    TLDR Scientists made human hair magnetic by coating it with special nanoparticles.
    The study successfully engineered human hair surfaces with polyelectrolyte-stabilized magnetite nanoparticles (MNPs), imparting magnetic properties to the hair. These nanoparticles, starting from cuticle gaps, spread over the hair surface, enhancing glossiness and allowing alignment under a magnetic field. The biocompatible and biodegradable MNPs suggest potential applications in topical drug delivery and hair care, such as controlling hair volume and reducing frizz. The research confirms the effective modification and stability of the nanoparticles on the hair surface, indicating significant advancements in multifunctional hair treatments.
