I hear this complaint a lot on the various forum and groups to which I belong, that their hard water makes lathering difficult. WHen I lived in Indiana and had a water softener soaps just performed like champons. Now I live in suburban Houston and my water is rock hard. Some of my soaps are impervious to the minerals. I'd like to hear if others share the experience and what soaps work for them. My latest expirament has been to take my worst performers and lather them by soaking my brush in a mug of warm distilled water. Wow, what a difference! This is a very inexpensive solution to boost your poor performers.
Ah, che bel vivere, che bel piacere per un barbiere di qualita.
