    What is Finasteride?

    Finasteride is a drug known as a 5-alpha-reductase inhibitor. It is used in the treatment of male pattern hair loss and an enlarged prostate (benign prostatic hyperplasia (BPH)). It is also the active ingredient in Propecia.

    What is BPH?

    BPH stands for benign prostatic hyperplasia. It is more commonly known as an enlarged prostate. An enlarged prostate is a common problem faced by men as they get older. It is thought to be related to hormonal changes as you age.

    Symptoms of BPH include problems with urination. These can include;

    • Feeling the need to urinate urgently or more frequently
    • Difficulty starting to urinating
    • Difficulty emptying your bladder completely
    • Poor urine stream
    • ‘Stop-start’ flow
    • Urinary incontinence


    How Does Finasteride Work for an Enlarged Prostate?

    A hormone called DHT is associated with an enlarged prostate. DHT is made from testosterone by a chemical called 5-alpha reductase.

    Finasteride is a type of drug known as a 5-alpha reductase inhibitor. This means that it can stop testosterone from being converted into DHT. This helps to stop your prostate from getting bigger and can start to shrink your prostate.

    How Effective is Finasteride for an Enlarged Prostate?

    Finasteride is an effective treatment for enlarged prostate. The levels of DHT in the prostate are reduced by over 90%. In one trial, approximately 50% of men taking the drug experienced a reduction in prostate size of at least 20%.

    What is Androgenetic Alopecia?

    Androgenetic alopecia is the most common type of hair loss in men. It typically causes hair loss in men as they get older. Androgenetic alopecia is also referred to as male pattern baldness. It is caused by the sensitivity of hair follicles to a hormone called DHT.

    DHT is made from the testosterone hormone. Genetics can influence the sensitivity of the hair follicles to this hormone.

    Please note that androgenetic alopecia is not solely found in men! Women can also suffer from various forms of hair loss, including androgenetic alopecia. Unfortunately, women cannot use finasteride to help with their hair loss, due to the effects it has on hormone levels; however, minoxidil and other treatments can be used by women experiencing hair loss (see Alternatives to Finasteride for Hair Loss below).

    How Does Finasteride Work for Hair Loss?

    Finasteride is only used for a specific type of hair loss known as androgenetic alopecia, or male pattern baldness. The DHT hormone responsible for male pattern baldness is made by a chemical called 5-alpha reductase. Finasteride is a 5-alpha reductase inhibitor.

    This means that it blocks the effects of 5-alpha reductase. This stops 5-alpha reductase from converting testosterone into DHT, which helps to protect the hair follicles and reduce hair loss.

    Note that this can produce small amounts of hair growth. Some follicles which had been in senescence previously may be “woken up” by the treatment. However, this does not mean finasteride will help you grow all your hair back! It is best to think of it as keeping the hair you have left, rather than hair regrowth.

    How Effective is Finasteride for Hair Loss?

    One 12-month study found that finasteride tablets effectively treated male pattern hair loss in 80% of the men involved. 17.5% of them did experience some mild side effects when using finasteride.

    Does Finasteride Have Any Side Effects?

    Like all medications, there is a chance you may experience side effects when using finasteride. The most common side effects can include;

    • Decreased libido
    • Erectile dysfunction
    • Enlargement of breast tissue
    • Ejaculation disorders


    These are all related to the way the medication functions. Finasteride reduces the body’s ability to use testosterone, so other hormone-dependent body systems can be affected. In most men, these side effects will be mild, or may pass with time. If you feel they are severe, try talking to your doctor or pharmacist to see what options you may have.

    You can stop taking finasteride; however, it is likely that this will reverse the progress your hair has made during treatment and your hair loss will return over time.

    How Do I Take Finasteride?

    You should take finasteride as instructed by your doctor or pharmacist. Normally, this will be one 1mg pill, taken daily at the same time each day. Should you miss a dose, do not take multiple to “catch up”. Simply skip the missed dose and take the next on schedule.

    Alternatives to Finasteride for Hair Loss

    Minoxidil is a popular alternative to finasteride for hair loss. It typically has fewer side effects and it is applied directly to the scalp rather than taken as a tablet. Minoxidil can also be used by women who are experiencing hair loss – indeed, Regaine has a product specifically designed for women (Regaine for Women).

    Other options for hair loss treatment include hair tattooing, wigs and hair pieces and hair transplants.

    Steroid injections, immunotherapy and antifungal treatments may be used if the hair loss has immune or infective causes.
