Rosemary oil or minoxidil? 6 differences in evidence, speed and price

Rosemary oil or minoxidil against hair loss? The short answer: minoxidil is a medicine that works against hereditary hair loss and the effect of which can become visible after about 2 to 4 months^[1]. So far, there is mainly a small study from 2015 for rosemary oil, in which 100 people with hereditary hair loss used rosemary oil or minoxidil 2% for 6 months^[2]. That study is interesting, but has clear limitations. If you want a treatment with the most evidence, then minoxidil 5% is the more logical choice. Rosemary oil is primarily a cosmetic alternative for those who want to try it and know that the evidence is still thin. Below we list the 6 most important differences.

Does rosemary oil work against hair loss?

Rosemary oil has become popular in recent years via TikTok and Instagram, where it is presented as a natural way to grow hair faster and fuller. Radar (AVROTROS) had these claims tested by doctor and researcher Hans van Montfort^[3]. His conclusion in short:

• Rosemary has anti-inflammatory and antioxidant properties. Because mild inflammation and oxidation often play a role in hair loss, an effect is theoretically conceivable.
• According to him, an effect has only been demonstrated in alopecia areata (patchy hair loss). There are indications for other forms, but no scientific evidence yet.
• Many products contain little active substance. The oil must be applied daily and left on for at least half an hour, and can make the hair greasy.

A recent review in Skin Appendage Disorders (2025) is more positive and mentions rosemary oil as a possible natural alternative, but also writes that more research is needed on dosage and application, and that many herbal studies are small and short^[4].

What does the research say about rosemary oil vs minoxidil?

Almost every claim that rosemary oil works "as well as minoxidil" is true back to one randomized study by Panahi and colleagues, published in 2015 in the journal Skinmed^[2]. This is what happened:

• 100 people with hereditary hair loss (androgenetic alopecia) were given rosemary oil (50) or minoxidil 2% (50).
• After 3 months, the number of hairs had not changed significantly in either group.
• After 6 months, the number of hairs had increased in both groups, with no significant difference between the groups.
• Itching on the scalp occurred in both groups, but more often in the minoxidil group.

Sounds good, but science writer Michelle Wong (Lab Muffin Beauty Science) listed a number of comments in 2024^[5]:

• Weak comparison: it was compared with minoxidil 2%, while for men usually 5% is used.
• No placebo group: without a group that did not receive anything active, it is impossible to say how much of the effect was due to the oil and how much was due to, for example, massaging or the season.
• Small and striking figures: the reported increase was small and some values in the tables appear to be errors contain.
• Unclear oil: it is not well described which type and dilution exactly was used, so you cannot simply copy it at home.

In short: the study is an indication, not proof that rosemary oil can replace minoxidil.

What are the 6 differences between rosemary oil and minoxidil?

1. Type of product

Minoxidil is a medicine that you can buy without a prescription, intended for hair loss according to the male or female pattern^[1]. Rosemary oil is a cosmetic oil. There is no fixed composition or concentration, so two bottles can be very different.

2. How much evidence there is

For minoxidil, the official product information states how often you use it, who it is intended for and when you can expect results^[6]. For rosemary oil there is one small study without placebo^[2].

3. How quickly you see something

With minoxidil 5%, according to the product information, you can see the first growth after 2 months or more^[6]; Apotheek.nl mentions about 4 months, with the maximum effect after about a year^[1]. In the rosemary study there was no difference after 3 months and only after 6 months^[2]. Want to know more about what you can expect per month? Read our timeline of minoxidil results.

4. Ease of use

Minoxidil 5% for men is applied twice a day, 1 ml each time, and no more than 2 ml per day^[6]. It is absorbed and you don't have to rinse it out. Rosemary oil has no fixed dosage, must be left in for at least half an hour according to Van Montfort and can make the hair greasy^[3].

5. Side effects and safety

Minoxidil can cause headaches, itching, dry skin or unwanted hair growth in other places, and sometimes temporarily more hair loss^[1]in the first weeks. Do not use it during pregnancy, and in case of cardiovascular disease only in consultation with your doctor^[1]. The 5% lotion for men is intended for 18 to 65 years^[6]. Rosemary oil seems mild, but essential oil contains substances that can irritate the skin or cause an allergy^[5].

6. Price per month

A bottle of rosemary oil seems cheaper, but price and concentration vary greatly per brand. Minoxidil 5% costs at Minodeals from € 18.33 per month with a 6-month package of Kirkland Lotion (€ 109.99). You can read how Kirkland compares to Regaine in Kirkland or Regaine?

Which one suits you: rosemary oil or minoxidil?

Choose minoxidil if you have hereditary hair loss (inlets, thinning crown or a wider parting) and want a treatment that is known how you use it and when you can expect results. It works best for men under 40 with limited hair loss^[1]. Keep in mind that you continue to use it: after stopping, the new growth will disappear within 3 to 4 months^[1].

Choose rosemary oil if you prefer a cosmetic product, cannot or do not want to use minoxidil, and accept that the evidence is limited. Then don't expect the same as from a medicine.

Can you combine rosemary oil and minoxidil?

No research has been done on this. Apotheek.nl advises not to use other skin products, such as creams, on the scalp without first consulting your doctor^[1]. If you want to try both, consult your pharmacist first. In any case, do not apply them at the same time: apply minoxidil to a dry scalp and dry hair^[1].

When should you first go to the doctor?

Rosemary oil and minoxidil are both intended for gradual, hereditary hair loss. If you have sudden or localized hair loss, such as alopecia areata, you should first visit your doctor. This also applies if you have a cardiovascular disease or high blood pressure, are pregnant or want to become pregnant, or are younger than 18^[1][6].

Frequently asked questions

Is rosemary oil as good as minoxidil?

That has not been proven. In the only comparative study, rosemary oil performed approximately as well as minoxidil 2% after 6 months, but there was no placebo group and no comparison was made with the stronger 5%^[2][5].

How long should you use rosemary oil for results?

In the study, no difference was visible after 3 months and after 6 months there was a difference^[2]. So count on at least six months of daily use, without guarantee of results.

Can I use rosemary oil and minoxidil at the same time?

There is no research into the combination. Do not use other skin products on your scalp besides minoxidil without consulting your doctor or pharmacist^[1].

Is rosemary oil safe for the scalp?

Not without a doubt: essential oil can irritate or cause an allergic reaction^[5]. Therefore, always use essential oil diluted and stop if there is redness, itching or rash.

Does minoxidil also work for women?

Yes, minoxidil is intended for hair loss according to the male and female pattern^[1]. At Minodeals you will find 2% lotions and a 5% foam for women; always read the package leaflet of the product you choose.
