What Hair Restoration Products Need To Be Successful
You can find all kinds of products that claim to restore hair. There are creams and shampoos and conditioners and herbs and what not. Some of them work but most of them don’t. They are ineffective because they don’t attact the root of the problem. The condition that causes hair loss in most men is known as male pattern baldness. This is a situation in which DHT, which is a metabolite of the male hormone testosterone, builds up at the barrier between the blood supply and the follicle of the hair. This literally starves the hair growth unit to death and the hair shaft eventually falls out.

If you are looking at a hair restoration product you need to find one that treats this overabundance of DHT. Otherwise you are just wasting your money. There are two methods of attack which can be used when approaching the DHT problem. The first is to limit the production of DHT and the other is to inhibit the attack of the hair follicles by this hormonal element.
When limiting the production you want to find a product that controls the enzyme 5alpha-reductase. This enzyme transforms the male hormone testosterone into DHT. When the levels of 5aR are lowered that gives lower levels of DHT which in turn means there is less available to attack the hair follicles. There is a drug that has been approved by the US FDA which inhibits the production of this hormonal substance.
Finasteride was originally developed to treat male prostate problems but it was found that men in the study groups also saw new hair growth. Further studies indicated that DHT affects both hair loss and male urinary problems. The drug has now been approved as a hair loss treatment for men but women are not prescribed the drug due to the possibility of birth defects in male babies. If you are a man suffering from male pattern baldness then this is a great way to limit the effects of DHT.
