Since 18 March, government measures to combat coronavirus spread provide for the closure of all businesses, except for the so-called essential businesses. These are businesses such as food stores (including pet food stores), pharmacies, newsagents, fuel suppliers and hairdressers. Hairdressers were only allowed to receive one customer at a time and by appointment.
In view of the profession of hairdresser and the proximity involved, this last exception has been abolished. As of 24 March, all hairdressers, like other non-essential businesses and shops, must close down completely. You will therefore have to wait until the end of the coronavirus measures to have your hair cut by a professional.
