This study reported that etretinate treatment leads to increased hair shedding due to a sustained decrease in anagen duration, with an arrest at the onset of anagen and a follicular anchorage defect in telogen contributing to alopecia.

This study found that vimentin expression in the hair follicles of Inner Mongolian Cashmere goats is highest during the growth stage and localized to the outer root sheath, suggesting a role in hair cycle regulation.

This study suggests that topical T3 can induce hair follicles to enter the growth phase and may reverse graying in mice, with in vitro results supporting enhanced hair shaft growth.

This article reviews treatment options for male androgenetic alopecia, including minoxidil, 5 alpha reductase inhibitors, and hair transplantation, but reports no new clinical findings.

This study suggests that icariin promotes hair follicle growth in mice by enhancing IGF-1 expression in dermal papilla cells.

This study found that Erica multiflora extract promotes hair growth by enhancing dermal papilla cell activity and shifting hair follicles from the telogen to the anagen phase in both in vitro and in vivo models.

This study found that mu-crystallin gene expression in mouse skin is highest during the anagen phase of hair development, suggesting its possible role in hair follicle growth.

This study found that a stochastic follicular automaton model replicates hair follicle cycle fluctuations, with deterministic simulations aligning with steady-state levels as follicle numbers increase.

In this study, the researchers observed that MMP-2 and MMP-9 significantly fluctuated with the hair growth cycle in mice, suggesting their important role in hair development.

This study found that the protein CCN2 in dermal papilla cells is a physiologically relevant suppressor of hair follicle formation by destabilizing β-catenin, which may help maintain stem cell quiescence.

This study evaluated skin and hair color variations in different mouse strains, highlighting the association between hair cycle stages and skin pigmentation to better understand these features and their implications.

This study found that the water extract of Cinnamomum osmophloeum Kanehira leaves enhanced hair growth in vitro and in a mouse model, suggesting potential use for treating hair loss.

This article discusses the aging-related changes in hair structure and function, and examines various treatments like light therapy, minoxidil, and finasteride aimed at mitigating hair thinning and loss, but reports no new clinical results.

This study found that the fuzzy mutation in mice is linked to both structural hair defects and accelerated hair follicle cycling, influencing the regulation of hair cycle phases such as catagen and anagen.

In this study, mini rats with reduced growth hormone and insulin-like growth factor-1 levels exhibited distinct differences in skin thickness and hair cycle compared to standard Wistar rats, suggesting potential use as an animal model for studying GH deficiency-related skin conditions.

This study found that inducing hair follicles into the anagen-onset stage in mice enhances the immune response to a topically applied DNA vaccine against anthrax.

This study found that the season of the year does not significantly affect the hair regrowth rate or the telogen: anagen ratio in indoor-housed Labrador retrievers.

This study found that BMP2 and BMPR-IA inhibited, while Noggin promoted, hair follicle growth in yaks by affecting skin epithelial cell activity.

This study identified distinct gene expression patterns in wool follicle bulbs that may play important roles in wool follicle cycling and regeneration in sheep.

Eosinophilic infiltrate is not a reliable indicator for diagnosing chronic alopecia areata.

This study found that mice lacking the type 3 IP(3) receptor in their hair follicles experienced repetitive hair loss and regrowth, indicating disrupted hair-cycle regulation potentially linked to specific signaling pathways.

In this study, scalp biopsies from HJMD patients revealed histological similarities to chronic telogen effluvium and highlighted the role of CDH3 mutations disrupting normal hair cycles.

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.

Anticonvulsant drugs may cause temporary chromosomal abnormalities.

This study found that lncRNA-000133 may play a role in secondary hair follicle reconstruction and cashmere fiber growth in goats, potentially through its interaction with the methylation of its regulatory region and dermal papilla cells.

This study reports that BMP2 expression in goat skin is higher during late telogen and early anagen phases, indicating a potential role in hair follicle regeneration.

This study found that the proteins GDNF, NTN, GFRα-1, GFRα-2, and c-Ret are differentially expressed during various stages of the human hair follicle cycle, with potential implications for hair biology.

This article reviews the relationship between hair loss and lithium but does not provide any new clinical findings.

This study found that 6-gingerol, a component of ginger, suppresses hair growth rather than promoting it, both in vitro and in vivo, suggesting potential use in hair removal treatments.

This study found that osteopontin mRNA is abundantly expressed in dermal papilla cells during the catagen phase of hair growth in rats, suggesting a role in this phase.
