Rio de Janeiro, Brazil - April 30, 2021: Blister pack of finasteride pills on hand.

The Finasteride is a great help in case of androgenetic alopecia and also for those undergoing a hair transplant. This drug, whose active ingredient is able to inhibit the enzyme 5-alpha-reductase type II responsible for the transformation of testosterone into DHT, has excellent effects on patients suffering from alopecia.

The intake of finasteride is recommended in cases of androgenetic alopecia and hair transplantation as an aid to combat or slow down hair loss and to avoid the process of miniaturization.

But what are the benefits of finasteride in hair transplantation? We will find out in this article.

What is Finasteride used for?

Finasteride is a drug that can inhibit the enzyme -alpha-reductase type II that converts testosterone into DHT.

Anyone suffering from genetic hair loss knows that DHT is responsible for hair loss in cases of androgenetic alopecia.

The hair bulbs of a person suffering from this type of alopecia are extremely sensitive to DHT and, for this reason, fall out as a result of the action of this metabolite.

Why use Finasteride in hair transplantation?

As we indicated in the previous paragraph, Finasteride is able to inhibit the transformation of testosterone into DHI.  This leads to less hair loss, less miniaturized hair and improvement of the hair that appears healthier and stronger.

But what is recommended in hair transplantation?

Although the choice is always up to the surgeon according to the needs of the patient, let’s see below what are the benefits of finasteride for patients who undergo hair transplantation.

Finasteride before hair transplantation

Doctors often recommend continuing Finasteride prior to hair transplantation Patients who say they are already taking Finasteride at the time of their consultation with their surgeon often do not know if they need to stop taking it or if they will need to continue taking it until the surgery.

Although the choice is always up to the surgeon based on the needs of the patient, studies show that taking Finasteride at least 4 weeks before surgery helps to stop hair loss, increase native hair density and decrease the process of hair miniaturization.

Finasteride after hair transplantation.

It may be necessary or recommended to use Finasteride after hair transplantation. The benefits of taking Finasteride after hair transplantation are many.

First of all, it maintains the density of the native hair in two ways: reducing the miniaturization of the hair and increasing the caliber of the hair.

Thus, a visual effect of increased density and voluminosity is created.

In addition, by reducing the production of DHI and its effect on the hair follicles of the native hair, the hair loss is curbed, thus making possible a reduction or stabilization of androgenetic alopecia. This postpones the need for a second hair transplant to the future or eliminates it altogether.

Obviously, each patient is an individual case and it will always be up to the surgeon to suggest the most suitable postoperative course.

It is therefore important to avoid do-it-yourself methods and to always consult the surgeon and your general practitioner in case of previous pathologies.

How long should Finasteride be taken after a hair transplant?

Although the prescribing time for Finasteride varies from patient to patient and doctor to doctor, there are several studies that show that the ideal period of use of Finasteride after hair transplantation to achieve the best possible benefits is one year.
