I’m a former pt of bisangas and this seems like sound advice. I would like to add it seems like everyone has an opinion and is telling you to not try bht and don’t have any surgery again ever etc, but the truth is, bht is actually a last resort option for patients such as yourself who have no other option. It looks like you already have some hair on top that can be made into a hairline. If you do have donor region DUPA, body hair would be resistant to that, at least theoretically. You said you already have had bht, what was the growth like on that? You obviously won’t get full coverage so that’s where smp comes in but something may be able to be done with your hairline.
