You need to wait until 6 to 8 months to even start (not finish) judging results, in most cases. I don't know how this other guy is presuming to be able to evaluate your results at only 4 months. You need to chill and wait it out and not have some dude cussing over the internet and trashing your doctor make you worried - not yet. I have been told by my surgeons that 3 days is the sweet spot for grafts to be firmly in place, but other doctors reccomend 5 to 7. The reality is probably that most are firm by 3 days and afterwards only a small percentage might be susceptible to coming out by excessive friction, but I am not a doctor and don't know the backing studies that support this are or what these percentages may be. Thus, I don't think this is an issue in your case.
