PCOS and Hair Loss: Hormonal Testing Explained

Hair loss is a common and distressing symptom of PCOS (Polycystic Ovary Syndrome), affecting up to 70% of women with the condition. The root cause lies in hormonal imbalances, particularly elevated androgens like testosterone and DHT, which disrupt hair growth. Early detection and treatment can help slow hair loss and even promote regrowth.

Key Points:

• PCOS Basics: Affects 6–13% of U.S. women, often causing irregular periods, high androgens, and insulin resistance.
• Hair Loss Symptoms: Gradual thinning at the crown, widening part line, and increased hair shedding.
• Hormones Involved: Elevated testosterone, DHT, and low SHBG levels are primary contributors.
• Testing: Comprehensive hormone panels (testosterone, DHEA-S, LH:FSH ratio, SHBG, AMH) help diagnose PCOS and pinpoint causes of hair loss.
• Treatment Options:
  • Medications: Spironolactone, minoxidil (oral or topical), and metformin.
  • Lifestyle Changes: Weight loss, balanced diet (e.g., Mediterranean), exercise, and stress management.
  • Hair Care: Use gentle products, avoid heat styling, and prevent breakage.

Take Action: If you notice hair thinning or shedding, consult a healthcare provider for testing and treatment. Early intervention improves outcomes and supports hair regrowth.

Hormones, PCOS, and Hair Loss

Hormonal Imbalances That Cause Hair Loss in PCOS

PCOS disrupts the delicate balance of hormones, impairing hair follicle function and leading to thinning hair.

Hormones Behind Hair Loss in PCOS

Androgens play a major role in PCOS-related hair loss. While hormones like testosterone are naturally present in women, elevated levels - common in PCOS - can overstimulate hair follicles. Research shows that up to 89% of patients with hyperandrogenemia have heightened levels of free testosterone.

Testosterone can convert into dihydrotestosterone (DHT), which binds to hair follicles, causing them to shrink and triggering androgenetic alopecia.

Sex hormone-binding globulin (SHBG) usually regulates testosterone by binding to it and limiting its activity. In women with PCOS, SHBG levels are often lower, leaving more free testosterone to act on hair follicles. Additionally, higher levels of anti-Müllerian hormone (AMH) in PCOS can further increase free testosterone exposure. Insulin resistance, another common feature of PCOS, can worsen this imbalance by driving up testosterone levels even more, creating a vicious cycle of hormonal disruptions and hair loss.

The Role of LH:FSH Ratio in Hair Loss

Hormonal imbalances in PCOS go beyond elevated androgens. The ratio of luteinizing hormone (LH) to follicle-stimulating hormone (FSH) also plays a role. Studies indicate that lean women with PCOS tend to have a higher LH/FSH ratio compared to those who are obese. This imbalance stems from disrupted gonadotropin-releasing hormone (GnRH) pulses in the brain, which stimulate ovarian theca cells to produce more androgens. This cascade not only interferes with normal follicle development but also intensifies hair thinning. These hormonal patterns are part of the Rotterdam criteria used to diagnose PCOS.

Diagnosing PCOS with the Rotterdam Criteria

The internationally recognized Rotterdam Criteria diagnose PCOS by identifying at least two of three key features: irregular ovulation, hyperandrogenism, and polycystic ovarian morphology visible on ultrasound. Clinical signs of elevated androgens include hirsutism, acne, and female pattern hair loss. Hirsutism affects 60–70% of women with PCOS, while androgenetic alopecia impacts 40–70% of young women with the condition. These symptoms provide visible clues to deeper hormonal imbalances.

Importantly, a PCOS diagnosis can still be made under the Rotterdam framework even if polycystic ovaries aren't detected on an ultrasound. For instance, hair loss combined with irregular menstrual cycles may indicate hyperandrogenism, meeting the diagnostic criteria. This approach has helped many women receive accurate diagnoses and begin appropriate treatments. However, it's crucial to rule out other conditions that mimic PCOS symptoms, such as thyroid disorders or nutritional deficiencies. Comprehensive testing ensures effective diagnosis and tailored treatment plans.

Hormonal Tests for PCOS and Hair Loss Diagnosis

Hormonal testing plays a crucial role in diagnosing PCOS and understanding hair loss. With an estimated 70% of PCOS cases going undiagnosed, these tests are essential for identifying the condition and creating effective treatment plans.

Required Hormonal Tests

A comprehensive PCOS hormone panel typically includes 10 tests that evaluate hormonal function and pinpoint imbalances contributing to hair loss.

