A hair loss routine is often presented as a list: a foam, a tablet, a roller, three supplements and a shampoo, all started at once. The research we reviewed does not support adding everything. A routine is a small number of things you can keep using for months, each one there for a reason.
This page sorts the common pairings by what the research shows: what has been studied together, what are two versions of the same thing, what is optional, and what the studies we reviewed do not show to add anything as a pair. It is written for adult men with male pattern hair loss, the gradual thinning at the hairline or the crown. Sudden shedding, patches or a sore scalp are a different situation, and the types of hair loss and when to get assessed first come before any routine.

What a routine is, and what it is not
A routine is not the top of our ranking added together. Minoxidil on the scalp and finasteride tablets are the two options to weigh first, and each of them can be a whole routine on its own. Adding a second thing is optional. Adding nothing is a valid outcome too. [1, 2]
Almost every pairing people ask about falls into one of four kinds.
Four kinds of relationship between two options
- Alternatives
- One or the otherTwo forms of one medicine, or two medicines of the same group. They do the same job, so one is chosen.
- Studied together
- A possible pairTrial evidence favours using the two together over either one alone. One pairing reaches this, with limits.
- Optional additions
- Assessed separatelyProcedures and devices. Each one is judged as a specific protocol, not as a category.
- Not established
- No added benefit shownEach part may have evidence of its own. The studies we reviewed do not establish an added benefit from using them together.
These are descriptions of the evidence we reviewed, not scores. They do not add up to a number.
What goes with what, at a glance
Each row below is a separate question with its own evidence. The sections that follow give the numbers and the limits. [3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17]

Not establishedEach was studied alone, as a specific preparation. Their separate results cannot be added up.
Not established means the studies we reviewed do not show an added benefit. It does not mean that no study exists, or that the pair is known to be harmful.
Options to choose between, not to stack
Minoxidil foam or solution
Foam and solution are two ways of putting the same medicine on the scalp. Each was tested against its own inactive version: the foam in 352 men over 16 weeks, the solution in 393 men over 48 weeks. Those trials do not show which form regrows more hair. One 2026 report compared the two directly in about 100 men over 12 weeks, but its numbers are inconsistent and we do not rely on it. The other direct comparisons were done in women, with 5% foam once a day against 2% solution twice a day, so they do not settle it for men either. [6, 1, 18, 19, 20]
The choice is a practical one: how your scalp tolerates each base, how it sits in your hair, and price. The minoxidil profile compares the forms in detail.
Finasteride or dutasteride
Both are prescription medicines of the same group, and trials have compared one with the other. In a trial that assigned 917 men to five groups, total hair count in the measured area rose by 89.6 hairs with dutasteride 0.5 mg (184 men) and by 56.5 with finasteride 1 mg (179 men) after 24 weeks. When only the thicker hairs were counted, dutasteride was not shown to be better. The trial was funded by GSK. [7]
Nothing here supports taking the two together. The UK finasteride label excludes combining it with another medicine of its group, and no source we reviewed tests a schedule for switching between them. Dutasteride is an alternative to discuss with a prescriber. It has no hair-loss label in the US or UK, and it stays in the body for months. [4, 23, 24]
Finasteride and dutasteride, side by side
Each column is the form its position in our ranking is based on: the 1 mg tablet and the 0.5 mg capsule.
| Criterion | No. 2FinasterideOral tablet | No. 3DutasterideOral capsule |
|---|---|---|
| Benefit shown | Benefit shown against placebo | Greater total hair-count gain than finasteride in one trial |
| Evidence | Broader clinical support | Limited support |
| Main risk | Sexual and psychiatric warnings | Systemic warnings; stays in the body for a long time |
| Routine | One tablet a day, on prescription | One capsule a day; long persistence matters |
| Time point | Three months or more before benefit | Compared at 24 weeks |
| If you stop | Benefit lasts only with continued use | Data during use; not established after stopping |
| Access | Tablet approved (US and UK checked); spray varies | Hair-loss approval varies by country |
| Cost | Depends on country and provider | Only one local price observed |
Two alternatives from the same group of medicines. The table is there to support a conversation with a prescriber, not to suggest taking both.
