The Efficacy of Gastrodia Elata Blume (GEB) Extract through Chemical Repetitive Treatment of Hair

This study used GEB extract to minimize hair damage during chemical hair treatment. For this, changes in the severity of hair damage through an addition of GEB extract (20%) during hair coloring after a perm or during a perm after hair dyeing were examined. After dyeing hair after a perm (PDO), dyeing after a GEB extract-added perm (PDT), GEB extract-added dyeing after a GEB extract-added perm (PDTH), a perm after GEB extract-added dyeing (DPO) and GEB extract-added perm after GEB extract-added dyeing (DPT), the study found the following: In the formation of a perm wave, DPT was the highest with 38.63%. In terms of tensile strength, PDTH was the highest with 157.51 gf/㎟. According to an analysis of cuticles, clear and even scale formation was observed in PDTH. In terms of microscopic structure, stable scales were found in PDTH (284.22 ± 29.51 ㎚). In terms of formation of amino acid, PDTH reached up to 78.75%. In terms of cysteine content as well, PDTH was the highest with 7.628. In terms of color, L*, a* and b* values all declined in PDTH. It was verified that if GEB extract-added dyeing is performed after a perm during a chemical hair treatment, hair damage can be reduced. Therefore, it appears that GEB extract would be useful in the cosmetology industry.
