Dyeing hair can make people beautiful, but certain hair dyes may hide cancer risks, especially instant, dark, or permanent products. It is very important to choose the right dye and use the correct method. The International Agency for Research on Cancer has classified some ingredients in hair dyes as Group 3 carcinogens, and long-term use may increase the risk of certain cancers. When selecting, pay attention to the ingredients, avoid products containing chemicals like para-phenylenediamine, and choose licensed products. To reduce risks, it is recommended to lower the frequency of dyeing, drink enough water, maintain a healthy lifestyle, and use hair dye properly.
Everyone wants to have beautiful hair color, but did you know? Some hair dyes may have cancer risks! Especially those products that claim to be fast-drying, dark-colored, and long-lasting carry a higher potential risk. To stay beautiful and safe, it's essential to choose the right dye and use it correctly. Let's learn how to reduce these risks together!
Can hair dye cause cancer?
The association between hair dye and cancer has been a key focus of research. Certain hair dye ingredients have been classified as Group 3 carcinogens, which is the same level as coffee. Some studies show that long-term exposure to hair dye may increase the risk of certain cancers.
How to choose a hair dye?
When selecting hair dye, pay attention to the ingredients and choose products that are suitable for your hair color. Experts recommend avoiding dyes labeled as "fast-drying, dark-colored, long-lasting," as these products may contain chemicals like para-phenylenediamine (PPD). Choosing products that have a licensed number and complete labeling, and ensuring correct usage methods, are important steps to reducing risks.
How to avoid cancer risks from hair dye?
- Reduce the frequency of dyeing; it is recommended to do it once every 3 to 6 months, and perform a skin test before use to prevent allergies.
- Drink plenty of water after dyeing to stay hydrated, which helps reduce risks.
- Maintain a healthy lifestyle, such as a balanced diet and proper exercise, which can lower overall cancer risk.
- Use hair dye correctly, avoiding contact with the scalp, and monitor skin condition after dyeing to prevent risks.
