The most common application of minoxidil is topical, that is, directly on the scalp, in the form of a spray or syringe. It should be applied 1 or 2 times a day depending on the degree of alopecia. It is very important to know that, once the application has been started, it must be maintained for life. If you stop applying it, the hair loss will return. If you look for the price on the Internet you will see that you can get it for around 30 euros and it lasts about three months. It is not excessively expensive, but it is an expense for a lifetime.
In 2019 tests were carried out to take it orally in tablet format. However, the abundant growth of body hair has meant that it continues to be applied much more topically.
Does it act on all types of alopecia?
No. Only on androgenic or androgenetic alopecia, which is caused by genetic factors. It is the most common and has a medical explanation for the presence of the enzyme 5-alpha-reductase and the hormone dihydrotestosterone, which are what cause hair loss. All this causes the follicular unit to weaken so that the hair grows less and less strong until finally it does not grow any more. It has no effect on other pathologies or on scar tissue.
What side effects does minoxidil have?
Minoxidil has a series of side effects that we will explain below:
- Irritation, dryness and flaking of the scalp.
- Hair appears on the face even though it is not applied directly to that area.
- Dizziness or headaches.
- Hair gets dirty quickly. This occurs due to its direct application on the scalp.
All these side effects are reversible when you stop using it.
