Before that, there was an investigation into the relationship between hair dye and cancer in the United States. 120,000 female nurses were followed up, mainly studying hair dye frequency, whether they have cancer, exercise volume, food intake and other information. After 36 years of follow-up investigation, 20,000 female nurses suffered from cancer, 23,000 female nurses suffered from basal cell epithelioma, and nearly 5,000 years of death from cancer.

After research and analysis, the experimenters analyzed the probability of various cancers. The results showed that hair dyes may cause people to suffer from base cell epithelioma, breast cancer , ovarian cancer, etc., 2% to 30%, but may reduce the risk of brain and lung cancer.

The United States' 36-year-old experiment concluded that hair dye may not be carcinogenic. Others have also conducted the same statistics. According to the expert's explanation, different experimental analyses and experimental analysis of mice, concluded that hair dye has a certain carcinogenicity, because some chemical components in hair dye will destroy the body's immune system. The phenylenediamine (carcinogenic substance) in hair dye will cause great harm to hair, resulting in hair loss and rough hair.
