What are some side effects of hair dye?
Hair dyes can trigger minor to severe allergic reactions.
They can also cause dry, brittle hair and hair breakage with extended and frequent use.
According to the American Cancer Society, the evidence linking personal hair dye use and cancer is limited and conflicting.
Personal use of semi-permanent and permanent hair dyes is not considered a known risk factor for cancer.
American Cancer Society, have suggested that exposure to hair-dye chemicals can lead to a slightly elevated risk of bladder cancer.
So, ultimately the risk factor for cancer stays on.
The chemical paraphenylenediamine, a common ingredient in hair dyes causes allergic affects.
Common allergic reaction to hair dyes may present itself as an itchy, red rash around the face and neck, and less commonly a rash on the scalp and extreme swelling of the face.
