This study reports that structural abnormalities in the inner root sheath of hair follicles may cause the hair shaft to be loosely attached in patients with loose anagen hair syndrome.

This article discusses the structures surrounding hair follicles and introduces aspects like follicle groups and the dermal sheath, but it reports no new research findings.

This study found that BMP6 and Wnt10b competitively regulate the transition between hair follicle growth phases, offering new insights into hair follicle cycling and potential hair loss treatments.

This study found that estradiol affects hair growth in mice by regulating the transition of hair follicles from rest to growth phases via the estrogen receptor pathway in the dermal papilla.

This study found that platelet-rich plasma significantly improved hair growth parameters in androgenic alopecia patients and was even more effective when combined with minoxidil, particularly in reducing vellus hair.

This study found that active BMP signaling prevents epithelial stem cell activation and expansion in hair follicles, while its inhibition leads to HF stem/progenitor cell overproduction and matricomas.

This study found that injecting PDGF-AA and -BB into mouse skin immediately triggered the hair growth cycle's anagen phase, suggesting potential treatment options for certain types of alopecia.

This study found that epimorphin and a modified peptide, pep7, can stimulate hair follicles to shift from a resting phase to a growing phase in both an organ culture assay and in mice.

Human hair follicles have a unique cell distribution and differentiation pattern during growth.

In this study, the researchers report that a modified epimorphin-derived peptide shows potential for hair follicle regeneration, especially when used with 1% minoxidil in mice.

In this study, oral spermidine supplementation was found to significantly prolong the hair follicle anagen phase and reduce hair loss, with effects persisting three months after treatment in healthy participants, suggesting potential therapeutic benefits for hair loss conditions.

This study suggests that edelweiss extract may promote hair growth and reduce shedding in ex vivo experiments by affecting hair follicle anagen phase duration and keratinocyte proliferation.

In this study, researchers found that bulge cells in mouse hair follicles undergo transient proliferation during early anagen, indicating their role as follicular stem cells. However, another factor beyond dermal papilla proximity may be required to initiate a new anagen phase.

In this study, T3 and T4 were found to directly influence human hair follicles in vitro, enhancing keratinocyte proliferation, prolonging the hair growth phase, and affecting pigmentation.

This study found that prostaglandin receptors are widely expressed in hair follicles, suggesting a complex network of prostanoid pathways involved in hair growth control.

This study provides new insights into the identification and expression patterns of miRNAs in wool follicles, which could improve understanding of wool follicle development in sheep.

This study found that Morus alba root extract activates β-catenin in hair follicle dermal papilla cells, promoting the transition to the anagen phase and enhancing hair growth factor secretion.

This study found that lymphatic vessels promote hair follicle growth in mice and may represent new therapeutic targets for hair loss conditions.

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.

This study revealed gene expression patterns in yak hair follicles during different growth phases, enhancing the understanding of cell fate specialization and providing insights for yak villus development.

This study found that transplanting hair follicles into human scars may remodel fibrotic tissue and reduce scarring by altering collagen structure and decreasing pro-fibrotic factors.

Inhibiting Bmp signaling disrupts hair growth and differentiation.

This study introduced a new classification system for distinguishing between anagen VI and early catagen stages in human hair follicle organ culture, using it to confirm eflornithine's ability to induce premature catagen.

This study found that treatment with mesenchymal stem cell extracellular vesicles enhanced hair growth in mice and stimulated dermal papilla cell activity and growth factor production in vitro.

This study identified key mRNAs and lncRNAs, along with related pathways, that play potentially important roles in hair follicle development and cycling in cashmere goats.

This study found that ephrin-A3 accelerates hair follicle development and increases hair follicle density in neonatal mice, suggesting its involvement in hair growth regulation.

In this study, researchers found that microRNAs and specific target genes, such as MiR-195 and genes like CHP1, SMAD2, FZD6, and SIAH1, play significant roles in regulating hair follicle initiation in cashmere goats.

In this study, researchers found that Dicer, but not Tarbp2, plays a crucial role in regulating the growth phase of hair follicles in post-natal mice.

This study mapped gene expression in different skin structures of dogs, finding similarities to humans that support using dogs as models for human skin diseases.

This study found that basal cell carcinoma cells differentiate along hair follicle lineages and may be influenced by hair follicle cycle modulators for potential therapeutic targeting.
