The short and sweet of it is that you can get a year's worth of shaves out of ONE disposable razor. Sounds unbelievable doesn't it? Now I haven't got a year to try this before I post, but I have already begun the test. Should be an interesting, and CHEAP, experiment.
The razor blades do not get dull from shaving your hair off; they are made of steel. The razor gets dull because it is left in the shower and stays wet/damp causing the steel to start rusting. The trick is to dry it off after each use and keep it in a dry area. A quick shot with your blow dryer should dry it nicely. I leave it up to you where you stash it.
Combine one razor for a whole year and a bottle of cheap hair conditioner to shave with and you can stay silky smooth for almost nothin'. My kind of deal!
Have a fabluous week.
