Eight Dutasteride Facts You Should Know

What is Dutasteride?

Also called Dutasteride, Dutasteride is a medicine for the treatment of alopecia.

It was originally used in men to treat benign prostatic hyperplasia. It is a non-cancerous growth of the prostate caused by overproducing a hormone called dihydrotestosterone. Among its side effects, it was found to act on the patient’s hair. It favors the thickening of the follicular units and helps to stop hair loss.


How does it work?

Among the main facts about Dutasteride that you should know is that it increases capillary density. It also strengthens the hair and slows its fall. This is because it reverses the hair miniaturization process that causes alopecia.

Dutasteride works in a similar way to Finasteride , another popular anti-hair loss medication. Both are based on the inhibition of the enzyme 5 alpha-reductase, a molecule that transforms testosterone into DHT (dihydrotestosterone).

How is Dutasteride different from other drugs like Finasteride?

Although the mechanism of action of Dutasteride is similar to that of Finasteride, they are nevertheless not absolutely exact. As we said, both are based on the inhibition of the 5 alpha-reductase enzyme. They are selective antiandrogens of the follicular root, inhibiting the action of these male hormones, which are responsible for androgenetic alopecia. Both are very useful as treatments to stop hair loss. Still, however, there are studies that point to Dutasteride being more effective.

What does the treatment consist of?

Dutasteride can also be administered orally, always indicated by a specialist. But it is common for specialists to also use it in intradermal infiltrations . That is, with mesotherapy. Microinjections are performed in the areas affected by hair loss. In addition, they can be combined with other anti-hair loss treatments. For example, interspersed with sessions of treatment with Platelet Rich Plasma (PRP), with the use of Minoxidil lotion or with the taking of Finasteride.

When will I see results?

In this list of eight facts about Dutasteride, we come to the star question: the results. Well, Dutasteride patients begin to notice the results on the health of their hair within just a few weeks of starting treatment.

Does it have adverse effects?

Like any drug, Dutasteride is not without adverse effects. Despite everything, as with Finasteride, the risk of side effects is very low. Some studies place it below 3%. 

Its “bad reputation” is due to the fact that, when taking it as a treatment for benign prostatic hyperplasia, one of the adverse effects that was detected in elderly men was related to sexual activity. Specifically, a decrease in libido or erectile dysfunction while undergoing treatment. 

However, the doses of Dutasteride that are used as an anti-hair loss treatment are much lower. In addition, patients with benign prostatic hyperplasia are usually older and, in any case, these effects of decreased libido or erectile dysfunction were transient.


Can women also use it?

Yes, women can take Dutasteride. Of course, as long as it is with the indication of a doctor. That is, as long as it is prescribed by a specialist. However, you need to be careful in two important respects:

  • You should avoid getting pregnant while taking the medicine.
  • You should avoid becoming pregnant for a period of six months after stopping treatment. 

However, with these precautions, having received mesotherapy with Dutasteride or having taken it orally does not interfere with a possible pregnancy in the future, if it had ended by then. In that case, there would be no problem. 

How can I access this treatment?

The use of Dutasteride to stop hair loss should always be indicated by a specialist in hair treatments such as those of our team at the Hair Clinic.
