Finasteride and It’s Uses

Reading time -

Finasteride, a widely recognized medication in the world of men's health, has garnered significant attention for its effectiveness in addressing various health concerns. Primarily prescribed for the treatment of androgenetic alopecia (male pattern hair loss) and benign prostatic hyperplasia (BPH), Finasteride has become a go-to solution for many men seeking relief from these common conditions. 

Here, we delve into the specifics of Finasteride, exploring its primary uses, dosage frequency, the time it takes to start yielding results, and potential complementary treatments that can enhance its efficacy. With a unique and masculine approach, we aim to provide a comprehensive understanding of this medication, empowering men to make informed decisions about their health.

What is Finasteride?

Finasteride is a synthetic medication that belongs to the class of drugs known as 5-alpha reductase inhibitors. It was initially developed to treat benign prostatic hyperplasia (BPH), a non-cancerous enlargement of the prostate gland that can cause urinary symptoms in men. Later, it was also found to be effective in treating androgenetic alopecia, commonly known as male pattern hair loss.

Finasteride works by inhibiting the enzyme 5-alpha reductase, which is responsible for converting testosterone to dihydrotestosterone (DHT). DHT is a potent androgen hormone that contributes to hair follicle miniaturization in genetically susceptible individuals, leading to hair loss. In the case of BPH, DHT stimulates prostate growth, which can result in urinary symptoms. By reducing DHT levels, Finasteride can slow down hair loss, promote hair regrowth, and alleviate the symptoms of an enlarged prostate.

What is Finasteride Used For?

Finasteride is primarily used for two main purposes:

Androgenetic Alopecia (Male Pattern Hair Loss)

Finasteride is commonly prescribed to treat male pattern hair loss, a hereditary condition characterized by hair thinning and receding hairlines. By inhibiting the conversion of testosterone to dihydrotestosterone (DHT), Finasteride helps reduce hair follicle miniaturization, slowing down the progression of hair loss and, in some cases, promoting hair regrowth. 

It is important to note that Finasteride is approved for use in men only and is not recommended for women, particularly those who are pregnant or may become pregnant, due to potential risks to fetal development.

Benign Prostatic Hyperplasia (BPH)

Finasteride is also used to treat BPH, a non-cancerous enlargement of the prostate gland that can cause urinary symptoms such as frequent urination, difficulty starting urination, weak urine flow, and the inability to completely empty the bladder. By lowering DHT levels, Finasteride can help shrink the enlarged prostate, alleviate urinary symptoms, and reduce the risk of acute urinary retention or the need for surgical intervention.

Although primarily prescribed for these two conditions, Finasteride may be used off-label for other purposes under a doctor's supervision. It is essential to consult with a healthcare professional before using Finasteride to discuss potential benefits, risks, and appropriate dosage.

How Often Does Finasteride Need To Be Taken?

Finasteride is typically taken once daily as an oral tablet. The standard dosage for treating male pattern hair loss is 1 mg per day, while the dosage for treating benign prostatic hyperplasia (BPH) is usually 5 mg per day. It is important to follow the prescribed dosage and instructions provided by your healthcare professional.

Consistency is key when taking Finasteride, as regular use is necessary to maintain its effectiveness. If you miss a dose, it is advisable not to take an extra dose to make up for it; instead, continue with your regular schedule. Discontinuing the medication or irregular use may result in the reversal of its effects, leading to a return of hair loss or BPH symptoms. Always consult with your doctor before making any changes to your medication regimen.

How Long Until It Starts Working?

The time it takes for Finasteride to start showing results varies from person to person, and it largely depends on the condition being treated.

Androgenetic Alopecia (Male Pattern Hair Loss): When treating hair loss, it generally takes about 3 to 6 months for Finasteride to show noticeable improvements, such as reduced hair loss or increased hair growth. In some cases, it may take up to 12 months to see the full benefits of the medication. It is crucial to be patient and consistent with the treatment, as results may not be immediately visible.

Benign Prostatic Hyperplasia (BPH): For BPH, Finasteride may start to alleviate urinary symptoms within a few weeks, but it can take up to 6 months or longer for the full benefits to become apparent. As with hair loss treatment, patience and consistency are essential to achieve optimal results.

Treatments You Can Combine with Finasteride To Increase Its Efficacy

Combining Finasteride with other treatments may help enhance its efficacy for both androgenetic alopecia (male pattern hair loss) and benign prostatic hyperplasia (BPH). Here are some treatments that can be combined with Finasteride:


For male pattern hair loss, Minoxidil is a topical solution or foam that can be applied directly to the scalp to promote hair growth. It is an FDA-approved treatment for hair loss and works by increasing blood flow to the hair follicles, stimulating growth. Combining Finasteride and Minoxidil may provide synergistic effects, potentially yielding better results than using either treatment alone.

Low-Level Laser Therapy (LLLT)

LLLT is a non-invasive treatment option for hair loss that uses red light to stimulate hair follicle growth. It can be administered through devices like laser combs or helmets. When used alongside Finasteride, LLLT may help enhance hair growth by providing an additional growth stimulus to the hair follicles.


For BPH, alpha-blockers are a class of medications that can be combined with Finasteride to further improve urinary symptoms. Alpha-blockers work by relaxing the smooth muscle in the prostate and bladder neck, making it easier to urinate. Common alpha-blockers include tamsulosin, alfuzosin, and terazosin. Combining Finasteride with an alpha-blocker may provide better symptom relief than using either medication alone.

Lifestyle Changes

Incorporating healthy lifestyle habits, such as maintaining a balanced diet, exercising regularly, and managing stress, can support the overall efficacy of Finasteride. For BPH, in particular, avoiding excessive caffeine and alcohol, staying physically active, and practicing bladder training techniques can help alleviate urinary symptoms.

Before combining any treatments with Finasteride, consult your healthcare professional to ensure that the combination is safe and appropriate for your specific condition.
