Love this brush I found at Sally's for around $7.00. It does seem to actually add a bit more shine to my hair (I use it while blow drying.)
From Sally's website: "Tourmaline is a natural source of negative ions & far-infrared heat that eliminates frizz. Seals the cuticle layer locking in moisture, creating a sleek, shiny finish. Far-infrared heat penetrates the hair from inside out resulting in a faster drying time with less damage. Nylon bristles are gentle to hair and creating a soft scalp massage. Speeds up drying time by allowing heat to penetrate the Thermal Vented Ceramic barrel
Negative Ion Energy™ is a blend of Tourmaline and 30 Super-Moist Ceramic Minerals that creates silky, smooth hair. Far-infrared heat penetrates the hair from inside out resulting in a faster drying time with less damage. Hair is left looking smooth and shiny and frizzies are virtually eliminated. ION Ceramic Round Brush's nylon bristles are gentle enough to protect hair from breakage and massage the scalp."

The brush is light, easy to handle, doesn't catch my hair at all = I would re-purchase.
