This study introduced laser-assisted exosome delivery and observed early signs of clinical improvement in two patients, though causality cannot be inferred from these preliminary, uncontrolled cases.

This report documents a 14-year-old Chinese boy with mitochondrial encephalopathy, lactic acidosis, stroke-like episodes, and a de novo A3243G mitochondrial DNA mutation, highlighting the condition's multisystem involvement without ragged red fibers in muscle biopsy.

This study identified novel compound heterozygous mutations in the DSG4 gene in a Japanese patient with congenital hypotrichosis, suggesting overlap between localized autosomal recessive hypotrichosis and monilethrix.

This letter discusses how differentiating features in clinical and radiological findings can help distinguish pulmonary Langerhans cell histiocytosis and Birt-Hogg-Dube syndrome from lymphangioleiomyomatosis, noting overlapping symptoms but specific distinctive traits.

In this case report, a patient with a history of discoid lupus erythematosus experienced an exacerbation of the condition after topical immunotherapy for alopecia areata, suggesting contact dermatitis as a potential trigger.

This review discusses the consensus reached by international experts on guidelines for prescribing and monitoring low-dose oral minoxidil for hair loss, and reports no new clinical results.

This study found that the Hair660™ low-level light therapy device significantly improved hair density and was safe for men with androgenetic alopecia over 24 weeks.

This study found that adding low-level laser therapy to conventional treatment for canine acral lick dermatitis significantly increased hair growth compared to conventional therapy alone, but did not significantly reduce licking behavior.

This study explored the structure and function of lipocalin prostaglandin D synthase, revealing its dual role in substrate catalysis and as a lipophilic ligand carrier, potentially informing future drug delivery design.

This study found that FDA-approved low-level light/laser therapy devices significantly increased hair density in individuals with pattern hair loss compared to sham devices.

This study found that the cytoplasmic dynein component Dynlt3 is essential for effective melanosome transport and transfer in mouse melanocytes, linking melanosome positioning and acidity to the Wnt/β-catenin signaling pathway.

Cathepsin L deficiency causes hair and skin issues in mice.

This study found that cathepsin L deficiency in mice led to significant abnormalities in hair follicle development and cycling, including disrupted hair shaft outgrowth and premature hair growth phase entry.

This study reports that a new DART-HRMS method can effectively analyze intact hair for drug use timelines, with cocaine detection aligning with forensic standards and identifying multiple drugs from high-resolution data.

This study discovered that in *Drosophila*, knockdown of specific storage proteins in adipocytes decreased germline stem cell maintenance, implicating a role for these proteins in adult tissue regulation.

This letter discusses three plasmacytoid dendritic cell-related parameters that may help differentiate lupus alopecia from lichen planopilaris, but it reports no new study results.

This source reports that a comprehensive review of LSS gene variant phenotypes enhances understanding of congenital hypotrichosis 14 and could guide more precise genetic counseling and future research into disease mechanisms and potential therapies.

Mutations in the DSG4 gene cause specific hair and scalp issues.

This study concluded that dermoscopy enhances the diagnostic capability for cicatricial alopecia beyond clinical inspection and identified novel dermoscopic features such as blue-grey dots.

This study analyzed trichoscopic features of discoid lupus erythematosus on the scalp in skin of color and found distinct patterns based on clinical morphology.

This study reported that four patients with lichen planopilaris showed dramatic improvement, including symptom reduction and hair regrowth, after treatment with low-level light therapy.

This quiz article provides a series of dermatological diagnosis questions based on a Journal of Investigative Dermatology article and includes explanations but reports no original research findings.

This review discusses 46,XY disorders of sex development caused by defects in androgen production and highlights the need for long-term care from experienced multidisciplinary teams, but it reports no new clinical findings.

This case report describes a patient with systemic lupus erythematosus who developed Degos disease and non-scarring alopecia, highlighting dermoscopy's role in diagnosis and treatment prognosis.

This description of dystrophy hypotrichosis associated with juvenile macular dystrophy provides an overview of this rare disorder characterized by short hair from birth and progressive loss of central vision but reports no new findings.

This case report presents a rare subtype of hypomyelinating leukodystrophy linked to a PYCR2 gene mutation, emphasizing exome sequencing's value in diagnosing undiagnosed childhood HLDs with atypical symptoms.

In this randomized, double-blind trial, researchers observed that low-level laser therapy led to significantly greater hair regrowth on treated areas compared to a sham treatment in patients with androgenetic alopecia over 24 weeks, suggesting it as a potentially effective and safe option.

This review examines recent advances in bioelectronic nanogenerators for anti-cancer therapy, highlighting various transducing strategies such as photodynamic therapy and electrical stimulation, while also discussing the potential mechanisms for tissue repair and the challenges that lie ahead.

This review discusses the role of the ectodysplasin A2 receptor as a biomarker and driver of ageing related to inflammation, and its potential therapeutic implications, but reports no new clinical findings.
