This Mason Pearson B2 Extra Small Hair Brush is crafted with pure boar bristles, renowned for their superior ability to clean and condition the hair. The natural bristles distribute the scalp's oils (sebum) evenly down the hair shaft, promoting shine and health. Designed for finer hair types or for touch-ups on the go, the extra small size is highly portable. The iconic Mason Pearson design ensures long-lasting durability and ergonomic handling.
