Bigen Men’s Speedy Hair Color in Natural Black offers a quick and convenient solution for men looking to achieve a natural black hair color. This easy-to-use hair dye comes in a 80g pack and is designed specifically for men's hair. The key active ingredients in this hair color provide long-lasting color coverage while also nourishing and conditioning the hair. The mechanism of action involves penetrating the hair shaft to deposit color molecules, resulting in a vibrant and natural-looking black shade. This hair color not only provides a quick color change but also ensures a comfortable and easy application process. The creamy texture allows for smooth and even application, leaving the hair with a soft and natural finish.
