    Finasteride is well known for halting hair loss, and it is also shown to be effective in regrowing thin hair too.

    In this article, we put a spotlight on Finasteride’s ability to regrow hair and stop hair loss, discussing how it works, its results and other non-surgical hair loss treatment options. 

    What is Finasteride?

    Finasteride is a popular non-surgical hair loss treatment that comes in tablet form. It is also sold under the brand name Propecia® in the UK, where it is available on prescription. 

    Finasteride treats androgenetic alopecia, also known as male pattern baldness. In studies, it has been shown to slow down or stop hair loss and encourage hair growth.

    Research has shown that Finasteride is effective in increasing hair growth and preventing hair loss in >85% of users. Finasteride is suitable for men over the age of 18 and is not typically prescribed for women or children. You may not be suitable for Finasteride if you:

    • Have bladder problems
    • Have liver issues
    • Are trying for a baby or your partner is pregnant
    • Have had an allergic reaction to Finasteride

    How does Finasteride work?

    Finasteride reduces the amount of dihydrotestosterone (DHT) in the body. DHT is a hormone that has been shown to cause hair to thin and fall out in the condition of male pattern baldness. By decreasing the amount of DHT in the body, Finasteride can treat male pattern baldness by preventing ongoing hair loss and thickening thin hair.

    Does Finasteride regrow hair?

    Finasteride can be used to regrow hair, and in clinical trials, has been shown to be effective in increasing hair growth. Research shows that 66% of men saw an increase in their hair growth after taking Finasteride for two years. The study made its assessments using standardised clinical photographs.

    However, while Finasteride is effective in slowing hair loss and supporting regrowth, it is important to understand that the treatment doesn’t work for everyone. It also won’t change the quality of hair in every user, although some people have reported that their hair became thicker and stronger after using Finasteride.

    How long does Finasteride take to work?

    So how long does Finasteride take to work for hair loss? Finasteride results are not immediate and that is because it takes months for the hair to grow. The time it takes to see results can depend on how severe your hair loss is. Despite results taking time, Finasteride gets to work straight away, lowering your DHT levels. When taken daily, Finasteride restricts DHT production and slows hair loss. A study has shown that Finasteride lowers the DHT levels in your body by around 70%.

    Initial results of Finasteride are typically visible after three to four months of taking the treatment, although in some cases, it may take six to nine months. You should understand that Finasteride doesn’t lead to hair regrowth in everyone but is usually effective in slowing your rate of hair loss and that in itself is a huge benefit for most patients. Some users might not see a noticeably fuller head of hair, but rather, their hair will not fall out as quickly. Your hair will continue to fall out – this is the natural growth cycle (most people will lose 50 to 100 hairs per day). The full effect of Finasteride is usually seen after around a year of daily use. 

    Below is a general timeline of hair growth stages for Finasteride users:

    1 day: Finasteride starts to work, blocking DHT production, lowering DHT levels, and beginning to accumulate in your system.

    1 week- 3 months: Initially Finasteride will make your hair shed as it “resets” the hair growth cycle” .This is temporary and is an indication that the medication is working

    3 to 4 months: It’s during this period when you will typically start to see the effects of Finasteride. You may notice a slowing of your hair loss, and in some cases, hair regrowth. 

    9 to 12 months: By now, the full effect of Finasteride should be visible. Even if the treatment doesn’t improve the thickness of your hair, or hairline, you should have experienced a halting of hair loss, so long as you’ve been taking the drug on a daily basis. 

    How to improve Finasteride results

    How can you improve Finasteride results and get the best results from the medication? The first thing to get right is the regularity with which you take the treatment. You should take Finasteride as directed by your Surgeon and it relies upon the medication being taken regularly. Avoid long stretches of the medication not being taken. 

    There are also ways of managing your hair that can give Finasteride the best chance of being effective. Avoid harsh hair products and limit stress exposure. To speed up Finasteride results, you may want to give your scalp a daily massage or take biotin supplements, which could make hair grow faster and thicker

    Finasteride and Minoxidil 

    Minoxidil is a hair loss treatment that comes in a topical solution. Studies show that Minoxidil works by prolonging the hair growth cycle thereby delaying shedding and thinning of hair. You can use both Finasteride and Minoxidil together as a successful treatment for hair loss. Surgeons may recommend taking both products before and after a hair transplant to slow down any further hair loss and encourage hair growth.
