There are a handful of us dry shampoo junkies over here at D, so dry shampoo is always a hot topic. Here’s a new one to try: Jonathan Product’s Green Rootine Dry Shampoo Brush On Hair Powder. It is, as I bet you guessed, a hair powder that comes in a brush. It’s the perfect travel companion because you pop off the lid, push the covering down to expose the blush brush, turn the knob to open the desired amount, and dab away at your greasy hairline until you can no longer see your reflection. The powder comes in two colors, light and dark, and is exclusively at Sephora for $19 0r online at the Jonathan Products site. Brilliant!
