A little more scalp showing on top than you would like, and a hundred answers online. Does minoxidil actually work? Foam or liquid? 2% or 5%? Is all that shedding at the start normal? And do you really have to use it forever?

Here is where the experts land. Minoxidil is the hair loss treatment the experts reach for first, and they trust it to work, with decades of trials behind it. It is still a medicine, and it is meant for the slow, hereditary kind of thinning, so sudden or patchy hair loss is one for a doctor first. If you just want a name, the minoxidil product they rate highest right now is Rogaine Minoxidil 5% Foam, with a Guru Score of 86% from 18 experts.

Minoxidil itself has a Guru Score of 94%, and the praise is about results and evidence. The reservations are about living with it: the itchy scalp, the greasy feel, the early shedding, and the fact that it only works for as long as you keep using it. A growing number of the experts now talk about minoxidil tablets too, which are a prescription medicine. Below, what the experts said sits next to what the studies and the medicine labels say, so you can see where the two line up.

The quick answer

Minoxidil is a medicine for hereditary hair loss (male and female pattern hair loss) that helps regrow hair and slow thinning on the scalp. The experts we track rate it highly, and their doubts are about living with it rather than whether it works. On the scalp, as a foam or a liquid, it is sold without a prescription in the US and the UK [14, 19]. Results take months, and a US label says regrown hair is likely to be lost within three to four months of stopping [17]. Minoxidil tablets for hair loss are an off-label use of a prescription blood pressure medicine, so they need a doctor [1, 20, 21].

Before you buy

Before you start minoxidil

  1. Know your kind of hair lossIt is for hereditary thinning on the scalp. Sudden, patchy hair loss, or loss after childbirth, needs a doctor first [17].
  2. Try the foam if the liquid itchesThe liquid usually contains propylene glycol, a common cause of scalp reactions [12, 18]. Many experts prefer the foam.
  3. Give it months, then keep goingSome people need 4 to 6 months to see results [17, 18], and regrown hair is likely to go within three to four months of stopping [17].
  4. Not in pregnancy, and mind your petsThe labels say not to use it when pregnant or breastfeeding [17, 19]. It is toxic to cats and dogs, so let it dry and keep pets off your pillow [14].

Minoxidil at a glance

QuestionWhat we found
What is it used for?Hereditary hair loss on the scalp, in men and women [17, 18, 19].
Do skincare experts recommend it?Yes, warmly. Their doubts are about the itch, the greasy feel and sticking with it, not about whether it works.
Does it need a prescription?Not the foam or liquid, in the US or the UK [14, 19]. The tablets do [20, 21].
Foam or liquid?Many experts prefer the foam. The liquid usually contains propylene glycol, a common cause of scalp reactions [12, 18].
How long until it works?Results can show from 2 to 3 months, but some people need 4 to 6 months [17, 18].
What if you stop?Hair loss picks up again, and new hair is likely to go within three to four months [17].
Is it safe in pregnancy?No. The labels say not to use it when pregnant or breastfeeding [17, 19].

Minoxidil for hair loss: what does it do?

Minoxidil started life as a blood pressure tablet, and in that form it is still a prescription medicine for severe high blood pressure [20, 21]. Extra hair growth is one of its most common side effects at those doses [21]. Dr Dray, a dermatologist, explains that this side effect is how minoxidil was reworked into a treatment you put on your scalp.

On the scalp it is approved to regrow hair in hereditary hair loss, the slow thinning on the top of the head that runs in families [17, 18]. It comes as a liquid or a foam, at 2% or 5%. It is not meant for sudden, patchy hair loss, for hair loss after childbirth, or for hair loss without a known cause, so the labels say to see a doctor first in those cases [17].

Nobody is completely sure how it works. Dr. Mamina, a dermatologist, says it involves keeping hairs in their growth phase for longer and enlarging the follicle, and Dr Dray points to better blood flow to the follicle. It also helps to know it does not work for everyone. Dr Dray explains that minoxidil has to be switched on by an enzyme in the hair follicle, and some people simply have less of it.

