This research found that translucent keratin films absorbed more dye than opaque films, suggesting they may serve as better screening substrates for evaluating hair dye effectiveness.

This study found that in mouse melanocytes, the cytoplasmic dynein complex component Dynlt3 is necessary for proper melanosome transport, acidity regulation, and effective transfer to keratinocytes, linking it to skin pigmentation processes.

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

In this in vitro study, pretreatment with Dead Sea water and saline magnetized water reduced UVB-induced DNA damage and inflammation markers in human keratinocyte cells, primarily through autophagy activation, suggesting potential use in topical products to prevent skin damage from UV exposure.

This article discusses the use of forensic DNA phenotyping to infer physical characteristics from biological samples without a reference sample, aiding investigations but raising ethical and legal concerns.

UV-enhanced trichoscopy helps diagnose hair shaft disorders like pili annulati.

This study found that using a microscope can effectively distinguish between human and animal hair based on microscopic characteristics, making it a critical tool in forensic investigations.

This review discusses the effectiveness of non-thermal, non-ablative devices like light-emitting diodes in treating various skin and hair conditions but reports no new clinical findings.

This study identified three patient groups based on the psychological and social impact of vitiligo, with the most affected group experiencing severe psychosocial burdens despite often having mild physician-reported disease severity.

Basal cell carcinoma mostly starts from cells in the upper skin layers, not hair follicle stem cells.

This study found that photoexposure significantly increased the gene expression of altered elastin, MMP12, and LOX, as well as the protein expression of tropoelastin and fibrillin-1, in skin models.

This review highlights how the development of forensic DNA phenotyping systems like IrisPlex, HIrisPlex, and HIrisPlex-S has advanced criminal investigation by accurately predicting physical traits such as eye, hair, and skin color from DNA, thereby improving the precision and relevance of forensic applications.

This study synthesized silver nanoparticles using an Artocarpus heterophyllus leaf extract and found that these nanoparticles, with a size of 100–110 nm, displayed effective antioxidant, antibacterial, and antifungal activities in vitro.

This systematic review provides an in-depth evaluation of non-invasive imaging and biophysical methods for diagnosing and monitoring vitiligo, emphasizing the need for studies with larger sample sizes to verify their use in clinical practice and research.

This review discusses the potential of ultraviolet (UV) radiation technologies in wound care, highlighting their antimicrobial properties and risks of DNA damage, but reports no new clinical findings.

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.

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.

This study observed that testosterone concentrations in hair segments show some stability over time, but are influenced by factors like sebum integration, hair washing frequency, and individual hair growth rates.

This study found that hair testosterone concentrations show some consistency over time, but factors like hair washing and individual growth rates influence these levels, suggesting the need for careful sampling and analysis adjustments.

In this study, researchers identified 32 differentially expressed genes involved in androgenetic alopecia, with down-regulated genes associated with Wnt and TGF-beta signaling and up-regulated genes linked to oxidative stress pathways.

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 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 study revealed that photobiomodulation significantly improved hair density in androgenetic alopecia patients, with laser treatments being more effective than combined laser/LED treatments, while device style did not significantly affect outcomes.

This study suggests that using UVFD to examine non-pigmented facial lesions can potentially enhance diagnostic accuracy and reduce unnecessary biopsies.

Cromolyn sodium's effectiveness for treating asthma in children under 2 is unclear, possibly more beneficial for older children, and further research is needed.

This review discusses the effects of visible light on human skin, highlighting its role in pigmentation, thermal damage, and the treatment of several skin conditions, while noting limited sunscreen protection against it; no new clinical results are reported.

In this study, researchers used scanning electron microscopy to analyze hair damage from 3% hydrogen peroxide and UVB radiation, observing that Caesalpinia sappan hair tonic formulations coated and interacted with the hair cuticle, potentially modifying hair fiber damage.

This review found that among emerging technologies for skin anti-aging, stem cell therapies using recipient chimerism might be more beneficial than CRISPR-Cas9 and other current innovations, though further studies on safety and efficacy are needed.

This study found that both genetic and epigenetic factors significantly influence age-related facial skin aging, with lifestyle and environmental factors also playing a substantial role.

This review reports that certain chemical ingredients in cosmetics are linked to various health issues, including cancer and reproductive disorders, and highlights concerns about their safety, advising careful selection and use to mitigate potential risks to human health.