• Testosterone Testing: Measures both total and free testosterone levels. Elevated androgen levels are common in 60%–80% of women with PCOS. Free testosterone, the active form, directly interacts with hair follicles, impacting hair growth.
• DHEA-S (Dehydroepiandrosterone Sulfate): Assesses adrenal androgen production. High levels suggest adrenal overactivity, which can worsen hair loss.
• LH and FSH Testing: Tracks luteinizing hormone (LH) and follicle-stimulating hormone (FSH). An altered LH:FSH ratio often indicates increased ovarian androgen production.
• SHBG (Sex Hormone-Binding Globulin): This protein binds testosterone. Lower SHBG levels mean more free testosterone, increasing the risk of hair loss.
• AMH (Anti-Müllerian Hormone): Often elevated in PCOS, high AMH levels provide insights into ovarian function and are linked to higher androgen exposure.

Other tests may include prolactin (to rule out pituitary issues), TSH (to check thyroid function), estradiol (for overall hormonal balance), and 17-alpha-hydroxyprogesterone (to screen for other hormonal conditions).

How to Read Your Test Results

Interpreting hormone test results isn’t about individual values - it’s about seeing the bigger picture. Healthcare providers consider your symptoms, medical history, and overall hormonal profile to make an accurate diagnosis.

For women with regular cycles, testing is typically done on day 3 of the menstrual cycle (day 1 being the first day of your period). If your cycles are irregular or absent, testing can be done at any time, although timing may influence the results. Avoid taking biotin for at least 72 hours before testing, as it can interfere with lab results.

It’s important to review your results with a healthcare professional who can analyze the complete hormonal pattern in the context of your overall health. These results lay the foundation for personalized treatment, which will be covered in the next section.

Treatment Options for PCOS Hair Loss

Addressing PCOS-related hair loss requires a combination of tackling hormonal imbalances and managing visible hair thinning. Based on test results, treatments are tailored to target the hormonal shifts causing the issue. Here’s a look at some proven approaches that can help slow hair loss and even encourage regrowth.

Prescription Medications for Hair Loss

One of the most effective options for PCOS hair loss is spironolactone, an anti-androgen medication that lowers androgen levels, directly addressing the root cause of the problem. Research shows that spironolactone alone can improve hair loss in 43% of cases, but when combined with minoxidil, success rates jump to 75%.

For those who prefer simplicity, oral minoxidil offers an easier-to-use alternative to its topical counterpart, often being better tolerated and less messy. When paired with spironolactone, results can be even more promising. A 2018 study involving 100 women taking a daily capsule containing spironolactone (25 mg) and minoxidil (0.25 mg) for a year showed consistent improvements in both hair shedding and density at intervals of 3, 6, 9, and 12 months.

"Minoxidil-spironolactone could be considered as an effective treatment to improve AGA, female, and male hair loss patterns. Overall, treatment with minoxidil-spironolactone was better than treatment with minoxidil-finasteride for the female and male patterns of AGA." - Bazargan et al

For those who want a more localized solution, topical spironolactone is an option. It delivers anti-androgen effects directly to the scalp, minimizing the risk of systemic side effects.

If you’re looking for personalized care, telehealth platforms like Oana Health offer tailored treatment plans. They provide access to medications like oral minoxidil ($25/month) and topical spironolactone ($43/month), designed to fit individual hormonal profiles and needs.

It’s important to note that women who are pregnant or nursing should consult their doctor before starting these treatments. Additionally, regular blood pressure monitoring is essential during spironolactone therapy.

Insulin-Sensitizing Medications

Since insulin resistance is a common issue in PCOS, addressing it can also support hair health. Metformin, a medication often used to manage insulin resistance, has shown potential in reducing PCOS-related hair loss. With 50% to 75% of individuals with PCOS experiencing insulin resistance, targeting this issue can have a noticeable impact on hair regrowth.

A 2016 clinical trial highlighted metformin's benefits, showing that it reduced hair loss in participants with PCOS. Metformin works by lowering blood sugar levels, reducing glucose production in the liver, and improving insulin sensitivity. In one study, researchers observed significant improvement in hair growth among women with PCOS taking metformin compared to a placebo group.

"We have demonstrated that metformin treatment in a group of women with PCOS results in a clinically and statistically significant improvement in hair growth compared with placebo."

The link between insulin and hair loss is clear: elevated insulin levels can trigger hair loss, even without high androgen levels. By addressing insulin resistance, metformin helps create an environment conducive to hair regrowth.

Specialized services like Oana Health provide access to oral metformin ER at $22/month or combination treatments like metformin with spironolactone at $32/month for a more comprehensive approach to hormonal balance.

One caution: if you notice hair loss while taking metformin, it’s worth discussing vitamin B-12 levels with your doctor. Metformin can sometimes lead to B-12 deficiency, which may contribute to hair issues.

