Minoxidil has a clear clinical advantage in promoting faster hair regrowth in individuals with genetic hair loss when compared with rosemary oil. However, rosemary oil is a worthy alternative as a natural remedy for mild to moderate hair loss with fewer side effects.
This blog breaks down the science behind both, dives deep into the rosemary oil vs minoxidil hair growth study, and helps you determine which approach makes the most sense for your hair.
What is rosemary oil?
Rosemary oil is an essential oil extracted from the rosemary plant leaves (Rosemarinus officinalis). With deep roots in Ayurvedic and Mediterranean healing traditions, rosemary oil has become widely known as a low-risk option to treat mild to moderate hair loss. But whether it’s an effective alternative to minoxidil is yet to be seen.
Impact of rosemary oil on your hair
The impact of rosemary oil on hair is well-documented. However, its relevance to hair growth depends on a specific set of features:
- Antioxidant properties - Rosemary oil contains anti-inflammatory and antimicrobial properties that fight scalp infections.
- Vasodilation - Rosemary oil widens blood vessels, improving microcirculation and providing a steady supply of oxygen and nutrients to hair follicles.
- DHT inhibition - It contains anti-androgenic properties that block Dihydrotestosterone (DHT), linked to hair shrinkage in pattern hair loss.
- Scalp soothing - Its natural compounds calm irritation, dryness, and itchiness without the chemical overload of synthetic treatments.
What is minoxidil?
When it’s about treating hair loss, the first solution that comes to mind is Minoxidil, or Rogaine. This FDA-approved, over-the-counter solution is primarily available in two concentrations: 2% for women (to reduce the risk of unwanted facial hair growth) and 5% for men.
How does minoxidil affect your hair?
Initially, minoxidil was used to treat high blood pressure. But one of its side effects, surprisingly, led to hair growth, making it a topical treatment. Here are some ways this medication helps with hair growth:
- Vasodilation - Similar to rosemary oil, minoxidil acts as a vasodilator by opening up your blood vessels. It does so more aggressively and at a deeper follicular level, increasing blood flow to the papilla (where hair growth begins).
- Extends the anagen phase - Minoxidil prolongs the growth phase of the hair follicles, keeping them active and productive for longer before they enter the resting phase.
Rosemary oil vs minoxidil: Hair growth study
A 2015 study compared rosemary oil with 2% minoxidil for treating AGA over a span of 6 months. Two groups of patients with AGA were randomly assigned to receive rosemary oil or a 2% minoxidil solution. The two groups were assessed via microphotographic hair counts at the 3 and 6-month marks. This study noted the following findings:
- No changes were observed after 3 months, indicating that both treatments require sustained use to show results.
- At six months, both groups experienced a significant increase in hair count, suggesting that both rosemary oil and minoxidil were equally effective at promoting hair growth in patients with AGA.
- Participants who used rosemary oil experienced fewer side effects than those assigned minoxidil, who reported scalp itching.
While these results position rosemary oil as a lower-risk alternative to low-dose minoxidil, there are several limitations to the rosemary oil vs minoxidil hair growth study:
- The study used a weaker concentration of minoxidil (2%).
- It focused on only one type of hair loss (AGA).
- The study compared rosemary oil to 2% minoxidil while the current market standard is 5%.
Minoxidil or rosemary oil: Which is better?
So, between minoxidil or rosemary oil, which is better? We need to understand the cost, long-term sustainability, and risk aspects to infer which options work better. Here’s a table that explains it concisely:

Can I use minoxidil and rosemary oil together?
Rosemary oil vs minoxidil are often pitted against each other. If you’re wondering, can I use minoxidil and rosemary oil together? - Yes, they can be used, but not simultaneously. The challenge is one of absorption.
Topical minoxidil requires a clean, dry scalp to penetrate effectively. It comes in liquid or foam form and is applied to the affected areas of the scalp. Layering rosemary oil on top of minoxidil (or vice versa) creates a barrier that compromises the absorption of whichever is applied second, thereby reducing the efficacy of both.
Here is a structured routine to apply both without any overlap:
- Massage minoxidil into a clean scalp in the morning.
- Infuse diluted rosemary oil as a pre-shampoo treatment, then leave it on for 30-60 minutes for absorption.
- If you’re applying rosemary oil and minoxidil on the same day, allow a minimum of 4-6 hours to avoid cross-barrier interference.
