Occupational disease prevention in barber shop?

It is normal to have cracks in your hands because you are exposed to water and various shampoos every day. It is recommended to soak your hands in warm water after work every night, and then apply vaseline or ordinary hand cream. There is not only all kinds of dust in the barber shop, but also broken hair residue. If you really have respiratory diseases, this is normal. It is recommended to eat more fungus and pears, both of which are lung-clearing.
