My SO and I are lucky, we got our hairstylist recommendation from my sibling. As of now, she is the only stylist in her studio. She takes people only by appointment and only has one client/family inside at a time. Before vaccinations were available, she wore a KN95. After her vaccination, she downgraded to a cloth mask. I personally still wear an N95 that I unstrap and hold to my face when she is cutting my hair. My SO wears a KF94.

Before that, I went to a barbershop. They were wearing masks but many times it fell below the nose. There was really no enforcement on other customers (but most did wear a mask). I haven't been there since summer 2020, so don't know what is happening now.
