From what I have learned, a superlather is a combination of shaving cream, shaving soap, and a few drops of glycerine. This got me thinking: is the shaving cream necessary? The reason why I am asking myself this question is that a superlather is basically double the amount of soap/cream and glycerine. So, would not loading the brush with twice the amount of soap we normally use produce the same effect?
To be honest, I have not felt any advantage of a superlather. I am not saying that those who use superlather are wrong. Far from it. It could well be that I have not seen a difference because Arko soap, Arko cream, Tabac soap, Martin de Candre, Body Shop cream, Palmolive classic cream, and Williams cream can perform well on their own. And the fact that I like thick lather is kind of a similar texture to a superlather.
