The general hair dye can be divided into 4 categories: temporary hair dye, gradual hair dye, semi -permanent hair dye, and permanent hair dye. Temporary hair dyeing agents will only leave the surface of the hair. Use shampoo to wash this type of dye, so temporary hair dye is usually harmless. Gradual hair dye is a metallic dye. Most of them contain lead, sulfur and other ingredients, and need to be applied to the hair every day. These metals are gradually deposited on the hair to turn the hair color. Because this type of hair dye is like cream and can replace oil, it is almost clear that men are using it. In 1980, the U.S. Drug Administration announced that such products were safe to users. However, recent research showed that the lead in these hair dyes could cause the pollution of furniture and affect the safety of young children. Therefore It is necessary to be careful to avoid lead poisoning.
The dye molecular amount used in semi -permanent hair dyeing agents is small, which can penetrate the hard keratin of the hair and cause changes in hair color. Washing out, but it can usually resist more than 12 shampoo without fading.
Permanent hair dye enters the hair center through colorless first, and then causes permanent hair color changes through oxidation.
