This is probably not the answer that you want to hear, but after 9 liver flushes, I noticed no reduction in the gray hairs that had popped out. If anything, I noticed a few more that popped out. Perhaps, someone with more Liver Flushes under their belt may have better news for you. In the mean time, I have decided to live with the problem as it is not noticeable. In my case, we are only talking about a few single gray hairs. Now, to avoid a salt and pepper look(that is how graying progresses), I may have to resort to some natural hair coloring techniques, so if it comes down to that, I plan on testing the following natural recipes for hair coloring.
