one of the best doses foams, however, relatively expensive.

I use the foam Nivea for years very much. Despite occasional testing of other brands so far I could not find alltagstauglicheres product.
The foam is very strong and easy to dose. The can holds relatively long. I "dilute" it. Like with water next to the skin It makes the hair after a relatively short exposure time nicely cut soft and does not clog the space between the blades of my 6 favorite razor.

As disturbing I find the relatively high price. The fragrance could turn out discreet for my taste.
