NJ bill would ban dangerous chemicals in hair products

NEW JERSEY (WABC) -- A new study is raising concerns about the safety of hair extensions.

Researchers tested dozens of popular products and found 95% contained potentially harmful chemicals, some at levels that exceed European safety standards.

Researchers say the findings highlight potential health risks in a fast-growing, lightly regulated industry.

The wig and extensions market is expected to surpass $14 Billion by 2028.

As the industry grows, so do concerns about health impacts.

"They just put women's health at risk, especially black women who are one of the largest consumers of these products," Dr. Elissia Franklin of the Silent Spring Institute.

A new report by Silent Spring Institute was released on Wednesday that more than 90 percent of hair extensions tested contained hazardous substances that were linked to cancer, hormone disruption, developmental problems and effects on the immune system.

Those chemicals included flame retardants, phthalates, pesticides and organotins.

"The chemicals that we found in particular are associated with outcomes like breast cancer, which we know black women have the lowest survival rate compared to other groups of women," Dr. Franklin said.

New Jersey State lawmakers teresa Ruiz and Renee Burgess, are shedding light on the issue with Senate bill 4477.

The bill would make it illegal to put harmful chemicals in synthetic hair products made, sold or distributed in New Jersey.

"I feel as though it's a disservice that these warnings are not placed on certain products such as hair," Burgess said.

At Roots Rocks salon in West Orange, business owner and hair stylist Shivonne Desir has concerns.

"Braiding is a big part of the business. They are places that they can go to get alternative hair in the industry; however, it's not broadcast enough. So we have to find a way where stylists are able to know that information, get that information so that they can provide the same service without cutting their income," she said.

Hair enthusiasts hope the study leads to positive change.

"I love that we're getting to a place where we have transparency," one customer said.
