Regarding the hair shock, to be honest, I didn't really notice anything out of the ordinary. In retrospect, maybe I was indeed losing quite a bit more hair than usual for the first 2 months or so. So I would say that it wasn't really that noticeable. Some people have it, some don't.
By 5 months, the HT was great. I adopted a purely no shampoo routine immediately after the HT, just to try out some things I read online. In fairness, the routine worked amazingly until the 6th or 7th month. By then, my scalp had turned itchy, and hair started falling after light scratching, often with white bulbs at the ends. Small tiny yellow crystals similar to blackheads started to form also. This was probably caused by too much oil or sebum. After maybe 2 weeks of itching agony and some more annoying occasional hair fall, I decided that the routine just didn't work well with me, and I started minoxidil and 1% nizoral on a daily basis. If you ever had any qualms about using sodium lauryl sulfate shampoos, my experience tells me that it has no significant effect on hair other than to make some hairs a little crinkly. You can use whatever you want on your hair. I've since given up on all organic, SLS-free shampoos and similar all-natural programs. Nizoral everyday works for me, so I'm sticking with that. So to answer your question, I started using everything after my operation, when circumstances forced me to take some action.
My shedding with minoxidil was actually the scary part of the entire ordeal. By carefully counting hairs on my hands after shampooing and inspecting the drain after each shower, I estimate that I lost NO LESS than 4,500 strands of hair over a 2 week period. You can imagine how frustrating and worrisome this felt after having seen significant improvement with the transplant.
This happened probably less than 2-3 weeks into starting minox. The shedding lost some steam after that, but I was easily losing at least 100 strands (40-50+ on the hands, probably the same number in the drain) each day. I persisted in using minoxidil on a daily basis, and thankfully, everything came back after 2-3 months. I have always used it once a day, even if there are studies showing that using it twice a day yields better results. Twice a day is unmanageable and inconvenient on my end, not to mention diminishing returns, higher total cost of money, time, attention, etc.
I wouldn't say that the transplanted hairs are falling out permanently, if that's what you mean. They probably grow and fallout in the same manner the normal hairs do, as it's a constant cycle. Touching my scalp right now, I can still feel a lot of "sharpies" of various lengths - hairs that are below a certain length, standing up, and regrowing after having fallen off. As to whether those are the transplanted hairs or not, there's no way to tell. Transplanted hairs are there to stay for life. If after your first HT, you lose even more coverage and have a strong donor area, then by all means, do it a second time. Bottom line is that once you go for an HT from a qualified surgeon, you're definitely going to see results.
