BY Ina Barton 2018-06-02P-phenylenediamine in hair dyes can cause skin irritation and even cause cancer. If you need to heat your hair when dyeing it, it is more harmful to your health, because after heating, p-phenylenediamine will enter the capillaries through the scalp, and it may cause blood diseases such as leukemia with blood circulation. In addition, p-phenylenediamine is also susceptible to skin cancer and bladder cancer.3
