If you’re experiencing male pattern hair loss, it’s understandable that you may wish to find a solution that doesn’t unduly interfere with your quality of life. If you don’t want to take an oral medicine, it’s nice to know there’s a topical alternative. Topical finasteride has been shown to both reduce hair loss and, in some cases, promote hair growth.
Finasteride is a commonly used, effective, and well-researched treatment for male pattern baldness [1]. Usually, finasteride is taken orally, as daily medication. But, for those who would prefer a topical treatment, how well does topically applied finasteride work compared to the oral version?
Here we share insights into efficacy, side effects, and potential complications, so you can be well-informed and make the best treatment option for your needs.

Why is finasteride recommended for hair loss?
Male pattern baldness — otherwise known as androgenetic alopecia — is driven by high levels of dihydrotestosterone (DHT), an androgen (male sex hormone) metabolised from testosterone [2].
DHT is necessary for male sex organ development and other key masculine features, including a deep voice [3]. But, in excess, and especially as you age, it can increase your risk of androgenetic alopecia [2]. Your risk is even higher if you are genetically susceptible to hair loss [4].
Elevated DHT is linked to hair loss because it shortens the hair growth cycle and shrinks the follicle size [5].
This is where finasteride comes into play. Finasteride is a 5-alpha reductase inhibitor [6]. This simply means it blocks the enzyme that converts testosterone into DHT. Your DHT levels will reduce if this conversion does not occur, and you can prevent continued hair loss.
How effective is topical finasteride?
We have previously discussed the efficacy of oral finasteride, but what about topical applications? Several studies have explored the effectiveness of topical finasteride in treating androgenetic alopecia, and there have been some promising results [9-11].
If we first look at efficacy alone, multiple clinical trials show that both the oral and topical versions of finasteride have proved effective at reducing hair loss progression and, in some instances, promoting hair regrowth [9-11].
It is important to note that while both treatment forms had a positive impact, the oral version is up to around 20% more effective, but this resulted from just one comparative study [9].
In future studies, it will be helpful to compare dosage, treatment duration, and other variable factors to reach a firm conclusion.
What’s the difference between oral and topical finasteride?
Oral finasteride is usually taken daily, with a typical dosage of 1 mg. This quantity has been proven effective for male pattern baldness and is a commonly used form of the drug [7].
However, you can also take this medication topically, by applying it directly to your scalp instead.
There are differences between the oral and topical forms; oral finasteride is systemically absorbed, meaning it has a ‘whole body’ effect. Essentially, it can impact various organs and systems in your body, from your skin to your liver. After all, it is the oral version of finasteride that is used to treat specific prostate issues at a larger dose, precisely because it can affect your body internally.
However, because oral finasteride impacts DHT levels throughout the body, it also has the potential to cause widespread side effects.
By comparison, topical finasteride is applied only to the scalp. Here, it targets hair follicles directly, while minimising systemic absorption. This has the potential to reduce the systemic side effects that some people experience on oral finasteride, including [8]:
- Low libido
- Issues with getting and sustaining an erection
Ejaculation problems
Therefore, if you wish to reduce or avoid the side effects associated with oral finasteride, you might be interested in the topical application of finasteride. However, always seek medical advice to ensure the treatment suits you.
If oral treatment has potentially greater efficacy, why would someone choose topical finasteride application?
Topical finasteride treatment may cause fewer side effects
Studies looking at the efficacy of topical finasteride also showed a potential reduction in systemic side effects compared to oral finasteride [12].
The mechanism behind this is reduced bloodstream absorption—when the product is applied directly to the scalp, less active medication circulates in the blood, lowering the risk of side effects throughout the body.
Some men may experience localised symptoms such as itching or mild skin irritation on the scalp area where the product was applied [13], but this may be a preferred outcome when compared to erection or ejaculation issues that are among the more serious side effects of finasteride.
What types of topical finasteride are there?
Various formulas contain topical finasteride. However, it is often combined with hair growth-promoting substances like minoxidil, which helps increase the overall efficacy of your treatment. Minoxidil actually boosts the blood flow to your hair follicles, making it a complementary addition to finasteride’s DHT-reducing properties.
You can get topical finasteride and minoxidil from DrHair at the best price to maximise hair growth while minimising the risk of systemic side effects.
You can also find these formulas in a range of product types, including:
- Alcohol-based formulations
- Gel-based formulas
- Foam-based applications
Different types of topical finasteride applications may have specific benefits. For example, some people may find gel-based formulations produce less irritation than alcohol-based options, whereas if ease of use is the primary goal, you may prefer to go with a foam-based product.
How should I use topical finasteride products?
You should apply your finasteride and minoxidil formula at least once a day. Some products require twice-daily application, so check your prescription instructions carefully.
When applying the product, ensure your scalp is clean and dry. Avoid hairwashing soon after application, as this may interfere with the product’s absorption and efficacy.

FAQs
Oral finasteride enters your bloodstream and affects the level of DHT throughout your body. Topical finasteride is applied directly to your scalp. Therefore, it has a more localised and targeted effect on hair loss. Each treatment type has pros and cons, so seek expert advice to find the best solution for your needs.
Studies have shown that oral and topical finasteride products effectively reduce further hair loss and may even promote hair growth in some cases. One study showed that oral finasteride was about 20% more effective than topical products, but more evidence is needed.
Topical finasteride is associated with a different type of side effects. While some men experience issues with libido and sexual function on oral finasteride, the topical products do not produce these systemic effects. Instead, they may cause minor skin irritation or itching in some cases. Not everyone will experience side effects from either treatment, however.
Topical finasteride products are usually applied daily, but some formulations require twice daily application, so you’ll need to check your specific product instructions for best effects. If you have any concerns about how to use topical finasteride, please seek appropriate medical support.
