There are many toiletries in Erika Kohut’s bathroom. In the screencap above, a can of Schwarzkopf Taft hairspray can be seen on the mirror shelf. This product is still on the market, with a different packaging.
A tube of Meridol toothpaste is on the mirror shelf, while a bottle of mouthwash from the same brand is on the shelf on the top right. There are Veet shaving cream and Lux bubble bath (in both cases, old packaging) by the tub.
