Minoxidil is a drug that was developed for one particular medical use, and that was as a tablet to lower blood pressure by relaxing the blood vessels.
However, a different version of minoxidil was developed for hair loss and is applied directly to the areas affected in the form of a solution. It does not have any direct affect on the patient’s hormones which are responsible for androgenetic alopecia (or male pattern baldness).
It is not clear exactly how minoxidil works, but it may be that improved blood flow to hair follicles has a part to play in its effect.
Finasteride was originally developed for the treatment of enlarged prostates in men. This treatment is taken in tablet form and has a specific effect on an enzyme called 5 alpha-reductase which can produce high levels of DHT causing subsequent hair loss.
There are two main types of this enzyme. One is found in the oil glands of the skin and the other is found in the hair follicles, as well as in the tissues of the prostate gland. Men who have high levels of these enzymes, and particularly those in the hair follicles, are likely to develop baldness, as well as being more prone to enlargement of the prostate gland.
It was found that some men who were taking the drug for prostate problems experienced hair re-growth and the drug was then investigated specifically to discover whether it could treat baldness.
