You need to update with latest pics and you need to wait for 12 whole months, in February I think it was seven months so it should be in July. I think you will get much better growth in July.
You also mentioned that technicians are from Odisha, that is Dr Pradeep's home state, and the technicians are probably from his village, thus since they are from his village seasoned technicians stick with the clinic rather than get training and get a job elsewhere.
I also had a transplant in India where the doctor himself did the extractions but he did a very poor job. Eugenix's technicians are far superior to most doctors in India. You also mentioned that you are shedding roughly 500 hairs, hair shedding is normal and healthy hair shed, that is their cycle.
Again post recent pictures and wait for 12 months. You also have enough donor hair and donor management from Eugenix looks good. So in case the results are sub optimal then you have enough donor for a repair.
