Can hair dyes and straighteners cause breast cancer? – Life News

Hair dyes and straighteners often contain endocrine chemicals that interfere with hormone function in the body. Ingredients like aromatic amines, parabans, and phthalates are commonly used in permanent hair dyes, while chemical straighteners often contain formaldehyde and other related compounds.

“These chemicals can damage DNA and lead to cancer. Formaldehyde, commonly used in straightening treatments, can be absorbed through the scalp, especially when heat is applied during styling,” said Dr. Monika Jani, gynecologist and obstetrician at Bhailal Amin General Hospital in Vadodara FinancialExpress.com.

These chemicals are absorbed through the skin during use and can build up in the body over time, contributing to hormonal imbalances that affect breast tissue growth. This can also lead to disruptions in estrogen levels.

“While occasional use of these products may not pose a risk, frequent and long-term use may increase the risk of developing breast cancer. Women who use chemical hair straighteners every 5-8 weeks are approximately 30% more likely to develop breast cancer. The darker shades of hair dyes contain a higher proportion of chemicals, the risk exists even with regular use,” said Dr. Jani.

She also said the frequency of product use needed to be minimized or switched to less toxic alternatives such as natural hair dyes. It is recommended to avoid heat treatments in combination with chemical straighteners as heat accelerates chemical absorption.

“Women with a family history of breast cancer may be more prone to developing these risks. You should take extra precautions by reducing your exposure to such products. Women are advised to weigh the benefits of hair dyes and straighteners against possible health risks. Choose safer products, reduce frequency of use and educate yourself about the product to minimize risks,” she said.
