CONCLUSION
OXIDATIVE STRESS
The oral consumption of PLE formulated with green tea and Sophora fruit extracts showed significantly increased hair density and thickness compared to the control group, showing its possible role in promoting hair growth. Although not statistically significant, the degree of hair gloss in the test group after the oral consumption of BLH308 was also increased compared to that of the control group. As the mechanism involving skin tissue injury caused by extrinsic factors revolves primarily around the installation of oxidative stress, the antioxidative and anti‐inflammatory activities of PLE along with green tea and Sophora fruit extracts could be the major factors resulting in the general improvement of hair health. Further clinical studies with the test product applied to participants with photo‐aged scalps will be necessary to confirm its role in oxidative stress induced by extrinsic aggregations.
