How Propecia Works

I'm not a big fan of Propecia because I think avodart is better. However, getting a script for Avodart is not easy so let's take a look at How Propecia works


Reduces DHTa, a key cause of hair loss

PROPECIA significantly reduces DHT, a key cause of hair loss, by inhibiting the formation of DHT in your scalp.

Lowering DHT appears to inhibit the further shrinking of affected hair follicles.

DHT is a substance in the body that can shrink the hair follicle until it no longer produces visible hair. Scientists believe DHT and family history are key factors in hair loss. Learn more about the causes of male pattern hair loss.

DHT shrinks hair follicles. PROPECIA blocks the formation of DHT.


PROPECIA blocks the formation of DHT and, in this way, appears to interrupt the development of male pattern hair loss.

PROPECIA helps reduce further hair loss and regrow visible hair.

PROPECIA is the first and only FDA-approved pill proven to treat male pattern hair loss on the vertex (top of head) and anterior mid-scalp area (middle front of head) in men.

Important Information About PROPECIA

PROPECIA was developed to treat mild to moderate male pattern hair loss on the vertex (top of head) and anterior mid-scalp area (middle front of head) in MEN ONLY. There is not sufficient evidence that PROPECIA works for receding hairlines at the temples.

PROPECIA is for the treatment of male pattern hair loss in MEN ONLY and should NOT be used by women or children.

Women who are or may potentially be pregnant must not use PROPECIA and should not handle crushed or broken PROPECIA tablets because the active ingredient may cause abnormalities of a male baby’s sex organs. If a woman who is pregnant comes into contact with the active ingredient in PROPECIA, a doctor should be consulted. PROPECIA tablets are coated and will prevent contact with the active ingredient during normal handling, provided that the tablets are not broken or crushed.

In clinical studies for PROPECIA, a small number of men experienced certain sexual side effects, such as less desire for sex, difficulty in achieving an erection, or a decrease in the amount of semen. Each of these side effects occurred in less than 2% of men and went away in men who stopped taking PROPECIA because of them.

You may need to take PROPECIA daily for 3 months or more before you see a benefit from taking PROPECIA. If PROPECIA has not worked for you within 12 months, further treatment is unlikely to be of benefit.

PROPECIA can only work over the long term if you continue taking it. If you stop taking PROPECIA, you will likely lose any hair you have gained within 12 months of stopping treatment.

Although results will vary, generally you will not be able to grow back all the hair you have lost.
