The Anastasia Beverly Hills Dual Ended Firm Detail Brush is an essential tool designed for precise application and blending of eyebrow products. Its dual-ended feature offers versatility, allowing you to define and sculpt brows with accuracy. One end features firm, densely packed bristles perfect for creating sharp, detailed lines and filling in sparse areas with pomades or powders. The opposite end typically houses a spoolie brush, ideal for softening harsh lines, blending color evenly, and grooming hairs into place for a polished, natural finish.
