She came in wanting a brighter brunette, but her inspo had a naturally lighter base.

So instead of chasing the photo, we adjusted the approach—more contrast, strategic highlights, and richness in all the right places.

This is what happens when you work with your natural depth instead of against it.

For my darker brunettes—you don’t need to go blonde to feel brighter.
