Head & Shoulders

“I like this bare line because it doesn't have the tholinone preservatives like the classic clean.”

“Um, it's a zinc pythonone shampoo. I hope they don't discontinue this.”

“Other option is selenium sulfide, which can perform in some cases for some people better than zinc pythone.”

“So, if you've got dandruff and you've tried Head and Shoulders and you're not getting anywhere with it, try their selenium sulfide containing shampoos or try Cels and Blue, their competitor.”
