Our brown hair color bar is carefully formulated with mineral fat, ethylhexyl palmitate and polyisobutylene. Designed specifically for forming a pigment adhesion layer to enhance the durability of coloring. The usage method is extremely convenient: clean the hair and keep it dry. Turn the knob at the bottom to obtain an appropriate amount of paste, then apply the product evenly to the hair and hair roots until the entire hair is covered. And it can adopt a sturdy design. Without additional tools, it can be applied with just a light touch for coloring. The operation is simple and requires no experience.
