This review discusses the basic principles of hair pathology and findings in common types of alopecia but reports no new research results.

This text resembles an instructional or informational template for journal subscribers and authors, not a research abstract reporting specific findings.

In this study, researchers detailed various surgical techniques for treating vitiligo, including tissue grafting and cell transplantation. They highlighted recent advancements and emphasized the need for future studies to explore therapeutic mechanisms and identify biomarkers to enhance surgical efficacy.

In this case report, the authors describe a rare cystic panfolliculoma in an 84-year-old man's right conchal bowl, noting its potential to mimic other tumors like basal cell carcinoma, which complicates diagnosis.

This study observed that topical application of maslinic acid stimulated hair growth in mice comparably to minoxidil, possibly through the Wnt/β-catenin pathway and involving ciliary gene activity, highlighting increased levels of trichogenic gene expression and protein levels.

This study found that miR-133a-3p and miR-145-5p influenced goat hair follicle stem cell differentiation by inhibiting NANOG expression and promoting SOX9 expression.

This study found that a positive anagen pull test can be an indicator of lichen planopilaris activity, suggesting its utility in the clinical assessment of this condition.

This study found that miR-23b and miR-133 significantly reduce mRNA and protein levels of specific target genes involved in Merino sheep hair follicle development, providing insight into molecular breeding for fine wool production.

This study established the R-7 dermal papilla cell line, which retained essential characteristics of primary cells without undergoing malignant transformation, suggesting its potential for future hair research.

This study found that deleting all three Tet genes in mice led to shorter hair shafts and altered hair types, with associated changes in gene expression and DNA hydroxymethylation.

In this study, mouse sebaceous glands were found to require nerves for growth during active hair cycles, suggesting a nerve-dependent sebaceous gland cycle coordinated with hair growth.

Over 40% of postmenopausal women experience hair loss, with treatments aiming to stop further loss and possibly thicken hair.

Aging causes hair to gray and thin, with the timing of graying varying by race, and factors like oxidative stress and genetics can lead to hair loss.

Mother and son diagnosed with a rare genetic hair loss condition with no effective treatment.

This chapter reviews surgical management techniques for leukotrichia in vitiligo and presents no new clinical findings; it highlights various grafting and epilation methods.

This study found that baicalin activates Wnt/ß-catenin signaling in human dermal papilla cells, increasing alkaline phosphatase expression, growth factor expression, and promoting hair growth in mice.

This paper reviews the effectiveness and side effects of various treatments for androgenetic alopecia, telogen effluvium, and alopecia areata, emphasizing the importance of discussing each option's costs, benefits, and risks with patients.

This study found that rat whisker follicle stem cells can be expanded in culture and transplanted to form functional hair follicles, demonstrating their multipotency and potential for regenerative medicine.

This review discusses hormonal influences on hair growth and suggests that understanding hormone-gene interactions may improve treatment of hirsutism and alopecia, but reports no new clinical findings.

This review discusses advancements in understanding hair cycle and inflammatory alopecias, proposing a standard classification and tiered treatment recommendations, but reports no clinical results.

This study suggests that using trichotillometry to establish the normal range of shear strain for different hair types could inform diagnostic and treatment decisions for various hair conditions.

This case study found that a 7-year-old girl's crystalline cataract had sulfur-containing amino acids likely cystine, and was associated with abnormal hair conditions.

This study observed that both intradermotherapy with 5% minoxidil and topical minoxidil application resulted in perceived improvements in hair density and thickness among patients with androgenetic alopecia, with no significant difference between the two groups.

This article discusses the biologic and psychosocial significance of hair, the current limitations in hair growth drugs, and anticipates future therapies based on advancing hair follicle research.

This study found that VEGF significantly enhances perifollicular vascularization during the hair growth phase, accelerating hair regrowth and increasing follicle and hair size, while its inhibition retards hair growth.

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 study developed molecular signatures for dermal papilla cells and their niche, uncovering novel signaling regulators and genes linked to hair disorders, which may inform future hair development research.

This study found that Shh from neurons signals to Gli1-expressing cells in the hair follicle, cultivating a niche where these bulge cells can potentially transform into epidermal stem cells in wound healing.

This article reviews the stages and regulation of the hair cycle, highlighting molecular regulators involved, but it does not present new research findings.

In this study, researchers found that the number of dermal papilla cells in hair follicles determines hair size and shape in mice, suggesting potential avenues for addressing hair loss.
