Hair Loss - Vitamins, Diet and Supplements
Before I start on any allopathic remedies for baldness, Hair Revital X I have to explain the current thinking in science behind the causes of losing hair so that the mechanism and effectiveness of the drugs are easily understood.Men convert excess testosterone into a more potent form called DHT by the enzyme 5a reductase. The DHT is highly active on the hair follicle receptors, readily latching to them and restricting blood flow to the hair. This causes the hair to become thin and miniturized creating the "peach fuzz" look. There is apparently a greater quantity of this enzyme in the scalp of men who are susceptible to male pattern baldness.Women, however, have excess of the enzyme aromatase which converts their testosterone into a form of active estrogen called estradiol. The theory is that after women hit menopause, their levels of natural estrogen lowers letting the testosterone be converted into DHT which makes them more susceptible to losing hair post menopausal. However, that doesn't explain why post andropausal men lose hair when they become older and their testosterone levels die down.
