In this study, researchers observed that in nude mice, exogenous stimulations lengthened the hair-existing phase and shortened the no-hair phase, with minoxidil influencing male and female mice differently.

In this study, after long-term observation of human scalp hair follicles over 16 years, the researchers found that a topical 5% minoxidil solution could stimulate hair regrowth after a period of dormancy, though with reduced growth rates and hair diameter.

This study used cashmere goats to reveal distinct intermediate states of dermal papilla cells, each with specific roles in hair growth, shedding, and regeneration.

This study found that the GPRC6A-Duox1 signaling pathway influences hair cycle progression and testosterone-mediated hair loss in mice, suggesting that disruption of this pathway leads to resistance against testosterone-induced hair loss and longer anagen phase duration.

In this study, porcine collagen acellular dermal matrix scaffolds combined with mice platelet-rich plasma were associated with increased hair density and follicle regeneration in mice with alopecia, suggesting a potential therapeutic approach.

In this study, researchers observed that telogen hair was more prevalent than anagen hair in both male and female agoutis over a one-year period in Teresina-PI, regardless of dry or rainy seasons, with no significant differences in dermal follicular volume between the sexes.

This study found that TLR2 and its ligand CEP are crucial for maintaining hair follicle health and stimulating hair growth, with deficiencies observed in aging and obesity potentially reducing regeneration.

This study found that miRNAs increase and target mRNAs and lncRNAs decrease from the anagen to telogen phase in mouse hair follicles, and these ceRNA networks may play a role in hair follicle cycling.

In this study, mouse sebaceous glands were found to require nerves for growth during active hair cycles, suggesting a nerve-dependent sebaceous gland cycle coordinated with hair growth.

This review discusses Dr. Gill Westgate's background in hair growth regulation and industry experience, but reports no new findings or results.

This study presents a follicular automaton model that simulates human hair cycle dynamics and can reproduce hair patterns similar to diffuse or androgenetic alopecia by incorporating spatially heterogeneous parameters and follicle miniaturization.

This review discusses differences in hair cycles and epidermal turnover using electronic evaluation, but it reports no new clinical results.

This study observed that PAD type III and trichohyalin are expressed earlier than their deiminated form during the first and second hair cycles in rat hair follicles, indicating a potential additional factor is involved in triggering deimination.

This study observed that mink dermal collagen fibrils undergo structural changes during the hair cycle, with increased fiber thickness and bundle density as minks grow.

This study found that prolactin and its receptor are expressed in the murine hair follicle epithelium, influencing hair cycle phases by down-regulating keratinocyte proliferation during anagen and inducing premature catagen.

This study found that 62% of neutered dogs with hair cycle arrest experienced partial to complete hair re-growth after melatonin treatment, but hair re-growth was not consistently linked to normal sex hormone levels.

TRPV1 helps regulate hair growth cycles.

This study reported that specific non-coding RNAs may regulate the hair follicle cycle in Angora rabbits by acting as competitive endogenous RNAs, enhancing understanding of ncRNA roles in hair growth.

This study observed that Endoglin is crucial for maintaining correct hair follicle cycling and stimulating hair follicle stem cell niches through feedback interactions involving Wnt/β-catenin and Bmp/Smad signaling pathways in a mouse model.

This study investigated protein expression changes during mouse hair follicle cycles and suggested their involvement in biological networks, potentially identifying targets for hair disease therapy.

This study observed that boxer and labrador dogs showed seasonal variations in hair follicle cycles linked to temperature and photoperiod, differing from schnauzers.

Pigs are a good model for studying human hair growth and disorders.

Qu-shi-yu-fa Decoction may help treat hair loss by promoting hair growth and strengthening.

In this study, researchers used yaks as a natural model to investigate hair growth mechanisms, overcoming previous limitations by establishing in vitro models of hair follicle-associated cells and optimizing methods for cell culture and differentiation.

This study suggests that Myelin Protein Zero-like 3 plays a crucial role in hair follicle cycling by regulating anagen and catagen phases, mediated through mitochondrial signaling mechanisms in both human and murine hair follicles.

This study found that Endoglin is crucial for proper hair follicle cycling and the activation of hair follicle stem cell niches, based on its role in the feedback crosstalk between Wnt/β-catenin and Bmp/Smad signals.

This study found that males have significantly longer hair on their thighs compared to females, mainly due to a longer anagen phase and a greater rate of growth.

This study found that feeding mice high levels of dietary vitamin A increased WNT signaling, which activated hair follicle stem cells and may have accelerated alopecia areata progression.

This study found that 6-Gingerol significantly suppressed hair growth in mice by reducing hair follicle number and length, potentially through increased expression of MMP2 and MMP9.

This study analyzed how oxidative hair dye leaches from pigmented and nonpigmented hair during wash cycles, finding that melanin influences the dye deposition and leaching processes.
