This study found that PDLLA filler treatment may help combat age-related hair thinning by reducing oxidative stress and enhancing hair follicle function in both cell and animal models.

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.

This review discusses the biological mechanisms, preparation techniques, and clinical applications of platelet-rich plasma therapy, highlighting its variable outcomes and potential improvements for efficacy and standardization; it reports no new clinical results.

In this study, Rosa rugosa water extract improved hair length and thickness in a mouse model of DHT-induced alopecia by enhancing the expression of hair growth-promoting factors while inhibiting growth-suppressive proteins, suggesting its potential as a natural therapy for hair loss prevention.

In this study, researchers identified eight compounds in Suaeda glauca and reported that its extract may improve hair loss by affecting VEGF, IGF-1 expression, and Wnt/β-catenin signaling, especially compound 4, in human cell models.

This study found that in mice, oral administration of Lactilactobacillus curvatus LB-P9 accelerated hair regrowth and increased hair thickness, hair follicle numbers, and dermal thickness, likely by boosting hair growth factor production and dermal papilla proliferation.

This study reports that taxifolin from enzymatic hydrolysis effectively regulates dermal papilla cell apoptosis and promotes hair growth by increasing IGF-1 and reducing TGF-β1, though it shows less inhibition of DHT compared to minoxidil.

This study uncovered that bimatoprost, a prostaglandin analog, promotes hair growth by activating hair follicle progenitor cells through two pathways: the PTGFR-MAPK signaling axis and an unexpected IGF1R-PCAD-AKT signaling axis, suggesting new potential targets for treating hair disorders.

Secreted inhibitors of Wnt and IGF signaling control hair and tooth development, creating species-specific patterns.

Ursolic and shikimic acid together boost hair growth better than alone.

This study investigated the association between hair loss and medications affecting the GH/IGF-1 pathway, using the FDA Adverse Event Reporting System to analyze reporting odds ratios of alopecia.

In this study, red deer antler extract was found to promote hair growth and increase IGF-I expression in a rat wound healing model.

This study found that collagen peptides from Mozambique tilapia significantly promoted hair regrowth and increased the proliferation of hair growth factors in vitro and in vivo, suggesting potential as supplements for hair loss prevention.

This study found that adenosine promotes hair growth by stimulating the Wnt/β-catenin pathway in cultured human dermal papilla cells through activation of the adenosine receptor.

This study demonstrated that supplementing aged mice with pro-IGF-II improved muscle regeneration by enhancing satellite cell proliferation and reducing adipogenesis, suggesting potential benefits for treating muscle injuries in elderly individuals.

This review discusses the hormonal impact on hair growth and the relationship between endocrine disorders and hair changes, reporting no new clinical results.

This study found that while some extracts from DanGuiBoHyulTangGami-Bang showed potential in inhibiting 5-reductase type Ⅱ and had antioxidant activity, they were not effective in extending the hair growth period.

This review discusses platelet-rich plasma as a treatment for androgenetic alopecia and explains its mechanisms, but presents no new clinical results.

This study found that microemulsions containing ethanol extract of cayenne pepper were effective in enhancing hair growth in rabbits, with the 0.2% concentration achieving the most significant results over a 30-day period, compared to a negative control.

This study found that cortisol increases mac25/IGFBP-rP1 expression in osteoblast-enriched cells from fetal rat calvariae, indicating transcriptional regulation which may influence IGF and insulin effects in bone.

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

This study found that dihydrotestosterone (DHT) suppresses prostaglandin E2 and TGF-β induced IGF-I gene promoter activity in osteoblasts, suggesting complex interactions among bone growth regulators and potential complications from anabolic steroid use.

This study found that in mice, inactivating beta-catenin in the dermal papilla reduces hair follicle progenitor proliferation and disrupts the hair cycle.

Among cultured sebocytes, this study found that bilobetin significantly inhibited lipid production induced by IGF-1, suggesting potential for use in acne treatment.

In this exploratory randomized controlled trial, participants using a combination of Centella asiatica-derived extracellular vesicles with recombinant growth factors showed significant improvements in hair thickness, density, length, and reduced hair loss and scalp sebum content after 56 days, compared to placebo.

This study found that BeauTop, a supplement containing several traditional Chinese herbs, may promote hair growth in mice with alopecia, potentially by modulating EGF and FGF-7 levels.

This study identified genomic regions and genes associated with wool, live weight, body condition, and reproduction traits in Uruguayan Merino sheep, highlighting potential genetic factors influencing these characteristics.
