Yes, Jennie has dyed her hair.
Jennie, a member of the popular K-Pop group Blackpink, is known for her style and has experimented with her hair color. While she's often seen with her natural dark brunette hair, she notably dyed her hair a peachy-orange color in April 2022. This change was considered significant as it was one of the biggest hair transformations she had undertaken since 2019.
Therefore, it is confirmed that Jennie has dyed her hair at least once.
