This study assessed three materials—L-arginine, hydrolysed keratin, and cystine-silanol copolymer—ex vivo for their potential to reduce undesirable effects of hair bleaching, such as damage to hair proteins.

A 90-year-old woman's hand lesion was a rare, aggressive skin cancer treated successfully with surgery.

This article discusses the biology of cosmetic aging and the chemical pathways involved, emphasizing research advancements that aid clinicians in rejuvenating skin and increasing scalp hair density, but it provides no new results.

This study found that electrical epilation in organ-cultured human scalp skin perturbs hair follicles by causing inflammation, impairing melanin production, and possibly inhibiting post-epilation hair re-growth.

This study found that ERBB2 mutations and amplifications are likely key drivers of extramammary Paget disease, suggesting potential for targeted therapies and cancer immunotherapy due to the moderately high mutational load observed.

This study found that Basonuclin 1 knockdown in human primary keratinocytes significantly reduces cell proliferation and affects migration, indicating its role in coordinating the re-epithelization phase of wound healing.

This study found no significant association between metabolic syndrome and lichen planus, but hypertension, triglycerides, and low HDLC levels were significantly associated with lichen planus.

This study observed that hair follicle cuticular cells undergoing keratinization were significantly thicker than those in a normal hair shaft, due to incomplete loss of cytosol.

This study suggests that enhancing endocannabinoid tone with an EMT-inhibitor may have anti-inflammatory effects and slightly increase sebaceous lipid production, which could be beneficial for dry skin conditions.

In this study, researchers found that neonate hairs have a distinct microstructure with no medulla and smaller hair follicles compared to adult hairs.

This study reports that cannabinoid receptor type 1 may influence psoriasis development by modulating laminin-511 expression, suggesting a potential target for treatment.

This study suggests that the phenotype of melasma in women is influenced by structural and cellular changes across the epidermal-melanin unit, not just melanocyte hypertrophy, highlighting potential roles for dermal damage repair and fibroblast senescence.

This article discusses the role of inflammation in causing various types of alopecia but reports no clinical results; the author notes an ongoing interest in the topic.

This study found that inserting isolated hair follicle units into engineered dermis promoted differentiation and maturation of tissue-engineered skin, maintaining hair follicle morphology and generating skin appendages like sebaceous glands.

This study found that chronic administration of finasteride in rats led to significant alterations in the epididymis and compromised sperm quality, effects that persisted even after 30 days of treatment cessation.

This study concluded that the expression of specific glycoconjugate terminal sugars is developmentally regulated during rat hair follicle morphogenesis.

This study found that mouse hair follicle stem cells use symmetric cell division for maintenance and fate determination, and identified Gata6 as a crucial factor for their differentiation.

Activating cAMP and ATP improves hair growth and strength.

This study found that Danthron induced apoptosis in a human malignant melanoma cell line through mitochondrial, endoplasmic reticulum, and death receptor pathways.

This study found that normal murine hair follicles are direct targets for melatonin bioregulation, expressing receptors that are regulated in a hair cycle-dependent manner, influencing keratinocyte apoptosis.

In this study, patients with systemic lupus erythematosus and generalized non-scarring alopecia exhibited hair loss similar to telogen effluvium, with significant changes observed in the cuticle of telogen hairs.

This microscopy study examined the non-keratinous regions of human hair fibers, revealing detailed morphology that could help understand how external influences affect hair structure.

This study suggests that holes found in mature hair fibers may be linked to daily hair care actions and the removal of extractable substances.

This study reported that dandelion herb-derived carbon dots significantly enhanced wound healing in mice with Staphylococcus aureus infections, outperforming a commercial wound healing spray through their antibacterial and dual ROS-modulating capabilities.

Skin organoids can regenerate hair by forming specific cell units with certain signals.

Platelet-rich fibrin is becoming popular for medical and cosmetic uses like hair growth and natural fillers.

This article outlines a detailed framework for taking dermatological history and examination, emphasizing the importance of considering various factors like medication and occupational history; it reports no new clinical findings.

This review summarizes the clinical characteristics of Behcet's disease, noting that ocular manifestations are a major cause of morbidity due to their potential to lead to severe vision loss or blindness.

This study suggests that human hair follicle cells and epidermal keratinocytes differ in their degree of keratinization and other characteristics when cultured on mixed collagen membranes.

In this study, certain Chinese herbal medicines were found to significantly stimulate or inhibit hair growth in an in vitro organ culture model of mouse vibrissa follicles.
