A believe a affordable price would be the costs of a hair transplant surgery plus the cost of the hair cloning technique, this one being a bit more expensive than the techniques we have today to remove the hair from the back of the head. In other words, a affordable price would be more expensive than the hair transplant techniques we have today, but not by much.
If I remember correctly, the price that Tsuji had given us was around 200-300k at launch. If a hair transplant is already seen as expensive and requires extensive financial planning for many ppl, a treatment much more expensive than that would be impossible for most ppl.
I am cheering for a cure, but I hope that the treatment becomes "affordable" and not just a cure for a small percentage of the population.
