"Dandruff Shampoo Could Mess Up Waterways"

"Every time you wash your hair, a lot of shampoo goes down the drain. And if you're bothered by tiny white flakes, odds are you use a shampoo that deals with dandruff."

"Such medicinal shampoos often include a fungicide. A fair amount of fungicide thus ends up at the local wastewater treatment plant. Those industrial facilities remove a lot of stinky stuff. But they mostly fail to grab the drugs in soaps, shampoos, toothpastes, perfumes, sunscreen and other skincare products that our daily habits add to wastewater.

Now a study has detected fungicides from anti-dandruff shampoos in the water."
