Hi,
I met the surgeon (Edward Ball) and his senior patient adviser (David Anderson) for my 6 month checkup a few weeks back and we all pretty much agreed it's because........well........"I'm a freak".
In all seriousness, I just think I'm at the lucky end of the scale when it comes to how quickly growth comes through, but in particular, and with reference to the normal HT graft cycle of shed, wait, and regrow, I petty much skipped the first two parts and went straight to regrow for a significant amount of the grafts (not all, but a lot). On top of the hair I already had, that gave the appearance of a full result very quickly, although it has definitely kicked on in the last two months.
This was me last weekend, very strong sunlight outside, so gives a great view of the result. Hair is now longer, so not in that "sticking up" phase when I posted last.
