Oct 12 (Reuters) - The world's richest man, Elon Musk, has scented a new opportunity to capitalise on quirky products, launching a perfume called "Burnt Hair" that he said sold 10,000 bottles to earn a million dollars in just a few hours.

"With a name like mine, getting into the fragrance business was inevitable – why did I even fight it for so long!?" Musk asked on Twitter, where he now describes himself as a perfume salesman.
