Had a friend over who is hiv+ he cut himself and i touched his blood helping him, my hair also got into the blood. i washed my hands and hair shortly after. i do have some cuts and cracks on my hands. am i at risk for getting hiv?

Only is the skin barrier broken then infection may occur provided your friend has not been treated and his HIV virus load is high. In general, HIV transmission with this type of contact is probably less than 5/1,000 (0.5%). If the cuts and cracks are not open then your risk is extremely low. If you have doubt, do a rapid test after 6 weeks of exposure or earlier if you experience viral symptoms.

The type of activity mentioned is highly unlikely to result in HIV transmission. Cdc.gov is a reliable site in learning more about HIV transmission.
