I checked your profile, I think your case is different (NW 2) with a smaller area to cover so your doctor was able to put much more grafts in smaller areas.
In my case I was NW 4 at the time of the surgery ( early thirties) and the doctor was predicting that I will end up NW6 in 10-20 years, now I'm progressing to NW5, so putting the same number of the grafts you had in the same area that you filled would be a suicide as all of the donor hair will be exhausted.
I checked Rahal website and his results posted in forums but I was suspicious as he takes young patients in their early twenties with NW2 and uses half of their donor hair to give them a teenager hairline and even fill the temples which isn't recommended ,I was wondering if he informed them of the risks.I don't feel comfortable with doctors who do risky procedures.
I has my second HT surgery done 2 months ago ,all the grafts have fallen and still waiting to see some growth.
