In this animal study, rosehip seed oil applied to the skin of mice promoted hair regrowth by accelerating hair follicles' transition from resting to growth phases and increased hair follicle density, bulb size, and skin thickness, suggesting potential as a treatment for hair loss.

This analysis concluded that the evidence does not establish a cause-and-effect relationship between iron intake and the maintenance of normal hair growth in non-menopausal women with excessive hair loss.

This study found that soil phosphorus availability was the key factor in phosphorus uptake by maize, while tillage affected root distribution and extractable phosphorus within top soil layers.

This laboratory study found that nonanal, a plant scent compound, may stimulate growth factors and cell proliferation in human hair follicle dermal papilla cells, suggesting a cAMP-mediated mechanism.

This review found that deficiencies or imbalances in micronutrients like vitamin B, vitamin D, iron, and zinc may play a role in androgenetic alopecia and could be modifiable risk factors for prevention and treatment, though evidence varies.

This article reviews the impact of nutritional deficiencies on hair health, detailing how they can cause structural abnormalities, pigmentation changes, or hair loss; it presents no new clinical findings.

This study found that a 6-month supplementation with omega 3, omega 6, and antioxidants significantly improved hair density and reduced hair loss in women with female pattern hair loss.

This review discusses the impact of various external factors like cosmetics, traction, and radiation on hair health and color, but reports no new findings.

This study found that, in female patients with idiopathic telogen effluvium, a supplement containing zinc, biotin, and other nutrients significantly improved hair loss and quality over 180 days, whereas another supplement with different ingredients had less consistent effects.

Nutrition is important for skin health, and changing diet can help prevent and treat skin diseases.

This article discusses hypothyroidism, its symptoms, causes, and the importance of lifestyle modifications in supporting thyroid health, but it reports no new clinical results.

This study systematically reviewed meta-analyses and Mendelian randomization studies to identify factors influencing prostate cancer risk, finding suggestive associations for physical activity, height, and smoking but no robust, convincing overlapping evidence across tested factors.

This review discusses the role of dietary habits and lifestyle modifications in managing polycystic ovary syndrome and reports no clinical results; the authors emphasize the need for tailored diet therapy in affected women.

In this study, adenosine was found to stimulate hair follicle growth in vitro by promoting growth factor expression, β-catenin activation, and downstream signaling pathways.

This review discusses various potential adverse effects of common oral vitamin and mineral supplements used in dermatology and highlights lesser-known issues like hematologic and neurologic effects from zinc.

This review discusses the role of diet in managing hair loss during menopause and reports no new clinical results; it highlights the importance of nutrients like sulfur amino acids, vitamins, and minerals.

This study demonstrated that water-soluble peptides from egg yolk, termed "hair growth peptide," stimulated human hair follicle cell growth and improved hair growth in female pattern hair loss.

This study found that pretreatment combining maceration with press-shear force and moist heat significantly increased the total phenolic and flavonoid contents in galactagogue herbs like banana inflorescences and Thai ginger.

This study concluded that Growth Factor Concentrate was more effective than Platelet-Rich Plasma in enhancing hair growth and patient satisfaction for individuals with androgenic alopecia and telogen effluvium, while maintaining similar safety.

This summary discusses the role of endocrinology and nutrition in skin health, highlighting the importance of a balanced approach to UV exposure, nutrition, and potential benefits of probiotics without reporting new research findings.

This review discusses the role of nutrients in hair graying management and finds a possible link between low copper, iron, and vitamin B12 levels and premature hair graying.

This study found that epidermal and fibroblast growth factors increased proliferation of human hair bulb papilla cells and root sheath fibroblasts in vitro, while hydrocortisone decreased it and minoxidil had no effect.

In this study, researchers found that the variability in growth factor expression, particularly TGFβ1, in PRP samples could influence patient responses to hair loss treatment with PRP therapy.

In this study of 60 patients aged 1 to 60 with clinically diagnosed scalp diseases, researchers identified age, sex, educational level, occupation, socio-economic condition, family history, and behavior as factors associated with the prevalence of these diseases.

This review discusses how changes in hair and skin may indicate underlying vitamin deficiencies and emphasizes the need to identify populations at risk for these deficiencies; it reports no new results.

This review discusses how acute exposures to environmental and internal stressors can quickly alter skin functions, leading to various dermatological symptoms, and calls for more research on these short-term effects.

This study found that NFI-C plays a crucial role in the transition from the telogen to anagen phase of the hair follicle cycle, affecting hair growth initiation in mice.

This article explores how various nutrients and metabolic processes impact wool and hair follicle function in animals but reports no new experimental findings.
