Explore 7 natural oils that can help combat PCOS-related hair loss and improve scalp health through hormonal balance and nourishment.
Hair loss is a common issue for women with PCOS, affecting up to 70%. Hormonal imbalances, particularly excess androgens like DHT, can shrink hair follicles, leading to thinning, breakage, and scalp dryness. Natural oils offer a promising way to support hair regrowth and improve scalp health.
Here are 7 oils worth trying:
How to use them: Always dilute essential oils with a carrier oil (like coconut or jojoba), massage into the scalp, and leave for at least 10 minutes before washing. Consistency is key, as results may take months to appear.
If hair loss persists or worsens, consult a dermatologist or endocrinologist for targeted treatments.
Hair loss related to PCOS is largely driven by hormonal imbalances. Elevated levels of androgens, particularly dihydrotestosterone (DHT), play a key role in this process. DHT, which is about five times more potent than testosterone, becomes problematic due to increased activity of the enzyme 5-alpha-reductase and lower levels of sex hormone-binding globulin (SHBG).
When DHT binds to androgen receptors in hair follicles on the scalp, it causes the follicles to shrink. This disrupts the hair growth cycle, shortening the anagen (growth) phase. Typically, around 90% of hair follicles are in this phase, but high androgen levels can lead to quicker shedding and reduced hair density.
Insulin resistance adds another layer to the problem. High insulin levels can boost androgen production and promote inflammation, further disrupting the hair cycle. This inflammation can push more hair follicles into the telogen (resting) phase, leading to noticeable hair thinning and increased shedding. In some cases, inflammation may also weaken the hair, making it brittle and more prone to breakage. These combined hormonal and metabolic changes often result in androgenic alopecia, commonly known as female pattern hair loss.
Androgenic alopecia typically appears as thinning at the crown and temples. Interestingly, it often takes a loss of 20–25% of scalp hair before the thinning becomes visibly apparent. While high androgen levels contribute to scalp hair loss, they can also stimulate hair growth in areas like the upper lip and chin, which explains why PCOS can cause both hair loss and unwanted hair growth (hirsutism) at the same time.
Addressing this issue early is crucial. Steps like balancing hormones, improving insulin sensitivity through regular exercise, following a low-glycemic diet, and using appropriate supplements or medications can help interrupt the cycle of hair loss.
Coconut oil is a multi-purpose and easily accessible option for addressing PCOS-related hair loss. Unlike many other oils that merely coat the hair surface, its unique molecular structure allows it to deeply penetrate the hair shaft. This deep action not only nourishes the hair but also promotes a healthier scalp environment.
For women with PCOS, scalp health can be a significant concern due to elevated androgen levels, which often lead to issues like dandruff. Studies show that dandruff affects about 50% of people, and hormonal imbalances in PCOS can make it worse. Coconut oil’s moisturizing properties are especially helpful for dry scalp conditions or issues like eczema. It also creates a less hospitable environment for fungi that can cause dandruff and irritation. Regular scalp massages with coconut oil can hydrate the scalp and reduce dandruff.
Coconut oil also plays a role in supporting hair regrowth. Hair thinning is a common issue among women with PCOS, with up to 30% experiencing female-pattern hair loss. Coconut oil’s ability to deeply penetrate the scalp and hair helps reduce protein loss, which is essential for maintaining hair strength and preventing breakage. Additionally, its nourishing properties may help reduce hair fall. Amy Plano, known as The PCOS Dietitian, highlights the benefits of topical application:
"In addition, topical coconut oil has been shown to have a positive effect when rubbed consistently on thinning hair related to PCOS."
Coconut oil’s anti-inflammatory properties further contribute to scalp health. Research has shown that cultured coconut extract can lower inflammation markers in human skin samples, with similar effects observed when virgin coconut oil is applied to artificial skin models. This is particularly important because scalp irritation and dryness can indirectly worsen hair loss. For best results, opt for unrefined, organic, cold-pressed (virgin) coconut oil. Incorporating regular scalp massages can also improve blood circulation and enhance these anti-inflammatory effects.
