I found about 20 grafts and blood on my pillow the first night after my transplant. Should I be worried? (Photo)

In general, you never want to lose a single graft.  In my experience losing 20 grafts is more than I typically have seen.  However, if you had a relative large case like 2000-3000 for example, 20 grafts should have minimal impact unless they were all in one area close to one another or along one side of the hairline for example.

Don't panic. As long as no further grafts are found, there should be minimal impact on your results. However, make sure you discuss this with your surgeon, and if you require an additional procedure, it is reasonable to expect a few complimentary grafts. Also make sure you are following your post-operative care instructions carefully.
