The Porcupine large boar-nylon cushion brush features both boar and nylon bristles. Boar bristles hold onto hair strands easily, but they are often soft and do not penetrate well. When combined with stiffer nylon bristles, the brush can easily penetrate the hairline. The white ball tips on this brush make it very gentle on the scalp. While brushing, this cushion brush will catch onto dead hair strands and help clean the head of dead hair. This brush is great for brushing out a variety of hair types. This superior quality brush is made in Germany out of the finest materials.
