Until just a few years ago, hair loss was often dismissed as something that could happen as time passed and people grew older.

However, recently there have even been reports that the number of people experiencing this condition has surpassed 10 million, and more than half of them are said to be in their 20s and 30s.

As a result, hair loss is now seen as no longer a disease that can occur only in middle-aged and older men, but as a social condition that can affect anyone regardless of age or gender and can arise at any time for a variety of reasons. Awareness of how serious it is has spread to the point where people are asking whether it should be viewed as a social disease.

That shows how the concept of hair loss has changed.

It can be caused by many factors, including hereditary influences from family history, severe stress caused by excessive work or study, irregular eating habits and lifestyle patterns that could not be properly managed due to a busy daily routine, and air and environmental pollution such as ultrafine dust.

These factors can cause natural hair to fall out and leave thinning areas in various places, becoming a psychological or physical concern and lowering confidence in one’s appearance, which can make normal social activity difficult. People try to find and attempt ways to improve the situation and escape the negative circumstances, but while such methods may have temporary effects, they are difficult to use to address the root cause.

Among the management methods, there are products that are relatively easy to access and simple to use. One of them is the topical hair loss medication whose effect many people look into. It is a medicine applied to the area of concern once or twice a day in liquid or foam form.

A representative product is minoxidil (Rogaine). Originally, as a topical hair loss medication, it was used as a vasodilator and as a treatment for high blood pressure, but during clinical use it was found that after taking it, hair grew on the head, arms, and legs, so it was developed and used as a hair-growth agent. Therefore, if you have cardiovascular disease or low blood pressure, it is advisable to visit a medical institution and consult first before using it if possible. Also, unlike oral medication, it is known to be less effective especially for M-shaped hair loss, and it is mainly recommended for use around the crown area and for cases where hair that was once thick and strong has become thin and turned almost like peach fuzz.

And perhaps the most important point is that, because hair loss literally means hair falling out, the focus is not on preventing it from falling out, but on the hair-growth effect that helps it grow back again. Using the effect of a topical hair loss medication helps relax blood vessels and prevents follicles from shrinking, stimulating hairs in the resting phase and promoting new hair growth.

The effects of a topical hair loss medication are said to vary from person to person. It may work well for some, while in the opposite case it may have no effect at all. However, if you are generally in the early stages and use it consistently for about 3 to 6 months, the effect is said to gradually become noticeable. That said, if the hair loss itself has already continued for a long period of time, even if you apply the medication, it may not have the expected effect at all, so please keep this in mind.

The effects one may hope for when using minoxidil include increasing blood flow to promote hair growth in the follicles and increasing the number of follicles in the growth phase while reducing those in the resting phase. It also expands blood vessels in the cell membrane, inhibits calcium influx into cells, and helps activate DNA synthesis. Sometimes people expect results from a topical hair loss medication but instead complain that their hair is falling out even more. Since this is a medication whose effects appear gradually and require at least 3 months of use, if the long-awaited results are minimal or if there are signs of this kind of loss, you may worry about whether to continue using it.

This is due to the shedding phenomenon, which usually appears around 2 to 6 weeks after starting, and the reason for this is said to be the hair growth cycle.

In brief, natural hair has a cycle in which, when the growth phase ends, it goes through a regressive phase for about 3 weeks, then a resting phase for about 3 months, and then returns to the growth phase.

As mentioned above, you can think of it as a function that shortens the resting phase and supports hair growth during the growth phase, so even if it appears as though hair is falling out to the naked eye, that is not actually the case.

It is safe to view this as evidence that the natural hair cycle is returning to normal, so there is no need for excessive concern. Although this is a medicine with many advantages, just as each person’s condition and characteristics are different, the presence or absence of side effects will also differ.

Representative side effects include skin-related symptoms such as itching, dryness, and inflammation, as well as hypertrichosis on the eyebrows or forehead, intraocular pain, reduced vision, redness of the eyes, and various cardiovascular symptoms. These do not happen unconditionally, but since they may occur depending on the case, if such symptoms appear, it is necessary to stop using it immediately and visit a nearby medical institution to check the symptoms.

If you have continuously used a medicine in order to get the effect of a topical hair loss medication but still have not achieved the satisfying results you were waiting for, then because this condition can worsen over time, it may be time to consider other measures. With that in mind, it may also be a good choice to visit a related clinic without delay and look into ways to address the issue.
