If you are a bit anxious about Covid 19, maybe try somewhere else for now as the hygiene is a little lacking.
1) Given it’s fairly close contact, I asked the therapist to put a mask on as she wasn’t going to. She was going to thread as normal using her mouth to support the thread (er nooo) rather than neck as it’s more comfortable.
2) I didn’t see her wash her hands before threading.
3) I really doubt the brow comb (or scissors) is sterilised before or after as it was lying on the table.
