Frequent hair coloring is not 100% cancer, but frequent hair colorers are at high risk of certain cancers. Because hair dye contains a lot of harmful chemicals, frequent hair dyeing will lead to the accumulation of toxic chemicals in the body, causing DNA breakage, oncogene activation and inactivation of oncogene, which will eventually lead to the occurrence of malignant tumors. People who frequently dye their hair are prone to the following cancers, mainly blood tumors, such as acute leukemia, including acute myeloid leukemia and acute lymphoblastic leukemia, as well as myelodysplastic syndrome, lymphoma, and aplastic anemia. In addition, people who frequently dye their hair are also prone to skin cancer due to long-term exposure to toxic chemicals.
