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.

research A Mixture of Tocopherol Acetate and L-Menthol Synergistically Promotes Hair Growth in C57BL/6 Mice

7 citations , December 2020 in “Pharmaceutics”

In this study, a mixture of tocopherol acetate, L-menthol, and stevioside was more effective in promoting hair growth in mice compared to tocopherol acetate or L-menthol alone.

research Heat Transfer in Human Hair

4 citations , June 2019 in “International Journal of Cosmetic Science”

This study developed mathematical models showing that heat penetrates individual hair quickly but takes longer to reach the center of hair bundles, helping understand potential damage from high-temperature styling tools.

research Changing the Shape of Hair with Keratin Peptides

47 citations , January 2017 in “RSC Advances”

Keratin peptides can change hair shape gently without harsh chemicals.

research Protein Loss in Human Hair from Combination Straightening and Coloring Treatments

18 citations , July 2015 in “Journal of cosmetic dermatology”

This study observed that combining hair dyeing with sodium hydroxide relaxers drastically increased protein loss in Caucasian virgin dark brown hair, while ammonium thioglycolate or guanidine hydroxide relaxers caused less damage.

research Comparative Study on Hair Protection Effects of Keratin Essence

2 citations , July 2013 in “Fashion business”
