Competing Interests

The funder L'Oreal had no role whatsoever in data collection and analysis or preparation of the manuscript, but Albert Duranton and Lionel Breton (employees of L'Oreal) had some role to play in the study design and publication of the data. This does not alter the authors' adherence to all the PLoS ONE policies on sharing data and materials.
