Sharing razors or contact from hair clippers is not an issue because the blood is exposed to air, which inactivates HIV.
Sharing needles is a completely different scenario and refers to IV drug users sharing works...if you did not shoot up heroin at the barber shop from a used needle then you have no HIV concerns.
HIV is transmitted by:
Unprotected penetrative anal and vaginal sex
Sharing works with other IV drug abusers
Mother to infant.
I am not sure what is meant by environmental surfaces; why does CDC says that it does not recommend sharing razzors, and needles? Are they not environmental surfaces?
After you were advised it was a no risk situation, that's the end of it.
HIV is a SEXUALLY transmitted disease. HIV would only be transmitted at a barber shop if the barber inserted his penis inside you.
If you cannot shake this notion then consider seeing a psychologist about OCD.
I do not know what you are saying; I have never visited this forum. My question is about getting HIV from a hair cut bruising. Can you get it that way? What if it has infected blood?