The short versionMinoxidil is a hair regrowth medicine for hereditary thinning. The scalp version is sold over the counter; the tablets are a prescription drug.

Says the tablets can work better for some people than the topical, with the same early shed and more unwanted body and facial hair.
In a lot of cases you might even get more substantial or better results with Oral Minoxidil compared to the topical stuff, maybe because of differences in enzyme activity or just overall uptake into the hair follicle. [...] You can experience an increase in hair shedding in the first few months of starting Oral Minoxidil, same as with the topical. [...] With Oral Minoxidil, hypertrichosis, hair growth on the body and face, is a lot more common of a side effect. Watch ▸

Always recommends 5% over 2%, keeping 2% only for people who get side effects on 5%.
If someone is going to be using topical minoxidil I always recommend they use the 5%. There is 2% available over the counter but 5% is so much more effective. [...] In rare cases someone may have side effects from 5% minoxidil but be able to tolerate 2% minoxidil and that is essentially the only case where I would recommend that lower concentration.

Prefers the foam because the liquid's propylene glycol irritates, and warns that stopping sends hair back to where it started.
I prefer the foam over the solution. The solution can be quite drying and irritating to your scalp. It has propylene glycol, which they think is probably the culprit of irritation, dryness, and flaking. You want to stay with your medicine for as long as you can because if you stop your minoxidil [...] your hair is going to fall out and go back to baseline. Watch ▸

Moved to minoxidil tablets because the topical irritated her scalp, and calls the change one of the most impressive for her hair.
Since April I have been on Oral minoxidil [...] because I couldn't take the irritation from the topical one and it was making me look like I had dandruff, and honestly this has been one of the most impressive things that have changed the course of my hair. Watch ▸

Calls it no miracle cure but one of the most accessible, well-studied treatments, and gives it at least six months.
Minoxidil is not a miracle cure, but it is one of the most affordable, well-studied, and accessible treatments that we have for hair loss. The truth is it works for people when used consistently. If you notice thinning and if you still have active follicles, minoxidil can help support that regrowth and slow further loss. But it takes time. I usually recommend giving it at least 6 months before deciding whether it is working for you. Watch ▸

Points out that the hair falls out when you stop, and that a trial found rosemary oil itched less than minoxidil.
The thing is that when you stop using the minoxidil the hair falls out and here's the thing they compared minoxidil to rosemary oil and they found that people who used rosemary oil consistently actually had less irritation than the minoxidil group Watch ▸
Key takeawayThe experts trust minoxidil to work. Their advice is about the right strength and format, and about sticking with it.

Where do the experts agree?

The experts mostly agree that it works, so the caveats are where the useful detail sits.

Where they agree

  • It is the best-studied hair loss treatment you can buy without a prescription.
  • Choose 5%, whatever the box says about men or women.
  • If the liquid irritates, switch to the foam.
  • Give it at least six months, and keep going: stop and the hair goes.

The caveats

  • The evidence for 5% over 2% is clearer in men than in women [7, 8, 9].
  • Itching, irritation and an early shed are common [8, 19].
  • The tablets are a prescription medicine, used off label for hair loss [1, 20, 21].
  • Not for pregnancy or breastfeeding, and toxic to cats and dogs [14, 17, 19].

What does the research say about minoxidil?

Topical minoxidil has decades of trials behind it. In a 16 week trial in 352 men, 5% minoxidil foam raised hair counts significantly more than a placebo foam, and it was well tolerated over a year [11]. A Cochrane review of the treatments for female pattern hair loss found evidence for minoxidil's effectiveness and safety in women, though much of it was of moderate to low quality [9].

On strength, the picture differs between men and women. In a 48 week trial in 393 men, 5% beat 2% for hair regrowth [7]. In women, a 48 week trial found 5% better than 2% mainly in how the women themselves rated it, with more itching, irritation and unwanted hair on 5% [8], and the Cochrane review found no clear difference between the two strengths [9]. A once-daily 5% foam did as well as a twice-daily 2% liquid in women, with less itching and dandruff [10].

