In this post, I'm showing photos of what koolaid looks like on brown hair that has not been lightened. Photos will be updated as more dye jobs are done.

These dye jobs were done on real human hair extensions, since I don't actually have brown hair growing out of my head. This is real human hair, nonetheless, so it's a great representation of what you'd see with your own hair if it's close to this color.
