Finasteride FAQ's

Finasteride is a hair loss prescription medication, which works by blocking DHT, the hormone responsible for male-pattern hair loss.

What is Finasteride?

Finasteride is one of only two medically approved medications to treat male pattern hair loss; its original brand name was Propecia. The medication works by inhibiting the amount of di-hydro testosterone (DHT) produced in the body, a sensitivity to which can cause hair loss in some men. Successful treatment of Finasteride can prevent and, in some cases, reverse the effects of hair loss. Finasteride is a UK-licensed medication that requires a medical consultation before being administered - Sons offer a free consultation with one of our medical team to assess the treatment plan you need to address your hair loss.

Does Finasteride work?

In short, yes. Finasteride is proven to treat male pattern hair loss in 90% of people who take it as part of a consistent treatment plan. Whilst some The effectiveness of Finasteride is also shown to continue as long as the treatment continues - the medication is clinically proven to be most effective when used in combination with Minoxidil.

What does Finasteride do?

Finasteride is a medicine that treats hair loss in men by inhibiting the conversion of testosterone into the DHT. In male pattern hair loss, DHT causes hair follicles to shrink and eventually die off by a process called miniaturisation in men who are genetically susceptible. This process shortens the hair growth phase, making the follicles finer, shorter and more fragile. In the more advanced stages of this process, the hair follicles no longer grow to the extent that they break through the skin.

How does Finasteride work?

Finasteride works by inhibiting the production of DHT. Here’s the science behind it: Finasteride prevents the effects of an enzyme called Type II 5α-reductase, which converts testosterone into DHT. DHT is a male hormone that binds to the hair follicles, causing hair shrinkage and eventual hair loss in men who are sensitive to it. The reduced amounts of DHT in the body discourages DHT build-up that binds to the hair follicles, and therefore, helps to prevent hair loss.

When is the best time to take Finasteride?

We always recommend the men on our treatment plans to stay regular and consistent with their administration of Finasteride. Setting an alarm to take the tablet in the morning every day is often the most popular way to make sure that you stay on top of your treatment. It’s important to remember, that the more diligent you are with your treatment, the more likely you are to see results.

How to reduce the side effects of Finasteride?

The side effects reported from using Finasteride are thankfully very rare. Common side effects occur in less than 4% of people who take Finasteride. For those people that do experience mild side effects, improvement usually follows after a short while. If they do not, however, we would suggest stopping the medication - thankfully side effects tend only to occur in the first six months of usage and in the vast majority of people resolve on stopping the medication. However, you may try leading a healthy lifestyle of regular exercise and a good diet to help reduce these effects prior to stopping.

Does Finasteride work without Minoxidil?

Yes, Finasteride can work without Minoxidil - up to 90% of men will experience improvements in hair loss by taking Finasteride alone. However, most clinical studies have proven that Finasteride is most effective when taken in combination with Minoxidil. This is due to the fact that Minoxidil helps to increase blood flow to your hair follicles which improves the intake of Finasteride into these areas. This process increases the effectiveness of Finasteride inhibiting DHT and preventing male hair loss.

How to take Finasteride?

The Finasteride included in Sons hair loss treatment plans comes in the form of a 1mg tablet that is taken orally every day. We encourage the men who subscribe to our treatments to take Finasteride at the same time each day - this consistency can improve the effectiveness of the medication and prevents missing a dose. Setting an alarm is an easy way to make sure that you are diligent with taking your Finasteride tablets. If you’re looking to increase the effectiveness of Finasteride, the most effective method is to also take Minoxidil as part of your hair loss treatment.

Is it safe to take Finasteride?

To put it simply - yes, it is safe. Finasteride is a fully licensed UK medication that has been approved by multiple regulatory bodies and undergone numerous clinical studies before hitting the market. Taking Finasteride over longer periods is also considered to be safe - many men take the medication on a daily basis for years without experiencing any issues or problems.

How long does Finasteride take to work?

The time it takes to see results will vary depending on the individual. With 6 month of consistent use, Finasteride will reduce 5-alpha reductase in your body and reduce DHT. You may begin to see results at this point. However, most men will notice significant changes between 12 and 24 months. A great way to keep track of progress is to take pictures of yourself from various angles every few months. This will enable you to objectively compare the progress in the quality and quantity of your hair over longer periods.

How long does Finasteride stay in your system?

Finasteride doesn’t stay in your system for very long once you stop taking it. This is due to the fact that it has a relatively short half-life, i.e. the amount of time that it takes for the medication's active substance in your body to reduce by half. In fact, on stopping the medication it is usually completely excreted after seven days. It is important to note that Finasteride is not a cure for male pattern hair loss and on stopping the tablets your hair loss will begin again - they say you’re usually back to where you started before the medication after approximately one year.

Can Finasteride cause hair loss?

Finasteride can cause a temporary form of hair loss known as shedding, although this may be concerning, this is actually a sign that the medication is working. You will most likely experience shedding in the early stages of your treatment (between 2 and 4 months), this is due to the fact that Finasteride is encouraging follicle rejuvenation. This process activates growth in your hair follicles and forces old hair strands out to make way for new hair to take its place. The hairs that fall out are usually thinner lighter hairs which are replaced by thicker and healthier hairs.

Does Finasteride regrow hair?

Yes, in some cases, Finasteride can regrow hair. Whilst 90% of men who take Finasteride experience improvements in their hair loss, the chances of you experiencing significant hair regrowth are dramatically increased by two factors: • Starting your Finasteride treatment at the early stages of hair loss. • Combining Finasteride with Minoxidil - another hair loss medication. Minoxidil increases blood flow to the scalp and improves the amount of Finasteride that reaches areas where it can make a difference. Additionally, the more hair you have to start with can greatly improve the effectiveness of hair loss medications.

Does Finasteride cause hair loss initially?

Hair loss treatments can cause some initial shedding of hairs but don't panic, this is actually a sign of the medication working. As your hair follicles are rejuvenated by hair loss treatments, older miniaturised hairs are pushed out of the scalp to make way for new hair. This is known as shedding and usually occurs in the early stages of treatment (between 2 and 4 months) before you begin to see the noticeable signs of hair loss prevention and usually settles down with continuous usage. Although it can occur with Finasteride, it is more commonly associated with Minoxidil.

Is Finasteride safe?

Yes, Finasteride is safe and has been licensed to treat male pattern hair loss since the 1990s. This medication is one of only two medications that is proven to be effective at treating hair loss. Finasteride is a fully licensed UK medication that has been tested in multiple medical case studies before being approved for use. Less than 4% of the men who take Finasteride for male pattern hair loss experience significant side effects from this treatment and most men take the medication daily for years without any issues at all.

Is Finasteride worth it?

What is the difference between Propecia and Finasteride?

We get this question a lot, but the answer is very simple - they are effectively the same thing.

Once a medication comes off-patent, it tends to be available as a ‘generic’ or unbranded version which tends to be cheaper than the branded Propecia version.
