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 a combination of insulin-like growth factor-1 and epidermal growth factor significantly promoted hair follicle growth and development in both cultured hair follicles and rabbits.

This study suggests that sinapic acid may promote hair growth in human hair follicle dermal papilla cells by activating specific signaling pathways and inducing the expression of growth factors.

This study found that Chamaecyparis obtusa oil increased hair follicle cell proliferation and maintained the anagen phase in mice, suggesting a potential for promoting hair growth.

This article reviews the types and characteristics of adrenal cortex tumors, including their hormone secretion and detection as incidental findings, but presents no new research results.

This review discusses the high prevalence of androgen excess and PCOS in women with type 1 diabetes but reports no new clinical findings; the authors highlight the underdiagnosis of hyperandrogenism in these patients.

This review discusses hormonal influences on hair growth and suggests that understanding hormone-gene interactions may improve treatment of hirsutism and alopecia, but reports no new clinical findings.

This study demonstrated that FGF5s acts as an inhibitor of FGF5 in regulating hair growth cycles in cashmere goat dermal papilla cells.

This review discusses the potential benefits of flavonoid-containing botanicals, such as Panax ginseng, in reducing hair loss and promoting hair growth, but reports no new experimental results.

This study reports that stimulating sensory neurons with capsaicin and isoflavone increases IGF-I production, promoting hair growth in mice and human volunteers with alopecia.

This study found that adiponectin promotes hair growth in cultured human hair follicles, suggesting its receptors could be a target for clinical hair growth strategies.

This review discusses psychological impacts associated with facial acne, noting that high levels of anxiety and depression among these patients are not linked to oxidative stress, and reports no new clinical results.

This study suggests that Platycarya strobilacea extract promotes hair growth in mice by enhancing stem cell factor expression, reducing mast cell numbers, and increasing cytokines associated with hair growth.

In this study, the herbal hair tonic and natural food treatment in C57BL/6 mice were associated with increased hair density and thickness compared to controls, suggesting potential hair growth benefits.

In this study, the researchers found that the water-soluble fraction of Rhus semialata gall extract and its component Penta-O-Galloyl-β-D-Glucose promoted hair growth in human dermal papilla cells, and clinical trials supported these findings, showing improved hair density and appearance compared to placebo.

This study suggests that oleanolic acid may promote hair growth in mice with testosterone-induced androgenetic alopecia by activating the Wnt/β-catenin pathway and influencing various molecular levels.

Oral processed egg yolk improves hair regrowth and quality in alopecia patients.

This study found that ultraviolet radiation causes significant damage to human hair follicles, including increased cell apoptosis and oxidative DNA damage, but this damage may be mitigated by topical caffeine.

This article reviews the role of hormones in human penis development and associated conditions due to hormonal imbalances, but reports no new findings, suggesting hormone replacement can manage some conditions.

Hair papilla cells are crucial for blood vessel development in hair follicles, affecting hair growth and loss.

This study found that women with female pattern hair loss had significantly lower serum IGF-1 levels than controls, suggesting a possible role for IGF-1 in this condition.

This study found that women with female pattern hair loss had significantly lower serum IGF-1 levels compared to controls, but no significant association between IGFBP-3 levels and hair loss severity was observed.

This study found that STAT3 signaling is essential for initiating the hair growth phase but not involved in hair follicle development during the fetal period.

This study found that 1,550-nm Er:Glass fractional laser treatment increased hair density and shaft diameter in patients with androgenetic alopecia, but did not up-regulate Wnt10A and IGF-1 mRNA expression.

This study found that patients with acne vulgaris had higher serum IGF-1 levels and more intense FoxO1 and mTOR expression than controls, suggesting their role in acne pathogenesis.

In this study, IGF-I was shown to enhance human hair follicle growth, maintain the anagen phase, and increase expression of certain growth factors and anti-apoptotic markers.

This study found that intramuscular injections of a PRP-derivative in healthy beagle dogs did not result in statistically significant changes in lumbar muscle tissue or IGF-1 blood concentration, suggesting the treatment may be safe at therapeutic doses.

This study demonstrated that topical oleuropein induced hair growth in mice by activating the Wnt10b/β-catenin signaling pathway and increasing expression of several growth-related genes in skin tissue.

This study found that selenium deficiency in mice accelerated age-related conditions and metabolic decline but unexpectedly promoted longevity, suggesting low selenium levels might separate healthspan and lifespan.

In this study, pioglitazone treatment in insulin-resistant PCOS patients decreased relative 5alpha-reductase activity without significantly affecting cortisol levels or urinary cortisol excretion.
