Some stages were transformed into hairdressing salons while others became yoga studios for the day in a protest action called Hair Salon Theatre, the brainchild of the well-known Dutch actor and cabaret artist Diederik Ebbinge.
Theatre operators are protesting the inconsistency of a law that allows people to go shopping but not to visit museums, permits hairdressers to receive customers but which forces theatres to remain closed.
The hard lockdown in the Netherlands may have ended on Saturday but cultural institutions and restaurants have been ordered to remain closed.
In one particularly unusual case, the Van Gogh Museum in Amsterdam was transformed into a hair and beauty salon where customers could have their nails filed while enjoying priceless masterpieces by Vincent van Gogh.
"We want to emphasise that it is safe to visit the museum," museum director Emilie Gordenker said.
In one Amsterdam theatre, the 200 hair-dressing appointments were sold out within minutes, perhaps as popular cabaret artists were due to perform while customers got their hair done.
At Amsterdam's famous Concertgebouw concert hall, visitors were even able to get their hair cut while listening to a full orchestra performing just for them.
Mayors across the country expressed their sympathy for the protests but nevertheless intervened.
Some theatres were forced to continue their action outdoors while others received an official warning.
