How to Make Rosemary Water for Hair Growth and Health

An Overview of Rosemary Water and Its Effects on Hair

Rosemary water has become a popular DIY hair care ingredient, with many claims surrounding its ability to improve hair growth, health and shine. But what does the science say?

Here's a comprehensive look at rosemary water for hair and how to make it at home.

What Is Rosemary Water?

Rosemary water is made by infusing fresh or dried rosemary leaves in hot water. This allows the rosemary's aromatic oils and plant compounds to leach into the water.

It can be used on your hair or skin after cooling. Some people also drink rosemary tea for potential health benefits.

Benefits of Rosemary for Hair

Rosemary has long been used in folk medicine for hair care. Modern science is still catching up, but early lab and animal research lends some plausibility to rosemary's traditional hair uses.

May Promote Hair Growth

In one study, topical application of rosemary leaf extract significantly increased hair growth in mice after 28 days, comparable to the drug minoxidil (Rogaine) (1).

Researchers attributed this effect to rosemary's anti-inflammatory and anti-androgenic effects. Additional animal studies report similar hair growth benefits (2, 3).

However, keep in mind that animal and lab studies don't always translate to the same effects in humans.

May Increase Blood Circulation

One small study in 20 people with hair loss examined a rosemary oil scalp massage. After 7 months, those receiving the massage had significantly increased hair count compared to the control group (4).

Researchers noted increased scalp circulation from the massage, which may have stimulated hair follicles.

Contains Antioxidants

Rosemary contains antioxidants like rosmarinic acid, carnosic acid and carnosol (5).

Test-tube studies show these compounds strengthen hair follicles and encourage growth by increasing blood flow and reducing oxidative stress and inflammation (6, 7).

Still, more human research is needed.

Other Potential Hair Benefits

There are a few other possible ways rosemary may improve hair health, though research is limited.

May Increase Shine

Some natural health enthusiasts claim that rosemary water adds shine. This may be related to a purported sealing effect that smooths hair cuticles.

However, no studies have examined rosemary's effects on hair shine.

May Soothe an Itchy Scalp

Dandruff and dry scalp can cause itching. Rosemary's anti-inflammatory properties may help and some shampoos already contain rosemary extract.

That said, research has not directly assessed rosemary water's effects on an itchy scalp.

May Neutralize Odor

Rosemary has antimicrobial properties that may neutralize odors (5). Anecdotally, some people add it to their shampoo or hair rinse to act as a natural deodorizer.

However, no studies confirm rosemary's effects on scalp odor.

How to Make Rosemary Water for Hair

It's easy to make rosemary water at home using either fresh or dried rosemary.

Ingredients

• 24 sprigs fresh rosemary or 2 tablespoons (7 grams) dried
• 2 cups (500 mL) boiling water

Instructions

1. Remove rosemary leaves from stems if using fresh rosemary. For both fresh and dried, place leaves in a heatproof container.
2. Pour boiling water over the leaves and steep for 1530 minutes.
3. Strain to remove leaves.
4. Allow rosemary water to cool fully before use. Pour into a spray bottle or applicator for easy use.
5. Store leftover rosemary water in the fridge for up to 5 days.

Tips

• Use more rosemary for stronger infusion.
• Steep longer for more potent rosemary water.
• Submerge rosemary leaves in water to infuse fully.
• Make in larger batches and store in the refrigerator.

How to Use Rosemary Water for Hair

There are several ways to use rosemary water in your hair care routine:

Final Rinse

After shampooing and conditioning, pour rosemary water through your hair as a final rinse before getting out of the shower. Start at the scalp for full coverage.

Pre-Shampoo Treatment

For an intensive treatment, apply rosemary water to your scalp and hair about 30 minutes before shampooing. You can also massage it in for added circulation.

Scalp Massage

Apply rosemary water directly to your scalp and massage for several minutes to increase blood flow.

Spritz Between Washes

To refresh hair between washes, lightly mist your scalp and hair with rosemary water and style as usual.

Combine With Oils

For extra moisture, mix a few teaspoons of oil like olive or coconut into rosemary water before applying to your hair.

Safety and Side Effects

Rosemary water is generally safe with minimal risk of side effects. However, take these precautions:

• Do a skin patch test before first use to check for allergic reaction.
• Avoid getting any oils or extracts in your eyes.
• Discontinue use if irritation occurs.
• Don't use if pregnant, as safety is uncertain.
• May interact with blood thinners, so consult your healthcare provider.

Should You Try Rosemary Water for Your Hair?

Based on limited evidence, rosemary water could possibly support hair growth, blood circulation, shine and more.

It's easy to make at home and safe for most people when used topically.

While research is still emerging, beauty lovers and natural product fans may want to give rosemary water a try in their hair care regimens.

However, rosemary water shouldn't replace conventional treatments if you have significant hair loss or thinning.

Other Tips for Healthy Hair

In addition to rosemary water, several other tips can optimize hair health:

Get Enough Protein

Eat protein-rich foods like eggs, nuts, beans and seafood. Protein is essential for hair growth.

Take a Multivitamin

A supplement containing zinc, iron, biotin and other nutrients benefits hair.

Use Gentle Products

Minimize use of heat tools and opt for gentle, sulfate-free shampoos and conditioners.

Reduce Stress

Chronic stress takes a toll on your hair. Try relaxing techniques like yoga, meditation or massage.

Address Health Conditions

See your healthcare provider for thinning hair, as it may indicate an underlying issue.

The Bottom Line

Rosemary water is linked to several benefits for hair growth and health, though research is limited.

It's simple to make at home by steeping fresh rosemary leaves in hot water. For best results, apply to your scalp and hair a few times per week.

While more studies are needed, rosemary water is generally safe to try on your hair if you're intrigued by the potential benefits.
