Janine Marti trained as a hairdresser in Biel and then completed make-up artist school in Bern. Severin Marti studied women's hairdressing in Täuffelen and men's hairdressing in Biel and is a graduate of the make-up artist school in Winterthur.

Since August 2008, Janine and Severin Marti have owned their own business, Zweifach Frisöre und Visagisten, in Ipsach near Biel. Only the best is good enough for Zweifach's customers. That's why Janine and Severin have opted for products manufactured without animal testing and for the environmentally conscious working philosophy of Paul Mitchell. The two of them regularly attend workshops run by the haircare manufacturer for further training.
