You've been using minoxidil for a while, or you're considering starting finasteride, and then you read somewhere that most dermatologists nowadays prescribe both simultaneously. Sounds logical. Two remedies that tackle hair loss from different angles, so why not use both?
However, it's not as simple as adding them up. In this article, you'll read what the combination actually yields according to research, when it's a logical step, and what you need to consider before starting.
Two remedies that do something different
Minoxidil and finasteride intervene at different points in the process. Minoxidil widens the blood vessels around the hair follicle and extends the hair's growth phase. It doesn't address the cause of hereditary hair loss but ensures that follicles that are still active can grow longer and stronger.
Finasteride does something different. It inhibits the conversion of testosterone to DHT, the hormone that causes follicles in men with a genetic predisposition to slowly shrink. So, while minoxidil primarily stimulates growth, finasteride slows down degradation.
Because the two remedies work through different mechanisms, they don't exclude each other. That's why doctors more often prescribe them together than one of the two alone.
What research says about the combination
Quite a bit of research has been done on the difference between the combination and one of the remedies alone. A 2020 meta-analysis that combined multiple randomized studies showed that the combination group scored better on the overall assessment of hair growth than the group using only minoxidil or only finasteride. More participants showed clear improvement, and fewer participants deteriorated.
A more recent 2025 analysis, based on seven randomized studies with nearly four hundred participants, came to a similar conclusion. The combination of minoxidil and finasteride scored better on hair density, hair thickness, and photographic assessment than minoxidil alone. The difference was most clearly visible in men who were rated as "clearly improved."
The outcome varies from person to person, but in multiple independent studies, the combination consistently performed better than either of the two remedies alone.
Is the combination a logical step for you?
That depends on where you currently stand. If you're still early in the process, with a slightly higher hairline or a bit more hair in the shower, then the combination of two medications is probably a bigger step than necessary. At that point, a serum or one of the two remedies can often achieve enough, without immediately taking on the full package of side effects and obligations.
If hair loss is already more visible, with a clearly receding hairline or a thinning crown, then the combination is more worth considering. Especially at that stage, the difference between "staying stable" and "further deteriorating" is greatest, and that's where the combination helps the most.
Always discuss this with a general practitioner or dermatologist before you start. Finasteride is only available by prescription in the Netherlands, and for good reason. A doctor can assess whether the combination is useful in your situation and point out signals that mean you should stop.
How to incorporate it into your routine
In practice, you take finasteride as a tablet, usually once a day, and minoxidil as a lotion or foam that you apply to the scalp twice a day. They work through different channels in your body, so a fixed sequence between the two is not necessary. A few points to consider:
- Don't start both remedies on the exact same day. Start with the remedy your doctor prefers, and only add the second one after a few weeks.
- Don't apply minoxidil just before or after taking the finasteride tablet out of habit. There's no medical reason for this, but it helps keep the routine simple.
- If you notice skin irritation or another signal after adding the second remedy, you'll know better which remedy is the cause instead of having to guess.
Do the side effects add up?
The combination does not present a demonstrably higher risk than the sum of the two separate remedies, but the two side effect profiles are different:
- Minoxidil: local irritation or itching on the scalp, and a shedding phase in the first few weeks where you actually lose more hair.
- Finasteride: in a small percentage of users, an effect on libido or erection, and since 2025 officially linked to mood disorders as a recognized side effect.
These two profiles stem from different mechanisms, and there is no indication that they amplify each other.
What you should consider: because you are using two remedies at once, it becomes harder to trace which remedy is responsible if something changes in your skin, mood, or libido. That's why it's smart not to start on the same day, and why follow-up with your doctor is more valuable here than with just one remedy.
What if you're not ready for two medications yet?
Not everyone who sees their hairline changing is ready for a prescription and a daily application routine. For men who are still early in the process or prefer to try something without hormonal action first, the Hairborn Growth Serum is a logical first step. It contains Redensyl and caffeine, supports the scalp and hair follicle, and does not require a prescription or consultation with a doctor.
If you want to improve the absorption of active ingredients, a derma roller can help by creating small channels in the skin. This applies to a serum, but also to minoxidil, as long as you time its use carefully with other products.
If you want to know more about when a serum is enough and when medication offers added value, you can read about it in serum or medication for early hair loss. If you are specifically unsure about finasteride or minoxidil separately, you will find an honest overview in our articles on finasteride and minoxidil.
How much time do you give the combination?
Expect at least three to four months before you see any difference, and six months to a year for an honest assessment of the result. This is no different than with either of the two remedies alone, but it often feels heavier because you're maintaining two routines simultaneously without seeing anything yet.
Take a few photos beforehand from the same angle and in the same light. Without a fixed reference point, it's almost impossible to honestly assess slow changes, and this is even more true with a combination of two remedies than with one.
What you take away from this
The combination of minoxidil and finasteride scores better in multiple studies than either remedy alone. This is not a reason to simply start if you are still early in the process, but it is a reason to seriously discuss it with a doctor if your hair loss is already visible and you notice that one remedy is not enough.
If you prefer to start small and without a prescription, a serum is a sensible starting point. If you are further along and considering medication, take the time for a good conversation with your general practitioner before deciding which remedy, or which combination, suits your situation.
Frequently Asked Questions
What happens if you start both remedies on the same day?
This is not recommended because you won't be able to trace which remedy is causing any irritation or other complaints. Start with the remedy your doctor prefers and only add the second one after a few weeks, so you can clearly see what effect each one has.
Is the shedding phase more severe when using minoxidil and finasteride simultaneously?
There is no research suggesting a heavier shedding phase due to the combination. Shedding is a reaction to minoxidil, not finasteride, so adding finasteride generally doesn't change that. The timing and intensity vary greatly per person.
Can you use the combination if you don't have visible bald spots yet?
It's possible, but often not necessary. For men who are still early in the process, with only a slightly higher hairline or somewhat thinner hair, one remedy or a serum is usually sufficient. The combination becomes particularly useful as hair loss progresses.
Is there an all-in-one product with minoxidil and finasteride together?
In some countries, combination solutions are available, for example, a lotion containing both active ingredients. In the Netherlands, you usually receive two separate products prescribed by a general practitioner or dermatologist: a tablet and a lotion or foam.
What happens if you stop finasteride but continue with minoxidil?
The protection against DHT then disappears, allowing the underlying cause of hereditary hair loss to regain full sway. Minoxidil can still support the growth phase of the hair, but it does not fully compensate for what finasteride did.
Is the combination useful if minoxidil alone already works well?
If you are satisfied with the results of minoxidil alone and there's no deeper DHT sensitivity involved, there's not automatically a reason to add finasteride. Discuss with a doctor whether your type of hair loss would benefit from the extra step.
Can you add a derma roller to the combination?
Yes, you can, as long as you time it correctly. Do not use the roller just before applying minoxidil to irritated scalp, and allow sufficient time between rolling and applying products, usually around ten hours.
Is the combination covered by health insurance?
No, both finasteride and minoxidil for hair loss are not covered by reimbursed healthcare in the Netherlands because it concerns a cosmetic indication. The costs of prescriptions, medication, and any follow-up appointments are at your own expense.
Do I need to have blood values checked if I use the combination?
Standard blood tests are not mandatory for this combination, but a doctor may recommend it if you are taking other medications or have a medical history that requires it. Discuss this during the intake, so you know what to look out for.
Is the combination also suitable for men over fifty?
Age itself is not a reason to discourage the combination, but older men more often have other medications or health issues that a doctor needs to consider. An individual discussion is more important here than a general age limit.
