Can hair dye cause cancer?
The association between hair dye and cancer has been a focus of research. Certain components of hair dyes are classified as Group 3 carcinogens, on par with coffee. Studies suggest that long-term exposure to hair dyes may increase the risk of certain cancers.
How to choose hair dye?
When selecting hair dye, you should pay attention to the ingredients and choose products suitable for your hair color. Experts recommend avoiding dyes that advertise "quick dyeing, dark colors, long-lasting effects," as these may contain chemicals like para-phenylenediamine (PPD). Choosing products with a licensed identification number and complete labeling, and ensuring correct usage, are important steps in reducing risk.
How to avoid cancer risks from hair dye?
- Reduce the frequency of dyeing, recommend intervals of 3 to 6 months, and conduct a skin test before use to prevent allergies.
- Drink plenty of water after dyeing to maintain hydration, which helps reduce risks.
- Maintain healthy lifestyle habits, such as a balanced diet and proper exercise, to lower overall cancer risk.
- Use hair dye correctly, avoiding contact with the scalp, and pay attention to the condition of the skin after dyeing to prevent risks.
