This study observed that a wearable electric stimulation device significantly promoted hair regeneration in rats and mice, outperforming conventional pharmacological treatments and enhancing growth factor secretion.

Low-dose pulsed electric fields in a rat model shifted hair follicles from resting to active growth, with voltage as the most influential factor.

Processed fat, SVF, and PRP are safe and effective for facial rejuvenation and hair growth.

This study demonstrated that electrical stimulation via a polypyrrole-modified electrode enhanced trichogenic gene expression in human dermal papilla cells, leading to increased hair growth in a mouse model.

This study found that repeated microneedle stimulation in mice promoted hair growth and increased the expression of hair-growth-related genes, suggesting potential therapeutic uses for alopecia.

This study found that testosterone propionate increased hair mass in female hamsters' flank organs, while cyproterone acetate applied topically reduced androgen-stimulated hair in a dose-dependent manner.

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, IL-1α and IL-7 were found to work together to activate epidermal γδ T-cells, which in turn promote hair follicle stem cell proliferation during mouse wound healing.

Thyroid-stimulating hormone affects hair follicles but doesn't change hair growth or color.

This study found that macrophage-stimulating protein (MSP) enhanced hair growth in both human hair follicles cultured in vitro and in mice through the promotion of anagen phase induction.

In this study, researchers found that petroleum ether extract of Eclipta alba significantly stimulated follicular keratinocyte proliferation and reduced TGF-β1 expression in nude mice, suggesting potential use for certain types of alopecia.

This study found that activating TRPV4 in the skin of mice induced hair follicle regeneration by promoting anagen transition, suggesting potential treatment strategies for hair loss.

This study concluded that the inner root sheath inhibits the expression of certain differentiation markers in hair bulbs, with calcium-induced changes paralleling those seen in hair follicle mid-segments.

In this study, researchers demonstrated that human hair follicle outer root sheath cells release ATP, serotonin, and histamine in response to mechanical stimulation, which subsequently activates surrounding sensory neurons.

This study observed that the Pilogics Hairegen device increased total hair count by 23.2% and terminal hair count by 21.1% in 289 patients with androgenetic alopecia after approximately 20 weeks of use, with no adverse effects reported.

In this study, researchers found that both oral and percutaneous applications of melatonin and lyotritone in laboratory rats enhanced hair quality and growth rate compared to a control group, which showed slower hair growth and lower hair quality.

This study on mice found that activating TRPML channels with MLSA1 promoted hair regeneration, accelerated hair cycle transition, and influenced human dermal papilla cells to secrete hair growth promoting factors while reducing hair growth inhibitors and oxidative damage.

In this study, minoxidil nanoparticles significantly increased hair growth rate in C57BL/6 mice compared to traditional minoxidil, suggesting enhanced effectiveness and potential as a new formulation.

This study indicates that higher thyroid-stimulating hormone levels may be linked to post-COVID-19 hair loss in women, while ferritin levels showed no significant correlation.

This study found that mackerel-derived fermented fish oil extract and its component DHA promote hair growth by activating anagen pathways in dermal papilla cells.

In this study, oral Tribulus terrestris extract significantly increased MSH expression in mouse hair follicle melanocytes, suggesting enhanced melanocyte activity and migration.

This article reviews the epidemiology, pathophysiology, and management of androgenetic alopecia, highlighting recent insights into stem cell niches in hair follicles without presenting new experimental findings.

This study found that activating autophagy with specific small molecules and drugs can stimulate hair growth by initiating the anagen phase in dormant hair follicles, suggesting a potential treatment for hair loss.

This review examines the effects of adipose-derived stem cells and their secreted factors on hair growth stimulation in laboratory and animal models, suggesting their potential as therapeutic agents for hair loss treatment.

This study found that the penetration enhancer SEPA™ significantly increased both the speed and amount of hair growth from minoxidil in balding stumptail macaques compared to Rogaine®.

This study found that a herbal hair oil formulation with 7.5% concentration of each active ingredient, prepared using the boiling method, showed excellent hair growth activity comparable to 2% minoxidil.

This study found that Centipeda minima extract promotes hair growth by activating Wnt/β-catenin, ERK, and JNK signaling pathways in human hair follicle dermal papilla cells.

This study found that topical cepharanthine increased IGF-I production in human dermal papilla cells, suggesting it may stimulate hair growth and be a promising treatment option for androgenetic alopecia.

This study found that using conditioned medium from vitamin D3 pre-activated preadipocytes enhanced hair regeneration in mice by promoting angiogenesis.

This study demonstrated that a finasteride-loaded proniosome significantly enhanced transfollicular delivery and hair growth in mice without causing skin irritation, with effects comparable to a 2% minoxidil solution.
