Hair loss affects millions of Australian men and can have a significant impact on confidence and self-esteem. If you've been researching treatments, you've probably come across topical finasteride as an alternative to the traditional oral tablet.
But does topical finasteride actually work? Is it available in Australia? And how does it compare with oral finasteride?
Here's everything you need to know.
What Is Topical Finasteride?
Topical finasteride is a medication applied directly to the scalp to treat androgenetic alopecia (male pattern hair loss).
Like oral finasteride, it works by blocking the enzyme 5-alpha reductase, which converts testosterone into dihydrotestosterone (DHT). DHT is the hormone primarily responsible for shrinking hair follicles in genetically susceptible individuals.
By reducing DHT levels in the scalp, topical finasteride aims to:
- Slow further hair loss
- Preserve existing hair
- Promote hair regrowth in some men
Unlike oral finasteride, the medication is delivered directly where it's needed.
Does Topical Finasteride Work?
Current evidence suggests that yes, topical finasteride can be effective.
Several clinical studies have shown that topical finasteride:
- Increases hair density
- Reduces hair shedding
- Produces improvements comparable to oral finasteride in many patients
Importantly, studies have also demonstrated that topical application reduces systemic absorption, meaning less of the medication reaches the bloodstream compared with taking a tablet.
However, while systemic exposure is lower, it is not zero.
Topical Finasteride vs Oral Finasteride
Topical Finasteride
Applied directly to the scalp
Lower systemic absorption
Reduces scalp DHT
May reduce risk of systemic side effects
Usually compounded in Australia
Oral Finasteride
Taken as a daily tablet
Higher systemic absorption
Reduces scalp and blood DHT
More evidence over 20+ years
Widely available
Both treatments aim to achieve the same goal—lowering DHT around hair follicles.
Does Topical Finasteride Have Fewer Side Effects?
This is one of the biggest reasons people choose topical finasteride.
Because less medication enters the bloodstream, topical finasteride may reduce the likelihood of systemic side effects such as:
- Reduced libido
- Erectile dysfunction
- Reduced ejaculate volume
However, it's important to understand that:
- Some medication is still absorbed.
- Side effects can still occur.
- Long-term data are more extensive for oral finasteride than topical formulations.
No treatment is completely free of risk, and decisions should always be made after discussing the benefits and risks with a doctor.
Is Topical Finasteride Better Than Oral Finasteride?
There isn't a single answer.
Some men prefer oral finasteride because:
- It's simple to take.
- It has decades of clinical evidence.
- It's usually less expensive.
Others prefer topical finasteride because they wish to minimise systemic exposure.
The "better" treatment depends on factors including:
- Severity of hair loss
- Previous response to treatment
- Personal preference
- Tolerance of potential side effects
Can Topical Finasteride Be Combined with Minoxidil?
Yes.
Many compounded topical products combine:
- Finasteride
- Minoxidil
This combination targets hair loss through two different mechanisms:
Finasteride
- Reduces DHT
Minoxidil
- Stimulates hair follicles and prolongs the growth phase of hair
Some studies suggest combination therapy produces greater improvements than either treatment alone.
Is Topical Finasteride Available in Australia?
Topical finasteride is not currently available as a standard commercial product in Australia.
Instead, it is commonly supplied by compounding pharmacies following assessment and prescription by a medical practitioner.
If clinically appropriate, you can also speak with an Australian-registered doctor via telehealth at NextClinic. Following a clinical assessment, the doctor may prescribe a compounded topical finasteride formulation if it is considered suitable for your individual circumstances.
The exact concentration and formulation may vary between pharmacies.
Who Might Consider Topical Finasteride?
Topical finasteride may be considered for men who:
- Have early male pattern hair loss
- Prefer not to take oral medication
- Experienced side effects with oral finasteride
- Wish to reduce systemic exposure while treating scalp DHT
It may not be appropriate for everyone, and a medical assessment is recommended before starting treatment.
How Long Does It Take to Work?
Hair growth takes time.
Most patients require 3 to 6 months before noticing reduced hair shedding or early regrowth.
Maximum benefit is often seen after 12 months of consistent treatment.
Stopping treatment usually results in gradual progression of hair loss over the following months.
Can Women Use Topical Finasteride?
Finasteride is generally not recommended during pregnancy or for women who may become pregnant, as it may affect the development of a male fetus.
Specialist advice should always be sought before considering finasteride in women.
Is topical finasteride available in Australia?
Yes. Topical finasteride is available in Australia with a prescription and is typically prepared by compounding pharmacies rather than being sold as a standard commercial product.
Does topical finasteride work?
Studies suggest topical finasteride can effectively reduce hair loss and improve hair density in men with androgenetic alopecia. Results usually become noticeable after 3–6 months of consistent use.
Is topical finasteride better than oral finasteride?
Neither is universally better. Oral finasteride has the longest track record, while topical finasteride may reduce systemic absorption and may be preferred by some men concerned about systemic side effects.
Does topical finasteride have side effects?
Yes. Although systemic absorption is generally lower than oral finasteride, side effects can still occur. Some people may also experience scalp irritation.
Can topical finasteride cause erectile dysfunction?
The risk appears to be lower than with oral finasteride due to reduced systemic absorption, but erectile dysfunction and other sexual side effects have still been reported.
Can I use topical finasteride with minoxidil?
Yes. Topical finasteride is commonly combined with topical minoxidil, and the combination may provide greater hair growth than either treatment alone.
How long does topical finasteride take to work?
Most people need to use topical finasteride consistently for at least 3–6 months before noticing improvements, with maximum benefits often seen after around 12 months.
Do I need a prescription for topical finasteride in Australia?
Yes. Topical finasteride is a prescription-only medication and should only be used under the guidance of a registered medical practitioner.
Is topical finasteride suitable for women?
Topical finasteride is generally not recommended for women who are pregnant or may become pregnant because of the potential risk to a male fetus. Specialist medical advice is recommended.
What happens if I stop using topical finasteride?
Hair loss will usually resume gradually after stopping treatment, and any benefits achieved are likely to diminish over time.
Can I get a topical finasteride prescription in Australia?
Yes. After an online consultation, practitioners on the NextClinic telehealth platform can assess your condition and, if clinically appropriate, prescribe compounded medications, including topical finasteride. As with all prescription medicines, treatment is only recommended when your doctor determines it is safe and suitable for your individual circumstances.
