This study found that trichoscopy, a non-invasive diagnostic method, may effectively differentiate between types of focal alopecia in the parietal area in adult women, indicating specific trichoscopic features for conditions like alopecia areata, discoid lupus erythematosus, and lichen planopilaris.

This study identified that trichoscopy can effectively diagnose frontal fibrosing alopecia by highlighting specific scalp abnormalities in postmenopausal women.

This case report describes a trichofolliculoma with perineural invasion, highlighting a rare and clinically significant finding in a typically benign hair follicle tumor.

This study demonstrates that mouse eyelashes can effectively model human eyelash growth to analyze morphology, development, and the effects of growth-stimulatory agents like bimatoprost.

This study observed that the glassy layer of hair follicles in guinea pigs consists of thick collagen-type fibrils organized into two distinct arrays, whereas in young mice, the fibrils are thinner and develop between the outer root sheath and fibroblasts.

This report describes a rare case of Trichostasis Spinulosa on the heel, an uncommon location for this type of lesion.

This study developed a prototype device that suggests potential for diagnosing changes in hair quantity, diameter, and density, though formal clinical studies are needed to confirm these findings.

Hair papilla cells are crucial for blood vessel development in hair follicles, affecting hair growth and loss.

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 concluded that trichoscopy is an effective, non-invasive tool for diagnosing telogen effluvium, with significant differences in trichoscopic findings between frontal and occipital scalp regions, aiding in distinguishing it from androgenetic alopecia for early diagnosis.

Merkel cells are abundant in facial vellus hair follicles, especially during the anagen phase.

This article reviews the Directory of Open Access Journals, an extensive global index of quality open access journals, and reports no new results.

This review introduces the morphological and molecular principles of hair follicle development but reports no new experimental results, focusing on recent insights and forming a working hypothesis.

This article discusses the hair follicle's regenerative cycles and the molecular mechanisms influencing them, emphasizing the need for therapeutic targeting of the "hair cycle clock" to manage hair growth disorders, without reporting new research findings.

This review discusses the role of androgens in hair follicle regulation and suggests that a better understanding could enhance treatments for conditions like hirsutism and alopecia, but does not present new findings.

A gene called APCDD1, which controls hair growth, is found to be faulty in a type of hair loss called hereditary hypotrichosis simplex.

This review discusses the potential mechanisms and evidence supporting low-level laser therapy for stimulating hair growth in men and women, while noting its safety and effectiveness but needing further study on specific parameters.

This review discusses the various stem cell populations associated with hair follicles and their potential in regenerative medicine, highlighting differences between murine and human hair follicles but reports no new clinical results.

This study found that the HairMax LaserComb® significantly increased hair density and was safe and well tolerated for treating androgenetic alopecia in men compared to a sham device.

This review provides a comprehensive guide to serum-free human hair follicle organ culture methods, highlighting research opportunities, standardization efforts, and potential applications without reporting new empirical findings.

This review discusses the hair follicle cycle's complex regulation and highlights the potential for targeting catagen control in future therapies without presenting new experimental data.

This review discusses the molecular mechanisms of androgens and androgen receptors in skin disorders, particularly androgenetic alopecia, and reports no new clinical results; it highlights potential areas for future treatment development.

This review explores the hormonal regulation of hair growth and changes with season, age, and sexual development, and calls for improved treatments for hair disorders.

This review discusses the genetic factors involved in hair follicle morphogenesis and cycling and reports no new clinical results; it emphasizes the role of genes in hereditary hair diseases.

This study found that beard hair medulla cells express an unexpected range of keratins, showing variability and promiscuous behavior in keratin interactions distinct from other hair follicle cells.

This review explores the role of Foxn1 in mammalian skin biology, discussing its influence on hair follicle function and the potential for further research to enhance understanding of epithelial differentiation.

This study found that using a low-level laser comb led to hair regrowth in a mouse model of alopecia areata, while sham-treated mice showed no hair regrowth.

This review discusses how macro-environmental factors such as intradermal adipose tissue and sex hormones influence hair and feather stem cell niches, suggesting environmental targets for regenerative medicine, but reports no new clinical results.

This study found that prolactin is a key regulator of keratin expression in human hair follicles, enhancing specific keratin types and influencing epithelial stem cell-associated keratins.