Castor oil is packed with ricinoleic acid - a whopping 90% of its composition. This makes it a powerhouse for delivering nutrients and locking in moisture, benefiting both the scalp and hair follicles. Its unique properties make it a go-to for improving scalp health, encouraging hair regrowth, and reducing inflammation.
For women with PCOS, scalp health can be a challenge due to hormonal imbalances and inflammation. Castor oil’s antifungal and antimicrobial qualities help create a cleaner, healthier scalp environment, reducing the risk of infections that could disrupt hair growth. Its high ricinoleic acid content deeply moisturizes and nourishes hair follicles, making it especially useful for dry or flaky scalps. Regularly massaging castor oil into the scalp can also boost blood circulation, delivering essential nutrients to hair follicles impacted by hormonal shifts.
If thinning hair is a concern, castor oil might be worth a try. The ricinoleic acid it contains - an omega-3 fatty acid - is believed to support hair growth by improving blood flow to the scalp. This creates the ideal conditions for healthy hair development. Plus, its moisturizing properties help reduce breakage and enhance overall hair strength. In one study, a lotion with 35% castor oil was shown to increase the length, thickness, and softness of rabbit hair without any adverse effects.
Scalp inflammation can interfere with hair follicle function and lead to various skin issues. Castor oil’s anti-inflammatory properties come into play here. Ricinoleic acid works by inhibiting COX-2 enzymes, which are linked to pain and swelling. Clinical trials have shown a 68% reduction in CRP markers - an indicator of systemic inflammation - when using castor oil. This can lower the risk of infections and improve the overall health of hair follicles.
Interestingly, castor oil may also play a role in balancing hormones. It’s thought to enhance pelvic circulation and support lymphatic drainage, which could indirectly benefit hormonal health.
To get the most out of castor oil, massage a small amount onto your scalp for a few minutes. You can use it on its own or mix it with a lighter oil like coconut oil. Leave it on for at least 10 minutes - or even overnight - before washing it out. Just make sure to do a patch test first to rule out any allergies. Castor oil offers a versatile approach to addressing scalp health and hormonal concerns linked to PCOS.
Rosemary oil is a fragrant essential oil packed with compounds like caffeic acid, 1,8‐cineole, and rosmarinic acid. These ingredients work together to enhance blood flow to the scalp and promote the regeneration of hair follicles. This improved circulation creates an ideal environment for hair regrowth.
Research has shown that rosemary oil can be just as effective as minoxidil, a widely used treatment for hair loss, in encouraging hair growth in men with androgenic alopecia. In one study, participants experienced noticeable increases in hair count within six months of using rosemary oil. When applied topically, its active components stimulate scalp circulation, delivering essential nutrients and oxygen to the hair follicles.
Rosemary oil not only promotes hair growth but also supports overall scalp health. It helps regulate sebum production and reduces inflammation thanks to its antimicrobial and antioxidant properties. These antioxidants protect hair follicles from oxidative stress, while its moisturizing qualities alleviate dryness and irritation. Additionally, rosemary oil may lower scalp DHT levels - a hormone linked to hair thinning, especially in women with PCOS.
One of the standout compounds in rosemary oil is carnosic acid, known for its anti-inflammatory and antioxidant effects. These qualities make it effective in reducing scalp inflammation, a common issue in PCOS-related hair loss. Interestingly, studies suggest that rosemary oil is gentler on the scalp compared to minoxidil, making it a suitable option for those with sensitive skin.
To use rosemary oil, mix five drops with a carrier oil like jojoba or coconut oil and massage it into your scalp for 5–10 minutes a few times a week. You can also add 2–3 drops to your shampoo or create a rosemary rinse by steeping rosemary leaves in water and using the cooled infusion as a final rinse.
Pumpkin seed oil is a powerful ally in addressing hair loss, particularly when it’s linked to PCOS and hormonal imbalances. By promoting hair regrowth and supporting hormonal balance, this oil tackles androgenic alopecia while also enhancing scalp health. Packed with essential fatty acids, vitamin E, and phytosterols, it works to reduce hair thinning and improve overall scalp wellness.
Pumpkin seed oil has shown impressive results in promoting hair regrowth. In a well-designed clinical study, men who took 400mg of pumpkin seed oil daily for 24 weeks saw a 40% increase in hair count, compared to only 10% in the placebo group.
