When Brenda visited Afrodita, her existing color was fading and growing out. As you can see, her hair was getting a darker feel to it, and she wanted it brightened up.
Yoshiko treated the roots and gave her highlights all around. Along with this, the hair was trimmed up, and Brenda was given side bangs.
Her locks now sweep over the front of her face and give off an asymmetric look.
The end result is her hair looks to have more volume, and is a more vivid color than when she came in.
