After 3 months your grafts are secure, the problem is you havent seen the final result of your transplant not until 12 months. For ever patient that has had a bad result it comes unfortunately to questioning if something was done wrong from their sight but for the most this is not the case.
So to answer your question if you dont have any skin conditions or other health issues that will cause hairloss, for your transplanted and native hair also, your transplanted hair after 3 months should be treated like native hairs.
