What is Finasteride and how does it work?

Finasteride is a drug that slows and controls hair loss by acting on the root of the problem, this drug inhibits the production of the enzyme 5-alpha-reductase (type II) making part of the testosterone can not be transformed into dihydrotestosterone. Trade name (Propecia 1mg) is approved by the FDA (Food and Drug Administration).

Treating androgenic alopecia with Finasteride

Androgenic alopecia is known to be a process of miniaturization and progressive thinning of the hair, caused by sensitivity to the action of the hormone DHT (dihydrotestosterone) in the hair follicle.

How should Finasteride be taken?

Finasteride is taken in the form of 1 tablet. It is usually taken once a day, with or without food. Take 1 finasteride capsule at about the same time every day. 

Follow the directions on your prescription label carefully and ask your doctor or pharmacist to explain any parts you do not understand. 
Take finasteride exactly as directed. Do not take more or less, and do not take it more often than directed by your doctor.

Relationship of Finasteride to the hormone DHT (dihydrotestosterone)

The hormone DHT is a by-product of testosterone, it is present in all humans. To have DHT in the body, testosterone must be converted through a chemical reaction, and this transformation requires the help of the enzyme 5-alpha reductase type II.

Thanks to the treatment with Finasteride (propecia 1mg) the enzyme 5-alpha reductase type II is selectively inhibited, decreasing the amount of DHT in the body available. 

With Finasteride, it is theoretically possible to stop the process of hair loss and miniaturization. 

Long-term results of Finasteride

It takes approximately 6 months of treatment to begin to see results. 

Typically, the patient begins to notice the results of finasteride on the hair after 4 to 6 months of hair treatment. The main effects it causes in the first results are a loss of hair and then an increase in hair density.

With approximately 1 year of continuous daily treatment the patient reaches maximum hair density and then enters a maintenance phase of the results. If you have been taking finasteride for 12 months and there has been no improvement, it is probably not a good idea to continue treatment. Ask your doctor whether or not you should continue treatment.

Long-term results of Finasteride

Side effects of Finasteride

Side effects of the drug (Finasteride) most often occur only during the use of the medication. Therefore, on withdrawal of treatment for 6 months or more the hair will fall out again. 
If patients experience any side effects, they will also probably disappear when they stop taking the medication.

Some of the few side effects are usually related to sexual libido in a minority of patients:
- decreased sexual desire 
- decreased sperm count or low volume of ejaculated semen.

These effects occur in a small percentage in men and it is suspected that there is a strong emotional component involved, as in the scientific studies, 1.8% of men taking finasteride complained of decreased libido, while 1.3% using placebo complained of the same.
In any case, the change in libido seems to diminish with continued treatment and disappears completely after discontinuation.
Finasteride may cause other side effects. Call your doctor if you have any unusual problems while taking this medication.

Finasteride Use Conclusions

Finasteride only slows hair loss while taking the medication. Continue taking finasteride, even if you already notice an improvement. Do not stop taking finasteride without consulting your doctor. Hair that has grown while taking finasteride is likely to fall out in the first 12 months after stopping the medication.

It is vitally important to consult a physician before starting treatment with finasteride. 

Only the doctor, through a hair analysis and sometimes with the help of blood tests can evaluate your case and determine the causes of alopecia and if finasteride is the solution to the alopecia suffered by the patient.

In summary, we believe that finasteride is an effective and safe drug for the treatment of androgenic alopecia.
