This makes sense really! Some use powder before waxing or using an electric razor in order to raise the hair. I suppose, when using a straight razor, the powder acts as a kind of lubricant for the razor to glide over while protecting the skin from razor burn......
It all sounds logical, but I'm still too chicken to give it a go!! But, the "woman found dead in tub; drowned shaving" headline might show up in my local paper if my coordination doesn't improve!!! LOL
