Hirsutism affects 5% to 10% of women of childbearing age, leading to dark, coarse hair in areas like the face, chest, and back. It's often caused by hormonal imbalances, like those linked to PCOS (responsible for 70–80% of cases). Managing hirsutism can improve both physical symptoms and emotional well-being.
Key Medical Treatments for Hirsutism:
- Eflornithine Cream: Slows facial hair growth (results in 6–8 weeks).
- Oral Spironolactone: Reduces androgen levels for systemic results (6+ months).
- Topical Spironolactone: Targets hair locally with fewer side effects (6+ months).
- Combined Oral Contraceptives: Balances hormones and regulates cycles (up to 6 months).
- Laser Hair Removal: Long-term hair reduction (up to 90% reduction).

How Medical Treatments Reduce Unwanted Hair Growth
Medical treatments for hirsutism focus on addressing the hormonal imbalance that drives excessive hair growth. By lowering androgen levels and reducing the hair follicle's sensitivity to these hormones, these treatments provide a longer-term solution compared to temporary hair removal methods. The role of androgens in this condition is explored in greater detail in the next section.
Studies show that spironolactone has been effective in improving symptoms for 80% of hirsutism patients who used it consistently for 3 to 4 years. Side effects were reported in less than 5% of cases. Spironolactone works by lowering plasma testosterone levels through several mechanisms: reducing its production, converting it to estradiol, and blocking its binding to receptors in the skin.
Other medical options include oral contraceptives, which reduce androgen levels, regulate menstrual cycles, and prevent pregnancy. Anti-androgen medications prevent androgens from binding to their receptors, while eflornithine cream slows the growth of new hair but does not affect existing hair. These treatments work gradually, often taking weeks or even months to show noticeable results. The primary goal is to slow hair growth and reduce its density, rather than achieving complete hair removal.
How Androgens Cause Hirsutism
Androgens play a central role in hirsutism by transforming fine, light-colored vellus hair into coarse, dark terminal hair. They enlarge hair follicles and extend the anagen (growth) phase of the hair cycle.
The interaction between androgens and hair follicles is influenced by several factors. Free testosterone, the most active form of androgen, is the primary driver of this transformation. Inside hair follicles, specific enzymes - such as cytochrome P450 aromatase, 17β-hydroxysteroid dehydrogenase (17β-HSD), and 5α-reductase - regulate local androgen activity. This explains why the severity of hirsutism often depends more on the follicle's sensitivity to androgens than on the overall levels of circulating hormones. For example, most women with androgen levels exceeding twice the normal range experience some degree of hirsutism, though individual sensitivity varies.
Understanding these mechanisms underscores the importance of early, targeted treatment. Once terminal hair growth is established, reversing it becomes far more difficult, making timely intervention essential.
Modified Ferriman-Gallwey Score
The Modified Ferriman-Gallwey Score is the standard tool used to measure the severity of hirsutism and monitor treatment progress. This scoring system evaluates hair growth in nine areas: the upper lip, chin, chest, upper abdomen, lower abdomen, upper arms, thighs, upper back, and lower back.
Each area is scored from 0 (no terminal hair) to 4 (extensive terminal hair growth). A total score of 8 or higher is typically considered indicative of hirsutism, though this threshold can vary depending on ethnicity and individual factors. Healthcare providers use this score to decide if treatment is needed and to track how well it’s working over time.
The scoring system also helps set realistic expectations. Medical treatments aim to slow hair growth and reduce its density rather than eliminate it entirely. Regular assessments using the Modified Ferriman-Gallwey Score allow providers to adjust treatments or dosages as necessary, while also giving patients clear evidence of progress. This approach ensures that treatment plans are tailored to the individual’s specific needs and circumstances.
Medical Drugs That Treat Hirsutism
These medications work by targeting the pathways responsible for excessive hair growth, addressing the root causes of hirsutism. Below, we explore some common treatment options, their mechanisms, and how they can be used effectively.
Eflornithine Cream
Eflornithine cream slows hair growth by blocking an enzyme called ornithine decarboxylase, which plays a role in hair production.
Clinical studies have shown that after 24 weeks of use, 35% of participants experienced a noticeable reduction in facial hair growth, compared to just 9% in the placebo group. Initial improvements often appear within 4–8 weeks of consistent use. However, once treatment stops, hair growth typically returns to its original levels within about 8 weeks.
To use the cream, apply a thin layer to affected areas on the face and chin twice daily, spacing applications at least 8 hours apart. Avoid washing the treated area for at least 4 hours after application, and let the cream dry before applying makeup or sunscreen. If irritation occurs, reduce application to once daily.
