Can Shampoos and Conditioners Lead To Hair Loss?

A recent class-action lawsuit claims that Johnson & Johnson’s OGX haircare line of shampoos and conditioners leads to hair loss. The claim? An ingredient called DMDM hydantoin is behind hair loss.


DMDM hydantoin is a common preservative found in skincare and haircare products like shampoos. They are usually found in small amounts in these products to prevent bacterial and fungal growth by releasing trace amounts of formaldehyde.


Prevention reached out to Dr. Rodney to find out if these claims are valid. Read on to learn about the product, if you should be worried, and what are your options.
