Dear forum members,
We have performed BHT and facial hair test sessions and I have posted my findings before this time too.
In our experience, the transplanted body hair grows but does not take on any characteristics of the scalp hair.
In certain individuals, it may grow longer than in its original location, but that has nothing to do with it adopting any characteristics of the scalp hair.
As for some people making it sound as if BHT is useless, I think part of the reason stems from the irresponsible way in which results on an anecdotal single patient were extrapolated to make it sound as if the transplanted body hair will take on the scalp hair characteristics.
Another reason is, that as time passes, the technical gap between clinics that can successfully perform BHTs and those that can not, keeps increasing. Those that enter the field without proper training, then, blame their lack on the body hair.
Properly transplanted body hair and facial hair grows and retains their original characteristics (including their growth cycles). It is possible to use these hair in appropriate manner even though they do not grow just like the scalp hair.
However, people with fine calibre body hair are not going to get thicker or longer hair merely because they have been transplanted to the scalp.
We routinely offer test BHT and facial hair sessions (at no charge) to all patients undergoing a strip FUHT session or scalp FUSE session.
Body hair and facial hair are useful additional hair that can be used to boost the donor hair supply. When starting the first HT of the patient, the doctor and the patient should take it upon themselves to formulate a plan on what will need to be done, when, and if, hairloss keeps progressing up the norwood scale.
