This study investigated lipid loss in hair caused by surfactants and found that surface and internal modifications can significantly protect different lipids from depletion, with internal modification preventing 52.0 to 81.3% of lipids in certain groups.

This study found that menopause alters hair lipids and reduces hair quality, with hormone replacement therapy mitigating some changes.

In this study, researchers found that higher concentrations of internal lipids in African hair may influence its keratin structure, as observed through various analytical methods.

In this study, researchers identified a three-step process underlying age-related curved hair from cyclical extension: surface lipid transfer, specific disulfide bond cleavage, and unraveling of α-helices into β-structures, which may inform care strategies to manage hair curvature.

This study found that shampoo and conditioner do not alter hair's molecular structure, while perming treatments significantly affect keratin and intermediate filament structures due to bond alterations.

This study found that lipid extraction increased water diffusion in wool and hair fibers; the effect was more pronounced in hair, indicating lipids are crucial for water permeability.

This study found that cationic lipid-based formulations enhanced the delivery of large molecules into hair follicles in human scalp skin, with potential to reach pharmacologically active concentrations in the hair bulb.

In this study, the use of internal wool lipid liposomes was shown to improve the lipid composition and increase the resistance to breaking in both untreated and chemically treated hair fibers.

In this study, extracting internal lipids from Caucasian hair fibers led to decreased water permeability, influenced by the fluidity of lipids.

In this study, researchers found that the lipid composition in hair significantly affects water diffusion and may explain differences in dyeing and cosmetic treatment responses between Asian and European hair, with CP2 fibers having more lipids than CP3 fibers.

This study found that bioconjugating 16-methylheptadecanoic acid to damaged human hair can mimic the protective function of the original 18-methyleicosanoic acid, effectively restoring both the hair's external structural integrity and its internal moisture balance.

This study reports a solid causal relationship between increased serum levels of ApoB, LDL, and VLDL and an elevated risk of androgenic alopecia.

This study observed that in Japanese females, hair lipid composition showed significant correlations, suggesting CH and CERs may act as a barrier against sebum-derived lipids.

In this study, researchers identified two mechanisms of lipid loss from hair when exposed to surfactants, with the mechanism depending on the lipid's hydrophobicity.

In this study, HIIT increased adiponectin levels and improved cholesterol profiles in women with PCOS, but did not change leptin or vaspin levels.

This study found that while molecular hair structures were nearly identical across individuals, genetic factors seem to influence specific lipid compositions, as seen in identical-patterned hair from parent-child pairs and identical twins, but not fraternal twins.

This study found that the hair interior defect in AKR/J mice is linked to a mutation in the Soat1 gene, which disrupts SOAT1 protein expression and affects lipid metabolism critical for normal hair formation.

This study highlights the potential of cosmetic products combining fibroblast growth factors and antioxidants like thioproline, ergothioneine, silymarin, and rosmarinic acid, to mitigate skin aging by reducing oxidative stress and enhancing cellular protection in the skin.

The document concludes that scalp health is influenced by complex factors affecting sebaceous glands, including hormones, aging, and various substances.

This study found that wool felting in Ukrainian Carpathian Mountain sheep is linked to significant changes in fatty acid composition, particularly highlighting a decrease in 18-methyleicosanoic acid in bound lipids, suggesting it as a potential marker for cuticle lipid layer damage during felting.

This review explores both traditional Ayurvedic uses and modern scientific findings on Japa Pushpa (Hibiscus rosa-sinensis), suggesting it may benefit cardiovascular health and metabolic balance as a herbal tea, but emphasizes the need for further clinical validation.

This article reviews the role of skin surface lipid in mediating environmental stressors and discusses potential therapeutic interventions, reporting no new experimental findings.

This study developed solid lipid nanoparticles for effective delivery of shRNA-encoding plasmids, showing reduced 5α-reductase levels in DU-145 cells without significant cytotoxicity.

This review discusses the efficacy of the lipidosterolic extract of Serenoa repens for treating lower urinary tract symptoms and reports no new clinical results; the authors propose further examination of the existing literature and guidelines.

This review concludes that global literature supports the lipidosterolic extract of Serenoa repens as efficacious and safe for treating lower urinary tract symptoms, with some studies showing equivalence to common pharmacologic agents.

This study found that abnormal serum lipid levels were prevalent among male patients with androgenetic alopecia, with high triglycerides and low HDL observed frequently.

This article examines the role and composition of integral hair lipids in forming a protective barrier similar to the skin's epidermal lipid layer and reports no new findings about their effects.

This study found that in Japanese, German, and American females, changes in hair lipid patterns with age may reflect alterations in sebum excretion and affect hair texture.

This study found that African and Caucasian hair contain the most lipids, and depletion of these lipids leads to less water retention and increased water desorption, with Caucasian hair showing improved breaking tenacity after lipid extraction.

This study found that mice lacking myelin protein zero-like 3 (Mpzl3) had reduced body weight and adiposity despite increased food intake, which was linked to higher energy expenditure and improved glycemic control.
