I was extremely anxious even though all my friends, who are EXTREMELY cautious, had done it. As you know, Florida has lifted all restrictions. That said there isn't a salon in our town that is stupid enough to have dispensed with masks. As my hairdresser said when I asked her if they were still following the original protocol, "Of course. Do you think we're that stupid; that we want to get sick?"
Ask around and make sure you are comfortable with the measures they are taking.
For me, my salon has a souped up ventilation system, my hairdresser uses the Shahag method (dry cuts), they won't do shampoos, you sit in the car until it's your time for the chair, and everyone is required to wear masks. I was in and out in 15 minutes. Brought nothing with me other than my car keys and exact cash to cover cost plus tip. She also made an appointment time for when they are the slowest (which happened to be 4:15 pm). There was only 1 other customer in the salon. It was scary, but I had to do it. My hair grows super fast (1 inch a month) and it was about 6 inches past my shoulders. The weight of it was giving me headaches, and it also hurt to put it up.
A friend of mine in the next county over uses a stylist who is on her own and only allows one customer in at a time and totally sanitizes between clients.
My neighbor went to a big salon here and everyone wore masks (this was back in May I believe). She got a call from the salon a couple of days after her visit. 2 of the stylists had tested positive. As it turned out over 100 people had been in the salon at the time (over the course of 2 days) and were potentially exposed. Not a single one of them got the virus, including the co-workers because they all wore masks. Turns out the 2 girls were likely infected at a bar.
Call ahead, be comfortable with the protocols, go in with damp hair, tell them you want a 15 minute cut & no blow dry, drop the cash on the desk on your way out the door and run like hell.
