2 weeks post-op. Would it be safe to start using Minoxidil again?

I would advice my patients to start finasterid from the third week after a hair transplant  . But note that each doctor may have their own routine for post op care. Better to contact your surgeon for   recommendations . All the best

I would recommend waiting for a month after your transplant surgery before using Monoxodil, as it may dry out the transplanted area. You are fine to continue to use Propecia at this point. Other things that can help are proper hair care products. Gentle shampoos and conditioners or products related to hair loss such as Revivogen or Nioxin.
