No. 2: A boar bristle brush Both Potempa and Jennifer J. love Mason Pearson boar bristle brushes because they "can create a perfect, sleek ponytail or a full, voluminous wave," Potempa says. But if you think the $170 price tag makes baldness sound appealing, rest assured that there are more affordable alternatives. Try the Denman Groomin Brush with Natural Boar Bristles & Nylon Pins, $15.99. It has a mix of natural boar bristles and nylon just like the Mason Pearson, but is a fraction of the price.
