Q. Hi i’m a 34-year-old woman from Iran … I cut my hair by a hairdresser Male model by Clippers … The hairdresser used a comb on an electric clipper … Clippers metal surface was not in contact with my skin … Is it possible to transmit hepatitis B and C and HIV virus by assuming that the Clippers’ shoulder is not sterilized

A. HIV virus, hep c and b can be transmitted through blood-to-blood contact.  If there was blood on the clippers that contained the virus and you had any cuts or breaks in your scalp then virus could be transmitted.  From what you describe your blood did not come into any contact with blood from the clippers.
