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

It is best to ask your surgeon about post operative care as each doctor has their unique regimen.   In general, there should be no issue in resuming minoxidil.

Depending on the doctor they usually would recommend you resume Minoxidil anywhere from 2-4 weeks after your transplant. You should ask your doctor when they think is best, since only they know all the specifics about your particular case.

I recommend my patients to continue using finasteride and to not stop for the procedure, and give the OK to use minoxidil at the 2 week point. If you have any questions, you should double check with the surgeon who performed your procedure.

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. 

At 2 weeks post op, you can use minoxidil if all of the crusts are off. Minoxidil will have no effect on the new transplanted hairs
