What is Finasteride?

Finasteride is an effective drug used in the treatment of male pattern baldness. It is the generic version of the well-known hair loss treatment, Propecia. As Propecia lost its patent on manufacturing Finasteride in 2014, this allowed multiple manufacturers to produce the drug. This, in turn, lowered the prices of generic Propecia and has made it a much more affordable option for men who suffer from hair loss. Medically, there is no difference between Propecia and Finasteride as they contain exactly the same active ingredient.

Propecia vs Finasteride

How does Finasteride work?

Finasteride works by preventing testosterone from being converted to the hormone dihydrotestosterone (DHT), which allows the hair follicles to regain their normal size. Studies have shown Finasteride 1mg can increase hair growth, and can also improve how people think their hair looks. In most cases, men will either regrow or no longer lose more hair.

It can take three to six months of treatment with Finasteride 1mg before hair regrowth is seen. The balding process usually resumes within six to 12 months if treatment is stopped. Side effects for Finasteride 1mg are uncommon. Less than one in 100 men who take Finasteride 1mg experience a loss in sexual appetite (libido) or erectile dysfunction.

Finasteride Results

While effectiveness varies from patient to patient, clinical studies have shown that after 5 years of use, 90% of men taking Finasteride will either have more hair, or the same amount of hair as they had at the start of treatment. In comparison, only 25% of men who did not take Finasteride has more or the same amount of hair. 

It will usually take at least 2 months for you to notice an effect from taking Finasteride. Hair regrowth can occur for up to 2 years after starting the medication.

Does Finasteride Work

The table below shows how Finasteride works compared to placebo. Placebo pills are used in clinical trials, where a certain group of patients are given "water pills". These contain no drug. 

This allows an accurate control group to assess the effectiveness of the drug in question. With Finasteride, we can see that after 60 weeks of use, 90% of Finasteride patients will have noticed hair regrowth or no further hair loss. This compares to just 23% of placebo patients. 

So in short, yes, Finasteride does work for most patients!

The dose of Finasteride for hair loss is one 1mg tablet daily. It can be taken with or without food. You should not cut the tablets to half dose Finasteride. 

It may need to be taken daily for a number of months before results can be seen. If you forget to take a tablet, skip the missed dose and take the next one at the usual time.

Some patients ask about using Finasteride 5mg tablets and cutting these tablets to achieve a 1mg dose. This is not recommended, as the quartering of tablets is imprecise with the size of the tablets, and the correct dosage cannot be guaranteed. 

Alternatives to Finasteride

If you are concerned with the side effects of Finasteride, or simply want to try something else, Regaine Extra Strength is a topical treatment that has been shown to be successful in treating hair loss in men. While not as effective as Finasteride, it does provide an alternative for men wishing to try something else.

Regaine contains minoxidil 5% and is available as foam or lotion. It is applied twice daily to the scalp. When taking Finasteride or Regaine, you must continue to use them to prevent the reversal of their effects. Regaine and finasteride 1mg can be used together. Regaine is also often recommended to patients who have undergone hair transplant procedures to help improve the rate of growth of hair.

Topical Finasteride

There is currently research being performed on a topical version of Finasteride. This is when instead of taking Finasteride by mouth, it is instead made in liquid form and applied directly to the scalp. Research is ongoing for this treatment, and the product is not currently licensed in the UK. Find out more about topical finasteride in 'Topical Finasteride vs Oral Finasteride'Regaine is a topical product that is currently licensed in the UK for hair loss.

Finasteride and Minoxidil

As well as oral Finasteride, topical Minoxidil is available in the UK. We provide the branded version of Minoxidil, Regaine Foam. 

It's perfectly safe to use both treatments simultaneously and is often recommended to get the best results for hair regrowth.

Finasteride Side Effects - A Complete Breakdown



What is Finasteride?

Finasteride (finasteride) is a prescription-only hair loss treatment. It’s not available on the NHS so you need a private prescription. Alternatively, you can make a private appointment with your GP. We can also generate this at no extra cost when you complete your online assessment, and pay for your treatment. It is only suitable for men and should never be taken by women.

What is Finasteride used for?

Finasteride 1mg Tablets are used as a treatment for hair loss in men.

How To Take Finasteride?

Take ONE tablet once a day, with or without food.

How Effective Is Finasteride?

9 out of 10 men notice an improvement in their hair loss and the most men stop losing their hair, and some will also see regrowth of hair. Studies were made in men aged 18-41 with mild to moderate hair loss. On stopping Finasteride, hair loss will usually resume after six to twelve months.

How Does Finasteride Work?

Finasteride blocks the action of 5α-reductase, a hormone that affects hair growth in men.

How Long Does Finasteride Take To Work?

Due to the hair growth cycle, it generally takes 3-6 months for you to see the benefits of Finasteride. If you have not noticed any effect over this time, you should stop taking the medication.

What are the side effects of Finasteride ?

Side effects are uncommon and usually mild, but sometimes Finasteride can cause skin rashes. A concern for many men is that it can reduce sex drive and cause erection problems. Around 1.5% of men are affected by these side effects, which, in very rare cases, can continue to cause problems after stopping the medication.

What is the difference between Propecia and FInasteride?

Medically, Propecia and Finasteride (or ‘Generic Finasteride’) are equivalents. They both contain the active ingredient Finasteride 1mg.

Will Finasteride help an area of complete baldness?

No. Finasteride will only be effective on areas of the scalp that still have some hair growth. Finasteride will not regrow hair on completely bald areas.

Does Finasteride cause depression?

While rare, depression is a possible side effect of using Finasteride. This can also lead to suicidal thoughts. If you feel depressed when taking finasteride, stop taking the medication and see your GP.

Is improvement with Finasteride permanent?

Unfortunately not. You need to continue to take the medicine in order to maintain the effects. Once treatment is stopped, hair loss usually resumes.

Is Finasteride available on the NHS?

No. As this treatment is generally a cosmetic treatment, the NHS do not prescribe this medication for hair loss.

Does Finasteride work in women with hair loss?

No. The process by which women lose their hair is different from that in men. Finasteride will not be effective in reducing or stopping this, and should not be taken by women. In addition to this, Finasteride can cause serious side effects in women, particularly those who are of childbearing age.

Can I take a higher dose of Finasteride for quicker results?

No. Increasing the dosage has no effect on improving results. This will only increase the risk of serious side effects.
