Oh no, what terrible timing. Is there a way the space can be used in some way to build your virtual brand while you wait this out? Ie building a buzz for the services like giving tutorials from the salon? To build up a fan base until you can open.
So much of life is online at the moment. My open studios for work have gone virtual, a friend gave a virtual open house to rent her flat since they didn't want visitors in their home, etc.
Best of luck.
