Developed and patented more than 100 years ago. Mason Pearson's hair brush is the ultimate grooming tool. Only the finest. premium-grade boar bristle. which is gentle to the hair and scalp. is used. Brushing with a Mason Pearson hair brush is the best way to distribute the natural oils while exfoliating the scalp and stimulating circulation of the hair follicles. The patented pneumatic cushion conforms to the contours of the scalp. which optimizes brushing with minimal effort. All Mason Pearson hair brushes are handmade in England. The animals are not harmed in the collection of the boar bristles. A nylon cleaning brush is included. This mixture has a nylon 'spike' to facilitate brushing through thick. textured or wavy hair. yet may be used on all hair types.
