Start Your Expert Consultation
Finasteride, the generic version of Propecia, is a clinically proven treatment for male pattern baldness (androgenetic alopecia) (NICE, 2022). It works by blocking the conversion of testosterone into dihydrotestosterone (DHT), a hormone linked to hair thinning.
Finasteride is taken as a daily tablet and is designed to slow hair loss and support regrowth in men with mild to moderate hair thinning, particularly at the hairline and crown. In clinical studies, around 9 in 10 men saw positive results, making it a widely recommended option for preserving and restoring scalp hair.

Key Facts About Finasteride
What is Finasteride?
Finasteride is a prescription-only medicine used to treat male pattern hair loss and benign prostatic hyperplasia (BPH). It is most commonly taken as a 1mg daily tablet to reduce hair loss and encourage regrowth in men. The branded version is Propecia, but generic Finasteride offers the same benefits at a lower cost. It may also be prescribed off-label for other uses, such as hormonal therapy in transgender women or excessive hair growth in women (Leinung et al, 2018).
How Does Finasteride Work?
Finasteride works by blocking the enzyme 5α-reductase, which converts testosterone into dihydrotestosterone (DHT). High levels of DHT shrink hair follicles, leading to hair loss. By lowering DHT, Finasteride helps protect hair follicles, slow down thinning and promote regrowth (Anitha et al, 2009; Kaufman & Dawber, 1999; Rossi et al, 2011).
What is DHT?
Dihydrotestosterone is a male hormone responsible for characteristics like a deeper voice and body hair (Kinter et al, 2023; Society for Endocrinology, 2021). In adulthood, too much DHT can damage hair follicles and contribute to baldness (Ntshinila et al, 2023). Finasteride lowers DHT levels to help prevent further hair loss (Ustuner, 2013).
What Are the Benefits of Taking Finasteride?
Finasteride is clinically proven to slow hair loss and stimulate regrowth in many men with male pattern baldness. In a study of 326 men, daily use of 1mg Finasteride significantly improved hair density, especially at the crown and frontal scalp (Leyden et al, 1999). Many users report increased confidence and improved self-esteem.
How Long Does Finasteride Take to Work?
DHT levels start to drop immediately after starting Finasteride, but visible results typically appear after 3 to 6 months. For best results, it should be taken consistently for 6 to 9 months. Stopping treatment can lead to hair loss resuming (Kaplan & Olsson, 1996).
How Effective Is Finasteride?
Finasteride is one of the most effective treatments for male pattern hair loss. Clinical studies show that 90% of men who took Finasteride for 5 years either regrew hair or maintained their current hair, compared to only 25% in the placebo group (Zito et al, 2023). Maximum results may take up to 2 years (Eur J Dermatol, 2022).
Finasteride vs Placebo
Finasteride | Placebo | |
---|---|---|
% Satisfaction (5 Years) | 63% | 20% |
% Regrowth or No Hair Loss | 90% | 25% |
In short, Finasteride is a well-established, evidence-based option for treating male hair loss and works best when taken consistently over time.
Directions
How do I take Finasteride?
Take one 1 mg Finasteride tablet once a day, ideally at the same time. Swallow it whole with water. You can take it with or without food. Do not crush or chew the tablet.
If you miss a dose and remember within 6 hours, take it as soon as possible. If more than 6 hours have passed, skip the missed dose and take the next one at the usual time. Never take two doses at once.
Missing the occasional dose is unlikely to affect your progress, but daily use gives the best results.
How do I use Finasteride correctly?
Always follow your prescriber's advice and read the patient leaflet. Take one tablet daily, without breaking or crushing it. Most men begin to see results in 3 to 6 months, but it can take up to 9 months. Your doctor will check your progress and let you know whether to continue treatment.

How long should I take Finasteride?
You should keep taking Finasteride as long as you want to maintain your results. It is safe to use long-term if your doctor agrees. Most men see full results within 6 to 12 months.
If you stop taking it, new hair growth will be lost and your hair may return to its pre-treatment state (Patel, R.; 2023).
What happens if you stop taking Finasteride?
Results usually peak after 2 years of consistent use. If you stop treatment, you may begin losing new hair within 6 to 12 months, returning to your original pattern of hair loss.
How should I store it?
Keep Finasteride in a cool, dry place away from children. Do not use it after the expiry date shown on the packaging. Never dispose of medicine in household waste or down the sink. Ask a pharmacist how to safely throw away unused medicine.
Which Finasteride dosage should I take?
For hair loss, the typical dose of Finasteride is 1mg once daily. It can be taken with or without food, at any time that suits your routine. Consistency is key to achieving the best results.
What Should I Do If I Miss a Dose?
If you miss a dose:
- Less than 6 hours late: Take it as soon as you remember.
- More than 6 hours late: Skip the missed dose and take your next tablet at the usual time.
Never take two tablets to make up for a missed dose. If you frequently forget, consider setting a daily reminder or speak to your doctor for advice on staying on track.

