This review summarizes the volatile components, biological activities, and potential safety concerns of essential oils from various Curcuma species, but reports no new clinical results.

In this study, platelet-rich plasma significantly increased hair regrowth and reduced symptoms of alopecia areata compared to triamcinolone acetonide or placebo, with no observed side effects.

This review discusses advances in understanding mammalian stem cell niches, particularly in bone marrow, tooth, and hair follicle, and highlights the potential for developing therapies targeting these niches for tissue repair.

This study describes a system for generating hair follicles from dissociated cells in mice, suggesting that successful development requires a foundational epithelial platform.

This study concluded that current cross-sex hormone treatments for trans men and trans women are effective with a low risk of side effects in the short term, though they did observe specific clinical changes.

This review discusses completed and ongoing clinical studies on microneedle-based technologies for cosmetic, therapeutic, and diagnostic applications and reports no new clinical results.

This article reviews the structure and chemistry of hair across ethnicities and how these factors affect hair properties and treatment responses, but reports no new research findings.

This study found that female COVID-19 survivors were more likely than males to experience multiple long-term post-COVID symptoms, including fatigue, pain, hair loss, and mood disorders.

This study found that transgenic expression of COX-2 in mouse basal keratinocytes causes epidermal hyperplasia and certain dysplastic features at specific body sites.

This review discusses the multifaceted actions of metformin in polycystic ovary syndrome and reports no new clinical results; the authors emphasize metformin's potential benefits in both cardiometabolic and reproductive aspects of PCOS.

This study found that while a tip-focused calcium gradient influences localized growth in root hairs and pollen tubes, it is not the primary determinant of growth direction in root hairs of Arabidopsis thaliana.

In this study, researchers found a significant positive association between cortisol levels in hair and feces of domestic cats and dogs, suggesting hair cortisol assays could be a viable option for monitoring chronic stress.

This study found that lifestyle interventions improved body composition, hyperandrogenism, and insulin resistance in women with PCOS, but did not affect glucose tolerance, lipid profiles, or clinical reproductive outcomes.

This review discusses human sebocyte in vitro models for studying sebaceous gland function and control but reports no new clinical results, highlighting hormonal effects and the impact of retinoids on sebocyte activity.

Radiofrequency devices effectively tighten skin without surgery.

This study found that previously undescribed WNT10A mutations are a prominent cause of various forms of ectodermal dysplasia, including OODD and Schöpf-Schulz-Passarge syndrome, with gender-specific phenotypic effects noted.

This study found that dermoscopic indicators like black dots and tapering hairs are valuable markers for diagnosing and assessing the severity and activity of alopecia areata in Asian patients.

This review discusses the bioactive phytochemical and biological activities of Psoralea corylifolia, emphasizing its potential therapeutic uses, and reports no new clinical results; the authors call for further clinical trials.

This review discusses the interplay of hyperandrogenism, insulin resistance, obesity, and their role in polycystic ovary syndrome, but presents no new clinical results.

Genetic variation in the androgen receptor gene mainly causes early-onset hair loss, with maternal inheritance playing a key role.

This study found that psychoemotional stress disrupts hair growth in mice by terminating anagen and suggests a potential pathway for pharmacological management of stress-related hair loss in humans.

This study demonstrated that blocking the Sonic hedgehog signaling pathway in mice led to reversible inhibition of body coat hair morphogenesis, while whisker development was unaffected.

This review examines hair cosmetics, including shampoos and conditioners, for their formulations and effects, but reports no new clinical findings; it emphasizes the importance of dermatologist knowledge in treating diverse hair conditions.

The researchers reported that hair follicle development and commensal microbe colonization promote the accumulation of regulatory T cells in neonatal skin, with the Ccl20-Ccr6 pathway playing a key role in this process.

This review discusses skin-related toxicities associated with targeted cancer therapies and emphasizes the need for dermatologists to understand and manage these adverse effects, but reports no new experimental results.

This article examines the terminal to vellus transition in androgenetic alopecia through cellular and developmental mechanisms, discussing challenges and knowledge gaps without presenting new clinical findings.

This study found that polycomb-group-mediated repression plays a key role in regulating hair follicle stem cell states and lineage progression by distinct mechanisms in adult mouse skin.

This study found that surgical deactivation of migraine trigger sites significantly reduced or eliminated migraine symptoms in most treated patients, compared to controls, and also decreased migraine-associated costs and workdays lost.

This review discusses the potential uses, benefits, and challenges of solid lipid nanoparticles in drug delivery systems but presents no new experimental findings.
