Hi Nick,
If your not already on it I would suggest minoxdil 5% to help prevent shock loss, which is just a short term set-back, the hair will regrow with the new hairs in 3 months.
Don't worry you are not losing the newly transplanted grafts when a scab falls off generally the hair shaft will also come away with the scab, as well as a small piece of skin tissue. Dont forget it's not the hair that is important, it is the follicular sheath that contains all the genetic material to start growing a new hair, that has now embeded itself under the skin, new hairs will begin to grow thru in 3 months..
the hard part is being patient...like watchn grass grow