Animal studies have also highlighted its potential. Research using mice suggests that topical application of pumpkin seed oil could be a promising alternative for treating male pattern alopecia. Its benefits for hair regrowth make it a compelling option to explore for PCOS-related hair loss.
One of the most significant benefits of pumpkin seed oil is its ability to support hormonal balance, which is crucial for women dealing with PCOS. The oil contains beta-sitosterol, a plant compound that helps reduce excess androgens, addressing symptoms like hair thinning and excessive hair growth. It also inhibits the enzyme 5-alpha reductase, which converts testosterone into DHT - a key contributor to hair loss.
"When people have an excess of DHT, it can lead to things like hair loss. Taking pumpkin seed oil might help to lower the excess DHT that can contribute to loss of hair." - Dr. Wilma Bergfeld, Dermatologist
Pumpkin seed oil is also rich in zinc, which helps regulate estrogen, progesterone, and testosterone levels. Its high vitamin E content supports progesterone production while providing antioxidant protection. Additionally, omega-3 fatty acids in the oil help manage elevated insulin and cholesterol levels, both of which are commonly linked to PCOS.
Pumpkin seed oil doesn’t just stop at hormonal support; it also improves scalp health. Its moisturizing properties help combat dryness and flakiness, which can exacerbate hair loss. When massaged into the scalp, it reduces irritation and nourishes hair follicles, encouraging healthy regrowth.
By improving scalp moisture and reducing inflammation, pumpkin seed oil creates an environment where hair can thrive.
The anti-inflammatory effects of pumpkin seed oil play a key role in addressing scalp inflammation often associated with PCOS-related hair loss. Its antioxidants protect hair follicles from damage, while its soothing properties help break the cycle of irritation that can worsen hair thinning.
For a DIY topical treatment, mix 4-6 ounces of cold-pressed pumpkin seed oil with 3 drops of peppermint essential oil and 3-5 drops of rosemary essential oil. Massage this blend into your scalp for 10-15 minutes. You can leave it on overnight or rinse it out after the massage. For the best results, opt for cold-pressed, organic, and GMP-certified pumpkin seed oil.
Saw palmetto oil is a plant-based remedy often used to help manage hormonal imbalances in women with PCOS. It works by reducing the activity of 5-alpha reductase, an enzyme that converts testosterone into DHT. Packed with fatty acids and anti-inflammatory components, this oil offers a natural way to address hormonal issues.
One of saw palmetto oil's key benefits is its ability to help regulate hormones that contribute to hair loss in PCOS. It contains liposterols - such as lauric, oleic, myristic, and linoleic acids - that inhibit 5-alpha reductase activity. Lowering DHT levels can also reduce testosterone levels, potentially alleviating PCOS symptoms like hair thinning. Additionally, saw palmetto may decrease the prolactin receptor response in ovarian cells, further contributing to hormonal balance.
"We usually think of saw palmetto for men and prostates, but this supplement can benefit women too."
– Dr. Kirby, Nurse Practitioner at Health and Wellness Made Easy
These hormonal effects create an environment that may support hair regrowth.
Beyond hormonal regulation, some studies suggest saw palmetto might encourage hair regrowth, particularly in cases of androgenetic alopecia. Research highlights improvements in total hair count ranging from 3.4% to 27%, with up to 83.3% of patients experiencing increased hair density when using saw palmetto-based supplements or topical treatments. In one 24-week study, participants applying a saw palmetto lotion saw a 3.4% increase in total hair count at 12 weeks, which rose to 4.9% at 24 weeks. Terminal hair count also improved significantly, jumping by 21.4% at 12 weeks and 74.1% at 24 weeks. Additionally, 52% of participants experienced a stabilization in hair loss progression, a critical benefit for women with PCOS who often face rapid hair thinning.
When applied directly to the scalp, saw palmetto oil offers further advantages. Its fatty acids and antioxidants help hydrate the scalp and reduce inflammation, creating a healthier environment for hair growth. Products like shampoos infused with saw palmetto or serums designed for thinning areas can be effective options.