Finasteride FAQs
Below UK Meds answer the most commonly asked questions from our patients about Finasteride:
How long should I take Finasteride to see results?
Most users notice reduced hair loss within 3 to 6 months. Full results can take up to 12 months (Nestor et al, 2021). Even if regrowth is limited, the treatment may still prevent further hair thinning (McClellan & Markham, 1999).
Will Finasteride regrow all my hair?
Finasteride helps stop further hair loss and may promote regrowth in thinning areas, especially at the crown. Around 30% to 60% of users experience visible improvement, but full regrowth is rare.
Does Finasteride increase testosterone?
Finasteride can cause a small rise in testosterone by blocking its conversion to DHT, the hormone linked to hair loss and prostate growth (Roehrborn et al, 2003). This increase is usually modest.
Can Finasteride cause erectile dysfunction?
Some men experience side effects like reduced libido, difficulty getting or keeping an erection, or changes in ejaculation. These are generally uncommon but may persist after stopping treatment. Speak to your doctor if concerned.
Does Finasteride affect fertility?
It may impact sperm quality in some men. If you're trying to conceive or your partner is pregnant, use protection and discuss any concerns with your doctor.
How long does Finasteride stay in your system?
The drug itself has a short half-life (6 to 8 hours), but its effect on hormone levels may last up to two weeks after stopping. Hair loss typically resumes within 9 to 12 months if treatment is discontinued.
Can women take Finasteride?
Finasteride is not suitable for women, especially during pregnancy, due to the risk of birth defects. In rare cases, a specialist may prescribe it for other hormone-related conditions, but this is uncommon.
Can I take Finasteride while trying to conceive?
Finasteride may affect sperm quality. It's best to speak to a healthcare professional if you’re trying to have a baby, as stopping treatment may be advised temporarily.
Does Finasteride affect urination?
Yes, it’s also used to treat enlarged prostate (BPH), which can improve urinary symptoms like frequent or urgent urination (McConnell et al, 1998; Tackling et al, 2010).
Does Finasteride cause weight changes?
There’s no strong evidence that it causes weight loss or gain. Everyone responds differently, so speak to your doctor if you notice unexpected changes.
Does Finasteride cause cancer?
The link between Finasteride and cancer is still being researched. Some rare cases of prostate or male breast cancer have been reported, but there’s no confirmed causal relationship (GOV.UK, 2014; Anitha et al, 2009). Always raise any concerns with your GP.
Does Finasteride affect beard growth?
It mainly targets scalp hair. Current research suggests it doesn’t significantly affect facial hair or beard thickness, but more studies are needed (Inadomi, T.; 2014).
Is Finasteride safe?
Yes, when prescribed correctly, Finasteride is considered safe. It is approved by the MHRA for hair loss and prostate conditions but is not suitable for women or those under 18.
Will I lose my hair again if I stop taking Finasteride?
Yes. Any benefits gained may reverse within 9 to 12 months after stopping treatment, so ongoing use is recommended for lasting results.
Do I need Finasteride after a hair transplant?
While not essential, continuing Finasteride after a hair transplant can help protect existing hair and maintain the results of the procedure.
Are there non-medical alternatives to Finasteride?
Yes. Options include hair transplants, wigs, styling products, and camouflage techniques. Surgical options may still require medical treatments like Finasteride or Minoxidil to maintain results.
What is the difference between Finasteride and Propecia?
Propecia is the branded version of Finasteride. Both contain the same active ingredient and work identically, but generic Finasteride is typically more affordable.
Alternative Hair Loss Treatments
Looking for other options besides Finasteride? Regaine Extra Strength is a clinically proven topical treatment for male pattern hair loss. It contains 5% minoxidil and is applied directly to the scalp as a foam or lotion, usually twice a day. While it may be slightly less effective than oral Finasteride, it offers a non-tablet alternative.
Regaine can be used on its own or alongside Finasteride to improve results. This combination is often recommended to boost hair regrowth, especially after a hair transplant. To maintain any gains, both treatments need to be used consistently.
Can You Use Finasteride and Minoxidil Together?
Yes, it's safe to combine Finasteride tablets with Regaine (minoxidil). Using both together can lead to better results than using either treatment alone.
Topical Finasteride
Topical Finasteride, a liquid version applied directly to the scalp, is still under research and not currently licensed in the UK. At the time of writing, Regaine remains the only approved topical product for treating hair loss.
Lifestyle and Hair Loss
Hair loss is influenced by hormones like DHT, which Finasteride reduces. However, lifestyle factors also play a role. Maintaining a healthy weight may support hormonal balance and scalp health. In some cases, medications like Mounjaro may help with weight loss and contribute to an overall wellbeing plan that supports hair retention, speak to a healthcare provider to check if this could be a solution for you.
