This study found that the medulla of Japanese hair contains unsaturated lipids such as squalene and oleic acid, which may contribute to hair glossiness.

This study observed that a combination of micro-needling and low-level light/laser therapy significantly increased hair density in patients with mild to moderate androgenic alopecia, showing an increase of 12 hairs/cm² after 16 weeks, compared to baseline.

This review discusses the mechanisms of hair repigmentation and reports no clinical results; the authors suggest further research into topical treatments for reversing gray hair.

This review found that anti-aging peptides show promise in cosmeceuticals due to their targeted actions to rejuvenate skin, but challenges like peptide stability, penetration, and limited clinical data limit their current effectiveness.

This bibliographic review highlights the importance of microneedling as a dermatological technique for treating androgenetic alopecia, emphasizing its potential benefits and the need for personalized treatment by skilled dermatologists.

This case report observed that a 44-year-old male patient with androgenetic alopecia experienced increased hair density and patient satisfaction after treatment with microneedling, growth factors, and minoxidil.

Hair growth is influenced by factors like genetics and nutrition, and more research is needed to understand hair loss and growth mechanisms.

In this article, researchers explore the causes, diagnostic approaches, and treatment strategies for diffuse telogen alopecia, emphasizing the importance of identifying triggers such as stress and metabolic disorders to effectively manage this hair loss condition.

Among maize plants, this study observed that root hairs tend to grow in air-filled pores at the root-soil interface, but their growth into the soil matrix is limited, posing potential constraints on nutrient uptake, anchorage, and rhizosheath formation.

The herbal hair serum with rosemary, hibiscus, and neem is safe and effective for hair care.

This ex vivo study found that hair follicles in female pattern hair loss exhibited nutrient insufficiency and dormant metabolism, but maintained nutrient uptake capability, suggesting potential benefits of nutritional supplementation as an adjunct therapy.

This study found that the maternal nutritional status during early pregnancy significantly influenced epigenetic changes in offspring, as maternal diet altered DNA methylation at human metastable epialleles.

This review discusses environmental factors like UV radiation and smoking that affect hair health and highlights the potential role of nutrition, but it reports no new results.

This article recommends assessing serum ferritin and vitamin D levels in patients with diffuse hair loss before starting treatment, but it reports no new clinical results.

This article discusses the dual nature of selenium, highlighting its essential metabolic roles and potential toxicity at high doses, and reports no new experimental findings.

This perspective proposes a new classification system for "superfoods" to better align them with environmental and social sustainability goals, emphasizing plant-based sources over animal-based ones due to lower greenhouse gas emissions and deforestation impacts.

This study concluded that rosemary essential oil rich in terpenes was successfully extracted using vacuum-assisted hydrodistillation, and Solid Phase Micro Extraction was superior for identifying volatile compounds compared to direct injection.

In this study, the combination of arsenic toxicity and hypoxia in Arabidopsis thaliana altered root development through stress-specific root growth phenotypes and changes in phosphate starvation response, energy metabolism, and redox signaling.

This study suggests a link between hair loss experienced during pregnancy and lactation and inadequate daily intake of certain nutrients.

This review explores the mechanisms, current products, challenges, and innovative approaches related to cosmetics for hair loss prevention and growth promotion, emphasizing the need for multidisciplinary cooperation to enhance product development and market success.

This case study observed that high-intensity focused ultrasound treatment significantly improved hair density and reduced hair loss in a female patient with androgenetic alopecia, with no adverse events reported.

This review examines the mechanisms of hair follicle development and regeneration, discussing current hair loss treatments and emerging therapies like low-level laser therapy and stem cell therapy, which the authors suggest show promise in managing hair loss.

In this study, researchers showed that the CAP1 gene regulates root hair growth in plants by modulating cytoplasmic ammonium levels and maintaining calcium gradients, highlighting its role in ammonium homeostasis.

This review explores the effects of caffeine on cancer, cardiovascular, immunological, inflammatory, and neurological diseases, including its use in sports, and discusses advancements in caffeine delivery through novel nanocarrier-based formulations.

This study found that hair treated with a supplemental hair care product showed significantly higher absorption, deeper penetration, and reduced dryness compared to untreated and water-treated hair, as measured with 3D Raman spectroscopy.

This study observed that maize plants, including a root hairless mutant variety, did not exhibit typical root growth or compensatory foraging behavior under severe boron deficiency in soil, indicating atypical responses compared to other plants.

This article discusses the formulation and potential benefits of herbal hair gels, highlighting their moisturizing properties and fewer side effects compared to marketed synthetic alternatives, but reports no experimental results.

This review examines nutritional deficiencies after bariatric surgery, particularly in essential minerals like zinc and copper, and highlights the need for more research to improve post-surgery nutritional outcomes.

Hair from different ethnic groups affects soil nutrient release differently.

This study found that root hairs of wild-type Arabidopsis grow faster and longer under low potassium stress, with changes in actin filament dynamics and specific regulation by the actin bundling proteins VLN1 and VLN4.
