I have moved from a can of shave cream to a soap with a brush. I bought the soap almost 2 years ago now and although I don’t shave every day, the soap is lasting a ridiculously long time.
This will reduce your expenses and the amount of waste you produce. There really is no need for all those cans. The shave is great and I will never go back to cans of foam or gel.
The soap is from L’Occitane although you can look into many alternatives. Change the way you shave and be more conscious of what effects on the environment your habits have.
