Hair loss is one of the most distressing symptoms many women with PCOS experience. Between 40-60% of women with Polycystic Ovary Syndrome report some degree of hair thinning or loss, often due to the hormonal imbalances that characterize the condition. If you're looking for natural solutions, rosemary water has emerged as a promising option worth exploring.
Understanding PCOS-Related Hair Loss
Before diving into solutions, it helps to understand why PCOS often leads to hair loss. The primary culprit is typically elevated androgen levels (male hormones) that can trigger a condition called androgenic alopecia or female pattern hair loss.
In women with PCOS, excess androgens can:
- Convert to dihydrotestosterone (DHT), which shrinks hair follicles
- Shorten the growth phase of hair
- Lengthen the resting phase of hair follicles
- Result in progressively thinner, shorter, and fewer hairs
This type of hair loss typically affects the crown and top of the head, often creating a widening part while preserving the frontal hairline.
What is Rosemary Water?
Rosemary water is an infusion made from the leaves of the rosemary plant (Rosmarinus officinalis). This aromatic herb has been used for centuries in traditional medicine for various purposes, including stimulating hair growth.
You can prepare rosemary water by:
- Steeping fresh or dried rosemary in hot water
- Creating a more concentrated decoction by simmering rosemary in water
- Making a cold infusion by soaking rosemary in water for 12-24 hours
The resulting liquid contains beneficial compounds from the herb that can be applied directly to the scalp.
How Rosemary Water May Help with PCOS Hair Loss
DHT Blocking Properties
One of the most promising benefits of rosemary for PCOS-related hair loss is its potential to block DHT (dihydrotestosterone). Research suggests that rosemary contains carnosic acid and rosmarinic acid, compounds that may inhibit 5-alpha-reductase, the enzyme that converts testosterone to DHT.
By helping to block DHT at the scalp level, rosemary water might help address one of the root causes of PCOS hair thinning.
Improved Blood Circulation
Rosemary has been shown to stimulate blood circulation when applied topically. Better blood flow to hair follicles means:
- More oxygen delivery to follicle cells
- Enhanced nutrient delivery
- Removal of waste products and DHT from the follicle area
This improved circulation may help revitalize dormant hair follicles and support the growth of existing hair.
Anti-inflammatory Properties
Inflammation can contribute to hair loss, and chronic low-grade inflammation is common in PCOS. Rosemary contains anti-inflammatory compounds that may help soothe the scalp and create a healthier environment for hair growth.
Antioxidant Effects
Oxidative stress can damage hair follicles and contribute to hair loss. Rosemary is rich in antioxidants that help neutralize free radicals and protect follicles from oxidative damage.
Scientific Evidence for Rosemary and Hair Growth
While research specifically on rosemary water for PCOS-related hair loss is limited, several studies have examined rosemary's effects on hair growth:
- A 2015 study published in SKINmed Journal compared rosemary oil to minoxidil (2%) for androgenetic alopecia. After six months, both treatments showed significant increases in hair count with similar effectiveness.
- Research published in Phytotherapy Research found that rosemary leaf extract promoted hair growth in mice by inhibiting the binding of DHT to androgen receptors.
- A study in the Journal of Medicinal Food demonstrated that carnosic acid from rosemary stimulated nerve growth factor, which may help with hair regrowth.
While these studies primarily focused on rosemary oil or extract rather than rosemary water, they suggest that the active compounds in rosemary may benefit hair growth.
