Does Frequently Dyeing Your Hair Really Cause Cancer? (151 words) Aunt Wu, 55, had been dyeing her hair to cover up the increasing amount of white hair that comes with aging. One day, she dyed her hair a new color and eagerly showed her husband. However, this led to a big argument between the couple.

There has been a long-standing debate on whether dyeing hair can cause cancer. A study conducted by researchers from Brigham and Women's Hospital at Harvard Medical School offers some insight. The study followed 117,000 female participants for 36 years and found no significant increase in the risk of most cancers associated with frequent use of permanent hair dye.

However, there was a slight increase in the risk of breast cancer, ovarian cancer, and basal cell carcinoma among women who dyed their hair 200 or more times compared to those who never dyed their hair. While there is no definitive proof that dyeing hair causes cancer, there are risks associated with excessive use of hair dye, such as allergies, heavy metal poisoning, damage to hair quality, and liver damage.

To minimize the risks, it is important to choose qualified hair dye products, carefully read the instructions, conduct allergy tests, and avoid frequent dyeing.
