It's a legitimate question; if one of these companies comes out with a very strong maintenance protocol that is effectively a cure for those who have yet to progress through the NWs, how will that affect the companies pursuing regrowth? It will mean the market for a regrowth protocol becomes significantly smaller, and maybe not worth the investment.
So true. If a solid maintenance product comes out in the next 5 years, companies working on regrowth formulas essentially only have the current generation of high end Norwood's to market towards .. granted on a worldwide scale, the numbers are still huge, but percentage wise, of those who would actively pursue spending thousands on the hypothetical treatment, would it be even worth investing? It's almost going to be a race between maintenance formulas and regrowth formulas coming to the market in that sense ... and logically looking at the big picture, a solid maintenance product is where the money will be.
