I wasn't planning on buying an new brush but this one tempted me from the drug store aisle. The hair-enhancing properties of crushed tourmaline have been well-documented in the past few years and many companies have created hair dryers and flat-irons involving the gem. Tourmaline is piezoelectric and when crushed it releases negative ions which have a beneficial effect on hair, increasing shine and minimizing brittleness. This is the first time I have seen a brush using the gem before so I had to buy it and test it out. The verdict? I didn't notice a big difference in just brushing my hair with it. I brushed one side of my hair with a regular brush and one side with the tourmaline brush. I couldn't tell them apart. I did notice that when I used it with a dryer my hair did appear to be a little shinier and softer but not so much so that I might not have just imagined the increased shine. Either way, it's still a decent hairbrush and I dig the snappy red color, it matches my toes. The brush sells for around $8.
