Scab and attached hair. Did I pull out the grafts?

Transplanted hair follicles are generally secure after the first week or two. If you are concerned you should contact your doctor.

Typically it is very difficult to damage a hair transplant after 2 weeks. The exception to this would be a sunburn, which needs to be avoided for 90 days. What you are probably experiencing is the new hair breaking off and attached to the scab. The follicle is typically under the skin being nourished etc... and will return 4 to 8 months later.

It is common for hairs to shed after a transplant and they may come out with some of the crusting.  Fortunately, At two weeks post surgery, it would be unusual to have the actual hair root (graft) come out with the crust - the hairs should be well engrafted by then,
