Finasteride 1mg film-coated tablets

Finasteride 1mg film-coated tablets are an oral treatment for male pattern baldness (hereditary hair loss in men). If your hair is starting to noticeably thin or recede, Finasteride may be a good first treatment option to slow down or stop hair loss.

Hair loss doesn’t need to be inevitable.

Get to know Finasteride for hair loss 

Finasteride is the active ingredient in Finasteride 1mg tablets, available as a prescription-only treatment for hair loss in males and those assigned male at birth. Often referred to as male pattern baldness (Androgenetic or Androgenic Alopecia), hair loss can affect up to 80% of men, often starting before the age of 21 for 1 in 4 men. 

Finasteride key facts

Taking action when you notice changes in hair thickness or balding can result in more effective treatment results when using Finasteride.

  • Can stop hair loss for up to 90% of men who use it
  • Noticeable hair loss improvement within 3-6 months
  • Around 66% of men experienced visible regrowth

Read more about Finasteride in the Patient Information Leaflet that comes with the medication. 

Our expert clinical team are available to chat about your hair loss treatment options. Call us on 01295 262925 or email [email protected]. 

The science behind how Finasteride helps combat hair loss 

Finasteride works by blocking an enzyme called 5-alpha-reductase, which normally converts testosterone into dihydrotestosterone (DHT) in the body. DHT is the hormone primarily responsible for male pattern baldness, as it causes hair follicles to shrink over time in men who are genetically susceptible.

Focusing on the follicles

When Finasteride reduces DHT levels in the scalp (typically by about 65-70%) it helps to protect hair follicles from this shrinking process. This protection allows existing hair to grow normally and can even revive follicles that have begun to miniaturise but haven't yet completely shut down.

Good to know

The medication, taken as a daily 1mg oral pill, gets to work immediately. But you’ll need to take it consistently for at least 3-6 months before noticing decreased hair loss and up to a year before seeing any potential regrowth.

Importantly, Finasteride only works while you're taking it. Once discontinued, DHT levels rise again and hair loss typically resumes within 6-12 months.

Am I eligible for Finasteride hair loss treatment? 

Finasteride is a prescription-only hair loss treatment for hereditary hair loss only (male pattern baldness). This means hair loss that isn’t related to stress, other medications, diet, other medical conditions or hormonal changes. If you’re unsure, your doctor or a hair specialist can help determine the cause of your hair loss.

It’s suitable for men and those assigned male at birth, who are over 18.

What does male pattern baldness look like? 

Typically, male pattern baldness begins at the hairline (the temples) and often looks like an M shape; you will notice it receding over time.

Then, you might spot one of the following characteristics of male pattern baldness:

  • Hair on the top of the head will thin, eventually to the point where it becomes bald
  • Your hair will become shorter and much finer
  • The sides will recede further, producing a horseshoe pattern around the head

If you have established that your hair loss is likely to be hereditary, Finasteride could be suitable for you. 

Remember, our expert team will review your completed consultation to make sure Finasteride is the right hair loss treatment for you. If it isn’t, there are other treatment options available and we’ll let you know which might be suitable for you.

How to use Finasteride 1mg tablets

Finasteride film-coated tablets for hair loss are only available on prescription in a 1mg strength. They should not be used or handled by females, or children under 18 years old. 

How to take Finasteride

One 1mg tablet should be taken daily each morning after breakfast. Swallow it whole with a glass of water.

It can be taken during your breakfast or just after, but it’s important to take it at this time of day to ensure consistent absorption and effectiveness throughout the day. It is best to avoid taking it before bedtime, as it can interfere with sleep for some people.

If you forget to take a daily dose, you can take it as soon as you remember, but only if it is more than 6 hours before your next tablet is due. Otherwise, wait until your next tablet is due to be taken and take the usual dose of one 1mg tablet. Do not double dose to make up for a missed tablet.

How long does it take to work?

Finasteride will start to work in your body as soon as you start taking it, however it can take 3-6 months before you’ll notice any visible results of decreased hair loss. It can take a further year before any potential regrowth is noticeable. If you stop taking Finasteride, the effects will reduce and you’ll likely notice hair loss resuming after 6-12 months. 


Side effects of Finasteride 1mg tablets

Like any medicine, there is a risk of side effects, although not everyone will experience them. It is not uncommon to experience mild side effects when starting a new medicine, which usually disappear as your body gets used to it. 

In rare cases, some side effects can last and you should inform your GP if this is the case. They will then suggest the next steps.

Mental health considerations

You may not notice some changes in your mood and behaviour so it’s very important to tell your friends and family that you’re taking this medicine and that it can have effects on psychological wellbeing. Others may notice changes and help you quickly identify any symptoms that you need to talk to your doctor about.

