This review discusses the role of oxidative stress in hair greying and suggests that understanding melanocyte susceptibility at different follicular locations may help develop therapies for preventing and reversing the process; it reports no new experimental results.

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 identified hair shaft progenitors in the matrix that regulate hair growth and pigmentation by creating a niche dependent on stem cell factor, implicating KROX20+ cells in these processes.

This study found that sulfur mustard affects hair follicles and sebaceous glands in the skin by causing cellular damage, inflammation, and disrupting wound healing processes in hairless mice.

In this experimental study, there was no impact of the surrounding ferromagnetic film on the magnetization reversal processes in submicrometric antidot arrays, though a significant increase in coercivity was observed.

This article explores the complexity and significance of the hair follicle, emphasizing new insights into its biological roles and the involvement of p53 in follicular regression.

This study analyzed gray hair, revealing that it differs from pigmented hair in follicular activity, oxidative balance, and structure, impacting coloring processes and necessitating adapted techniques to maintain hair quality.

This study reports that extracellular microvesicles isolated from stimulated dermal fibroblasts enhanced hair follicle growth ex vivo and identified norrin as a novel modulator in hair regeneration processes.

This research suggests that testosterone-induced expression of TGF-beta1 and type I procollagen may lead to perifollicular fibrosis in androgenetic alopecia, with finasteride inhibiting this process as a possible mechanism for its effects.

This article proposes a classification for small graft transplants that includes technical factors to improve communication and facilitate comparative studies, reporting no new clinical results.

This article outlines the technical aspects, benefits, and challenges of follicular unit extraction for hair transplantation, but it reports no new clinical findings.

This article discusses the advancements in follicular unit transplantation for hair restoration and reports no clinical results; it emphasizes improved aesthetic outcomes using updated techniques.

This study found that patients with alopecia areata were more likely to experience hearing loss compared to healthy individuals, potentially due to damage to follicular melanocytes involved in the autoimmune process.

This study found that 11% of cutaneous focal mucinosis lesions demonstrated follicular induction, which can mimic basal cell carcinoma histologically and complicate diagnosis.

This study found that hyaluronic acid increased the size of hair follicle germ-like aggregates and the number of proliferative cells but did not maintain specific markers during the process.

This abstract reports no new clinical results and discusses the importance of follicular unit storage for the success of hair transplantation surgery.

This study demonstrated a simple and efficient method to isolate epithelial cells from rat vibrissa follicles, reducing labor and contamination risk while maintaining positive K19 staining.

This study found that recombinant keratinocyte growth factor (rKGF) stimulated hair growth and provided a protective effect against alopecia in murine models, suggesting its role in hair follicle development and regeneration.

This study found that PGF2alpha analogues and PGE2 stimulated hair follicle activity in mice, with PGF2alpha analogues also linked to potential side effects like poliosis when used as eye treatments.

In this study, thymosin beta4 was found to stimulate hair growth in normal rats and mice by affecting key processes in the hair follicle cycle, such as stem cell migration and extracellular matrix remodeling.

This study found that estrogen affected cell behaviors differently in a scratch-wound assay, increasing VEGF secretion in follicular dermal papilla cells but decreasing it in wounded dermal sheath cells.

In this study, electron microscopy of follicular mucinosis showed severe cytoplasmic degeneration in hair follicles, with myelin figures and onion-like lamellar structures, but no indications of mucin release through degeneration or degradation were found.

In this study, transplanted hair follicles from different body sites showed changes in morphology and immune status, suggesting their ability to adapt and function in new recipient areas such as the scalp or eyebrows.

In this study, topical trypsin treatment following depilation in a mouse model induced cell death at the follicular papilla, delaying hair growth and pigmentation.

This study suggests that hair follicles may be the primary target in the onset of various skin diseases, potentially spreading to affect the surrounding epidermis.

This study found that as hair loss severity increased in women with female pattern hair loss, the number of vellus follicles also rose, indicating miniaturization of terminal hair follicles.

This study found that intradermal injection of normal saline before follicular unit extraction significantly reduced wound size and skin mass removed compared to acute extraction, suggesting it minimizes skin injury in this procedure.

This review discusses the methodology, limitations, and advantages of Follicular Unit Extraction in hair transplantation without providing new clinical results.

This study found that acute stress in rats inhibits hair growth, likely through increased cortisol levels and activation of the substance P-mast cell pathway.

This study describes a novel FUE device that may perform successfully across various patient scenarios, adapting to differences in skin firmness, thickness, and hair curliness.
