In addition to the barbershop guidelines set by Illinois I have invested in the following precautionary measures:

1.  Surgically Clean Air (air filtration)

2.  Germicidal UV lights (used after hours)

3.  Barber capes (always laundered)

4.  Never a crowd (It's a 1-man shop)

5.  Re-certified on barbershop disinfection

6.  Contactless payment option
