This study reports that the fatty acid composition in cell membranes of stratified squamous epithelium varies with keratinization patterns, showing a partial essential fatty acid-deficient state in cultured keratinocytes.

This study provides conclusive evidence of exogenous calcium fatty acid deposits forming between the cuticle layers in hair, affecting its optical and mechanical properties.

This study's simulations suggest that replenishing free 18‐MEA could restore damaged hair surface properties, highlighting the importance of optimal fatty acid spacing for maintaining hair integrity.

This study observed that feeding ewes a water-soluble complex of fatty acids increased primary hair follicle bulb diameter and mitotic activity, suggesting a positive correlation with wool growth.

This study found that chemical treatments such as hair bleach and UV radiation significantly reduced the amount of 18-methyleicosanoic acid on the outer surface of human hair.

This study used molecular dynamics simulations to illustrate the complex molecular behavior of the hair surface F-layer, highlighting how fatty acids interact with 18-MEA under different conditions.

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.

Hair fibers interact through classical forces, which are influenced by treatments and products, important for hair care and other applications.

This study found no conclusive evidence of biocatalytic activity of guinea pig liver transglutaminase with virgin human hair, potentially due to a fatty acid layer on the hair surface.

This study concluded that bleach treatment partly transforms the hydrophobic top layer of human hair cuticles into a hydrophilic surface with clustered cysteic acid, visualized at the nano-scale using dynamic Chemical Force Microscopy.

This study found that ceramide-based essence cream, particularly those with stearyl and stearyl-cholesterol, improved the ultrastructure of damaged hair cuticles.

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.

In this study, researchers found that UV radiation causes hydroxy radicals to form cuticle holes specifically between the cuticle layers in wet hair, unlike random holes caused by Fenton's reaction.

The study concluded that fatty acid transport protein 4 in epidermal keratinocytes is crucial for maintaining normal skin structure, as its deficiency led to hyperkeratosis and epidermal barrier disruption in mice.

This review discusses the integration of omics analyses in androgenetic alopecia research, reporting no new clinical results but suggesting that collaborative multi-omics studies may enhance understanding of AGA's pathomechanisms.

This study identified an unexpected critical role for the FATP4 protein in skin and hair development in mice, linking it to a potential candidate gene for restrictive dermopathy in humans.

This study revealed that deficiency in the enzyme FA2H in mice affected sebaceous gland function, altered sebum composition, and caused cycling alopecia, highlighting FA2H's role in hair follicle homeostasis.

In this study, periodic exposure to red light in aged mice led to increased histone acetylation and activated mitochondrial fatty acid oxidation, which collectively mitigated cellular aging by modulating metabolism, inflammation, and gene expression.

This study found that in genetically diabetic mice, supplementation with safflower or evening primrose oil prevented the decrease in certain fatty acids and improved skin conditions, but increased plasma glucose levels.

This study suggests that 9-Octadecenoic acid (Z)-, 2,3-dihydroxypropyl ester from African Yam bean seeds may inhibit the human 5α-reductase II enzyme, potentially helping manage BPH, although further studies are needed.

This study reports that polyphenols from Annurca apples may safely promote hair growth and protect against chemotherapy-induced alopecia without interfering with chemotherapy regimens.

This study reported that nanoemulsions significantly improved the skin permeability of thiocolchicoside compared to its aqueous solution, suggesting they are effective carriers for its transdermal delivery.

Azelaic acid may help treat acne by killing bacteria, reducing inflammation, and preventing clogged pores.

This study identified that the enzyme CYP2B12 is skin-specific and likely plays a role in the metabolism of arachidonic acid, a key component in lipid signaling within sebaceous glands.

In this study, knockout mice lacking the Cyp4f39 gene showed severe skin barrier dysfunction and high early mortality, suggesting its critical role in skin barrier formation and insights into ichthyosis pathogenesis.

This review explores the role of fatty acids and bioactive lipid mediators in skin health and suggests targeting this metabolic network to control inflammation and improve skin conditions, but it reports no new findings.

This study found that unsaturated fatty acids are more abundant in the cortex of human hair than on its surface, and steryl glycoside-like lipids may help bind the cuticle to the cortex.

This research proposes to investigate the incidence of skin diseases in dogs from North-eastern India linked to deficiencies in alpha-linolenic and linoleic acids, as these essential fatty acids have anti-inflammatory and immunomodulatory benefits potentially aiding inflammatory skin disease therapy.

This study found that the application of polyunsaturated fatty acids, particularly arachidonic acid, promoted hair growth and anagen induction in both human dermal papilla cells and mouse models.

This study found that blue laser irradiation reduced ATP levels and cell viability in mouse skin by increasing oxidative stress through the production of reactive oxygen species.