The tablet evidence is newer and growing fast. A review of 17 studies in 634 patients called low-dose oral minoxidil an effective and well-tolerated option for healthy people who struggle with the topical forms [2]. It is not clearly stronger, though: a 24 week trial in men found 5 mg tablets were not superior to 5% topical minoxidil overall [4], and a meta-analysis of four trials found no difference in hair density between the two [5].

The rosemary oil trial

Cassandra Bankson, a medical esthetician, points to a trial in which rosemary oil caused less itching than minoxidil. That trial is real: in 100 people over six months, rosemary oil and minoxidil raised hair counts by a similar amount, and scalp itching was more common with minoxidil [13]. The catch is that it used 2% minoxidil, and neither group had improved at three months [13]. Our rosemary oil guide has more.

The thing to rememberStrong evidence for topical minoxidil, clearest for 5% in men. Tablets look about as effective as the topical, not clearly better.

Topical vs oral minoxidil: which is better?

Several of our experts have moved to tablets, or prescribe them. Here is how the two compare.

Topical minoxidil

The foam and liquid are over the counter. In the US it has been sold without a prescription since 1996 [14], and in the UK the 5% foam for women is on general sale [19]. The downside is the routine: it goes on every day, and the effort of applying it, changes to hair texture and scalp irritation put some people off [2].

Oral minoxidil

Minoxidil tablets are a prescription medicine in the US and the UK, licensed only for severe high blood pressure [20, 21]. Using a low dose for hair loss is off label, and expert reviewers say there are no established best practices yet [1]. Dr Dray and Dr. Shereene Idriss, both dermatologists, describe it as an easier option for people who cannot get on with the topical. Dr. Daniel Sugai, also a dermatologist, says the trick is finding the patients who can tolerate a blood pressure medicine.

The commonest side effect is extra hair on the face and body. In 1,404 patients on low doses it affected 15.1%, with lightheadedness in 1.7%, fluid retention in 1.3% and a fast heartbeat in 0.9%, and 1.7% stopped because of side effects [3]. A meta-analysis found low doses did not significantly change blood pressure but did raise heart rate [6]. At full blood pressure doses, the US label carries a boxed warning about fluid around the heart and worsening chest pain [21], which is why the tablets need a doctor.

Is oral minoxidil stronger?

Some of our experts say so. Darnell Cox, a healthy-ageing creator, says the tablets work much better than the topical, and in one video calls slightly lower blood pressure the only side effect (elsewhere she mentions the extra peach fuzz too). The trials do not back either claim: in men, 5 mg tablets were not superior to the topical overall [4], and extra hair growth, not blood pressure, is the commonest side effect [3, 5]. Never change your own blood pressure medicine because of minoxidil; that is a conversation for your doctor.

If you remember one thingTopical first for most people. Tablets are a prescription option for those who cannot get on with the topical, not a stronger upgrade.

How do you use minoxidil?

Follow the directions on the pack. The US women's 5% foam goes on once a day [17], and the men's 5% liquid twice a day [18]. Apply it to a dry scalp in the thinning area, not to other parts of the body [17, 18].

Which strength?

Most of our experts say 5%, whatever your gender. Dr. Sam Ellis, a dermatologist, only suggests 2% for someone who gets side effects on 5%. The evidence favours 5% most clearly in men [7], and a once-daily 5% foam is sold for women in the US and the UK [17, 19]. The US men's liquid says on the pack that it is not for women [18], so women who want 5% will usually find the women's foam the straightforward choice.

Foam or liquid?

If the liquid makes your scalp itch or flake, try the foam. Dr. Daniel Sugai, Dr. Sam Ellis and Doctorly all point to propylene glycol in the liquid. In patch testing of people who reacted to minoxidil liquid, propylene glycol was the cause in most cases [12], and the foam was made without it [11]. Dr. Jenny Liu, a dermatologist, adds that the foam is less likely to run down your face.

