This review discusses the use of derma rollers for cosmetic purposes and their potential in transdermal drug delivery by summarizing evidence on their design, efficacy, safety, and concerns from preclinical and clinical reports.

This review summarizes recent research on alopecia areata, highlighting advances in targeted therapies due to improved understanding of its immunopathogenesis, though it reports no new clinical results.

In this study, researchers developed and tested a gel containing apocynin-loaded nanoparticles that showed promising results in treating rheumatoid arthritis in rats, suggesting potential for novel topical treatments in inflammatory conditions.

This study reported that using 2D solid-state NMR techniques on extensively labeled mouse fur improves resolution in detecting chemical shifts and secondary structure features, potentially aiding the analysis of the effects of commercial or therapeutic treatments on specific amino acids.

This article highlights that a low suspicion for tinea capitis in adults with scaling and hair loss may delay diagnosis and treatment, urging confirmation through KOH, fungal culture, or biopsy.

This study found that trichoscopy is essential for evaluating the severity of alopecia areata and predicting treatment responses, contributing to more personalized patient management.

This study found that age is the most significant risk factor for hemorrhagic cystitis after hematopoietic stem-cell transplantation, with additional risk factors including cyclophosphamide-based prophylaxis and, among male recipients, prostatic hyperplasia.

This study found that pelage abnormalities in Harlequin mutant mice are linked to severe AIF deficiency and associated with altered expression of genes related to hair structure.

This study estimates that approximately 230,000 tactile afferent fibers innervate the human body's skin, with varying densities across different regions correlating with spatial acuity and hair follicle density.

This study revealed key cellular dynamics and interactions during early embryonic mouse skin development, highlighting complex transitions from precursor states to diverse multilayered structures.

This study suggests that Isaria cicadae Miquel rice fermentation extract may enhance regenerative wound healing of hair follicles in mouse skin through the Hippo pathway mechanism.

This study found that stem cells can temporarily act as non-professional phagocytes during hair cycle regeneration by clearing apoptotic cells through a process requiring local lipids and retinoids for activation, providing insights into their dual role in maintaining tissue integrity.

This study found that sebaceous glands in the skin are primarily renewed by their own stem cells during normal conditions, but after injury, they regenerate through stem cells from hair follicles, highlighting stem cell plasticity and regeneration capabilities.

This study found that SYP123 and VAMP727 are involved in the secretion and transport of inner cell wall components, which is crucial for hardening the root hair shank in Arabidopsis.

This study developed a new method to analyze Cantú syndrome mutations in KATP channels, finding that while Kir6.1 mutations increase sensitivity to potassium channel openers, SUR2B mutations show reduced sensitivity, but both result in marked hyperpolarization compared to wild-type channels under basal conditions.

This study found that ulcerative colitis is associated with diverse molecular changes and chronic inflammation, with some biomarker levels partially recovering during remission.

This study examined wool traits in Angora rabbits using low-coverage whole genome sequencing, identifying six QTLs and a gene, FGF10, linked to fiber growth and diameter, suggesting a cost-effective approach for complex trait analysis in genomic breeding.

This study introduced a new high-throughput method for analyzing scalp hair morphology and found that quantifying hair form provides more accurate information than traditional classification based on racial categories, challenging the belief that cross-sectional morphology predicts hair curvature.

This review concluded that near-infrared and red light photobiomodulation shows potential for certain ocular conditions like age-related macular degeneration and dry eye disease, but clinical evidence is still mixed and insufficient to establish it as a standard therapy.

This study observed that following hair transplantation, patients exhibited prominent perifollicular erythema and scaling one month after surgery, whereas by six months, accentuated follicular ostia and varying hair shaft abnormalities were consistently noted.

In this study, researchers developed a new method called Enriched-GF, which enhances growth factor recovery from platelet concentrates through a combination of glass bead activation, freeze-thaw cycling, and calcium stimulation, outperforming conventional methods by providing higher and more consistent yields for regenerative medicine applications.

This clinical study found that using a cream or lotion as an additional treatment alongside standard care for atopic dermatitis significantly reduced symptoms and improved skin moisturization and barrier function within 28 days compared to standard care alone in participants with mild-to-moderate eczema.

This study investigated the integration of crystal engineering and microneedle technology for androgenetic alopecia treatment, finding that microneedles loaded with newly developed Kopexil multicomponent crystals reduced drug diffusion rates in vitro compared to standard formulations.

This study found that direct co-culture of human bone marrow-derived mesenchymal stromal cells with regulatory T cells enhanced osteogenic gene expression, alkaline phosphatase activity, and matrix mineralization, suggesting Treg's potential in promoting bone regeneration by modulating BMSC mechanobiology through the ROCK-myosin signaling pathway.

The drinkable supplement increased hair growth and was safe for women with hair loss.

This study investigates the complex impact of bariatric surgery on skin disorders, reporting improvements in conditions like acanthosis nigricans and psoriasis, while new issues such as xeroderma and alopecia may also emerge postoperatively.

In this study, researchers identified a gene regulatory network in Arabidopsis that controls root hair growth under low-temperature conditions, revealing specific transcription factors and downstream targets that contribute to this growth response despite overall plant development being halted.

This study found that AP-2α and AP-2β transcription factors are crucial for maintaining adult skin homeostasis, with their inactivation in keratinocytes leading to impaired differentiation, hair abnormalities, and inflammation, highlighting their key regulatory roles.

This study reviews the regenerative potential and clinical applications of exosomes derived from mesenchymal stem cells in conditions like COVID-19, alopecia, skin aging, and osteoarthritis, highlighting their role as a promising tool in regenerative medicine.

This study used a novel fluorescent tagging method in mice to observe collagen IV dynamics during hair follicle development, revealing that alterations in basement membrane turnover can influence epithelial progenitor cell behavior and organ morphology by affecting cell proliferation and movement.
