As the beauty and cosmetic industry evolves, many new skincare, haircare and hair styling products continue to flood the market. However, the safety of some of these products has come under scrutiny, in view of their potential health implications.
A study conducted by National Institutes of Health (NIH) and published in International Journal of Cancer in 2019 had revealed a concerning association between the use of permanent hair dyes and chemical hair straighteners and an increased risk of breast cancer.
The study found that women who used hair straighteners at least every five to eight weeks were about 30 per cent more likely to develop breast cancer. It also found that using permanent hair dye caused a 9 per cent increased risk of developing breast cancer compared to non-users.
As more people embrace these products, it becomes essential to know their potential impact on the body. Dr Pritam Kataria, Consultant, Medical Oncology, Sir HN Reliance Foundation Hospital, explains how some hair products can increase breast cancer risk.
1. Hair products contain Endocrine-Disrupting Compounds (EDC) and carcinogens potentially relevant to breast cancer among women. EDC is a substance that interferes with the body`s hormonal system and can mimic or block hormones and produce cancers. Carcinogens cause cancer by damaging DNA or disrupting normal cell processes in the body.
2. Resorcinol, used in hair dyes, can affect the proper functioning of hormones and trigger allergic reactions.
3. Formaldehyde, used in high concentrations in certain keratin hair straighteners, is a known human carcinogen.
However, he clarifies, “It’s important to note that the factors mentioned above do not definitively mean that these hair products cause breast cancer.”
Many other factors can contribute to breast cancer development, including environment, lifestyle and family history.
