Bur Bur's 192-titanium needle (0.3mm) derma roller is designed for ultimate performance in hair care. Lightweight and easy to use, it glides smoothly without tangling, while enhancing product absorption. Unlike the typical 540 triangular needle disk roller, theirs uses individual titanium linear needles for more precise and controlled micro-punctures. This allows for better scalp stimulation with less irritation, promoting healthier hair growth and delivering the best results.
