The bristles feel extra gentle on your scalp due to the unique elastomeric bristle-base which absorbs the impact of the brushstroke. The ergonomic brush design efficiently reduces the amount of brushstroke required. The nylon bristles penetrate and hold any hair texture, whilst the boar bristles smooth the hair shaft. Boar bristles are known for evenly distributing your hair's natural oils throughout the hair to add shine, leaving the hair silky smooth. Patented.
