    TLDR The new polymer improves dyed hair's color, moisture, shine, and smoothness.
    The study evaluated a novel hybrid polymer composed of hydrolyzed protein, alkyl chain, and silicone for hair treatment. It was found to be effective in preventing discoloration of dyed hair and enhancing the moisture feel. The polymer demonstrated good substantivity, contributing to improved hair luster, manageability, smoothness, and combability, particularly in damaged hair. A sensory test with shampoo containing the polymer, even when highly diluted, supported these findings.

      A 37-year-old male has been using finasteride for 5 years and dutasteride for 9 months to address hair loss, noticing improvements but also some recent thinning. He experienced no significant side effects from either treatment, except a slight decrease in semen volume with dutasteride, and is considering trying oral minoxidil again despite previous side effects.