Saw palmetto oil’s anti-inflammatory properties make it particularly useful for addressing conditions like telogen effluvium, which can accompany PCOS-related hair loss. Its β-sitosterol content may enhance blood flow by stimulating vascular endothelial growth factor, encouraging the development of new blood vessels around hair follicles. This improved circulation supports hair growth and helps reduce chronic inflammation, which can exacerbate PCOS symptoms.
"The potential benefits of saw palmetto are very promising, although individual responses may vary. It is always best to consult with a healthcare professional before taking them, especially if you have underlying health conditions or are taking other medication."
– Catherine Gervacio, Registered Dietitian at Living Fit
Lavender oil stands out as a natural remedy for managing PCOS-related hair loss while also enhancing overall well-being. Its gentle nature and calming scent make it a versatile addition to self-care routines.
Lavender oil is thought to support hair growth by improving blood flow to the scalp and alleviating stress - two factors that play a key role in healthier hair growth. Its calming properties may also encourage better sleep, which is essential for overall health. To use, combine 3–4 drops of lavender oil with a carrier oil like coconut or jojoba, massage it into the scalp, and leave it on for several hours or overnight.
Since PCOS often involves inflammation, lavender oil’s anti-inflammatory qualities can help soothe irritation and reduce inflammation that might hinder hair growth. It can also provide relief from discomfort caused by conditions like ovarian cysts or endometriosis pain.
Lavender oil may assist in balancing hormones by reducing unwanted hair growth (hirsutism) while encouraging healthy hair growth where needed. Its stress-relieving and sleep-enhancing effects further support hormonal regulation. These benefits make lavender oil an excellent choice for nurturing both the scalp and overall well-being.
In addition to promoting hair growth, lavender oil helps maintain a healthy scalp. Its soothing and hydrating properties can calm irritation and create an ideal environment for hair to thrive. You can integrate it into your routine by adding a few drops to a diffuser, mixing it into lotion or bathwater, or applying it directly to the scalp after diluting with a carrier oil.
Clary sage oil, extracted from Salvia officinalis, is a popular choice for addressing hair loss, particularly for those dealing with PCOS-related issues. Known for its long history in health and beauty remedies, this oil combines hair growth support with hormonal balancing properties, making it a natural ally for overall scalp health and regrowth potential.
One of the standout components of clary sage oil is linalyl acetate, which is also found in lavender oil. This compound is known to strengthen hair strands and encourage regrowth, making hair more resilient to breakage.
To use clary sage oil for hair growth:
In addition to its regrowth benefits, clary sage oil helps regulate hormones, which is crucial for addressing PCOS-related hair loss.
Clary sage oil is celebrated for its ability to help stabilize hormonal fluctuations, a common challenge for individuals with PCOS. Natalie Underberg, also known as The PCOS Doc, highlights its benefits:
"For hormone balance, clary sage is a superstar. Known for its ability to support estrogen levels, clary sage oil can help stabilize hormonal fluctuations that are characteristic of PCOS".
A study conducted in Korea found that inhaling clary sage oil reduced cortisol levels by 36% and improved thyroid hormone levels in menopausal women. Since elevated cortisol can exacerbate hair loss in PCOS, this stress-reducing effect may indirectly support healthier hair.
Tallene from PCOSWeightLoss.org also emphasizes its broader benefits:
"Research suggests there is a lot clary sage essential oil can do for PCOS. It's been shown to potentially help lower stress hormones (cortisol), boost hair growth, reduce acne, and relieve period pain."
For hormonal support, you can inhale clary sage oil or apply it topically after diluting it with a carrier oil. These methods complement its effectiveness in managing PCOS-related hair concerns.
Clary sage oil also boasts anti-inflammatory and antioxidant properties, which are crucial for addressing PCOS-related inflammation. Chronic inflammation can disrupt healthy hair growth, but clary sage oil helps calm the scalp, creating a healthier environment for hair to thrive.
A 2010 study highlighted its powerful anti-stress effects, showing that clary sage oil could significantly alleviate symptoms of depression, further reducing stress-related impacts on hair health.
