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

In this study, researchers developed a non-invasive method to distinguish exogen hair from telogen hair on the human scalp, finding that normal exogen hair levels are generally less than seven hairs per cm².

This study found that NFI-C plays a crucial role in the transition from the telogen to anagen phase of the hair follicle cycle, affecting hair growth initiation in mice.

This review explores the autoimmune hypothesis of alopecia areata and the possible genetic and melanogenesis-associated autoantigens, but reports no new clinical findings.

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 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 suggests that extract from Musa paradisiaca unripe fruit may promote hair growth in mice, indicating potential as a hair growth treatment.

This study found that Sox10 may play a role in early hair follicle development and cycling, as it is expressed in specific regions of the hair follicle during different phases of the hair cycle in mice.

This study found that insect wax can significantly promote hair growth in mice in a way that is comparable to minoxidil, likely due to the upregulation of VEGF expression.

This study suggests that the patchy thickening and reddish discoloration in rabbit skin during the hair cycle may be due to large anagen-phase hair follicles compressing the dermis and increased blood vessels causing redness.

In this study, fermented herbal extracts promoted hair growth and activated Wnt signaling more effectively than nonfermented extracts in mice, suggesting potential benefits for hair regrowth.

This study investigated the role of autophagy in human dermal papilla cells and found that inhibiting autophagy accelerates the catagen phase by reducing Wnt/β-catenin signaling. Furthermore, adding ginsenoside Re appears to restore autophagy, suggesting potential benefits for mitigating hair loss linked to autophagy inhibition.

In this study, norgalanthamine was found to stimulate hair growth in cultured rat dermal papilla cells by activating the ERK 1/2, PI3K/AKT, and Wnt/β-catenin signaling pathways.

This study reports that a 30% ethanol extract of a plant mixture enhanced hair growth in human hair dermal papilla cells and mice, suggesting potential use in hair growth products.

This article discusses alopecia and the impact of hair loss on mental health, but it presents no new research findings and highlights the need for further studies.

This study found that a pet ether extract of Daucus carota promoted hair growth by inducing and prolonging the anagen phase in albino rats, surpassing the effects of 1% minoxidil.

This source describes how androgenic alopecia, or pattern hair loss, affects about 70% of men and is linked to factors like stress, hormonal imbalances, and lifestyle issues, which can also impact psychological well-being and potentially contribute to severe health conditions such as heart disease.

This study used a 3D live imaging system to map cell dynamics in human hair follicles, revealing patterns of cell movement and division that help explain hair fiber extrusion during hair growth.

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

This review discusses telogen effluvium, a common form of hair loss, and reports no new clinical results; the authors outline possible causes, typical prognosis, and management strategies.

This study found that VEGF significantly enhances perifollicular vascularization during the hair growth phase, accelerating hair regrowth and increasing follicle and hair size, while its inhibition retards hair growth.

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 angiogenin is expressed in human dermal papilla cells, where it might stimulate hair growth by promoting cell proliferation and local skin angiogenesis.

This review discusses common hair loss conditions and explores how advancements in hair follicle biology might lead to more effective treatments but reports no new results.

This study found that administering an adenovirus vector to increase Sonic hedgehog gene expression in mouse skin accelerated the transition of hair follicles into the growth phase, promoting hair growth.

This article discusses the hair follicle's regenerative cycles and the molecular mechanisms influencing them, emphasizing the need for therapeutic targeting of the "hair cycle clock" to manage hair growth disorders, without reporting new research findings.

In this study, researchers showed that Wnt ligands secreted by hair follicle epithelium are crucial for hair follicle regeneration and may be significant for treating hair disorders like alopecia.

This study found that the methanol extract of Eclipta alba showed dose-dependent hair growth promoting activity in pigmented C57/BL6 mice by influencing the transition from the telogen to anagen phase.

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.

Hair color production is closely linked to the active growth phase of hair in mice and may also influence hair growth itself.
