10 days after hair transplant removing scabs, loss of grafts?

Anything is possible.  It probably is not likely but if you are concerned it is best to contact your doctor since there is no way to tell on the Internet.

It is unlikely after 10 days post op that you are disrupting the grafts. The most likely scenario is that what you are seeing attached to the scab is the hair shaft that would be shed anyway. If you have further questions you may want to contact your doctor.

At 10 days post op the grafts are fully secure in your scalp. So any scabs and hairs you remove now is just shedding of the grafts which is perfectly normal.
