I ve undergone a hair transplant 9 months back and grew dense hairs, but since last 2 months I developed etching in scalp which results in loss of hairs including transplanted ones..almost 50% of my transplanted hairs have been lost..ive stopped using minoxidil..now I m using kertyol PSO but itching and hairfall continues although not as it was earlier..doctors don t believe that transplanted hairs fall..but I m damn sure they r falling..please suggest treatment
