I recently had to have a cold water shave when our hot water system went down for a couple of days. I used the Body Shop's Macca Root cream and shaved with a 120+ year old John Heiffor 6/8 full hollow razor (my current favourite). I applied the lather once, rinsed and applied again to ensure full hydration. The result was a damn fine shave. I would have used Proraso if the weather had been warmer but we're having a rainy spell here and it's a bit cooler than usual.

My conclusions: you can shave perfectly well with cold water in warm humid weather. I don't think it would be as enjoyable in winter, or what passes for winter in these parts.

I'd be interested to hear what other tropical climate shavers have to say.
