This study observed that during the rat hair cycle, DNA synthesis in dermal cells peaks during a specific growth stage, suggesting a coordinated metabolic activity with potential implications for alopecia areata research.

This study suggests that increased putrescine levels may disrupt normal hair follicle development in transgenic mice, leading to hair loss and altered skin structure, yet these mice appear more resistant to skin tumorigenesis.

In this study, miR-218-5p was found to enhance hair shaft growth and positively regulate the Wnt signaling pathway by targeting SFRP2 during skin and hair follicle development.

This study used proteomics to identify various proteins in human hair, which may help develop novel biomarkers for hair health, disease, and aging.

In this study, topical application of Thuja orientalis extract promoted hair growth by inducing the anagen phase and increasing hair follicle size and number in telogenic mice.

This study proposes a new method to selectively isolate keratin-associated proteins and keratin from human hair, suggesting that KAPs may support keratin fibers in hair structure.

This review discusses possible medication-induced hair loss and the need to exclude other confounding factors like stress and illness; it reports no new clinical findings and emphasizes careful assessment before attributing hair loss to medications.

This review outlines the steps of contemporary hair transplantation surgery, including the roles of medications and nonsurgical options, but it reports no new clinical findings.

This study concluded that Wnt/β-catenin signaling, through Shh and Bmp pathways, is crucial for determining hair follicle fate in embryonic epidermal development.

This study suggests that hairlessness in nude mice may be due to insufficient expression of phospholipase C-δ1, a molecule essential for normal hair development downstream of the Foxn1 gene.

This study found that hair follicle homeostasis in mice requires vitamin D receptor expression in keratinocytes, independent of its ligand activation.

This speculative review discusses hair cycle-dependent fibroblast dynamics and possible impacts on human hair growth, synthesizing current literature without presenting new clinical findings.

This study found that increasing a drug's lipophilicity and adding ethanol to the donor phase can enhance its delivery to the hair follicle, although the precise transport mechanism remains unclear.

This study found that newborns with neural tube defects and their mothers had significantly lower hair zinc levels compared to controls.

In this study, 95% of respondents reported severe hair breakage or loss after using the Rio Hair Naturalizer System, with many experiencing significant and lasting hair loss.

This study suggests that immunostaining for Keratin 15 may be a useful tool for differentiating between basal cell carcinoma and trichoepithelioma.

This study found that topical application of FK506 stimulated hair growth in animals, which may occur independently of its immunosuppressive effects, though its effect on human hair growth remains unclear.

This abstract does not provide specific findings or results.

This article reviews therapy-related hair disorders in oncology patients, detailing underlying mechanisms and potential management strategies, but reports no new clinical findings.

This study reviews the biology and cosmetic treatment of hair, emphasizing future advancements in safer, more effective procedures to meet consumer needs for hair care.

This study in mice found that overexpressing Sonic Hedgehog in basal cells caused skin anomalies and a lack of certain hair fibers, underscoring its key role in hair follicle development.

This study found that inactivating CerS4 in mice led to hair follicle stem cell exhaustion and hair loss, indicating its role in regulating hair regeneration through ceramide composition and signaling pathways.

In this study, ectopic Wnt10b-mediated β-catenin activation in hair follicles resulted in larger regenerating anagen hair structures, an effect modulated by the Wnt inhibitor DKK1.

This study found that IGF-1 injections increased hair follicle number and growth phase duration in wild-type mice, suggesting potential for baldness treatment.

This study suggests that cultured hair follicle dermal sheath cup cells exhibit immune privilege properties, partly through the expression of PD-L1, which impacts co-cultured immune cells' behavior.

This study found that mice lacking the Vitamin D receptor showed disrupted hair follicle cycling, which was partially restored with hedgehog signaling pathway activation, suggesting a role for this pathway in follicle regulation independent of vitamin D.

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 suggests that chemotherapy-induced anagen effluvium represents patterned hair loss, with most patients retaining hairlines, but patterns do not vary significantly by age, symptoms, or chemotherapy type.

This study found that prolactin plays a direct role in regulating the timing of hair growth cycles in mice by affecting the skin, rather than through other endocrine factors.