How to Make Rosemary Water for Hair
Creating your own rosemary water is simple and affordable. Here's a basic recipe:
Basic Rosemary Water Infusion
Ingredients:
- 2-3 sprigs of fresh rosemary (or 2 tablespoons dried rosemary)
- 2 cups of filtered water
Instructions:
- Bring water to a boil in a small pot
- Add rosemary sprigs or dried herb
- Reduce heat and simmer for 15-20 minutes
- Remove from heat and let steep until completely cooled
- Strain the liquid into a clean container (preferably a spray bottle)
- Store in the refrigerator for up to one week
Stronger Rosemary Decoction
For a more concentrated preparation:
- Use 1/4 cup dried rosemary (or 1/2 cup fresh) to 2 cups water
- Simmer for 30-45 minutes, or until the water is reduced by half
- Cool, strain, and store as above
How to Use Rosemary Water for PCOS Hair Loss
Direct Scalp Application
The most common method is to apply rosemary water directly to your scalp:
- After shampooing, towel-dry your hair until damp
- Apply rosemary water to your scalp, focusing on areas with thinning
- Gently massage for 3-5 minutes to stimulate circulation
- Leave in (no need to rinse)
- Style hair as usual
Rosemary Water Spray
For daily use between washes:
- Fill a spray bottle with your rosemary water
- Spritz onto your scalp daily, focusing on problem areas
- Massage gently after application
Rosemary Water Rinse
As a final rinse after shampooing:
- After shampooing and conditioning, pour rosemary water over your hair as a final rinse
- Do not rinse out
Consistency is Key
With any natural hair loss remedy, patience and consistency are crucial:
- Use rosemary water at least 3-4 times per week
- Results typically take 3-6 months to become noticeable
- Take "before" photos to help track progress
- Continue use even after seeing improvements to maintain results
Complementary Approaches for PCOS Hair Loss
While rosemary water can be helpful, addressing PCOS-related hair loss is most effective with a multi-faceted approach:
Diet and Nutrition
Focus on foods that help balance hormones and reduce inflammation:
- Anti-inflammatory foods rich in omega-3 fatty acids
- Low-glycemic foods to help manage insulin resistance
- Zinc-rich foods like pumpkin seeds, oysters, and beef
- Iron-rich foods (if deficient) such as leafy greens and lentils
- Foods high in antioxidants and polyphenols
Stress Management
Stress can worsen both PCOS symptoms and hair loss:
- Regular meditation or mindfulness practice
- Adequate sleep (7-9 hours nightly)
- Regular physical activity
- Breathing exercises or yoga
Medical Treatments
Work with your healthcare provider to explore:
- Hormonal treatments like birth control pills or anti-androgens
- Medications like spironolactone that can help with androgen-related hair loss
- Supplements like inositol that may help manage PCOS symptoms
Potential Side Effects and Precautions
Rosemary water is generally safe for most people when used topically, but be aware of:
- Possible skin irritation or allergic reactions (do a patch test first)
- Rosemary should not be used in very high concentrations during pregnancy
- If you have sensitive skin, dilute your rosemary water or reduce application frequency
- Discontinue use if you experience scalp irritation, redness, or increased hair shedding
Other Helpful Herbs for PCOS Hair Loss
You might consider combining rosemary with other beneficial herbs:
- Saw palmetto: Another natural DHT blocker
- Peppermint: Stimulates circulation and creates a cooling sensation
- Nettle: Contains compounds that may help reduce DHT levels
- Lavender: Has antimicrobial properties and may help with stress-related hair loss
- Horsetail: Rich in silica which supports hair strength
The Bottom Line
Rosemary water offers a natural, affordable option for women dealing with PCOS-related hair loss. Its potential DHT-blocking properties, ability to improve circulation, and anti-inflammatory effects make it worth trying as part of a comprehensive approach to managing hair thinning.
Remember that addressing the root causes of PCOS—including hormone imbalances, insulin resistance, and inflammation—is essential for long-term improvement in hair growth. While rosemary water can be a helpful addition to your hair care routine, it works best when combined with dietary changes, stress management, and appropriate medical treatment for your PCOS.
Extra Tip
To enhance the effectiveness of your rosemary water, consider adding a few drops of peppermint essential oil to your preparation. Peppermint has been shown to promote hair growth in some studies and creates a pleasant tingling sensation that may further stimulate blood flow to the scalp.
