The only risks for HIV in adults are:
1) Having unprotected (no condom) penetrative anal or vaginal sex, OR
2) Sharing IV drug equipment with other IV drug users.
HIV never infects people because of minor cuts and scrapes that do not require EMERGENCY medical attention. HIV is not transmitted via blood outside of the body, on surfaces. A barber blade cut also isn't a risk.
You had zero risk for HIV.
