV radiation and visible light on human hair structure and summarizes protective strategies, reporting no new clinical results.

This study found that UV-B exposure significantly increased the expression of inflammatory cytokines IL-1β and IL-8 in cultured sebocytes.

This review discusses environmental factors like UV radiation and smoking that affect hair health and highlights the potential role of nutrition, but it reports no new results.

This article discusses how the balding scalp's exposure to UV and near-infrared light may accelerate aging, with changes detectable under ultraviolet light; it presents no new clinical findings.

This study found that UVB radiation significantly alters miRNA expression and induces cytotoxicity and apoptosis in normal human dermal papilla cells.

This study found that ultraviolet light-enhanced visualization can detect subtle skin changes linked to carotene and vitamin A deficiency, which improved with dietary correction in deficient individuals.

This study found that UV radiation exposure increased protein elution and altered protein characteristics in hair fibers, suggesting environmental factors impact hair shaft proteins.

The researchers reported that sterol surfactants with a bulky planar structure effectively solubilized ultraviolet ray absorbers, offering a stable solution more efficiently than other surfactants.

In this study, researchers found that deleting TNFα in PKCε transgenic mice reduced the development of cutaneous squamous cell carcinomas induced by UV radiation or a chemical protocol.

In this study, PKC ε transgenic mice exposed to ultraviolet radiation showed increased hair follicle stem cell frequency and altered gene expression compared to wild-type mice, suggesting a potential role in skin cancer susceptibility.

This study reports cases of androgenetic alopecia patients with depigmented macules on sun-exposed scalp areas, suggesting potential ultraviolet-induced scalp leukoderma not covered in existing dermatology texts.

This study found that Cream 1 effectively prevented UV radiation-induced nerve ending damage in human skin samples, unlike placebo and SPF15 creams.

This study found that the immune-competent B6. Cg‐Tyr c−2J Hr hr /J congenic mouse line had a more pronounced delayed sunburn response and different proliferative skin reactions to UV exposure compared to SKH 1 mice.

In this study, ultraviolet light did not significantly enhance or worsen hair growth induced by topical minoxidil in men with male pattern baldness.

This study demonstrated that visible light lightens blond hair more effectively than ultraviolet light, attacking melanin granules directly, whereas ultraviolet light primarily damages other hair tissues following washing.

This study found that topical ginsenoside Rg1 may protect skin from UVB-induced damage in mice by reducing pathological changes and modulating cytokine mRNA expression associated with inflammation and immune response.

This article proposes that androgenic alopecia might be an evolutionary mechanism for reducing prostate cancer risk by enhancing UV absorption, rather than being a risk factor.

In this study, UVB exposure was found to alter certain chemical properties of the hair shaft, such as keratin components and water content, without significantly affecting its physical morphology.

This study investigated the effects of UV rays and particulate matter on hair porosity, finding that UV exposure increased porosity over time, and when combined with particulate matter, this effect was significantly enhanced in bleached hair.

This article discusses the multifactorial nature of acne, including its association with follicular hyperkeratosis, sebaceous lipids, Propionibacterium acnes, and perifollicular inflammation, but reports no new clinical findings.

This study found that overexpression of PKCɛ in mouse epidermis increased sensitivity to metastatic squamous cell carcinoma, suggesting that a PKCɛ-mediated microenvironment may promote cancer development through specific cytokines like TNFα.

This study found that phenylbutazone and fluocinolone acetonide have similar anti-redness effects in both haired and hairless animals, making hairless rats a potential alternative for testing without needing depilation.

In this observational retrospective study, UVF-dermoscopy was found to be more effective than polarized dermoscopy in identifying follicular features and distinguishing between scarring and nonscarring alopecias, particularly in individuals with lighter skin tones.

Combining UV therapy with PRP heals chronic wounds faster and reduces pain.

This study found that caffeic acid reduced UVB-induced damage and oxidative stress in human dermal papilla cells, suggesting its protective efficacy against such cellular damage.
