gtz,
Yea this part of the process is the toughest in my own opinion. I was a nervous wreck, because didn't want to dislodge any of the grafts when attempting to rub away the scabs. What worked for is soaking my entire head about 10-15 minutes before washing my hair. This helps loosen the scabs. I also used vitamin e oil throughout the day, which seemed to help a lot. Hope these tips help a little...
