No, You Don’t Need To ‘Detox’ Your Showerhead

The “shower sickness” to which Goop refers is a real disease caused by nontuberculous mycobacteria, or NTM. Between 12,000 and 18,000 people get NTM infections each year in the U.S., from mild to severe. The infection can become chronic, and treatment often includes multiple medications taken for a year or more.
