I'm glad you're satisfied with Dr. Khanna (may be he get better who knows), I feel like I needed to straighten out my remarks on him, first of all I never say that he was unfriendly, rather he is friendly, polite, eloquent and quite convincing, in short, he's a marketing genius. But my experience with him regarding hair transplant was very disappointing and way below expectation, to be honest, extremely regretful.
A few years ago, he implanted 1500 graft FUT (which was doubtful as it's very thin) on my receding hairline. He implanted the graft in a regular line pattern, like that of a barbie doll, which looks unnatural and extremely fake. I could only comb my hair in such a way that it look ridiculous and I dare not parted my hair sideways ever, I've been ridicule so many times. To be honest, if I could see the end result before hand I would have never opt for HT.
I truly don't know if he get better or not, may be he does. Anyway, concerning his skills, your HT result will speak for itself and I think its too soon to recommend or condemn or judge his skill at the moment. But one thing I can say with certainty is that he does charge higher than most HT surgeon in India.