Two routes for the same medicine
The same holds when one medicine comes in two routes. Minoxidil by mouth was tested against the solution, as alternatives: in 90 men over 24 weeks, 5 mg a day by mouth did not beat the 5% solution on the trial's main measure. Whether tablets add anything on top of a scalp product has not been shown in the studies we reviewed. Nor does anything we reviewed test the finasteride tablet and scalp spray together. [14, 25]
Finasteride tablets with minoxidil on the scalp
This is the pairing with the most direct support: a large trial that set the pair against each of its parts. It randomly assigned 450 Chinese men to finasteride tablets, to 5% minoxidil on the scalp, or to both. After 12 months, 428 of them were assessed. [3] The page on minoxidil and finasteride together goes through this trial and the smaller studies around it.
Men rated as improved after 12 months
Finasteride tablets with minoxidil on the scalp152 men assessed
94.1%% of men
Finasteride tablets alone154 men assessed
80.5%% of men
Minoxidil on the scalp alone122 men assessed
59%% of men
Share of men rated as improved in the study, not the amount of hair gained. We could read only the published summary. It does not define the scale used, say whether the assessors knew who was on which treatment, give the amount of minoxidil applied or how often, or name a funder. [3]
More men improved with both. The figure counts men, so 94.1% is not 94.1% more hair, and it is not one person's chance of success. The chart also shows a gap between the two medicines used alone. We do not read it as a ranking: only the summary was available, and our review does not establish which of the two works better.
A second, much smaller study looked at the pair from the other side. Twenty-two men who were already taking finasteride every day were given a minoxidil lotion or the same lotion without minoxidil. The lotion had a limited extra effect, and staying on finasteride did not keep all of it once the lotion was stopped. The lotion was applied once a day in that study. That is the trial's own protocol, not what the men's labels say. [26]
What these studies do not show
- How much more hair the pair gives. The main trial reports shares of men, not hair counts.
- That the two multiply each other's effect. Doing better than either one alone is not proof of that, and neither study was designed to test it.
- How safe the pair is. The summary gives no usable side-effect figures for the men who used both. Each medicine keeps its own risks.
- That foam does the same. Foam was not a verified arm of these studies.
- That other pairings work. The result does not carry over to both medicines applied to the scalp, or to both taken as tablets.
What the labels say about using both
Published research and product labels are two different kinds of information, and both belong on the page. The UK finasteride tablet label states that no data are available on using it together with minoxidil on the scalp, and no label we checked describes a combined schedule. So each part keeps its own instructions: one 1 mg tablet a day for finasteride, and the amount and frequency printed on the minoxidil product you have. No best order, and no required gap between the tablet and the scalp application, has been established. [4, 2, 5, 21]
Combinations that are not established
For the pairings below, the studies we reviewed do not establish a dependable added benefit. For scalp mixes the results are mixed: some preparations did better on some measures and not on others. In several cases a study exists, but it could not answer the question or we could not read it in full.
