Hair Dyes Not Linked To Multiple Myeloma Risk

According to new US study, even for decades, women who’ve used hair dyes do not seem to have inclined risk of multiple myeloma, a cancer in which malignant or cancerous plasma cells accumulate in bone marrow.

In recent years, some studies have tied use of hair dyes, particularly older formulations used before 1980s, to an increased risk of developing certain caners including leukemia and lymphoma. It is believed that hair dyes that are used before 1980 contain potentially cancerous substances.

A few risk factors for multiple myeloma have been recognized, such as African background and older aged adults. However, certain studies have suggested cosmetologist and hairdressers may also have higher than normal risk, which raises the possibility that chemical exposures at work are also involved in development of cancer.

In new study of US National Cancer Institute among 175 women with cancer and 679 without cancer, the researchers found no link or evidence that hair dye use as a major factor for cancer risk.

Overall, women who’d ever used hair dyes were no more susceptible to develop multiple myeloma that those who’d never colored their hair.

Even there was no increased risk among women who’d started using the product before 1980 or those who used them for 28 years or more.

 In addition, the study found no evidence that permanent dyes carried a different risk from semi-permanent versions.
