The document explains the genetic causes and characteristics of inherited hair disorders.

This study identified genetic variations in the DSG4 gene among sheep, revealing valuable markers for assessing their impact on wool traits.

This chapter reviews the use of electrospun matrices in creating tissue-engineered skin substitutes and reports no new clinical results; it emphasizes the need for a cell-friendly microenvironment.

Genetic mutations cause various hair diseases, and whole genome sequencing may reveal more about these conditions.

This review concluded that interleukin-17 is involved in the development of female-pattern baldness, suggesting a potential inflammatory role in the condition’s underlying causes.

This study found that two unrelated domestic shorthair cats had novel DSG4 gene mutations causing defective hair shafts, representing the first report of pathogenic DSG4 variants in domestic animals.

This study identified non-structural proteins in preschool children's scalp hair that suggest potential biomarkers for brain development, immune function, and stress response with heritability and age-related differences.

This review discusses natural remedies and nanoparticle formulations for alopecia management and reports no new clinical results, emphasizing potential benefits of herbal treatments over synthetic therapies.

This review discusses the genetic disorder, monilethrix, characterized by fragile, brittle hair and its inheritance patterns, and reports no new clinical results.

In this study, polarized light therapy increased hair regrowth in patients with alopecia areata compared to those who received only minoxidil.

This article discusses the anatomical and biological aspects of hair follicle stem cells in the bulge region but reports no new research findings.

This study found that knock-down of keratin 15 in various cell lines affected cell spreading, morphology, migration, differentiation, and proliferation, suggesting its role in maintaining the stem cell nature of keratinocytes.

This review discusses the use of trichoscopy for diagnosing systemic diseases and concludes that certain trichoscopic features may help dermatologists suspect these conditions.

This study suggests that human hair follicle cells and epidermal keratinocytes differ in their degree of keratinization and other characteristics when cultured on mixed collagen membranes.

Androgenetic alopecia is the only hair loss condition with specific diagnostic criteria in trichoscopy.

This study reports that scalp biopsies in white adults usually have 16.5 hair follicles, primarily in the anagen phase, with male samples showing fewer follicular units but more fibrous tracts in certain areas.

This case report describes how trichoscopy helped diagnose tinea capitis disguised as female pattern hair loss in cases of endothrix infection, highlighting its usefulness in avoiding misdiagnosis.

This study reports a rare case of a 40-year-old woman with multiple calcified trichilemmal cysts, associated with alopecia universalis and suggesting a potential genetic link.

This study found that HLA-B*57 and HLA-Cw*06 were associated with increased risk of psoriasis vulgaris, while KIR2DL2 was more prevalent in controls, suggesting a protective effect.

This study provides evidence for K1 and K10 derivatives' presence in the inner root sheath and hair cuticle, suggesting that these hair follicle parts may follow familiar keratinization principles.

In this study, trichoscopy was diagnostically useful in 97.5% of alopecia cases at a rural Indian hospital, confirming initial diagnoses in most cases and reducing the need for invasive scalp biopsies.

In this study, the authors emphasize the importance of not ignoring the partial presence of comma or harpin hairs and black spots when identifying early lesions of tinea capitis, which may initially be overlooked due to their small size.

This case report describes a 65-year-old man diagnosed with a trichofolliculoma, a benign tumor originating from hair follicles, which appeared as a persistent pore on his cheek.

This review highlights the occurrence of yellow dots, a trichoscopic finding, in several scalp conditions beyond alopecia areata and reports no new clinical results.

This paper highlights trichodynia as a distinguishing symptom of telogen effluvium, but it does not present new clinical findings.

This case report describes a rare pedunculated follicular hamartoma on the nasal septum of a 77-year-old Japanese male, emphasizing its unique clinical and pathological features.

This study found that yellow dots were the most common trichoscopic finding in adult patients with alopecia areata, observed in 88.5% of cases.

This study in Chennai, India, found that while some trichoscopic patterns are specific, many overlap across different scalp dermatoses, highlighting the importance of dermatologists staying informed about the latest findings.

This article discusses the presence of dirty dots as a normal trichoscopic finding in children, noting they are not observed in adults or other age groups, and reports no new results.