Finasteride and minoxidil both on the scalp
Small trials have put the two medicines on the scalp together, as one mixed solution or as two products. Their results do not agree. [10, 11, 29, 30, 31]
| Trial | What was compared | Result against minoxidil alone |
|---|---|---|
| 42 men, 6 months | A finasteride spray in the evening and a minoxidil lotion in the morning, against the lotion twice a day | Photographs favoured the pair. Hair density did not rise significantly more. |
| 60 men, 24 weeks | One solution with finasteride 0.25% and minoxidil 5%, against minoxidil 5% | An advantage in some parts of the scalp and for some kinds of hair, not in others. |
| 40 men, 24 weeks | Finasteride 0.25% mixed with minoxidil 3%, against minoxidil 3% | The summary reports better density, hair thickness and photographs. The size of the difference was not available to us. |
| 40 men, 24 weeks | Finasteride 0.1% with minoxidil 3%, against minoxidil 3% | No significant difference in hair count. Photographs favoured the mix. |
| 40 men, 12 weeks | Finasteride 0.1% with minoxidil 5%, against minoxidil 5% | No difference between the groups in the growth measures. |
A trial that finds no significant difference has not proved that the mix adds nothing, and a favourable result belongs to the preparation that was tested. Strength, liquid base, volume and frequency change from trial to trial. They do not establish a best strength, an order of application or a gap between two products. Funding was declared as none in the 60-man trial. The 12-week trial was supported by a research grant from L'Oréal, PERDOSKI and Universitas Indonesia, declared to have had no role in the study. For the other three it was not identified in what we could read.
Finasteride and minoxidil both as tablets
A UK service looked back at men who had taken a single tablet combining minoxidil 2.5 mg and finasteride 1 mg for about a year. [13]
- Men in the report
- 502Selected because they had stayed on the tablet and had complete photos.
- Rated stable or improved
- 464On photographs, after about 12 months.
- Comparison group
- NoneSo it cannot show what the pair adds to either medicine alone.
Side effects were not recorded in a structured way, so the report says nothing reliable about safety. All of its authors work for the service. [13]
Botanicals with a medicine, or with each other
Where a botanical met a medicine in a trial, it was as a rival: saw palmetto against finasteride, a rosemary lotion against 2% minoxidil. Nothing we reviewed tests saw palmetto, rosemary or pumpkin seed oil on its own added to minoxidil or finasteride, and the safety of taking saw palmetto with finasteride or dutasteride has not been established. [16, 17, 33]
The closest thing is a trial of one supplement formula. It gave 225 people, 165 of them men, a hair-loss medicine, which differed from person to person, with or without a daily capsule of saw palmetto, pumpkin seed, cystine, vitamin C and zinc. After six months, 39 of 106 people on the formula reached a score of +3 on the trial's photographic scale, against 29 of 119 without it. Hairs were not counted, the treatments underneath were mixed, there was no placebo, and two of the authors work for the company that sells the formula. The result belongs to the whole formula. [15]
Nothing we reviewed tests saw palmetto, rosemary and pumpkin seed oil together either. A preference for botanicals leads to comparing preparations and choosing one, with its weaker evidence in view. It does not turn three of them into a proven stack. The profiles for saw palmetto, rosemary and pumpkin seed oil describe what each trial actually tested.
Where microneedling and devices sit
Microneedling, light devices and PRP are not ingredients, so they are not in our ranking. PRP is a procedure in which a preparation from the person's own blood is administered into the scalp. All three are optional, and each has to be judged as a specific protocol. They are listed separately in the library.
Microneedling added to minoxidil
Three small trials in men added microneedling to 5% minoxidil used twice a day, and all three recorded more regrowth than with minoxidil alone. All three also have reporting problems. In the first, the size of the counted area is described inconsistently, there was no sham procedure, and all six men who dropped out were in the minoxidil-only group. In the second, the paper gives three slightly different values for the same gain, and the eight men who dropped out were left out of the analysis. In the third, the paper gives two different figures for the same result, and the two groups differed in age. So we report the direction and not a number. The microneedling page goes through each trial in turn. [8, 38, 9]
Three microneedling trials, three protocols
What each study did. No column is a guide for use at home.
