What if one of the most interesting ingredients in hair care has been growing in gardens for centuries?
Rosemary is familiar as a culinary herb, but its essential oil has also attracted scientific interest for its potential role in supporting hair growth. In a six-month clinical trial involving 100 people with pattern hair loss, researchers found increased hair counts in the rosemary oil group. The results were comparable to those observed with 2% minoxidil in that study, with no statistically significant difference in hair count between groups at six months.
There was another interesting finding: scalp itching was more frequent in the minoxidil group.
Let's look at what the researchers found, why the type of rosemary matters, and how to build a practical scalp-care routine.
Rosemary oil vs. minoxidil: what did the study find?
In 2015, researchers published a randomized comparative trial in SKINmed involving 100 people with androgenetic alopecia, or pattern hair loss. Fifty participants used a rosemary oil preparation and fifty used 2% minoxidil for six months.
- After three months: Neither group showed a statistically significant increase in hair count.
- After six months: Both groups showed a statistically significant increase in hair count from baseline.
- Between the groups: The difference in hair count was not statistically significant at six months.
- Scalp comfort: Itching was reported more frequently in the minoxidil group.
Those findings make rosemary oil worth taking seriously as a plant-based ingredient for a consistent hair-care routine. The study also offers a useful reminder: meaningful changes in hair count were measured over months, not days.

Not all rosemary oil is the same
Rosemary essential oils vary in their natural aromatic compounds. One important compound is 1,8-cineole, and rosemary oils identified as ct. cineole have a chemical profile in which cineole is a defining component.
Beautimate deliberately uses rosemary essential oil, chemotype cineole, in its hair serum. That is a relevant botanical connection when discussing rosemary research, though the finished Beautimate formula is not the same preparation tested in the 2015 trial.
What's in Beautimate's rosemary hair serum?
- 5% organic rosemary essential oil (ct. cineole)
- 95% organic cold-pressed castor oil
- 4 oz bottle, made in the USA
The castor-oil base conditions hair and helps dilute the essential oil into a ready-to-use scalp product. No measuring or mixing required.
Where does microneedling fit in?
Rosemary oil isn't the only approach that has caught researchers' attention. Scalp microneedling has also been studied for pattern hair loss, often as part of clinical treatment protocols. Microneedling uses fine needles to make controlled punctures in the skin, and researchers continue to study its effects on the scalp.
Clinical protocols can use depths and techniques that aren't suitable to copy at home. For a home routine, the priority is control, cleanliness, and a conservative depth.
Derma stamp vs. derma roller
A derma stamp presses straight down and lifts away, which can make it convenient for targeted areas such as the hairline or part line. A derma roller moves across larger areas of the scalp. Both have their place, depending on how you prefer to work.
Beautimate's Adjustable Derma Stamp has a 140-pin stainless-steel head and an adjustable dial. Although its dial allows deeper settings, we recommend staying at or below 0.5 mm for at-home use.
A simple rosemary oil and scalp-care routine
Good routines are the ones you can follow consistently. You can include rosemary serum and a derma stamp in the same overall routine, but there's no need to apply them together in the same session.
On rosemary serum days
- Start with a clean, comfortable scalp.
- Part your hair to expose the areas you want to focus on.
- Apply a small amount of serum to intact scalp skin.
- Massage gently with your fingertips.
- Adjust the amount and frequency to what feels comfortable for your scalp.
Patch-test before regular use, particularly if your scalp is sensitive.
On derma stamp days
- Start clean. Avoid stamping irritated, infected, inflamed, or broken skin.
- Sanitize the needle head. Follow the product instructions with 70% isopropyl alcohol, then allow it to air-dry. Do not submerge the handle or share the tool.
- Choose a conservative setting. Stay within 0.25–0.5 mm for home use.
- Part the hair. Press gently and lift the stamp straight up before moving. Don't drag the needles across the scalp.
- Give your scalp recovery time. Avoid essential oils on freshly stamped skin. Resume your serum routine after any redness or sensitivity has resolved.
For conservative home use, allow at least a week between stamping sessions and longer if the scalp needs more time.
How long should you give a rosemary routine?
One of the most useful takeaways from the clinical study is the timeline: researchers observed a significant increase in hair count at six months, but not at three months. Hair grows slowly, and the cause of thinning influences what changes are possible.
Rather than checking every day, consider taking a monthly photograph of your hairline or part line in the same lighting. It's a practical way to see gradual changes over time.

Frequently asked questions
Can rosemary oil help with thinning hair?
Clinical research suggests it can. In a six-month trial, participants using rosemary oil experienced a significant increase in hair count. The study found no statistically significant difference in hair count between the rosemary oil and 2% minoxidil groups at six months.
Why does rosemary ct. cineole matter?
Rosemary oils can differ in their natural composition. Beautimate uses rosemary essential oil of the cineole chemotype, a deliberate ingredient choice informed by the importance of identifying the type of rosemary used in a formulation.
Did the rosemary group experience less itching?
In the 2015 clinical trial, scalp itching was more frequent in the minoxidil group. As with any essential oil product, patch-testing rosemary serum is still a sensible first step.
Can I use rosemary serum without microneedling?
Absolutely. The rosemary oil clinical trial studied rosemary oil independently. A derma stamp is optional.
Can I apply rosemary oil immediately after stamping?
We recommend keeping these steps separate. Freshly stamped skin is more sensitive, so wait until the scalp has recovered before applying essential-oil serum.
How long does rosemary oil take to show changes?
The 2015 study observed increased hair counts after six months, not three. Individual experiences can vary.
