More use of hair dye products increase the risk of cancer
Please note that women who use permanent hair dye products. Researchers have found that permanent hair dye may slightly increase the risk of some types of breast, skin and ovarian cancer.
A Harvard University study in the US, published on Thursday in a journal called The BMJ, also revealed that natural hair color was also found to have an effect on the likelihood of certain cancers.
The use of hair dye is very popular, especially among older age groups eager to cover signs of gray. For example, it is estimated that it is used by 50–80 percent of women and 10 percent of men who are over 40 years of age in the US and Europe.
While the World Health Organization’s International Agency for Research on Cancer has classified occupational exposure to hair dye as a potential carcinogen, there is no warning about personal use because the current evidence is inconclusive.
To gain a better understanding of the risk of cancer with the use of personalized hair dye, researchers analyzed data from 117,200 women in the nurses’ health study, including assessing the risk of hair dye.
The women did not get cancer at the beginning of the study and were followed for 36 years.
The use of permanent dyes at times was associated with a slightly increased risk of basal cell carcinoma of the skin, and this risk was naturally higher in women with light hair.
The results increased the risk of three types of breast cancer – estrogen receptor-negative, progesterone receptor-negative, and hormone receptor-negative – and ovarian cancer was also associated with the use of permanent dyes, with increased risk according to cumulative . The amount of dye females were exposed to.
An increased risk of Hodgkin lymphoma was also seen with the use of permanent hair dye, but only for women with naturally dark hair.
The authors of the study stated, “The possible explanation could be that the colors of permanent hair dyes are associated with the concentration of the material, with darker colors being higher.”
However, the results showed that most women did not have an increased risk of cancer or death.
The authors also pointed to some limitations, including the lack of racial diversity of study participants and the possibility that other unheard factors, such as the use of other products, may also affect the results.
