The last time we were in Glasgow, we spotted hair straighteners in the bathroom at a major mall and thought, “What a good idea.” We promptly forgot about it until we spotted a news item about the machines in this week's Springwise newsletter. Here's the scoop. Straight Up is a machine that lets women use a ceramic hair straightener for a quick touch up on the go, and 90 seconds of use costs just one pound. The company which markets the machine is called Beautiful Vending, and the entrepreneurs behind the idea say they were inspired to invent it after hearing their female friends complain about the effects of Britain's humidity and constant drizzle to their hair.  So far there are 500 machines in the UK. Its such a good idea that we expect to see even more of them rolled out soon. Now there will never be an excuse for a bad hair day.
