This article reviews the classification, diagnosis, and management of hair disorders, emphasizing the role of trichoscopy and early diagnosis for effective treatment but reports no new clinical findings.

This review discusses the steroidogenic properties of human skin and suggests that impaired steroidogenesis may be linked to conditions like acne, rosacea, atopic dermatitis, and androgenic alopecia, but reports no new clinical results.

This retrospective review found that while intralesional corticosteroids provided symptomatic improvement for lichen planopilaris, hydroxychloroquine with topical corticosteroids led to higher remission rates but did not result in visible hair regrowth.

This study found that nuclear beta-catenin, LEF1, and PHLDA1 expression was conserved in matrical tumors, suggesting a shared tumorigenesis process involving Wnt pathway activation.

mHa2 and mHa3 keratins have different structures and roles in mouse hair and tongue tissues.

This review discusses recent findings on the mechanisms driving bullous pemphigoid, highlighting epitope spreading and the roles of regulatory T cells, and reports no new experimental results.

This review summarizes the clinical, trichoscopic, and histopathological features of alopecia types associated with cutaneous and systemic lupus erythematosus and explores their links to disease activity, but it reports no new clinical results.

This review highlights the importance of recognizing mucocutaneous lesions in diagnosing juvenile-onset systemic lupus erythematosus, noting that these lesions often improve with controlled lupus and can indicate disease activity.

This study found that substance P may be involved in the pathogenesis of acne by increasing the expression of certain cytokines and receptors in cultured sebocytes.

This review discusses treatment options for tinea capitis in children and reports no new clinical results; the authors recommend newer antifungal agents in cases of griseofulvin treatment failure.

In this study, ketoconazole treatment improved acne in all women and reduced hirsutism in some, but it caused several side effects and requires careful monitoring.

This study found that permanent waving treatment induces structural changes in the cortex proteins of white human hair, significantly reducing its tensile strength without altering the S-S band intensity.

This review examines acneiform eruptions, often drug-induced, highlighting that they differ from acne vulgaris in causes and characteristics, with no new clinical results reported.

This review discusses the use of hair analysis for examining stress and reproduction hormone levels in wildlife and highlights the need for more comprehensive physiological validations across species.

This article reviews the characteristics and classification criteria of cutaneous lupus erythematosus and reports no new clinical findings.

This review discusses how the CRH/POMC systems may regulate human hair follicle pigmentation and highlights the concept of "self-similarity" in melanocortin systems at both local and systemic levels, without presenting new experimental results.

In this study, researchers developed a method to measure steroid hormones in hair and found that body hair typically contains higher levels of cortisone and testosterone compared to scalp hair, but hair pigmentation did not affect hormone concentrations significantly.

This study demonstrates that spatially resolved IR and Raman imaging can effectively reveal the molecular structure and composition of untreated human hair, providing insights into its chemistry and structural integrity.

This review discusses the clinical features of SARS in children, noting milder symptoms compared to adults, and emphasizes the importance of ongoing monitoring for long-term effects; it reports no new treatment findings.

This review suggests that oral prednisolone pulse therapy and oral inosiplex may be effective for alopecia areata, but robust evidence from randomized controlled trials is lacking, highlighting the need for better-designed future studies.

This abstract lists key topics related to non-genomic steroid effects and protein interactions, but reports no new research findings.

This study suggests that chronic stress can lead to decreased skin pigmentation in mice by disrupting the skin's HPA axis, potentially making stress a risk factor for depigmentation.

This review discusses the causes, diagnosis, and treatment of telogen effluvium and reports no new clinical findings; the authors underscore the importance of identifying and eliminating causative factors.

This review discusses the role of the mineralocorticoid receptor in skin biology, highlighting its potential involvement in keratinocyte and hair physiology, and proposes it may affect the side effects of glucocorticoid use.

In this study, the researchers identified the specific subcellular localization of the protein S100A3 in the endocuticle and cortex of human hair shafts.

This study found that the S100A3 gene is exclusively expressed in hair follicle cells differentiating into hair shaft components in mice, suggesting its important role in hair formation.

This review explores the therapeutic potential of bee venom for treating various skin diseases, discussing its mechanisms and effects but reports no new clinical findings.

This article reviews the process of repigmentation in vitiligo and emphasizes the role of UV light as the most potent stimulus, with no new clinical findings reported.

This study reports cutaneous atrophy and alopecia in four patients following greater occipital nerve blockade with triamcinolone and lidocaine, suggesting that alternative steroids may reduce these side effects.

This review provides a practical approach to diagnosing pseudopelade of Brocq and updates on treatment options but reports no new clinical results.
