If no mention is made as to who, which lab, which agency made the study, beware, for it may be a lab hired by the firm pushing the product, i.e., the studies may have been done according to the specifications given by the manufacturer, the results of which will be skewed in favor of the product, of course.
Even legitimate medical studies have to hold their methodology accountable to the research community. So why shouldn't the makers of these hair loss treatment products?
Many of them try to support their evidence with "research" from foreign universities. Why is it that all these studies have to be done in Europe or Asia or South America? What have they got against performing the study in the United States? The answer is -it is more difficult to verify or scrutinize the study with a university in Albania, then it is with the University of Michigan. Anyone here speak Albanian?
Hair loss due to nutritional deficiency
Oh how they love to throw out such nutrititional terms as "minerals", "amino acids", "Vitamin B6", "Zinc", and so forth to make their product sound legitimate. And it is true that a nutritionally deficient diet will cause hair loss and will also cause a change of color, usually to orange or rust color.
However, what the promoters of scam products fail to mention is that in order for you to suffer hair loss due to diet deficiency, you would need to be practically starving for a period of time, and we mean to the extreme.
Even hair loss amongst persons suffering from anorexia is an unusual symptom. The fact of the matter is the western diet is quite sufficient to provide all the nutrients necessary for hair growth. This is contrary to what the promoters claim about the "insufficient western diet." It's simply not true. The western diet doesn't have anything to do with your hair loss.
If a shampoo type product promises to promote new hair growth by unclogging pores, you'll be better off if to keep the credit card in your wallet or purse.
Stimulates blood circulation
Well, isn't it an amazing coincidence that now, all of a sudden, their product, and some new ones, claim their special hair loss treatment product "blocks DHT" from damaging hair follicles. What they have so sleekly done is taken legitimate research and applied it to their own product.
While research is being done on other legitimate DHT blockers, finasteride and dutasteride are the ONLY DHT blocking products available to the general public that actually work. If you see a web-site offering a DHT blocking treatment for sale straight to the consumer, that is not dutasteride or finasteride, you better put your skeptic glasses on and hit the back button on your browser!
