The work done by Northwestern University Feinberg School of Medicine faculty members (and even some students) is regularly highlighted in newspapers, online media outlets and more. Below you’ll find links to articles and videos of Feinberg in the news.
The chemical PPD is found in about 80 to 90 percent of hair dyes in salons and consumer products for use at home, says study author Dr. Andrew Scheman , an associate professor of clinical dermatology at Northwestern University. Most so-called natural hair dyes on the market are really just gimmicks, according to Scheman. “They’re not natural at all,” he says. Like other hair dyes, he says, many brands that claim to be natural contain PPD or PTDS with a few extra botanical ingredients thrown in. Scheman emphasizes: “If somebody’s allergic to hair dye, they’re not going to be able to use the hair dye to which they’re allergic. Period.” Scheman also sees patients with significant hair dye reactions. “They can be terrible,” he says. “Patients can have totally eroded, inflamed and raw scalps and facial skin. Sometimes it’ll go down on the neck, or even spread to other parts of the body.” You can’t immediately assume hair dye is responsible for this type of reaction, Scheman says.
