their boyfriends, brothers or male friends.The campaign is aimed at the growing number of teenage girls in London who, the Met says, are being persuaded to store weapons for male gang members.
Police will be targeting girls aged between 15 and 19.
People caught hiding a gun for someone else can expect to receive a five-year prison sentence.
Despite this, police say, an increasing number of women are concealing firearms for partners and male friends involved in gangs.
The number of women charged with firearms offences in London has increased six-fold in the past year - 12 women have been charged since January, with over half of them teenagers.
Gun possession makes up the vast majority of these crimes, prompting the Met to launch the campaign aimed specifically at black teenage girls.
Officers will visit nail salons and hairdressers with the message that women carrying or storing firearms will face the same sentences as men.
Police in Manchester and Birmingham say they are also dealing with these sorts of cases, but not in enough numbers to warrant a specific campaign.
