Erratum to: Dermatol Ther (Heidelb) (2016) 6:69–75 DOI 10.1007/s13555-016-0093-x

In the original publication, in the Methods section, Scholl Fungal Nail Treatment is incorrectly attributed to Bayer Healthcare AG who is neither the manufacturer nor the market authorization holder. This should state Scholl Fungal Nail Treatment, Reckitt Benckiser Healthcare, UK.
