Thanks for the photos. It is normal for the hair and scabs to "fall out" after a week. By then the follicle is generally integrated into the scalp. Thus, what you are seeing is most likely not the follicle.
They don't look like scabs. They look like dried out grafts. I generally say you can lose 2 to 3 grafts for every 1000 grafts. So for a 4000 graft surgery I guess 8 to 12 graft is normal.
Grafts fall out after 9 days
After transplant, the scabs are
formed after about one week. And the hair start shedding after 2-3 weeks,
sometimes earlier and sometimes later. So there is nothing to feel nervous
How many grafts can fall out after a hair transplant
Within the first 3 weeks, all of the grafts may fall out and that can be normal provided that you are careful with your washing technique. Don't worry.
Scabs after hair transplant
mostly hair shafts that separate from the. Follicle and fall off along with the scabs is normal. The follicles remain under the skin and will start to grow in after. Few months. If the follicles are attached then you have lost the graft and that could be from poor placement.
