What's happened
A Consumer Reports study of 21 at-home hair dyes and two chalk products finds dichloromethane, a probable human carcinogen, in every item tested. VOCs pose short-term risks like headaches and eye irritation, while long-term exposure raises concerns about DNA damage and hormone disruption. Brands including L’Oréal Paris and Revlon say their products are safe.
What's behind the headline?
Contextual Read
- This report consolidates lab findings with expert commentary to show potential consumer risk.
- The piece highlights a single chemical across all products, which elevates concern about ongoing home use.
Implications
- If home dye use continues at current levels, exposure risk could increase for frequent users.
- Regulatory gaps persist around VOC limits and dichloromethane exemptions in cosmetics.
Forecast
- Expect calls for stricter labeling and possible reformulations as brands respond to safety scrutiny.
How we got here
The CR investigation tested 21 boxed hair dyes and two chalk products sold nationwide, seeking phthalates, heavy metals, and VOCs. Elevated VOCs and a ubiquitous presence of dichloromethane emerged, prompting safety concerns even as regulators permit limited use with warnings.
Our analysis
New York Post reports on CR findings, with statements from ORiene Shin (Consumer Reports) and Ashita Kapoor (CR). Revlon and L’Oréal Paris provided comments. Additional context from the lab tests and dichloromethane’s regulatory status is included from CR’s release.
