I think the biggest concern regarding HM, after the issue of whether it will actually work or not, is the price tag it will have. I know it is very early to be talking about the cost, but I would imagine that the first company that does bring the procedure to market could not charge too much more than hair transplant's cost. Having a good product is only part of the equation of making money, the other part is actually selling it. Relatedly, I would not be surprised if the price of hair transplant's drop once HM is released.
