This study introduced a simple and reliable in vitro assay capable of large-scale simultaneous screening of hair growth-promoting compounds using a 3D co-culture system of human dermal papilla and outer root sheath cells.

This study found that blood and milk somatic cells show promise as matrices for monitoring illicit recombinant bovine somatotropin use in dairy cattle through gene-expression assays.

The researchers concluded that baicalin may promote hair growth and follicle proliferation by activating the AKT pathway, suggesting its potential as a treatment for alopecia.

This study observed that age influences fur quality and hair follicle traits in Rex rabbits, with significant differences in the Wnt10b/β-catenin signaling pathways during hair follicle development, suggesting the ideal slaughter age should not be earlier than 120 days to maximize fur characteristics.

This study suggests that type I 5-alpha reductase may also play a role in hair growth, with dutasteride potentially being more potent than finasteride in modulating key hair growth gene expressions.

This study found that Katsuwonus pelamis heart hydrolysates promoted hair growth in human dermal papilla cells, a 3D hair follicle organoid model, and C57BL/6 mice, suggesting its potential as a bioactive hair growth ingredient.

ABS-201 may effectively promote hair growth in men by targeting the prolactin receptor.

This study found that Limosilactobacillus reuteri NCHBL-005, derived from honeybees, may promote hair growth via a novel non-androgenic mechanism involving the Wnt/β-catenin signaling pathway, as it increased hair follicle size and number in mice and influenced related gene expression in human follicle cells.

This research found that kaempferol, a flavonoid from hair growth-promoting plants, significantly enhanced human dermal papilla cell proliferation and inhibited specific signaling pathways, outperforming minoxidil, with topical application in mice promoting hair growth and thickness, indicating potential as a natural hair loss treatment.

This study developed microneedles combining insulin-like growth factor-1 and type XVII collagen, showing more effective hair regeneration and reduced inflammation compared to minoxidil in a mouse model of androgenetic alopecia.

This review discusses the mechanisms regulating wound-induced hair-follicle neogenesis and highlights potential treatments, like Wnt signaling activators, for enhancing this process in humans, yet reports no new clinical results.

Veratric Acid may help promote hair growth and reduce hair loss.

In this study, researchers analyzed skin tissue from two sheep breeds during the growing period and identified 56 differentially expressed lncRNAs and 616 mRNAs linked to hair follicle development, suggesting potential targets for improving sheep wool quality through genetic and molecular approaches.

This study investigated m6A RNA modification in hair follicle development, finding that Hycole rabbits displayed longer hair, higher primary hair follicle ratios, and thicker skin compared to Rex rabbits, while also identifying key differential genes and pathways involved in hair growth.

In this study, researchers developed WS Biotin, a new water-soluble form of biotin, and found that it significantly improves water solubility compared to free biotin and enhances hair-related keratin expression, gene activity for hair growth in vitro, while also reducing melanin content in skin cells.

In this study, the alcoholic extract DN106212 from Centipeda minima was shown to be more effective in promoting hair growth in C57BL/6 mice compared to dimethyl sulfoxide and tofacitinib, suggesting its potential as a natural hair growth agent.

This study found that recombinant type III collagen may aid skin aging management by promoting fibroblast proliferation and migration, with a modest impact on inflammatory marker IL-6, though it did not significantly affect TNF-a secretion in vitro.

This study suggests that infiltrating M2 macrophages promote wound-induced hair neogenesis in mice by producing growth factors that activate the wnt signaling pathway during the late phase of wound healing.

This review discusses Dr. Gill Westgate's background in hair growth regulation and industry experience, but reports no new findings or results.

This study found that the water extract of Cacumen Platycladi promotes hair growth and follicle development in mice, possibly by influencing dermal papilla cells through the Akt/GSK3β/β-Catenin signaling pathway.

This study found that the expression of IGF-1 receptor was significantly reduced in women with female androgenetic alopecia compared to healthy controls.

This review discusses the complex relationship between anabolic substances and colorectal cancer risk, reporting ambiguous findings on their carcinogenic properties, potential synergy with risk factors, and protective roles.

This study reviewed Woodhouse-Sakati syndrome and found it consistently associated with hypogonadism, decreased IGF1, and frontotemporal alopecia, with additional symptoms like intellectual disabilities and diabetes in some patients.

Increased IGF-1R expression is linked to thicker skin growth.

In this study, miliacin combined with polar lipids significantly stimulated IGF1 production, increased the renewal of keratinocytes, and enhanced collagen thickness in a hair follicle model.

This study found that adding methionine to a low-protein diet improved wool production and feed efficiency in Angora rabbits by promoting hair follicle development through mechanisms involving IGF1, KAP, and versican signaling.

This study observed that PCR-based genotyping for cre-loxP mice can lead to errors due to cre-mediated recombination in non-target tissues like tails, affecting the detection of lox alleles.

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.

In this animal study, researchers found that daily oral intake of salmon nasal cartilage proteoglycan enhanced hair growth in mice, potentially through a signaling pathway that stimulates specific growth factors in human follicle cells.

This review discusses the potential carcinogenic effects of anabolic androgenic steroids, particularly regarding Leydig cell tumors, and highlights the need for preventive information campaigns due to associated health risks.
