You may have read the studies which indicate that the effectiveness and response someone has from minoxidil is determined by the amount of sulfotransferase enzyme activity that person has, which varies among people. The minoxidil sensitivity test which tests for sulfotransferase which was supposed to be released for the US, I don't think it has been legitimately released, I don't see it being sold from google or any major vendor/retailer. The HairMax laser comb has a 5 month money back guarantee, impressive before/after photos, and several clinical studies showing it's effectiveness. I've on finasteride right now, and only used minoxidil once last night but I'm wondering if I should use the laser instead. I wouldn't lose money, and wouldn't have to worry about not having sulfotransferase, and it if it did work it would be cheaper and easier in the long run. These minoxidil sulfotransferase studies also claim that minoxidil only works in about 33% of the population because of the varying sulfotransferase enzyme activity in individuals.
