Difference between batik and ordinary hair dyeing

1, the principle is different: ordinary hair dyeing belongs to the use of hair dye, so it belongs to a chemical reaction. The principle is that some substances are used for redox, which directly changes the content of a pigment in hair and achieves the effect of dyeing hair; Batik is actually a physical reaction, which absorbs hair through a colored substance, thus blocking the original color of hair and achieving the effect of dyeing hair.

2, damage to the hair: Because batik needs to apply wax to the hair, it will cause more damage to the hair than ordinary hair dyeing; Ordinary hair dyeing is relatively mild and will not cause too much burden and harm to hair.
