Nice work with the illuminating write up! Your frustration with the clinic is understandable, but try not to scrutinize everything before the result is complete. If you overthink it and are looking for an unsatisfying result before it's complete, you'll be primed for dissatisfaction even if the result is really great.
Temples are tricky to gauge early in the process - there's a very good chance they'll end up looking amazing. Asymmetrical shedding isn't an issue btw, everyone sheds differently and at different rates. Everyone hopes they will be the rare patient who doesn't shed at all, only to be disappointed 😂
I think there's a very good chance that the temple choices will make sense in the context of your final "after" photos. Hang in there and soon you'll get to experience what we all yearn for through hair transplantation - looking slightly more attractive for the rest of your life.
