Thai Health Officials Say No Proof Hair Dye Causes Cancer
Thai health officials say no conclusive evidence links frequent hair dye use to increased breast cancer risk, though allergic reactions remain possible.
Check the risk! Does frequent hair dyeing really cause cancer? Revealing hair dye allergy symptoms — anyone with these signs must be careful.
Many people dye their hair regularly, whether to cover grays, for beauty, or to boost confidence. With fashion hair color trends changing yearly, some change colors nearly every month, raising concerns about chemical dangers from hair dyes.
Hair dye is the product commonly used to change hair color. Its ingredients consist of various chemicals mixed together.
How many types of hair dye are there? Hair dye products generally sold in the market can be divided into three types:
Temporary hair dye: The color coats only the outer hair shaft, does not penetrate the cortex, washes out easily, and fades within 1-2 washes. Suitable for temporary color changes or trying new shades. The color molecules are large, coating the outer hair shaft. Examples include color rinses, hair crayons, and color sprays.
Semi-permanent hair dye: Color lasts up to 5-6 weeks. Contains no bleach or ammonia. Suitable for those wanting color change without excessive hair damage. Smaller molecules penetrate the middle hair layer. Examples include color-depositing shampoos, lotions, and foam dyes.
Permanent hair dye: Permanent color change; must wait for new hair growth. Contains ammonia and hydrogen peroxide. Suitable for covering gray hair or permanent color change. Color adheres permanently to hair shafts, resistant to shampooing.
Does hair dye really risk causing cancer? Previous studies on hair dye health impacts found certain chemicals in some dyes increase health risks, stating "women who dye hair frequently face 60% higher breast cancer risk."
However, the National Cancer Institute, via Dr. Som sak Arongrat, Director-General of the Department of Medical Services, fact-checked and found no conclusive research evidence confirming women who dye hair frequently face higher breast cancer risk. Still, using hair dye with safety precautions helps reduce risk of chemical-related diseases.
Even though no research conclusively proves hair dye is a human carcinogen, hair dyes contain multiple chemicals that may cause allergic reactions in some people.
Hair dye allergy symptoms: - Red rash, itchy scalp - Swollen skin, eyes, mouth, tongue, hands, feet; blisters or peeling - Wheezing, difficulty breathing - Abdominal pain - Nausea, vomiting - Dizziness, fainting
Choosing hair dye: Select standardized safe products. Wear gloves or protective gear during dyeing to minimize chemical contact. If allergic reactions occur, stop using immediately and see a doctor.