Lifestyle Changes for Hair Health

While medications target the biochemical causes of PCOS hair loss, lifestyle adjustments lay the groundwork for sustainable results. These changes complement medical treatments, helping to balance hormones and support overall hair health.

Even a modest 5% weight loss can significantly improve PCOS symptoms, including hair loss. Following a Mediterranean diet, which emphasizes fiber and anti-inflammatory foods, can help lower insulin and androgen levels. Focus on foods like whole grains, leafy greens, nuts, olive oil, and fatty fish, while avoiding refined carbs, sugary drinks, fried foods, and processed meats. Aim for 21-25 grams of fiber daily to support hormonal health.

Incorporating regular exercise is equally important. Aim for 120 minutes of vigorous activity each week, combining aerobic and resistance training. Activities like brisk walking, swimming, biking, push-ups, and weight lifting can improve insulin sensitivity and hormonal balance. Stress-relieving practices like yoga, tai chi, or pilates can further support these efforts.

Sleep and stress management are crucial as well. Strive for 7-9 hours of quality sleep each night and consider stress-relief methods like meditation or therapy to maintain hormonal stability.

As Amanda Stathos, a Clinical Dietitian at Johns Hopkins' Sibley Memorial Hospital, explains:

"Not everyone with polycystic ovary disease has these complications, but for those who do, reaching and maintaining a healthy weight is our first concern, and that starts with diet and exercise."

Nutritional Therapist Angelique Panagos adds:

"Simply put, PCOS is an insulin and testosterone-driven condition... It can lead to weight gain, especially around the stomach area, and insulin resistance, which in turn can result in other health problems such as type 2 diabetes. But if you're willing to make lifestyle changes around how you eat, sleep and move then you can balance your blood sugar, increase your sensitivity to insulin and manage your symptoms, including your weight, effectively."

These lifestyle changes not only address hair loss but also reduce the risk of long-term complications. For example, over 50% of women with PCOS develop type 2 diabetes by age 40 if symptoms are left unmanaged. This makes a holistic approach to treatment essential for both immediate and future health benefits.

Preventing and Managing PCOS Hair Loss

Addressing PCOS-related hair loss early can make a big difference. Studies show that 42.5% of women with PCOS experience androgenetic alopecia, compared to just 6% in the general population. The good news? Hair regrowth is possible if caught early. That’s why regular monitoring is crucial for women at risk.

Early Detection and Regular Testing

Spotting the first signs of hair loss can significantly improve treatment outcomes. Look out for subtle changes like more hair in your brush, a widening part, or changes in hair texture. These early warning signs often appear before noticeable thinning.

Testing plays a key role in understanding your risk. Hormonal tests - like those for total and free testosterone, androstenedione, DHT, and DHEA-S - can help pinpoint imbalances. If hair loss is a concern, testing your hormone levels is a smart first step.

Nutritional deficiencies can also worsen hair thinning. Baseline tests for micronutrients such as zinc, ferritin, and vitamin D can reveal gaps that might be contributing to the problem. Correcting these deficiencies through targeted supplementation can improve the effectiveness of your treatment plan.

Beyond annual check-ups, women with PCOS should regularly monitor their health to catch any related issues that could affect hair health. Once early signs are identified and test results are in, working with a professional to develop a personalized plan is the next step.

Getting Professional Medical Help

Addressing PCOS hair loss effectively means seeking expert guidance tailored to your unique hormonal profile and symptoms. A licensed healthcare provider can create a treatment plan that tackles both the root cause - hormonal imbalances - and the visible effects, like thinning hair.

When it comes to treatment options, professional advice is essential. Deciding between anti-androgen therapy, insulin-sensitizing medications, or a combination of approaches requires a thorough evaluation of your medical history and test results.

Services like Oana Health specialize in PCOS care, offering personalized evaluations and science-backed treatment plans. Their approach includes a comprehensive review of your health history, with recommendations delivered right to your home.

Specialized care ensures treatments are tailored to your needs. For instance, a provider might suggest pairing topical spironolactone ($43/month) with lifestyle adjustments or combining oral minoxidil ($25/month) with insulin-sensitizing therapies for a well-rounded approach.

Ongoing professional monitoring also ensures safety and effectiveness. For example, medications like spironolactone may require regular blood pressure checks, and your provider can adjust dosages or treatment combinations as needed. This personalized approach builds on early detection, ensuring your treatment evolves with your hormonal profile.

Long-Term Hair Health Strategies

Once you’ve started your treatment plan, consistency is key. PCOS-related hair loss can be managed by addressing the underlying hormonal imbalance, but maintaining progress requires dedication.

