In all honesty, I have a friend that is a nurse in the ICU for Covid. He refrains from visiting barbershops and spas. He says the cleansers they use in hospitals are much more expensive and effective, All surfaces in spas are not cleaned after each visit. Also, it is not possible to clean blankets and sheets without washing. I know that they are not replaced in the spa after each use. I have seen them merely wipe up junk from the sheet. But everyone has their own risk tolerance.