For enhanced results, combining eflornithine with laser hair removal is a recommended approach. While the FDA-approved brand Vaniqa is no longer available in the U.S., compounded versions of eflornithine cream are still accessible through specialty pharmacies. Visit the Eflornithine page for more details.
Oral and Topical Spironolactone
Spironolactone offers both systemic and localized solutions for managing hirsutism, depending on the formulation.
- Oral spironolactone: This systemic treatment regulates hormone levels throughout the body and is effective for moderate to severe hirsutism. It reduces unwanted hair growth by targeting androgen activity.
- Topical spironolactone: This localized option minimizes side effects while providing targeted treatment. In one study, participants reported 100% satisfaction when comparing topical spironolactone to topical finasteride, with fewer side effects observed.
Both forms require a prescription and work by reducing androgen activity. Oral spironolactone can cause side effects such as menstrual irregularities (7.9%), dizziness or headaches (6.5%), and facial hypertrichosis (4.1%). Topical spironolactone, on the other hand, may cause mild skin irritation but avoids systemic side effects.
For more information, check out the Oral Spironolactone and Topical Spironolactone pages.
Oral Minoxidil
Oral minoxidil is known for its ability to promote hair growth, which can complicate its use for hirsutism. Hypertrichosis, or excessive hair growth, is its most common side effect.
Studies have found that hypertrichosis affects 10–25% of patients taking low doses (less than 4 mg) and up to 50% of those on higher doses (over 5 mg). Among women, 20% reported this side effect, though only 5% stopped treatment because of it.
Given the high risk of unwanted hair growth, oral minoxidil is generally better suited for treating scalp hair loss. For hirsutism, other antiandrogen therapies like spironolactone, cyproterone acetate, flutamide, or bicalutamide are often more appropriate. Learn more on the Oral Minoxidil page.
Combined Oral Contraceptives
Combined oral contraceptives are a common first-line treatment for hirsutism, offering the dual benefits of managing unwanted hair growth and providing contraception. These medications work by suppressing luteinizing hormone (LH) and follicle-stimulating hormone (FSH), which reduces ovarian androgen production. They also increase sex hormone-binding globulin (SHBG), lowering the amount of free testosterone that can stimulate hair follicles.
This treatment is particularly helpful for women with PCOS, as it can also regulate menstrual cycles and reduce acne. Healthcare providers can tailor contraceptive options based on your medical history and treatment goals, ensuring the best fit for your needs. Combined oral contraceptives can be evaluated alongside other therapies to create a comprehensive treatment plan.

Eflornithine cream is unique as the only topical treatment specifically formulated for facial hair. It works by slowing new hair growth but does not remove existing hair. For those needing broader hormonal regulation, spironolactone is available in both oral and topical forms. The oral version addresses systemic issues and typically shows results after at least six months of use. Studies suggest that longer treatment durations yield more noticeable improvements.
Oral minoxidil, on the other hand, is not recommended for hirsutism. In fact, it can worsen unwanted hair growth due to its high rates of hypertrichosis. Meanwhile, combined oral contraceptives are particularly effective for women dealing with PCOS, which accounts for 70–80% of hirsutism cases. These contraceptives not only help regulate hormones but also provide the added benefit of contraception.
"Laser hair removal is the most effective, long-term treatment for hirsutism with additional support of medications, supplements, and changes in diet." – Dr. Rasya Dixit
For optimal results, many patients combine treatments. For instance, eflornithine cream can offer quick cosmetic improvements for facial hair while oral spironolactone works on long-term hormonal regulation. Laser hair removal is often added to the mix, as it can reduce hair growth by up to 90%.
Cost considerations also play a role in treatment selection. While some options are more affordable, others may offer targeted or systemic benefits that justify their price. Ultimately, the right choice depends on whether you’re looking for localized hair reduction or broader hormonal control.
How to Choose the Right Treatment for You
Selecting a treatment for hirsutism depends on your specific symptoms, overall health, and personal goals. Here's what to keep in mind as you navigate your options:
Understand the severity of your condition. While the Ferriman-Gallwey score can help measure the extent of hair growth, what truly matters is how much the condition affects you emotionally. According to the Endocrine Society, treatment should focus on "patient-important hirsutism", meaning hair growth that causes you distress, regardless of clinical scores. If methods like shaving, plucking, or waxing are enough to manage your symptoms, medical treatments might not be necessary. This self-assessment is an important starting point for choosing a treatment plan.
