    TLDR TRP-hair essence protects hair from heat damage, maintains color, and strengthens hair.
    The study evaluated the protective effects of TRP-hair essence, containing alpha-tocopheryl acetate, retinyl palmitate, and phytantriol, on human hair. Involving 20 female subjects aged 19-59, the results showed that TRP-hair essence significantly reduced protein leakage by 32.61% (p <0.001) and improved tensile strength by 23.23% (p <0.05) after heat stress. It also enhanced color persistence of dyed hair and improved cuticle quality by 18.25% (p <0.05) after repeated heat treatments. These findings suggest that TRP-hair essence effectively protects hair from heat damage, maintains color, and strengthens hair.
