Minoxidil was introduced in the early 1970s for the treatment of hypertension. Among the side effects found on patients undergoing this treatment, experts noted a phenomenon of hypertrichosis (widespread increase in hairiness). It was for this reason that dermatologists later identified minoxidil as a possible treatment for hair loss.
In healthy subjects, the systemic use of minoxidil was not considered due to the side effects caused (above all, hypotension). For this reason it was decided to use minoxidil in topical formulations. Since then, its use in the prevention and treatment of baldness has gradually established itself. Since 1990, minoxidil has been approved by the Italian Ministry of Health.
How Minoxidil Works
As mentioned, the studies carried out so far have not been able to define with certainty the way in which minoxidil acts on hair growth. The most accepted hypothesis, however, is that this drug tends to prolong the anagen phase of the hair (click here to find out more).
The thickening and strengthening action carried out by Rogaine women foam begins to be visible after about 90-120 days from the beginning of the treatment. In fact, this is the time span that the drug takes to act on the hair. In the initial phase of the treatment there is a more pronounced fall, defined as induced fall, which however represents a physiological phenomenon. This phase is followed by noticeable hair growth.
How minoxidil is used
Thanks to the formulation Rogaine minoxidil for women in lotions and foams, the application of products based on minoxidil is very simple. The most important thing is to distribute the product evenly over the entire area affected by baldness. Amount of product and frequency of application must be established by the specialist or following the instructions on the package leaflet of the drug used.
Effectiveness and results
As already mentioned, the first visible results from the use of minoxidil are noticeable after 90-120 days. Some studies have shown that the effects are more evident in the vertex of the head, rather than in the frontal region. In subjects who respond positively to the treatment, there is an increase in the diameter and length of the hair.
After the first 3-4 months, always following the instructions of an expert (dermatologist or trichologist), it is possible to pass from a shock therapy to a maintenance one. In this step it is possible to reduce the dosage and frequency of application. The key is not to stop treatment abruptly. The beneficial effects of minoxidil on hair are in fact not definitive but temporary and linked to the use of the product. An abrupt stop in the use of the drug quickly returns the patient to the initial condition.
But is minoxidil therefore effective on all subjects? Unfortunately, the treatment does not always produce the desired effects. First of all, it must be said that success is linked to consistency and precision in the applications. The effectiveness is then reduced in people of more advanced age and in those in which the condition of alopecia is already at an advanced stage.
