(TELEGRAPH) — One million people may be using deodorant needlessly, a study has suggested, as they have a gene that means they do not produce body odour.

Researchers have found that two per cent of the population have a genetic variant that means they do not suffer from under arm body odour yet more three quarters of them continue to use scents.

The ‘cultural norm’ in Britain is to use deodorant every day whether body odour is a problem or not, the researchers said. Where as elsewhere in the world most people with the genetic variant are aware that they do not smell and do not use deodorant, they said.