| In the trial | 2013First trial100 men, 12 weeks | 2018Second trial68 men, 12 weeks | 2024Third trial36 men, 12 weeks |
|---|---|---|---|
| Assessed | 94 men: 50 with microneedling, 44 without | 60 men: 31 with microneedling, 29 without | All 36: 18 in each group |
| Minoxidil | 5% lotion, 1 mL twice a day | 5% solution, 1 mL twice a day | 5%, twice a day. The amount was not reported in what we read |
| Needling | A 1.5 mm roller, once a week | A 1.5 mm roller: four weekly sessions, then four more two weeks apart | 0.6 mm, at weeks 0, 4 and 8 |
| Around a session | Minoxidil left out that day and restarted 24 hours later | Minoxidil left out that day and restarted 24 hours later | Minoxidil applied 24 hours after the session |
| Funding | Declared as none | Declared as none | A university grant |
Each column is that trial's own protocol, carried out as part of the study. The third trial also used an anaesthetic and fusidic acid. No study we reviewed establishes a best depth, interval or timing for minoxidil. Where the form is stated, the trials used a minoxidil lotion or solution. They do not show the same for foam. [8, 38, 9]
The result is not guaranteed to repeat either. A trial in 245 women, part-funded by a company, used 2% minoxidil with or without microneedling every two or four weeks and found no significant difference in the count of all hairs except the finest after 24 weeks. It was in women and we read only its summary, so it does not cancel the results in men. [39]
Light devices and PRP
Light devices and PRP are assessed the same way, one identified device or one defined course at a time, and this page does not go through their trials. One is directly relevant to a routine. It compared a light device with 5% minoxidil in 91 men, 75 of whom completed six months, and found no significant difference between the groups. That tests one against the other, not the two together, and it does not prove they are equal. We read only the summary, which does not say who funded the trial. [40]
What a device or procedure does on its own and what it adds to a medicine already in use are separate questions. If you are offered one, the useful first step is to pin down exactly what is being proposed.
Microneedling
- What to pin down
- The device, the depth, the interval, which minoxidil product is used, and what happens to it before and after each session.
Light devices
- What to pin down
- The exact model and its own instructions. Session times for one device do not carry over to another.
PRP
- What to pin down
- How it is prepared, how many sessions are planned, what they cost and how the result will be reviewed.
Choosing one of these is not a reason to choose all three.
Reference use: what the labels say
The amounts and timings in a routine come from the product you have. They do not come from a trial, and they do not come from another product. These are the men's labels we checked at the end of September 2026. [5, 6, 21, 22, 2, 4]
Reference use for the two core options
Minoxidil on the scalp and finasteride tablets, as their US and UK labels state it.
| On the label | UKRegaine for Men Extra Strength5% minoxidil solution | UKRegaine for Men Extra Strength5% minoxidil foam | USTwo men's 5% minoxidil productsA solution and a foam | US and UKPropecia1 mg finasteride tablets |
|---|---|---|---|---|
| For | Men aged 18 to 65 | Men aged 18 to 49 | Men 18 and over, top of the scalp | Men with male pattern hair loss, on prescription |
| Amount | 1 mL over all thinning areas | 1 g, about half a capful | 1 mL of solution, or half a capful of foam | One 1 mg tablet |
| How often | Twice a day, 2 mL a day at most | Twice a day, 2 g a day at most | Twice a day | Once a day, with or without food |
| First signs | After about 2 months | After about 8 weeks | After about 2 months; some men need at least 4 | US label: three months or more. UK label: generally three to six months before hair loss is seen to steady |
| No change? | Stop after one year | Stop at 16 weeks | Stop and see a doctor at 4 months | No fixed stopping point on either label. The UK label leaves the review to the prescriber |
Each column is a product's own label. Amounts and review points do not transfer from one product to another. The two US minoxidil labels are for the top of the scalp and are not intended for a receding hairline.
The hairline wording on the two US labels is taken up on the page about minoxidil and a receding hairline.
Dutasteride has no hair-loss label in the US or UK, and for the botanicals there is no medicine label to refer to. What exists for them is the way each trial used its own preparation, which the profiles describe. Those are records of what was tested, in the people chosen for that trial. They are not doses to follow, and they do not carry over to another product with the same ingredient on the label. [23, 24, 7, 41, 42, 17, 33]
Details that change how a routine is used
- The minoxidil amount is the total. One millilitre, or half a capful, covers all the thinning areas together. It is not an amount per area, and going over it does not improve the result.