This oil may also enhance melanin production, improving the overall appearance of hair. To maximize these benefits, apply the diluted oil directly to the scalp, especially on areas experiencing thinning or irritation. Its soothing properties not only reduce inflammation but also encourage healthier hair growth.
Clary sage oil offers a well-rounded approach to managing PCOS-related hair loss, combining hormonal balance, anti-inflammatory effects, and scalp nourishment to support healthier, stronger hair.
Knowing the benefits of natural oils is just the beginning; applying them correctly is equally important to see results. Using the right techniques and staying consistent can make all the difference when addressing PCOS-related hair loss. Here's a step-by-step guide to help you get started.
Before trying any new oil, always do a patch test. Apply a small amount of diluted oil to your inner forearm or behind your ear. Wait 24 hours to see if there’s any irritation or reaction. This simple step can save you from potential discomfort.
Essential oils are potent and need to be diluted before use. Mix about 3–4 drops of your chosen essential oil with 1 tablespoon of a carrier oil, like coconut, jojoba, or olive oil. This ensures the oil is safe and effective for your scalp.
Scalp Massage
Warm up 1 tablespoon of oil and use your fingertips to massage it into your scalp in gentle, circular motions. This stimulates blood flow and helps the oil penetrate better.
Sectioning for Even Coverage
Divide your hair into sections to make sure the oil is evenly distributed. This method ensures no area is left untreated.
For the best results, apply the oil consistently before you wash your hair. For example, massaging warm jojoba oil into your scalp before shampooing is a widely recommended practice.
After letting the oil sit for the desired time, wash it out with a mild shampoo. Proper removal is important to avoid buildup and keep your scalp healthy.
Consistency is crucial. Studies have shown that regular application of oils can improve hair growth over time. Stick to your routine to see noticeable results.
If you’re new to using oils, start with one type at a time. Once you’re confident about how your scalp reacts, you can experiment with combining different oils for added benefits.
Keep a simple log of your oil treatments and take photos of your scalp periodically. This can help you monitor improvements and adjust your routine as needed.
Choosing the right oil for your PCOS-related hair concerns starts with understanding the benefits and potential downsides of each option. Here's a breakdown to help guide your decision:
| Oil | Benefits | Drawbacks | Best For |
|---|---|---|---|
| Coconut Oil | Absorbs well compared to mineral oils, fights scalp infections, may reduce hair fall, protects against heat damage, and adds hydration and shine | Overuse can lead to greasy hair and clogged pores | Dry hair, split ends, heat protection, and overall scalp health |
| Castor Oil | Stimulates hair follicles, improves circulation, has anti-inflammatory properties, and supports healthy hair growth | Thick texture requires dilution and may cause scalp buildup or irritation | Thinning hair, encouraging new growth, and improving circulation |
| Rosemary Oil | Helps remove excess oil, has antifungal properties, and may aid in hair loss prevention | Must be diluted and may irritate skin if used undiluted | Oily scalps and dandruff-prone hair |
| Pumpkin Seed Oil | May promote hair health, though evidence specific to PCOS is limited | Research on its effectiveness for PCOS-related hair loss is limited | Those curious about alternative options |
| Saw Palmetto Oil | May assist with hormone-related hair loss and is gaining popularity in hair care routines | Can interact with medications, and research on its topical benefits is limited | Androgenic alopecia and hormonal thinning |
| Lavender Oil | Known for its calming aroma and soothing effects on the scalp | Requires dilution and may cause allergic reactions | Scalp soothing (evidence for PCOS-related hair loss is minimal) |
| Clary Sage Oil | Traditionally thought to support hormonal balance, though research is scarce | Must be diluted, avoided during pregnancy, and may cause skin sensitivity | Gentle hormonal support (not recommended during pregnancy) |
Coconut oil stands out for its ability to hydrate and protect hair but should be used in moderation to avoid buildup. Castor oil can improve circulation and encourage growth but needs to be diluted to prevent scalp issues. Essential oils like rosemary, lavender, and clary sage require careful handling, as they must always be diluted to avoid skin irritation.