The early shed

Many people shed more hair at the start. The UK label says a temporary increase in shedding usually begins two to six weeks after starting and settles within a couple of weeks [19]. Dr Dray describes the same thing with the tablets. It is a reason to keep going, not to stop.

How long to wait

The US men's liquid says results may show at 2 months, but some men need at least 4 [18]. The women's foam says 3 months, and at least 6 for some women [17]. Tea with MD, a dermatologist, gives it at least six months before deciding. If nothing has regrown by then, the labels say to stop and ask a doctor [17, 18].

Stopping

Minoxidil only works while you use it [22]. The US women's label says that if you stop, normal hair loss starts again and you will probably lose the regrown hair within three to four months [17]. Beyond50Skin, who used it for ten years, describes a heavy shed after she stopped, and went back on it.

Side effects to know

Itching, irritation and rash are the common ones, plus unwanted hair on the face, which can happen if it spreads beyond the scalp [8, 19]. Stop and see a doctor if you get chest pain, a racing heartbeat, faintness, dizziness, sudden weight gain or swollen hands or feet [17, 18].

Pets, especially cats

Topical minoxidil is dangerous to cats and dogs. In 211 poison centre cases, cats were mostly exposed by licking an owner's skin or pillowcase, signs appeared after only drops or licks, and 8 of the 62 cats that fell ill died [14]. Dr. Daniel Sugai and Tea with MD both warn about this. Apply it away from pets, wash your hands, let it dry fully and keep pets off your pillow.

Pregnancy and breastfeeding

Do not use minoxidil if you are pregnant or breastfeeding. The US labels say it may be harmful [17, 18], and the UK label says it should not be used in pregnancy or while breastfeeding [19]. The UK tablet label says the tablets are not recommended in pregnancy or for women who could become pregnant and are not using contraception [20]. Dr. Mamina, a dermatologist, notes the breastfeeding data are limited and says to decide with your doctor.

Worth knowingUse 5% as directed, try the foam if the liquid irritates, expect an early shed, and give it six months. Keep it away from pets and out of pregnancy.

What can you use minoxidil with?

Minoxidil is often one part of a hair loss plan rather than the whole of it.

Minoxidil and finasteride

This is the classic pairing for male pattern hair loss, and the NHS calls the two the main treatments for it [22]. A meta-analysis of five trials found the combination gave better results on photo assessments than either alone, with no more side effects [16]. Finasteride is a prescription medicine, and the NHS says women should not use it [22]. Our finasteride guide covers it.

Minoxidil and microneedling

Doctor Youn, a plastic surgeon, suggests rolling or stamping the scalp before applying minoxidil. In a pilot trial in 100 men, weekly microneedling plus minoxidil raised hair counts far more over 12 weeks than minoxidil alone [15]. It was a small study. Because the labels say not to use minoxidil on a red, inflamed or irritated scalp [17, 18], have microneedling done properly and ask when to restart.

Minoxidil and rosemary oil

We found no trial of the two used together. The one head-to-head trial compared rosemary oil with the weaker 2% minoxidil [13]. If you want to try rosemary oil, keep it as an extra rather than a swap: Beyond50Skin says her attempt to replace minoxidil with another system ended in a big shed.

Which minoxidil products do the gurus rate?

A high score for the ingredient does not carry over to every product that contains it. Strength and format change the verdict. These are the highest-scoring minoxidil products that at least two experts have rated, ranked by Guru Score.

Frequently asked questions about minoxidil

01

Does minoxidil really work for hair loss?

Yes, for hereditary hair loss in men and women, though not for everyone. In a trial in 352 men, 5% foam raised hair counts significantly more than a placebo [11], and a Cochrane review found evidence it works in women too [9]. Dr Dray notes some people do not respond because they have less of the follicle enzyme that switches it on. The experts we track rate it highly.

02

How long does minoxidil take to work?

Usually a few months. The US men's liquid says results may show at 2 months, but some men need 4 [18]. The women's foam says 3 months, or at least 6 for some women [17]. Tea with MD, a dermatologist, recommends at least six months before deciding. If nothing has regrown by then, the labels say to stop and see a doctor [17, 18].

