BHT leg hair transplant - will it grow longer than the rest of my leg hair? (Photo)

Hello, I lost most of my hair on the outer shins, and I'm having difficulties finding surgeons experienced with this (rare) procedure. My biggest concerns are, if scalp hair is used, how likely is it that it will keep growing longer than the rest of the leg hair, and also in regards to scarring, how likely is it and what to pay attention to when transplanting into the shin area? And lastly, since I lost my shin hair, can the scalp/body hair not fall out just the same? Thank you very much for any insights.