Pumpkin seed oil and saw palmetto oil show potential for addressing hormone-related hair loss, but their effectiveness for PCOS-specific concerns remains under-researched. Timing also plays a role, as PCOS-related dandruff affects about 50% of individuals at some point, and hormonal imbalances can make treatment more challenging.

After using natural oils and observing your scalp's response, it's important to know when to seek professional help. While natural oils can be beneficial for managing PCOS-related hair issues, worsening symptoms may signal the need for medical attention. Acting promptly can prevent further damage and improve your chances of effective treatment.
Warning signs to watch for include burning, itching, or any other discomfort on your scalp. Carolyn Trieu, PA at Franciscan Health, emphasizes the importance of addressing these symptoms:
"These symptoms may be a sign that inflammation or an infection is contributing to your hair loss. If you let inflammation go on long enough without proper treatment, it can lead to permanent hair loss."
Sudden or severe hair loss, as well as the appearance of round bald patches, should prompt an immediate consultation. These could indicate conditions like alopecia areata rather than PCOS-related thinning. Similarly, if you’re shedding more hair than usual or noticing a receding hairline, it’s time to consult a doctor.
Early intervention is key. If natural remedies haven’t shown noticeable improvement after consistent use, seeking professional care is a wise step. Starting treatment early increases the likelihood of hair regrowth and prevents further complications.
PCOS-related symptoms that occur alongside hair loss - such as irregular periods, difficulty conceiving, excessive hair growth, weight gain, oily skin, or acne - should also prompt a medical evaluation. These signs often point to hormonal imbalances that require specialized care.
For hair loss concerns, a dermatologist is often the best place to start. Dermatologists specialize in diagnosing and treating conditions affecting the skin, hair, and nails. Look for one with experience in managing hair loss disorders and knowledge of medical therapies.
If hormonal imbalances are suspected, an endocrinologist may be involved. Endocrinologists focus on the hormonal factors contributing to PCOS-related hair loss. Often, dermatologists and endocrinologists work together to ensure comprehensive care.
Dr. Armand Newman highlights the importance of this collaborative approach:
"Most of the patients will be picked up by the gynecologist and the gynecologist can help them a lot with their insulin resistance, with their infertility, and with their diet and exercise but I still think that the acne, hair loss, and hirsutism is just better treated with a dermatologist in this thing."
Combining dermatological and hormonal expertise ensures thorough treatment of both the root causes and visible symptoms of PCOS-related hair loss. This team-based approach can significantly improve both your scalp health and overall well-being.
If natural remedies aren’t yielding results or your hair loss feels concerning, don’t hesitate to seek professional help. Early action with the right specialists can make a big difference in preserving your hair health and addressing underlying issues effectively.
Natural oils provide a promising approach for managing PCOS-related hair loss while supporting scalp health. Research highlights that rosemary oil can be as effective as minoxidil, and pumpkin seed oil has been shown to increase hair count by 40% over several months.
These oils work by enhancing blood circulation and reducing DHT conversion, two key factors in promoting hair growth. Beyond hair growth, essential oils like lavender also offer anti-inflammatory properties, which can help calm irritated skin and may even reduce stress levels.
Consistency is the key to seeing results. Clinical studies indicate that these benefits often take several months of regular use. A simple way to start is by adding a few drops of rosemary oil to your shampoo or gently massaging diluted oils into your scalp two to three times a week. Sticking to this routine can help you achieve noticeable, long-term improvements.

The secret? Stick with it. Consistent application and gentle scalp massages can make a big difference over time. Patience pays off!
For those with sensitive scalps or skin conditions like eczema, tea tree oil and chamomile oil can work wonders thanks to their calming and anti-inflammatory effects. Another option to consider is coconut oil, which naturally moisturizes and helps combat dryness and irritation. Just remember to do a patch test beforehand to make sure the oil is compatible with your skin.
There’s nothing to indicate that natural oils like coconut oil or castor oil interfere with PCOS medications or treatments. These oils are typically safe for topical use and can be a helpful addition to your scalp care and hair routines. That said, if you're taking specific medications or undergoing treatments, it’s wise to consult your healthcare provider before trying new remedies. This way, you can make sure they fit seamlessly into your overall treatment plan and address your unique needs.
