Science does not understand well animal and human hair growth cycle interactions with its biochemical metabolism yet. Recent research may have unintentionally discovered another piece of the puzzle that is hair graying and male pattern baldness but it will be decades until laboratories develop a practical and effective product. For now, we can only draw practical conclusions from these research studies, one of which is that vitamins for hair growth by themselves aren’t enough to prevent male pattern baldness (MPB).
The scientific community has always thought high cholesterol levels in blood to be linked to increased risk of cardiovascular disease and coronary heart disease. Food and nutraceutical community regarded sterol and stanol supplementation as a solution for lowering LDL (or bad cholesterol) levels without the harmful side-effects of statins. Unfortunately cholesterol lowering products have become so lucrative that this area of knowledge is full of fallacies. Any person that has problems with her cholesterol and want to lower LDL levels effectively must understand what has been really proven in research and what is marketing before starting with a plant sterols supplement.
