I had an accident nearly two years before and had a scar on my upper left side of moustache area where there is no hair growing on that scar. hair Transplantation surgeon cannot promise 100 % hair growth on scar area as it is all depends on my scar and how that responds. I am not sure whether it is worthy to take risk or not. Please suggest. Also, That would be good to know what could be the consequences if the hair won’t grow on planted scare area in after hair Transplantation . Is that scar gets worst.
