A major population of current youth is suffering from the problem of hair loss and baldness. Frequent runs to several clinics seldom provide the relief. Quiet ignorant about its cause, the sufferer looses hair as well as the money.
Most common type of hair loss is the pattern baldness or andro-genetic alopecia. Andro- connotes to hormone and genetic signifies the inheritance. Collectively, the term says that the person has a genetic makeup for baldness which gets its physical manifestation due to hormones.
Like most of the other characters, baldness too have a particular gene which one inherits from their parents. Just the presence of gene is not sufficient for the physical appearance of the character. Next comes into play, the hormone, particularly testosterone. The more active form of this hormone is dihydro testosterone. When this hormone reaches the roots of hair follicle of the person with gene for baldness, the former gets destroyed. This results in hair loss and baldness. As the hormone testosterone is present in males in higher concentration, cases of andro-genetic alopecia is primarily a problem of males. However, some amount of testosterone is also produced by adrenal gland in females. Those female patients with gene for baldness and higher concentration of testosterone in their blood may also develop baldness.
Now the remedy……! If we could just destroy the dihydro testosterone hormone reaching the hair follicles and and damaging them, hair loss could be controlled. There exists a drug named Minoxidil, which can destroy the dihydro testosterone. Of course, if ingested, this could destroy the hormone in our blood stream, but this could result in other side effects like loss of libido and hormonal imbalance. So the better way suggested is direct external application of minoxidil on the scalp. The chemical gets absorbed and destroys the hormone reaching the hair follicles. Thus any further damage is prevented. Moreover, there exists no side effect for this external application. Earlier the intervention, lesser will be the extent of damage. However, the follicles which has already been destroyed before the intervention could hardly be recovered. The loss will be prevented so long as the application of the medicine is continued. If the person, discontinues the medicine, the hormone will again start damaging the follicle resulting in hair loss.
Before falling prey to the broad claims regarding hair regrowth, one should definitely try to understand the science behind and then try the course or spend money.
