    TLDR Future hair cosmetics will be safer and more effective.
    The review discussed the biology and biochemistry of human hair, focusing on the impact of cosmetic procedures like hair straightening and waving, which can irreversibly damage hair fibers by affecting their smoothness, porosity, shine, thickness, and mechanical properties. It emphasized the need for safer hair care treatments to prevent further damage and meet consumer demands. The review detailed the structure and composition of hair, the classification of hair shapes, and the differences in ethnic hair characteristics. It also covered the chemical processes involved in hair straightening, the potential adverse outcomes of cosmetic treatments, and the importance of proper product usage to minimize damage. Future advancements in cosmetic science were expected to develop treatments that safely control hair morphology and repair damaged hair.