Stick to your prescribed treatments. Hair growth cycles take time - usually 3–6 months - to show visible results. Whether you’re using topical treatments, oral medications, or both, skipping doses or stopping too soon can undo your progress.

Support your treatment with healthy habits. Eat a balanced, nutrient-rich diet, stay active, and manage stress to help regulate your hormones. At the same time, practice gentle hair care to protect your existing hair. Use sulfate-free shampoos, limit heat styling with proper heat protectants, and avoid tight hairstyles that can lead to breakage. These steps are especially important during the early stages of treatment when your hair may be more fragile.

Regular follow-ups are just as important as starting treatment. Schedule appointments to monitor hormone levels, adjust medications if necessary, and address any new symptoms. This ongoing care ensures your treatment remains effective and prevents setbacks.

As Amanda Stathos, M.S., R.D., L.D.N., emphasizes:

"If you are diagnosed with polycystic ovary syndrome, it doesn't mean that you are destined to have poor health. There is a lot you can do to take charge, minimize symptoms and keep yourself healthy."

Incorporating a healthy lifestyle isn’t just about hair - it’s a comprehensive way to manage PCOS symptoms. By doing so, you can reduce risks like irregular periods and even long-term complications such as type 2 diabetes, which affects over 50% of women with PCOS by age 40 when left unmanaged.

Conclusion: Managing PCOS Hair Loss Successfully

Hair loss tied to PCOS impacts nearly 30% of women with the condition, but with the right approach, this challenging symptom can be addressed effectively.

The root of the issue often lies in elevated testosterone and DHT levels, which can shrink hair follicles and disrupt normal growth cycles. Tackling these hormonal imbalances is crucial - not just for hair health, but for overall well-being.

Comprehensive hormonal and nutritional testing, such as checking ferritin and zinc levels, plays a key role in identifying imbalances and shaping a treatment plan. Acting early can significantly improve the chances of regrowth.

For the best results, treatments often combine anti-androgens like spironolactone (available in both topical and oral forms) with hair growth therapies and insulin-sensitizing medications. Providers like Oana Health offer affordable options, including spironolactone for $14/month, topical spironolactone for $43/month, and oral minoxidil for $25/month. These treatments, paired with expert guidance, are tailored to meet individual hormonal profiles.

Consistency is key. With a dedicated regimen and lifestyle changes, noticeable hair regrowth can often be seen within six to twelve months. By combining detailed testing, targeted treatments, and healthy habits, you can address the underlying causes of PCOS hair loss and take meaningful steps toward restoring both your hair and confidence.

FAQs

How can I tell if my hair loss is caused by PCOS or something else?

Hair loss associated with Polycystic Ovary Syndrome (PCOS) is often tied to hormonal imbalances, especially higher levels of androgens. Signs to watch for include thinning hair on the scalp, increased facial hair growth (hirsutism), irregular menstrual cycles, and weight gain. These symptoms often suggest PCOS as a possible underlying factor.

To diagnose PCOS, a healthcare provider might perform a physical exam to check for signs like acne or excess hair growth. They may also order blood tests to evaluate hormone levels and, in some cases, recommend an ultrasound to detect ovarian cysts. If PCOS is ruled out, the provider can investigate other potential reasons for hair loss, such as thyroid problems or nutritional deficiencies.

What are the best ways to treat hair loss caused by PCOS?

Managing hair loss linked to PCOS often requires a mix of medical treatments and lifestyle adjustments to tackle the hormonal imbalance at its core. On the medical side, options like spironolactone - which helps minimize the effects of androgens on hair follicles - and minoxidil, a topical treatment that encourages hair regrowth, are commonly used.

Lifestyle changes can make a big difference too. Shedding even a small amount of weight has been shown to lower androgen levels, which may help reduce hair loss. Pairing a nutrient-rich diet with regular physical activity can further promote hormonal balance and overall health.

For those looking for tailored solutions to manage PCOS-related hair loss, Oana Health provides treatments grounded in science, prescribed by licensed professionals, and conveniently delivered right to your doorstep.

Can diet and exercise help reduce hair loss caused by PCOS?

Yes, what you eat and how active you are can make a big difference when it comes to managing hair loss linked to PCOS. A diet packed with omega-3 fatty acids, antioxidants, and protein can strengthen your hair and help regulate the hormones that contribute to thinning. On top of that, switching to a low-carb diet might help tackle insulin resistance - a common PCOS challenge that can increase androgen levels and make hair loss worse.

Staying active is just as important. Regular exercise can boost insulin sensitivity, lower inflammation, and help balance hormones, all of which can support healthier hair growth. By combining a nutrient-rich diet with consistent physical activity, many women with PCOS find not only improvements in hair loss but also a boost in overall health and well-being.
