Avoid using finasteride if you are trying to have a baby. Even a crushed tablet should not be touched by your female partner if they are pregnant or planning to be.

Millions of people around the world use finasteride or minoxidil to prevent or even reverse hair loss. Finasteride (generic Propecia) treats benign prostatic hyperplasia (BPH) and androgenetic alopecia (male pattern baldness). They both will be further discussed below.

Finasteride is highly effective in treating hair loss. But, how long before finasteride starts working? You should give it time! It will take months before you begin to see the impact of finasteride on your hair.

What is finasteride?

Finasteride (generic Propecia) is used to treat BPH and reduce its symptoms, such as an increased urge to urinate. But, it's also used to prevent the production of a hormone called dihydrotestosterone (DHT) that destroys hair follicles. 

By taking the finasteride tablets, hair growth will be promoted, and hair loss will stop.

You can purchase finasteride with a prescription in Canada.

If you stop using finasteride, the DHT level gets back to what it used to be, and you most probably start losing hair.

What Is the Mechanism of Action of Finasteride?

How finasteride works is by intercepting the action of an enzyme called 5-alpha-reductase. This enzyme changes testosterone to a hormone that causes the growth of the prostate or hair loss in males. 

In other words, the mechanism of action of finasteride is to increase testosterone levels in the body, decrease prostate size, and increase hair growth on the scalp.

How Long Does It Take for Finasteride To Work?

Finasteride is definitely very effective in stopping or even reversing hair loss. A 1999 study shows that, by using finasteride on a daily basis, hair growth increases significantly. But, you should know that no treatment starts working instantly.

For months, you won't see any visible changes in your scalp. Of course, this is how finasteride works! It helps with stopping hair loss, and months later, you can see the difference. 

How long does it take for finasteride to work? It will take months before finasteride starts to work! Give it time! It's worth the wait.

By using finasteride, three results are possible to happen:

1. Your hair loss will slow down.
2. Your hair wouldn't grow back, but it will stop falling out, and you can maintain the current state.
3. Some of your lost hair will grow back.

Remember that even if you are not going bald, you will lose some hair every day. In fact, it is normal to lose 50 to 100 hairs daily. 

Trials suggest that, after using finasteride, you can see the difference in your hair loss in the third or fourth months of use. Although, it takes six to nine months to see the full impact.
