Over the last decades boar hair brushes have been used to create shiny, healthy hair without styling products. The natural properties of the boar hair bristles help to condition the hair by carrying sebum from the scalp to the end of the hair shaft. Sebum works like a natural anti-frizz serum that repairs dry hair and adds lustrous shine. The Silver Spa Brush features boar hair bristles and longer nylon bristles that stimulate the scalp and help to detangle the hair while allowing the boar bristles to distribute the sebum. Regular brushing with the Silver Spa Brush prevents oil build-up at the scalp which makes the hair look greasy, reducing the frequency of washing. It stimulates the scalp and increases the blood flow to the hair follicles, which can improve hair growth.
