I had my HT by Dr Hamayun Mehmond at Islamabad on 4 Nov 2011. 18 days post op, my transplanted hair are still in place and have not shed. Should I rub them with towel after bathing to make them fall or not? Moreover, I still have scabs on my scar and it pains when I touch the scar. Is that normal? Do i need to be worried abt it?
