This article provides contact information for Bruce A. Morgan and features no new research findings.

This article reviews the classification of hair shaft abnormalities, outlining their diagnostic features, but does not present new research findings.

This review discusses the extraction, purification, modification, and biological activity of polysaccharides from Traditional Chinese Medicine and reports no new research findings.

This review summarizes the current understanding of Wnt signaling in relation to its roles in tissue regeneration and cancer progression and discusses recent medical advancements targeting this pathway for therapeutic purposes.

This review summarizes the major events and regulators of the hair cycle in mammals but reports no new experimental results; it emphasizes the complex regulation of stem cell activation and differentiation during hair growth.

This study found that human hair follicles express ATP-sensitive potassium channels, suggesting that minoxidil acts on these channels and that drugs targeting them may treat hair disorders.

This review discusses the advantages and limitations of various hair loss evaluation methods but reports no new results; it emphasizes the importance of cautious interpretation for these diagnostic tools.

This study introduced a new hair shading model that more accurately simulates light scattering on hair fibers, capturing effects not predicted by previous models.

This chapter reviews the complexity of hair and wool follicle formation, emphasizing the importance of cytological studies to understand the relationship between cellular components.

This review discusses the differences in wound healing between fetal and adult skin, highlighting the potential to uncover genes for scarless repair that could improve adult wound healing.

This study found that topical minoxidil modestly extended the anagen phase in mice by activating β-catenin activity in dermal papilla cells.

This article reviews recent advancements in understanding skin stem cells and their roles in maintaining epidermal homeostasis and repairing wounds, without presenting new experimental findings.

This review discusses the shedding phase of the hair cycle, known as exogen, and reports no new findings while analyzing related processes like club fiber formation and release.

This study found that follistatin and activin interactions are important for hair follicle development and cycling in mice, suggesting that they may regulate processes involving BMP-2 and its antagonist.

This study found that poly(ethylene-co-vinyl alcohol) membranes support the self-assembly of dermal papilla cells into compact spheroidal microtissues capable of inducing new hair follicles, suggesting potential for large-scale production for hair follicle regeneration.

This review discusses the evolution and ongoing debate about the causes of central centrifugal cicatricial alopecia in African American women, without presenting new clinical findings.

This study found that Santolina oil was effective in controlling experimental candidiasis in both in vitro and in vivo settings and enhanced the effectiveness of clotrimazole against Candida albicans in vitro.

This review discusses current and emerging drug therapies for treating androgenetic alopecia and alopecia areata, and reports no clinical results; it highlights a need for improved and novel treatments.

This study found that PHBV cocultured with epithelial and dermal cells might enhance early-stage wound healing by promoting wound closure and re-epithelization more effectively than PHBV/collagen.

Some drugs can cause hair loss, and stopping these drugs often leads to hair regrowth.

This review examines beta-catenin's role in stem cell renewal, lineage selection, and tumor formation in the epidermis and reports no new experimental findings.

This study found that a new topical nitric oxide gel significantly accelerated burn wound healing in mice by enhancing re-epithelialization, hair follicle regeneration, collagen deposition, and angiogenesis compared to controls.

This article reviews major types of genetic hair shaft defects and associated syndromes, emphasizing understanding histologic features and diagnostic methods, but reports no new clinical findings.

In this study, UVB irradiation of organ-cultured human anagen hair follicles in vitro reduced hair elongation and increased cell death, affecting hair growth and regulatory processes.

This study found that Brg1, a chromatin-remodeling enzyme, plays a critical role in hair regeneration and early epidermal repair by regulating bulge stem cells through a Brg1-Shh interaction.

This study found that overexpression of parathyroid hormone-related protein in mice resulted in 30–40% shorter hair due to premature transition into the catagen phase of the hair cycle.

Finasteride increases hair density in female androgenetic alopecia, but individual results may vary.

This study found that only eumenorrheic polycystic ovary syndrome patients showed a temporal coupling between kisspeptin and luteinizing hormone pulsatile secretions.
