If you don't want to go the more colorful route when it comes to your NuBrush of choice, you'll likely just want to get the plain 'ole Nu Brush black edition. It does the same job as its more colorful counterparts, of course, meaning it will help to revitalize your scalp and remove dandruff - but instead of being colored, it's simply black. It's great for shower usage as well to scrub off the dead skin. There are a dozen included here.
