Fundamental Hair Chemistry for the Undergraduate Classroom - Anuradha Liyana Pathiranage

Fundamental Hair Chemistry for the Undergraduate Classroom�reveals human hair as an unexpectedly powerful model for teaching core chemical principles. By connecting everyday practices�- colouring, bleaching, straightening, perming and shampooing�- to the molecular reactions behind them, the book transforms familiar beauty routines into rich opportunities for learning. Students encounter organic mechanisms, redox chemistry, lipid science and formulation concepts through relatable, real-world examples. The text guides readers through the structure of hair and the chemistry that shapes its behaviour, from melanin oxidation during bleaching to the redox reactions behind permanent waving and relaxing. Natural, semi-permanent and oxidative dye systems illustrate electrophilic addition, coordination chemistry and in-fibre polymer formation, while lipid composition and surfactant science deepen understanding of surface chemistry and formulation design. Each topic reinforces foundational concepts by grounding them in authentic scientific applications using cosmetics. Designed for upper-level undergraduates and educators, this book blends mechanism-driven explanations with hands-on activities that bring chemical theory to life. By uniting diverse areas of chemistry, within a culturally relevant and scientifically rich context, this book fills the gap between traditional textbooks and industry-focused cosmetic science. The result is a compelling demonstration that chemistry is woven through everyday life and that even a single strand of hair can illuminate the molecular world.