  • Finasteride has been associated with depressed mood, depression, suicidal thoughts and sexual dysfunction (including decreased sex drive and erectile dysfunction)
  • Before taking Finasteride, inform us if you have any personal history of depression or suicidal thoughts. This does not automatically mean we will not prescribe for you
  • Stop Finasteride 1mg immediately if you develop depression or suicidal thoughts and contact your doctor as soon as possible

Uncommon side effects (may affect up to 1 in 100 people)

  • Decreased sexual drive 
  • Erectile dysfunction 
  • Problems with ejaculation, such as a decreased volume of ejaculate 
  • Depression or mood swings

If you experience the following, stop taking this medicine and contact your GP as soon as possible. If any of them become severe, go to A&E.

  • Swelling of your face, lips, tongue or throat
  • Difficulty swallowing
  • Skin rash, itching, lumps under your skin (hives)
  • Breathing difficulties
  • Lumps, pain, enlargement of the breast (chest) tissue or nipple discharge. These may be signs of a serious condition, such as breast cancer.

These are not all the side effects that can be associated with Finasteride as a treatment for hair loss in males. You should always read the Patient Information Leaflet that comes with your medication. A copy of this will also be in the medication packaging or box.

Finasteride alternatives are available if you are not getting on with this form of treatment, such as Minoxidil foam and spray or topical Finasteride spray. Contact our UK healthcare team, who will be happy to go through the most suitable options with you.

Frequently Asked Questions

What dosage of Finasteride should I take?

Finasteride 1mg is the maximum daily dosage for hair loss.

We strongly recommend against taking more than one tablet daily for hair loss. This will not accelerate the benefits but may cause more side effects.

Can I take 5mg or 10mg Finasteride tablets for hair loss?

5mg Finasteride tablets are prescribed to treat and control prostate enlargement, also known as benign prostatic hyperplasia (BPH). These 5mg tablets are not licensed or intended for hair loss. We only prescribe the licensed medication for male pattern baldness, Finasteride 1mg tablets.

Is Finasteride the best hair loss treatment to start with?

Finasteride is often regarded as the right first treatment to begin fighting male pattern baldness. It has shown some positive signs in up to 90% of patients.

  • The results are achieved by controlling hormones
  • Benefits are gradual, producing a more subtle transformation
  • The costs are low, especially for the generic Finasteride tablets
  • Administering the drug is easy due to its tablet form

Finasteride has more scientific evidence than many alternative treatments on the market. The effects of the active ingredients on hair loss and regeneration are known, making it easier to predict the level of improvement. Most patients prefer ordering generic tablets over branded ones due to their affordability and better value.

Can I take Finasteride for Alopecia?

Finasteride 1mg is a medication used to treat certain types of hair loss (including male pattern baldness also known as Androgenetic Alopecia). There are many other different types of Alopecia, including Alopecia Areata and Traction Alopecia. Finasteride 1mg tablets are only used to treat Androgenetic Alopecia.

Should I use Finasteride with other treatments for better results?

Finasteride UK tablets can achieve results on their own. However, some people like to use them alongside other hair loss treatments. Explore topical non-prescription treatment options including generic Minoxidil liquid or branded Regaine for Men and Alpecin Caffeine Shampoo and Liquid.

Additional supplements, including Biotin - Vitamin B7 – can be taken with Finasteride tablets to promote good health and allow the hormone inhibitions to work at their best. In some cases, hair restoration tonics and creams may be an option.

Where can I find Finasteride before & after pictures?

Our dedicated before-and-after hair loss article provides more information about the hair regrowth process with Finasteride, including customer progress images.

Does Finasteride regrow hair?

Yes, these tablets can help to stimulate hair growth, making hair fuller and thicker.

This treatment is not designed to reverse hair loss entirely. However, in a five-year medical study, 66% of men reported hair regrowth within 6-12 months of using treatment.

Blocking DHT prevents hair follicles from weakening to the point where they no longer penetrate the surface of the scalp (which is what causes the presence of no hair, otherwise known as baldness) when generating new hairs.

The inhibition of the DHT hormone can strengthen hair follicles until they break through the skin barrier. One study found that 65% of long-term users noted an increase in hair count at the five-year mark. This is combined with the thickening of hairs that can also produce the appearance of a thicker head of hair.

What happens when you stop taking Finasteride?

Because it blocks the specific enzyme responsible for DHT, it only prevents hair loss while the drug is active in the body. Once you stop taking the tablets, your body converts testosterone to DHT again, and your hair follicles will start to react normally.

In other words, Finasteride will only work as long as you keep taking it daily.

Does Finasteride lower testosterone?

No, Finasteride does not affect testosterone levels; while it is not uncommon to get a slight increase in testosterone when you first start the medication, this is short-lived and levels should go back to normal.

These tablets prevent testosterone from converting to dihydrotestosterone, the hormone that causes hair loss.

Can women take Finasteride hair loss treatments?

No, this is not recommended. We suggest that women seek female-specific hair loss treatments.
