Selsun Blue Chemicals Can Cause Irritation and Hair Loss, Says Class Action Lawsuit

Toxic chemicals in the anti-dandruff shampoo Selsun Blue can actually aggravate scalp problems and even lead to hair loss, a class action lawsuit claims.

Lead plaintiff Emily Lewis accuses the shampoo maker, Sanofi-Aventis, of failing to inform consumers about toxic ingredients like selenium sulfide used in the product.

Lewis says she purchased Selsun Blue in 2020 based on marketing that it could help eliminate her dandruff and dry scalp. However, after using the product twice a week as directed, she claims her hair became brittle and began falling out. She also did not see an improvement in her dandruff.

In addition to selenium sulfide, the complaint contends that Selsun Blue products contain a preservative called DMDM Hydantoin. The plaintiff says that this ingredient can cause irritation and even release formaldehyde, which is another toxic chemical.

Further, Sanofi fails to disclose scalp irritation and hair loss as a potential side effect of using Selson Blue products, alleges the lawsuit. Lewis says that she and other consumers wouldn’t have purchased the product if they knew about the toxic ingredients.  Indeed, the complaint points to reviews on the online retailer Amazon complaining about the false advertising of Selsun Blue.

The class action lawsuit seeks to represent a nationwide class of consumers who purchased and used Selsun Blue products within the past three years, along with a subclass of Illinois residents.

This is not the first class action to be lodged over Selsun Blue. In December, a consumer filed a complaint in New York federal court claiming the manufacturer made false claims about the product being “natural.”
