Topical Finasteride for Hair Loss
HAIR LOSS TREATMENT
A targeted approach to reducing hair follicle sensitivity to DHT. Topical finasteride is a formulation designed to deliver finasteride directly to the scalp, where it can help reduce the effects of dihydrotestosterone (DHT) on susceptible hair follicles.

What is finasteride?
Finasteride is a medication that inhibits the enzyme 5-alpha-reductase. This enzyme converts testosterone into dihydrotestosterone (DHT), a hormone involved in androgenetic alopecia.
DHT is one of the main drivers of androgenetic alopecia (male pattern hair loss), contributing to progressive follicle miniaturisation and gradual thinning of the hair. Our topical finasteride formulations are prepared following a clinical assessment, allowing treatment options to be considered based on your individual circumstances, goals, and preferences.
THE SCIENCE
How does finasteride work?
By reducing DHT activity, finasteride may help slow this process and support maintenance of existing hair. Topical finasteride is applied directly to the scalp, and the aim is to:
Reduce DHT activity around the hair follicle
Target the scalp area affected by hair loss
Limit exposure compared with oral administration
Research suggests topical finasteride can reduce scalp DHT levels while producing less reduction in circulating DHT compared with oral finasteride. However, topical application can still result in some absorption into the bloodstream, meaning potential systemic effects should still be considered.
MAKING THE RIGHT CHOICE
Topical finasteride vs oral finasteride
Topical Finasteride
Topical finasteride for hair loss aims to provide a more scalp-focused approach.
More targeted delivery
The medication is applied directly to the scalp where treatment is required.
Lower systemic exposure
Studies suggest topical finasteride may result in lower reductions in blood DHT compared with oral finasteride, although absorption varies depending on formulation, dose, and application.
Option for patients concerned about oral therapy
Some patients prefer a topical approach due to concerns about systemic exposure or personal preference.
Flexible formulation options
Topical formulations can be adjusted depending on clinical considerations, including concentration, vehicle, and patient preference.
Oral Finasteride
Oral finasteride has been widely studied and is an established treatment option for male pattern hair loss.

-
Strong evidence base
-
Convenient once-daily dosing

Potential side effects and considerations
Topical vs oral risk: Topical application means lower systemic absorption than oral finasteride, so these effects — especially the sexual and mood-related ones — are generally less likely. They're not eliminated, though, so still worth discussing before starting.
Common (affects approximately 1 in 10 people)
-
Scalp irritation, dryness, or itching at the application site

Mild mood changes
Rare (affects approximately 1 in 1,000 people)
-
Erectile dysfunction
-

-
Breast tenderness or swelling (gynaecomastia)
-
Testicular discomfort
Very rare (affects approximately 1 in 10,000 people)
-
Persistent sexual side effects continuing after stopping treatment (post-finasteride syndrome)
-
Significant mood disorder, including reports of suicidal thoughts
-
Changes to semen parameters affecting fertility
How long does it take to work?
Hair growth is a slow process. Most hair-loss treatments require consistent use over several months before meaningful changes can be assessed. Some people notice reduced shedding before visible improvements in density.
Treatment response varies between individuals depending on:
-
Age
-
Extent of miniaturisation
-
Duration of hair loss
-
Genetics
-
Treatment adherence
Not suitable for women who are pregnant, breastfeeding, or of childbearing potential. May be considered for postmenopausal women following clinical consultation.
Frequently Asked Questions
Is topical finasteride safer than oral finasteride?
Topical finasteride may reduce systemic exposure compared with oral treatment, but it does not completely eliminate absorption into the bloodstream. Both options require consideration of individual risks and benefits.
Can topical finasteride regrow hair?
Finasteride primarily works by slowing DHT-related follicle miniaturisation. It may help maintain existing hair and, in some individuals, improve density where follicles are still viable.
Can topical finasteride be combined with minoxidil?
Combination treatment may be considered in some patients because the treatments work through different mechanisms. Suitability depends on individual assessment.
Do I need to use topical finasteride forever?
Finasteride needs to be used consistently to maintain its benefits. If treatment is stopped, any hair maintained or gained from treatment may gradually be lost over the following months.
