    Glossary 18-Methyleicosanoic Acid

    fatty acid crucial for hair's water-repelling outer layer

    18-Methyleicosanoic Acid (18-MEA) is a fatty acid that is a key component of the outermost layer of human hair. It helps to provide hair with its hydrophobic (water-repelling) properties, which protect the hair shaft from damage and maintain its natural shine and smoothness.
