I didn't dare to dig it deeply, it was really a big single one because the doctor did a lot of mini to archieve a good density just one sugury. it takes 4 to 5 days for me to make the whole scab off,just sometimes I use my nails to help it turn up since it stuck to my scalp too tightly and if I didn't do so,seems it won't get out by itself even after one month.fortunately most of the parts was ok,the scalp under it was pink,some hair fall with scab and some remain, sometimes there are obvious holes which are a little more red but became healed and flat after a few days.(are these kind of things fine and normal?)there was just one accident that once when i was trying to pull one of the scab off, the scab together with some hair are out,there suddenly appear some blood from the hole caused by the mini,not much,but just a little,which already scared me! that blood stopped and form a tiny new scab after 15 minutes,i just wonder whether I hurt the folicle underneath? he told me the blood supply on my original scar was quite good, anyway,maybe because it was not a bumpy one but rather a flat one. hope everything is right. hope you can answer my verbose questions doctor
