i have been making my own lather the traditional way,with a brush and cream or soap for months. so i forgot how bad the crap that comes out of the pressurized cans is. with traditional the longer i leave it on the more it hydrates and softens my hairs, but the cans do the opposite. i'm sure there harmful ingredients in the cans too,but i'm not going to get into that. i just prefer a comfortable smooth shave with the traditional methods.
