This review discusses the involvement of vitamin D and its receptor in hair health, focusing on different types of alopecia, but reports no new clinical results; evidence remains inconsistent.

In this case report, a 68-year-old woman with a Leydig cell tumor of the ovary experienced virilization, and surgical removal led to normalization of testosterone levels and regression of symptoms.

This review highlights the role of chronic stress, oxidative stress, and immune processes in the development of Hashimoto’s thyroiditis and polycystic ovary syndrome, emphasizing the potential of antioxidants in their treatment based on the existing literature.

This case report identifies a 32-year-old woman with undiagnosed PHPT-1a who exhibited complete pseudo-anodontia and persistent patchy alopecia areata, suggesting these may be new nonclassical features of a GNAS pathogenic variant.

This study found that a topical treatment combining arginine and zinc significantly reduced hair loss and increased anagen hair percentage in patients with androgenetic alopecia and telogen effluvium, suggesting it might be a promising alternative to finasteride.

This study found that topical application of a cosmetic formulation containing capryloyl glycine 4% significantly reduced hair growth and thickness on the forearms of female participants after 120 days, compared to placebo.

This study found that in stretch-mediated tissue expansion, fibroblasts adopt an embryonic-like, low-collagen state that enhances epidermal stem cell renewal, supporting coordinated skin expansion crucial for reconstructive surgeries.

This study found that the proteins Par3, mInsc, and Gαi3 cooperate to regulate LGN polarization and promote perpendicular cell divisions during murine epidermal morphogenesis.

This review outlines the design and engineering of multifunctional hydrogels, emphasizing their evolving biomedical applications, notably in controlled drug delivery, tissue support, and disease management, and discusses their potential for clinical translation.

This source describes clascoterone, a new topical treatment for acne vulgaris that blocks androgen receptors to reduce sebaceous gland activity and inflammation, offering a lower risk of systemic side effects compared to oral treatments.

This study introduced a pH-responsive polymeric wound dressing that enhances healing in chronic wounds by changing shape and drug delivery based on wound pH, achieving a 94.88% healing rate in diabetic mice by day 14.

This study reported that, in a laboratory setting, araliadiol derived from Centella asiatica activated antioxidant pathways, mitigating urban particulate matter-induced oxidative stress and skin damage.

This review observed that semaglutide may have therapeutic benefits for skin conditions like psoriasis and hidradenitis suppurativa, but reports of adverse skin reactions exist, indicating the need for further research to understand its safety and efficacy in dermatology.

This case study examined a 72-year-old woman with unique hair shaft constrictions consistent with monilethrix, despite features atypical for this condition, ultimately reaching a diagnosis that led to successful improvement using oral minoxidil and reduced hair trauma.

This study developed a simplified multidimensional assessment scale for alopecia areata severity and systemic treatment initiation among Chinese patients, achieving expert consensus on relevant clinical indicators and conditions.

This study examined 16 sporadic trichoblastic tumors and found that although one showed malignant transformation, clinical follow-up revealed no residual or metastatic disease. RNA sequencing indicated a high tumor mutational burden and absence of a UV-related signature, helping to distinguish these tumors from similar growths.

This study found that exosomes from human umbilical cord stem cells, pretreated with lithium chloride, significantly enhance hair regeneration in mice by activating the Wnt signaling pathway through miR-146a-5p.

This study suggests that dual inhibition of P-cadherin and c-Met could be an effective treatment strategy for head and neck squamous cell carcinoma by targeting resistant tumor cells.

This case report highlights the importance of trichoscopy in diagnosing fibrosing alopecia in pattern distribution, distinguishing it from female pattern hair loss, and guiding effective treatment.

This article discusses the diagnostic challenges between certain neonatal scalp conditions and highlights the potential of line-field confocal optical coherence tomography to provide detailed, non-invasive skin examination, without presenting new clinical findings.

This study investigates the potential of umbilical cord mesenchymal stem cells exosome (UCMSC-Exos) to promote hair growth, focusing on its mechanisms of action, though specific results are not reported.

In this case report, a 23-year-old man experienced dizziness, blurred vision, malaise, and fatigue after excessive use of topical minoxidil for three days, with symptoms resolving once minoxidil was discontinued.

This study on male rats found that finasteride treatment led to the differential expression of several genes in the hypothalamus and hippocampus, hinting at potential links to observed side effects like depression, anxiety, and cognitive disturbances.

This study reviews literature indicating that certain drugs used to treat dermatological conditions, such as retinoids and glucocorticoids, may rarely cause psychiatric symptoms like depression and anxiety, which are more commonly observed in patients with skin disorders compared to the general population.

In this study on dogs with yeast imbalances and dermatological signs, a protocol using chlorhexidine and Ophytrium products significantly reduced Malassezia pachydermatis counts and improved pruritus and irritation scores over 21 days, earning positive assessments from veterinarians and owners in most cases.

This study found that fibroblast growth factor 5 may enhance Cashmere goat hair growth by altering the expression of specific genes related to keratin and keratin-associated proteins.

This study found that knocking down lncRNA MTC in Liaoning Cashmere goat skin fibroblasts reduced cell proliferation and altered protein expression, suggesting its role in hair growth and regulatory pathways.

In this study, the P&P Hairline Laser, a hands-free laser-assisted device, was found to produce smoother and more symmetrical hairlines compared to traditional handheld laser devices.
