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.

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

This study found that thrombospondin-1 plays a critical role in hair follicle cycle regulation, with deficiency prolonging follicle growth and overexpression delaying it through antiangiogenic effects.

This study suggests that the COX-2 enzyme plays a role in hair follicle biology, as transgenic overexpression in mice induced hair follicle cycling disturbances and alopecia, which was mitigated by COX-2 inhibition.

This study found that STAT5 activation in the dermal papilla acts as a key switch to trigger anagen entry in postdevelopmental hair follicle cycling.

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 a spermidine-based nutritional supplement increased the number of anagen phase hair follicles in healthy humans, suggesting potential benefits for hair loss conditions.

In this study, γ-ray irradiation of mice reduced hair follicle density and pigmentation, suggesting damage to stem cells and progenitors for keratinocytes and melanocytes.

This study found that CARI ONE, a herbal mixture, promotes hair growth in mice by inducing the transition from telogen to anagen phase and enhancing hair follicle development, compared to control and minoxidil treatments.

In this study, researchers analyzed dermal papilla cells from cashmere goats and identified 3,857 differentially expressed genes associated with hair growth phases, follicle types, and sex, providing a foundational resource for future efforts to improve cashmere quality and yield.

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.

In this study, γ-ray exposure in mice decreased hair follicle density and pigmentation, suggesting damage to stem cells affecting hair follicle regeneration.

In this study, γ-ray irradiation in mice during the first telogen phase led to decreased hair follicle density and pigmentation anomalies, suggesting damage to stem cells and progenitors for keratinocytes and melanocytes.

This study found that biglycan, a protein secreted by dermal papilla cells, plays a critical role in hair follicle cycle regulation and regeneration in mice by activating the Wnt/β-catenin signalling pathway, suggesting its potential as a treatment target for hair loss.

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 research reported that STAT5 activation in the dermal papilla plays a crucial role in triggering anagen entry during post-developmental hair follicle cycling.

The study demonstrated that both DKK2 and SOSTDC1 are necessary for normal timing of the first catagen phase in mice hair growth cycles.

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, the misshaped and hairy ear phenotype in mutant mice was linked to mis-expression of certain Hoxc genes due to a chromosomal inversion.

This study reports that Plantago asiatica L. extract may promote hair growth by enhancing growth factor production and activating specific signaling pathways in hair follicle dermal papilla cells.

In this study, the elimination of NG2+ hair follicle stem cells during the anagen phase was associated with an aggravated sensitization phase of allergic contact dermatitis, suggesting their immunosuppressive role.

This study found that the BMP antagonist noggin induces hair growth in postnatal skin by neutralizing BMP4's inhibitory activity, potentially mediated by changes in Shh expression.

This study demonstrates that pea sprout extract promotes hair growth by activating specific signaling pathways and providing antioxidant and anti-inflammatory effects, suggesting its potential as a natural alopecia treatment.

In this study, adenosine was found to stimulate hair follicle growth in vitro by promoting growth factor expression, β-catenin activation, and downstream signaling pathways.

3D ultrasound can detect hair follicle changes and disease phases in alopecia areata.

TP0427736 may help treat hair loss by blocking a specific protein and promoting hair growth.

This study utilized 3D ultra-high frequency ultrasound to effectively detect different disease phases of alopecia areata by visualizing hair follicle structures and identifying unique pathological signs, offering a promising non-invasive diagnostic tool that surpasses conventional methods.

This study found that transgenic mice expressing HPV E6/E7 in the outer root sheath experience continuous hair follicle cycling due to delayed catagen entrance and insensitivity to telogen resting signals.

This study suggests that policosanol may prevent androgenetic alopecia in mice by regulating hormone levels and suppressing premature hair follicle entry into the regression phase.

RCS-01 is safe and may help rejuvenate aging skin.
