This study found that a new hydrogel formulation of basic fibroblast growth factor showed promise in promoting hair regrowth and reducing inflammation in testosterone-treated mice.

In this study, topical minoxidil was reported to increase fenestration in follicular capillary walls around anagen hair bulbs in male rats.

This study found that Substance P increased mitochondrial activity and biogenesis markers in cultured human scalp hair follicles, suggesting a novel link between stress-related neuropeptide signaling and hair follicle mitochondrial responses.

This study found that apple stem cell extract may selectively influence hair follicle bulge stem cell biology without cytotoxic effects in an ex vivo human hair follicle organ culture.

This study found that a dietary supplement containing fermented soy, ornithine, arginine, and Tricovel® Tricoage45+ significantly reduced hair loss and promoted hair growth in menopausal women after 8 to 12 weeks.

The conclusion suggests a new treatment for infantile hemangiomas and a potential target for hair loss treatment.

This study reports that Edelweiss extract significantly prolonged the anagen phase and increased hair density, suggesting potential as an anti-hair loss treatment.

This study reported that the n-butanol fraction of Perilla frutescens extract, particularly rosmarinic acid, showed potential for hair regrowth and anti-androgenic activity in male mice, suggesting it as a possible treatment for androgenetic alopecia.

In this study, women experiencing hair thinning who consumed tailored botanical-based nutraceuticals saw significant increases in linear hair growth rate and other hair health parameters over 90 and 180 days, supporting their effectiveness across different life stages.

This study found that subcutaneous administration of conditioned medium from adipose-derived stem cells promoted hair growth in mice, and hypoxia enhanced this effect by altering growth factor secretion.

This study found that the topical application of a mixture of Platycladus orientalis leaf extract and α-terpineol promoted hair growth in mice by inducing early anagen transition and increasing growth factor expressions.

This study found that photodynamic therapy with methyl 5-aminolevulinic acid was ineffective for treating alopecia totalis, even with microneedle rolling to enhance drug delivery.

In this study, a single dose of PTH–CBD produced a sustained increase in bone mineral density for up to a year in mice, indicating its potential as an osteoporosis treatment.

This study concludes that in men, telogen effluvium (TE) precedes androgenetic alopecia (AGA), with anagen shortening occurring before follicle miniaturization.

This study found that deer antler aqueous extract may promote hair growth in mice by extending the anagen phase and increasing cell proliferation in the hair follicle region.

In this study, different types of catagen in the C57BL/6 mouse model exhibited varying effects on hair follicle melanocytes and melanin distribution, with spontaneous and dexamethasone-induced catagen showing pigment incontinence, while cyclophosphamide-induced catagen retained dendritic melanocytes but increased ectopic melanin.

This study found that when human hair follicles were grafted onto mice, they progressed through dystrophic stages and returned to normal growth, with stem cells aiding in recovery.

This review compiles information on traditional uses, phytoconstituents, and biological activities of Eclipta prostrata but reports no new experimental results; the authors call for more studies to understand its pharmacological mechanisms.

In this study, topical application of Tectona grandis seed extracts on albino mice significantly accelerated hair growth initiation time and increased the percentage of hair follicles in the anagenic phase compared to the standard minoxidil treatment.

This study found that petroleum ether extracts of Citrullus colocynthis reduced hair growth initiation time and advanced more hair follicles to the anagen phase in albino rats compared to untreated controls and minoxidil.

In this study, applying G. glabra root extract to female rats resulted in faster and more extensive hair growth than minoxidil or a control treatment.

This study found that topical application of Citrullus colocynthis extracts reduced hair growth initiation and completion times in albino rats and resulted in similar hair follicle anagen phase activation as minoxidil.

In this study, researchers used transcriptome sequencing and bioinformatics analysis to identify important genes and pathways involved in the transition between hair growth phases, offering new insights into hair follicle cycle regulation and development.

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, 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.

Ashwagandha nanoparticles help hair grow by increasing a growth factor.

The paper concludes that the patchiness of alopecia areata is likely due to when the immune attack happens in the hair growth cycle.

The document explains hair growth, hair loss types, and other hair-related terms.

This article reviews pathologic mechanisms causing hair changes in women on hormonal contraceptives or pregnant and reports no new study results; hormonal effects on the hair cycle stages are suggested.

This article discusses the impact of estrogens on hair follicle growth in female pattern hair loss, noting their ability to increase anagen phase and suppress telogen phase, but reports no new clinical results.
