As far as surgical hair transplantation is concerned, I think the limitation of blood flow and trauma, even if minimal, will always apply, so more sessions will have to be done if you want densities similar or equal to the natural one. I thought that with the use of robots instead of human hands a lot could have been solved, but apparently as far as hair transplantation is concerned, robots give a lower result than the surgeon for now. I too think it's better to get your hair back now rather than at an older age when the priorities are different, in fact we often speak "only" of an aesthetic problem, as if good sociability and high self-esteem count for nothing for human beings. My superior in the military always said that human beings only need three things: food, sleep, poop. I would also add another two which are leisure and sociality which also includes sexuality, without these a normal person lives badly and ends up going crazy. Not to mention that being forced to not be able to open up to the fullest, not to have the look you want is a limitation to the individual's self-determination and makes the person feel old before their time. Not to mention when this pathology arises at a young age such as adolescence, the boy will end up feeling finished and out of place, and let's be honest, it's not that his other peers are kind and mature with him, he will always end up being the one targeted for some joke, he will always have to be mature and not take it out on something that ultimately ruined his life and denied him a healthy relationship with the opposite sex. I find it really hateful and petty to call it only an aesthetic problem when a person's appearance is important (let's not say otherwise) and that this affects a person's character and future relationships.
