Concerned about the potential cancer risks from the chemical ingredients in hair dyes, many people opt for products marketed as "plant-based dyes." But are these truly natural and harmless?
Dr. Chiu Pin-Chi, Director of Dermatology at National Taiwan University Hospital Yunlin Branch, explains that these so-called "plant-based dyes" often contain chemical additives. Pure plant-based dyes offer very limited color options and have short-lasting effects, making it difficult to meet consumer expectations. Dr. Chiu states: "Pure plant-based dyes can only produce a few colors, and the results are temporary. Frankly, achieving the shades preferred by Taiwanese consumers with pure plant-based dyes is very challenging. Many products claim to use ingredients like henna, coffee, or tea as dyes, but for long-lasting hair coloring, pure plant-based dyes simply can't deliver the desired results."
Dr. Chiu emphasizes that "plant-based dyes" are not entirely natural or risk-free. Whether plant-based or chemical, all dyes can cause some degree of damage to the hair. He advises the public to exercise caution when selecting and using hair dyes: avoid products of unknown origin, perform a patch test before dyeing, avoid applying dye to the scalp or skin, and seek medical attention immediately if redness, swelling, or allergic reactions occur.
