Personally, I think u need to go to a crown expert and not worry too much about the technique or whether or not they do long hair fue. Crown restorations are much more difficult than hairlines but some of the best crown results I’ve seen are coming from doctor wong and Lorenzo. There are a few konior cases that have popped up here that are impressive as well.
I have a different outlook on the Long hair and bad hairstyle aspect of hts. Yes, the recovery sucks really bad. But by shaving your hair down you are helping the doctor match the hair angles as best as possible and a Temporary nuisance is worth long term results (imo).
