This review discusses recent advances in hair follicle research, highlighting therapeutic and cosmetic applications, but reports no new study results.

In this study, the expression of certain hair follicle-related genes differed between growth phases in Angora goats, with HOXC13 showing overexpression during the anagen phase, potentially influencing the mohair's shine and texture.

This study observed that pilose antler extract promoted hair growth in mice with androgenetic alopecia by stimulating the hair follicle growth cycle via the SHH/GLI pathway activation and BMP/Smad pathway suppression.

This study found that HOXC13 gene expression was significantly higher during the anagen phase in Angora goats, potentially contributing to the mohair's shiny and silky nature.

In this study, the researchers observed that male pattern alopecia is characterized by miniature follicles, enlarged sebaceous glands, and an increased number of mast cells, without significant abnormalities in enzyme activity.

This study found that the absence of the vitamin D receptor disrupts hair follicle structure during the first catagen in mice, linked to increased expression of the hairless gene.

This review discusses the influence of oestrogens on various skin components and highlights their modulatory roles and receptor pathways, but it reports no new clinical results.

This study observed various patterns of permanent alopecia in breast cancer patients treated with taxanes and adjuvant hormonal chemotherapy, hypothesizing disruptions in hair follicle cycles due to chemoinflammatory and hormonal factors.

This study found that applying TPA to mice accelerated hair follicle regeneration by activating Akt and Wnt/ß-catenin signaling pathways, involving hair follicle stem cell proliferation.

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 human hair follicles with a completely destroyed bulb can regenerate after being grafted onto immunodeficient mice, entering a shortened dystrophic telogen followed by anagen phase.

This study found that anagen hairs require less force to be extracted than telogen hairs in an in vitro pig skin model, indicating different anchorage mechanisms.

This study found that concentrated nanofat, used alone or with decellularized nanofat, may enhance hair growth in mice by activating dermal papilla cells and the anagen phase.

This chapter reviews signaling pathways related to androgenic alopecia in dermal papilla cells of balding human scalps, integrating published information and analysis of molecular interactions, without reporting new clinical results.

This study found that keratin 17 and TNFα play interdependent roles in regulating hair follicle cycling, with TNFα required for the anagen–catagen transition and its ablation partially rescuing hair cycling defects in K17-null mice.

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 study demonstrated that bioengineered hair follicles reconstituted from embryonic skin cells and transplanted into hosts can restore physiological hair functions, suggesting potential applications for treating alopecia.

This review discusses the need for more research on how the chronobiological control systems regulate hair follicle cycling and reports no new results.

In this study, researchers developed a non-invasive method to distinguish exogen hair from telogen hair on the human scalp, finding that normal exogen hair levels are generally less than seven hairs per cm².

This review discusses recent advances in understanding the Eda pathway's role in developmental biology, and highlights ongoing trials and areas for further research, including Eda's potential involvement in cell processes and disease.

This review discusses methods for evaluating hair growth-promoting effects of candidate substances for androgenetic alopecia, focusing on cell assays, organ cultures, and animal models, and reports no new results.

In this mouse study, NF-κB was shown to play a role in hair follicle cycling and morphogenesis, with specific activity patterns differing by hair type and involving noncanonical signaling for zigzag hair bending.

This study found that during dialysis, lower plasma-potassium levels were associated with hyperglycemia, suggesting potassium correction is vital when using glucose-rich dialysate.

This study found that numerous genes involved in hair growth, including 73 co-up-regulated ones, were differentially expressed in goat hair follicles during the hair growth cycle.

In this study, growing human hair follicles in a defined glycosaminoglycan hydrogel ex vivo promoted cell survival, proliferation, and activation of hair growth-related signaling pathways, suggesting GAG-based hydrogels could modulate the hair follicle growth cycle.

This chapter discusses the structure and function of the skin, detailing its protective roles and the layers that comprise it, but reports no new research findings.

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.

The document explains how hair is studied in forensics to identify its source and its role in criminal investigations.

This chapter discusses stem cell activity in feather and hair follicles, emphasizing how stem cells maintain their population by cycling between quiescence and activation in specialized niches but reports no new results.

This review article examines recent studies on the role of diverse immune cells in forming an active niche for hair follicles, offering new insights into hair growth and related diseases.
