The Flex Brush XL Black Mixed Bristle is a professional-grade, oversized detangling and styling tool designed to contour to the unique shape of your scalp. By combining natural boar bristles with flexible nylon pins, it provides a dual-action benefit: smoothing the hair and distributing natural oils while gently working through stubborn knots. Contouring Flex Technology: The brush head is engineered to bend and flex as you brush, maintaining maximum contact with the scalp to provide a soothing massage that stimulates blood circulation. Mixed Bristle Design: Features humanely harvested boar bristles to enhance shine and reduce frizz, alongside flexible nylon pins that detangle wet or dry hair without snagging or breakage. Vented for Heat Styling: The open-vented design allows for superior airflow during blow-drying, significantly speeding up drying time and minimizing heat damage. Professional XL Size: At approximately 9.25 inches long and 3.25 inches wide, the XL model offers greater surface area coverage than the "Petite" version, making it ideal for long, thick hair or extensions. Gentle on Scalps: The flexible frame and soft bristles are highly recommended for those with sensitive scalps, as they release knots gently rather than tearing through them.
