This review examines the skin exposome, including solar exposure, air pollution, hormones, nutrition, and psychological factors, but reports no new clinical results.

This study found that the EpiLight Hair Removal System achieved approximately 60% hair removal after 12 weeks following a single treatment, indicating effectiveness and safety for long-term hair reduction.

Tiny particles carrying roxithromycin can effectively target and deliver the drug to hair follicles without irritation.

This study found that Twist1 and Tcf4 synergistically regulate the hair follicle induction ability of dermal papilla cells by forming a complex with β-catenin, enhancing their biological properties.

Validated method reliably measures finasteride in tablets using liquid chromatography.

This study demonstrated that dyeing can enhance the absorption coefficient of hair follicle tissues for selective photodestruction within human skin and hair follicles.

In this study, Epimedii Folium extract was found to enhance melanin production and promote pigmentation through mechanisms involving the MAPK/ERK1/2 pathway in both in vitro and in vivo models.

In this study on C57BL/6 mice, researchers found that cadmium chloride exposure led to metabolic disruption, accelerated skin aging, and impaired hair regeneration, with more severe effects observed at higher doses.

This study found that the purified compound VB1 from Vitex negundo seeds may reduce UVA-induced skin aging by targeting MAPK1 and demonstrated its potential in mice.

Using a CO₂ laser for hair transplants improves the surgery and may become important in future hair restoration.

This study found differences in melanin content and gene expression in skin under black and white hair of giant pandas, providing a basis for further research on hair color distribution and skin diseases.

Any drug can cause skin reactions, but antibiotics, NSAIDs, and psychotropic drugs are more common, with some reactions being life-threatening.

In this animal study, researchers found that exposure to a CO2 laser at various power levels caused significant skin damage in rats, including severe burns, coagulation, and tissue obliteration, with higher laser doses resulting in more pronounced injuries.

This study found that high-speed optical coherence tomography may be a promising non-invasive tool for analyzing human hair conditions.

This review discusses the application of low-level light therapy for hair loss treatment, particularly androgenetic alopecia, and reports no new clinical results; the authors suggest consideration of light source characteristics and potential pros and cons.

This study found that increasing a drug's lipophilicity and adding ethanol to the donor phase can enhance its delivery to the hair follicle, although the precise transport mechanism remains unclear.

This systematic review found that toluidine blue may be valuable for diagnosing and treating specific skin tumors in the context of Mohs micrographic surgery, though literature on its use is limited and mostly qualitative.

This article discusses the diagnostic challenges between certain neonatal scalp conditions and highlights the potential of line-field confocal optical coherence tomography to provide detailed, non-invasive skin examination, without presenting new clinical findings.

Environmental, chemical, mechanical, and personal health factors can all damage hair and contribute to hair loss or changes in hair quality.

This review concluded that LED-based photobiomodulation is generally safe and effective for certain dermatologic conditions, though consumer devices often show less efficacy compared to professional systems.

This study found that the HairMax LaserComb® significantly increased hair density and was safe and well tolerated for treating androgenetic alopecia in men compared to a sham device.

This study found that anagen-phase hair follicles in mice are particularly sensitive to damage by ruby laser pulses, resulting in alopecia without scarring, suggesting enhanced laser hair removal strategies.

Treatments for melanin disorders exist, but more effective options needed.

This study found that deleting Stim1 and Stim2 in mature T regulatory cells disrupts Ca 2+ signaling, preventing their differentiation and leading to severe autoimmune disorders in mice.

This review discusses five popular resurfacing technologies for facial rejuvenation, highlighting their role in achieving smoother, healthier, and younger-looking skin, and reports no new clinical results.

This study concluded that low-level fluence 810 nm diode laser therapy was generally well tolerated, safe, and effective for long-term hair reduction in a small sample of patients with various skin types.

In this study, researchers observed that quiescent mouse embryonic fibroblasts showed reduced glycolysis but increased TCA cycle flux and mitochondrial respiration, with these changes linked to metabolic reprogramming involving yes-associated protein inhibition and malate cycle modulation, which supports extracellular matrix protein synthesis.

This review reports that natural compounds show promise in slowing skin photoaging by targeting cellular pathways in keratinocytes and fibroblasts. However, comprehensive clinical studies are needed to verify their efficacy and safety.

This study found that Eclipta alba extracts exhibit significant antimicrobial activity against various human pathogens, including antibiotic-resistant strains, suggesting potential use in treating infectious diseases.

The researchers observed that normal murine hair follicles are direct targets for melatonin, with receptor expression varying throughout the hair cycle, suggesting melatonin's role in hair cycle control.
