I know 2 people in their 60’s who had hair transplants 2 decades ago for Norwood 1-3. Everything else now is bald apart from the horseshoe but the transplanted hair remains exactly the same. Scalp tension theory is bullshit and carries no scientific weight - all of it is people trying to apply logic in a field they don’t understand because they’re not scientists.
Do you really think the likes of Tsuji would be doing what they’re doing on a whim with the potential for it to not work because of ‘scalp tension’ .
