The problem with Tsuji's approach is that the people that can afford his treatment are the same people who probably won't care to get it anyways.
Seriously most people who can drop 300k+ are probably in their 50's, have a wife and kids, and would rather invest the money instead so they can retire earlier.
That's not to say older rich people don't care about their hair, they most definitely do. But they don't care as desperately as us younger guys do.
It depends on what you mean fron younger guys.
If you are talking about NW1-NW4 young guys, the younger ones can get a hair transplant that typically "resolve" the problem.
On the otherhand, old guys (45+) typically have a advanced balding that cannot be resolved only with sirurgy.
I mean, probally old guys will need more hair clone than the younger ones.
Me for example. I'm afraid to become very bald in my 50's. Since I know it is very difficult to recover hair at this stage. Then I wish hair clone to be available soon just to know that will have a solution in the future to this scenario.
Plus, I think the biggest market will come from the older guys, by the same reasons I described: Typically they have a more advanced baldness stage which needs hair clone to complete recover.
@Edit: that considerations are logical to me, pointing hair clone will be very expensive.
If it is not and is pretty stable. Then the younger ones eventually will can choose hair clone directly instead of the hair transplant.
The most difficult to hair clone is all stage before the state that proves it can be applied to humans successfully. After it, I'm almost sure the time to it comes to market will be very small. Nowadays, new technologies comes to public too fast after its maturity.
