2/$8 VO5 hair treatment

Condition: bottle is unopened and unused Info: VO5/V05 hot oil conditioning hair treatment. One 0.5 fl oz tube. Story: This was given to me, but I never tried it. I've held onto it, but it's safe to say I'm not going to get around to this. I can't even figure out the name. I thought it was V05, but google showed me VO5, and now I am so confused...
