The document explains what healthy skin, nails, and hair look like on an ultrasound.

This review highlights the potential of microneedles as a low-cost, well-tolerated method for transdermal drug delivery in dermatology, though further research is needed to establish their clinical efficacy.

This study evaluated a novel synthetic cell-penetrating peptide, DualPep-ALO, finding it promotes hair growth by enhancing follicle cell proliferation, activating regenerative pathways, and reducing inflammation and oxidative stress in vitro and ex vivo, suggesting a promising new topical treatment for hair loss that rivals minoxidil.

This study reviews prior research using transgenic K6/ODC mice and demonstrates that elevated polyamines in epithelial cells contribute significantly to skin tumor development and progression by stimulating proliferation, altering cell signaling and chromatin remodeling, and affecting immune functionality, amongst other mechanisms.

In this study, researchers found that sesamin, a component of sesamum, modulated the AR-MAPK-Wnt signaling pathway in DHT-stimulated HaCaT keratinocytes, demonstrating potential multi-target activity against molecular events in androgenetic alopecia.

In this systematic review, animal studies showed that cytarabine causes multi-organ toxicities, notably neurotoxicity, linked to oxidative stress and other mechanisms, though study quality raises concerns about reliability and translation to human outcomes.

Scarring alopecia involves increased immune cells and specific gene changes near damaged hair follicles.

In this research, scientists developed a compression therapy model using immobilized mice, successfully analyzing skin without causing injury, and observed increased epidermal thickness and changes in adipocyte volume, with no increase in DNA damage markers.

Cell movements and forces shape feather growth in chicken skin.

This study examines the historical and current development of cancer registries, highlighting their pivotal role in understanding and managing skin cancer, particularly noting improvements in the data quality of nonmelanoma skin cancers since 2013.

This review discusses the unmet needs and barriers in managing alopecia areata in Latin America, highlighting access constraints and recommending coordinated efforts to improve patient outcomes with promising new treatments.

This review discusses the potential of the hair follicle dermis to direct hair development and explores concepts related to hair growth and androgenetic alopecia, without reporting new clinical results.

Some breast cancer treatments caused long-term hair loss in women, similar to a condition called alopecia areata.

This review discusses the mechanisms of wound-induced hair neogenesis and its similarities with embryonic hair follicle development, but reports no new clinical results.

This study found that the TrichoScan effectively measures hair growth changes, showing significant increases in hair counts and thickness in men with androgenetic alopecia after 6 months of using 5% minoxidil solution.

This article discusses stem cell-based therapies for wound healing and highlights their potential for tissue repair and regeneration, without presenting new clinical results.

This study found that island grafting in guinea pigs enabled the isolated study of early skin regeneration processes, distinguishing them from natural wound closure mechanisms like epithelialization and contraction.

This study discovered that adipose tissue infiltration at the isthmus level appears significantly more often in frontal fibrosing alopecia cases compared to controls, suggesting a potential role in the condition's pathology.

This case series reports that home use of intense pulsed light devices may effectively reduce hair burden and prevent recurrence of pilonidal disease in patients unable to regularly attend clinic sessions.

This case report describes a rare instance of sebaceous trichofolliculoma identified in an 18-year-old boy, characterized by a dermal nodule on the nasal bridge with distinct histological features.

This study details the presence of two types of cysts in rhino mouse skin, with utricles derived from hair canals and deeper cysts from hair root sheath epithelium.

This study observed that nicotinamide can effectively inhibit human hair growth and promote hair follicle regression in cultured human scalp models without negatively affecting epidermal vitality, suggesting its potential as a hair growth inhibitor in cosmetic applications.

This report describes a case of a 4-year-old boy diagnosed with linear alopecia areata, characterized by patchy hair loss and associated with unique hyperpigmented skin lesions.

This review discusses the roles of key epithelial-mesenchymal transition factors and potential therapeutic opportunities involving cancer metabolic pathways, reporting no new clinical results.

This study reported that the most common skin side effect of epidermal growth factor receptor inhibitors was a papulopustular rash, treatable with symptom-targeted therapies, while drug suspension was rarely needed.

This study found that Puerariae Radix ethanol extracts increased the proliferation of human hair dermal papilla cells via ERK and Akt phosphorylation, suggesting potential benefits for alopecia treatment.

This study found that melatonin enhanced whisker growth in vitro and identified MT1 receptor presence in the granular layer of mouse epidermis and the outer root sheath, suggesting potential for hair growth treatment.

This study reviewed the epidemiology and treatment of inflammatory cicatricial alopecias and highlighted the importance of scalp biopsies for accurate diagnosis in a mixed ethnic population at a university hair clinic.

This review examines the epidemiology, pathophysiology, diagnosis, and management strategies for non-classic congenital hyperplasia due to 21-hydroxylase deficiency, and provides evidence-based recommendations for its treatment and genetic counseling.

This study found weak epidemiological associations between male pattern baldness and coronary heart disease, but no significant genetic link, though specific loci shared risks with other conditions.