03

Is shedding on minoxidil normal?

Yes, an early shed is common and temporary. The UK label says increased shedding usually starts two to six weeks after you begin and settles within a couple of weeks [19]. Dr Dray describes the same early shed with the tablets. Keep going unless you have other side effects, and see a doctor if the shedding carries on.

04

What happens if you stop using minoxidil?

The hair loss comes back. Minoxidil only works while you use it [22], and the US women's label says you will probably lose the regrown hair within three to four months of stopping [17]. Dr. Daniel Sugai, a dermatologist, says your hair goes back to baseline, and Beyond50Skin describes a heavy shed after she stopped.

05

Minoxidil 2% vs 5%: which should I use?

Most of the experts say 5%. In men, 5% regrew more hair than 2% in a 48 week trial [7]. In women the gap is smaller: one trial favoured 5% mainly in the women's own ratings [8], and a Cochrane review found no clear difference [9]. A once-daily 5% foam is sold for women in the US and UK [17, 19]. 5% can cause more itching and facial hair [8].

06

Minoxidil foam vs liquid: which is better?

Many experts prefer the foam, mainly because it is gentler. The liquid usually contains propylene glycol [18], which was the cause of most reactions in people patch tested after reacting to minoxidil liquid [12]. In women, a once-daily 5% foam worked as well as a twice-daily 2% liquid with less itching and dandruff [10]. Dr. Jenny Liu adds that the foam drips less.

07

Can women use minoxidil?

Yes. Topical minoxidil is approved for female pattern hair loss, and there is a once-daily 5% foam for women in the US and the UK [17, 19]. The US men's liquid says on the pack that it is not for women [18]. It is not for hair loss after childbirth, sudden patchy loss or loss without a known cause, so see a doctor first in those cases [17].

08

Is oral minoxidil better than topical?

Not clearly. A 24 week trial in men found 5 mg tablets were not superior to 5% topical minoxidil overall [4], and a meta-analysis of four trials found no difference in hair density [5]. Tablets suit people who cannot get on with the topical [2], and Dr. Shereene Idriss switched for that reason. They need a prescription and cause more body and facial hair [5, 21].

09

Does oral minoxidil affect your heart or blood pressure?

At low doses, usually only a little. A meta-analysis found low-dose tablets did not significantly change blood pressure but raised heart rate [6], and in 1,404 patients lightheadedness, fluid retention and a fast heartbeat were uncommon [3]. At blood pressure doses the label carries a boxed warning about fluid around the heart [21], which is why a doctor has to prescribe and monitor it.

10

Is minoxidil safe during pregnancy or breastfeeding?

No. The US labels say it may be harmful when pregnant or breastfeeding [17, 18], and the UK label says it should not be used in pregnancy or while breastfeeding [19]. The UK tablet label also advises against it in women who could become pregnant and are not using contraception [20]. Ask your doctor about safer options.

11

Is minoxidil dangerous for cats and dogs?

Yes, especially for cats. In 211 poison centre cases, most cats were exposed by licking their owner's skin or pillowcase, illness followed even drops or licks, and 8 of the 62 cats that fell ill died [14]. Apply it away from pets, wash your hands, let it dry fully and keep pets off your bed and pillow.

12

Can you use minoxidil with finasteride?

Yes, and it is a common pairing for male pattern hair loss. A meta-analysis of five trials found the combination did better on photo assessments than either drug alone, with no rise in side effects [16]. Finasteride needs a prescription, and the NHS says women should not use it [22]. Our finasteride guide has the details.

13

Does microneedling help minoxidil work?

Possibly. In a pilot trial in 100 men, weekly microneedling plus minoxidil raised hair counts far more over 12 weeks than minoxidil alone [15]. It was one small study. Doctor Youn, a plastic surgeon, suggests it, but the labels say not to use minoxidil on a red, inflamed or irritated scalp [17, 18], so ask when to restart after a session.
