"Azo dyes" can cause damage to the deoxyribonucleic acid in the cell nucleus and cause cell mutations, which is carcinogenicity and teratogenicity to the fetus. The harmful ingredients contained in hair dye are absorbed by the skin, enter the blood and spread throughout the body. The scalp hair follicles are the best channel for toxins to enter the human body. If hair dye is used for a long time, chronic accumulation will lead to malignant tumors such as bladder cancer, skin cancer, lymphatic system tumors, breast cancer, leukemia, etc. The toxic chemicals in hair dye need to be metabolized and excreted through the liver and kidneys after entering the human body, so long-term absorption will inevitably cause damage to liver and kidney function. It can also affect the bone marrow and cause aplastic anemia. The large amount of acid, alkali and other substances in hair dye can destroy the protein chains and amino acids of the hair, so the dyed hair will become dry, lose its luster and elasticity.