- Healthy scalp only. The minoxidil labels do not cover use on irritated or damaged skin.
- Warning symptoms do not wait for a review point. The US minoxidil labels say to stop and ask a doctor about chest pain, a rapid heartbeat, faintness or dizziness, sudden unexplained weight gain, or swollen hands or feet. For finasteride 1 mg, the UK regulator's advice is to stop and contact a healthcare professional promptly if depression or suicidal thoughts develop. The minoxidil warnings are covered on the page about minoxidil side effects.
- Your country decides the leaflet. Other countries have their own products and instructions.
Five reference routines, as examples
These are the five patterns we use to show how the options fit together. They are educational examples, not a personal prescription, and none of them is a timetable. Where an amount applies, it is the label or the trial named in the tables above.
One minoxidil product on the scalp
- Review
- The point set by that label: 16 weeks, 4 months or one year.
Prescribed finasteride with one minoxidil product
- Review
- With the prescriber for the tablet. The minoxidil label keeps its own review point.
A medicine alternative, compared and not layered
- Not included
- A starting dose, an overlap period or a switching schedule. The sources do not establish one.
One botanical preparation, not a bundle
- Useful habit
- A list of every product you take and how much, to check for overlap.
An optional procedure or device
- Not included
- A needle depth, a number of sessions or a maintenance schedule.
A prescribed finasteride tablet on its own is also a complete routine: the second pattern without the minoxidil. Wanting fewer steps is a good enough reason to stay with one thing. If you would rather be pointed to the relevant part of the site, take the hair questionnaire. It does not diagnose hair loss or prescribe anything.
How long to give a routine, and how to keep track
Think in months, and let the product set the date. The labels expect first signs after about two months for minoxidil and three months or more for finasteride. Each minoxidil label then sets its own point to stop and get advice if nothing has changed. With two things in a routine, each keeps its own clock. [5, 6, 21, 22, 2]

A review point is the label's instruction to stop and get advice if there has been no improvement. A trial time point is when researchers measured, not a promise of when you will see a change. [5, 6, 21, 22, 2, 3]
The botanical trials measured at points between 16 weeks and 24 months. Those are the moments the researchers chose to look, not deadlines. And none of these dates applies to a side effect: a symptom that worries you is a reason to ask straight away. [42, 33, 41, 17, 16]
If one part is stopped
The gains depend on continued use. The minoxidil labels say regrowth lasts only while you keep applying it, and the UK solution label reports it fading within three to four months of stopping. The US finasteride label says the effect reverses within 12 months. In the small study of men using both, staying on finasteride did not keep everything the lotion had added once the lotion was stopped. These sources do not give a schedule for taking breaks or for coming off one part of a routine. [5, 21, 2, 26]
Keeping a record

Day-to-day change is too small to see in a mirror, and with two things in a routine it is easy to lose track of what you actually used. Three habits make a review point meaningful. They are organising suggestions of ours, not something tested in a trial:
- Photos. The same areas, in the same light, at the same hair length and from the same angle. At an interval you can keep up, once a month for example. We found no study showing that one interval is best.
- What you actually used. The exact product, the date you started each part and the days you missed. If a second thing is added later, its start date goes in too.
- Anything you notice. A scalp reaction, a change in mood or sexual function, or anything else new, with the date.
Photos are a record, not a test. They do not show the cause of hair loss, and on their own they do not decide whether a treatment should change.
Where to go next
For the procedure side of a routine, compare microneedling, light therapy and PRP. For recording what changes over time, use the hair tracking guide.
If you have not chosen a first option yet, start with the comparison and come back to combinations later. The ranking puts the three medicines side by side on the same eight criteria, and the methodology page explains how those criteria are applied.
