The document concludes that using LC-MS/MS for measuring androgens is more accurate than older methods, but it needs careful validation and standardized references to be most effective.

This study describes two methods for isolating hair follicle stem cells from newborn Yangtze River Delta White Goats, highlighting differences in cell viability and marker protein expression between the methods.

This study found that inhibiting the TRPV3 channel may significantly promote hair growth and suggests a potential therapeutic approach for hair loss and related skin diseases.

This case report describes a 60-year-old woman with an ovarian Leydig cell tumor leading to elevated testosterone levels and hirsutism, highlighting the need to consider androgen-secreting tumors in similar postmenopausal cases.

This review outlines the diverse clinical presentations of cutaneous metastases in breast cancer patients and emphasizes the importance of biopsy for accurate diagnosis, but reports no new results.

This study found that all-trans retinoic acid (ATRA) negatively affects hair growth by reducing goat dermal papilla cell viability and growth factor expression.

This report describes a 20-year-old Chinese man with a rare combination of congenital compound and blue melanocytic nevus associated with alopecia areata.

This article discusses the range of skin-related side effects caused by chemotherapy and radiotherapy, including novel patterns emerging with targeted therapies, but does not report new clinical results.

The book details skin conditions in older adults, their link to mental health, cancer treatment importance, hair loss remedies, and managing autoimmune and itchy skin.

This article discusses the perspectives of clinicians and patients on alopecia areata, an autoimmune disorder with significant psychosocial impacts, highlighting the unpredictability and limited effectiveness of current treatments as well as the key unmet needs and gaps in care.

In this study, Hibiscus rosa-sinensis extract was used to formulate and evaluate herbal cosmetic creams for their antioxidant properties, stability, and effectiveness. The formulations demonstrated strong antioxidant potential, stability under various conditions, and favorable cosmetic qualities, suggesting HRS as a beneficial ingredient in skincare products.

This study developed O/W hair mask emulsions with collagen hydrolysate, keratin, and natural oils, reporting that they are stable, physiologically acceptable for skin, creamy, non-greasy, and hydrophilic, with properties suitable for cosmetic applications in hair care.

This Ph.D. project aims to evaluate the self-assembling potential of hair keratin extracts and study the cellular response to both crude and purified keratins, highlighting their potential applications from biomedical to water remediation.

This review discusses the formulations, mechanisms, and physiological aspects of hair cosmetics and types, but reports no new results, suggesting a foundation for future hair research.

This chapter classifies various benign skin tumors and discusses their characteristics, treatment indications, and potential for recurrence, but reports no new clinical findings.

This study examined the use of keratin gel as a filler in nerve guides for peripheral nerve regeneration in a rat sciatic nerve injury model.

The exam tested knowledge on various skin-related topics for CME credit.

This article reviews the current literature on rosacea, focusing on the new subtype classification system and the main theories of its pathogenesis, but reports no new clinical results.

This study developed molecular signatures for dermal papilla cells and their niche, uncovering novel signaling regulators and genes linked to hair disorders, which may inform future hair development research.

This study found that, in mouse tail epidermis, stem cells rapidly activate and regenerate new progenitors to repair wounds, with mechanisms affecting their proliferation, differentiation, and migration.

In this study, researchers found that wound healing in mouse skin recruits diverse fibroblasts, including myeloid-derived cells, which contribute to regenerating adipocytes.

This study found that autologous platelet-rich plasma increased hair growth potential by enhancing dermal papilla cell proliferation and stimulating key signaling pathways in both cell cultures and mice models.

This study found that Wnt signaling in the hair follicle is crucial for coordinating the behavior of epithelial and melanocyte stem cells, which drives hair regeneration and melanocyte differentiation in mice.

This review discusses the complex role of the immune system in tissue repair and regeneration, highlighting its positive and negative influences but reports no new clinical findings.

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.

Two main types of fibroblasts with unique functions and additional subtypes were identified in human skin.

This study found that PM2.5 exposure induced oxidative stress in human keratinocytes and mouse skin, causing cellular damage, which was mitigated by the antioxidant N-acetyl cysteine.

This study identified a distinct cytokine activation signature in alopecia areata, involving TH2, TH1, IL-23, and IL-9/TH9 pathways, suggesting potential targeting strategies similar to those in psoriasis and atopic dermatitis.

This study found that squamous cell carcinomas from hair follicle stem cells are more prone to epithelial to mesenchymal transition and metastasis than those from interfollicular epidermis, due to distinct chromatin landscapes.

This study found that Wnt signalling activates hair follicle fate in hair follicle stem cells by relieving TCF3/4–TLE-mediated repression, with β-catenin being crucial for this process.