Factor in your reproductive plans. If you're trying to conceive or may become pregnant, certain medications, like spironolactone, should be avoided due to potential risks to a developing fetus. For women not planning a pregnancy and who find cosmetic measures insufficient, combined oral contraceptives are often the first-line treatment.
Address underlying health conditions. If you have polycystic ovary syndrome (PCOS), managing it can sometimes reduce hair growth. Additionally, if you're overweight or obese, your doctor may suggest lifestyle changes and weight loss to help naturally lower androgen levels.
Consider your treatment preferences. Some women prefer topical treatments to avoid the systemic effects of oral medications. For example, eflornithine cream is a good option for slowing hair growth and can be paired with other treatments for better results.
Set realistic timeline expectations. Most medications take about six months to show noticeable improvement. If you're looking for quicker results, combining treatments may help. For instance, you could use eflornithine cream to slow hair growth immediately while starting spironolactone for longer-term hormonal regulation.
Review your budget and insurance coverage. Costs for treatments can vary widely. Combined oral contraceptives are often covered by insurance, making them a more affordable option for many patients.
Acknowledge the emotional impact. Hirsutism can significantly affect self-esteem and quality of life. It's important to discuss these concerns with your healthcare provider.
Explore combination approaches. A mix of systemic therapy and hair removal methods often yields the best results. For example, laser therapy can reduce unwanted hair while also helping to alleviate feelings of anxiety or depression.
Know when to seek specialized care. If your case is difficult to manage, your doctor might refer you to a dermatologist for advanced options. For hair types that don't respond well to laser treatments, such as blonde or white hair, electrolysis may be recommended.
Consult a licensed medical professional. Hirsutism can sometimes signal underlying conditions like PCOS, Cushing syndrome, or congenital adrenal hyperplasia. A thorough medical evaluation is crucial to identify the root cause, assess risk factors, and monitor for side effects during treatment [3, 47, 48].
For personalized guidance, consider platforms like Oana Health. Their telehealth services allow licensed professionals to review your health history and recommend tailored treatments. With options like oral spironolactone, topical spironolactone, and eflornithine cream, you can access science-backed solutions delivered directly to your home without frequent office visits.
It's important to note that while current systemic therapies can help manage hirsutism, none are FDA-approved specifically for this condition. Expert guidance is key to ensuring safe and effective treatment.
Conclusion: Key Points About Medical Treatments for Hirsutism
Medical treatments for hirsutism provide meaningful options for the 5% to 10% of women affected by this condition. Effective management involves a well-rounded approach that includes hormonal regulation, targeted therapies, and setting realistic expectations.
Dr. N K Agrawal from the Department of Endocrinology and Metabolism at Banaras Hindu University highlights that a thorough evaluation combined with a mix of therapies - such as hormonal treatments paired with hair removal techniques - can lead to positive results for most patients. Common strategies include suppressing androgens, blocking their effects, and incorporating hair removal methods. For instance, combining oral contraceptives to regulate hormones with topical treatments like eflornithine cream - or using spironolactone alongside laser therapy - can significantly improve outcomes.
Treatment takes time. Many medical therapies require at least six months to show noticeable results due to the natural hair growth cycle. For example, eflornithine cream has shown improvement in 60% of patients after consistent use for six months.
Addressing root causes is essential. With more than 70% of hirsutism cases linked to PCOS, managing this condition often leads to better hair growth patterns. Even a modest weight loss of 5% can greatly improve PCOS-related symptoms. This highlights the importance of creating tailored treatment plans for each individual.
Personalized care matters. The Endocrine Society advises focusing on "patient-important hirsutism", meaning hair growth that causes distress, regardless of its clinical severity.
Improved access to treatment: Platforms like Oana Health make expert evaluations and customized treatment plans more accessible. Licensed professionals can review your health history and prescribe treatments such as oral spironolactone, topical spironolactone, and eflornithine cream, delivering scientifically-backed solutions straight to your door.
FAQs
What’s the difference between oral and topical spironolactone for treating hirsutism?
Oral spironolactone works throughout the body to lower hormone levels that play a role in hirsutism, making it a suitable choice for addressing more extensive hair growth. That said, it can lead to systemic side effects, such as dizziness or shifts in potassium levels.
Topical spironolactone, in contrast, is applied directly to the skin to treat specific areas like the face. This approach reduces the risk of systemic side effects while effectively managing unwanted hair in smaller, targeted spots.
How do birth control pills help reduce unwanted hair growth in women with PCOS?
Birth control pills, often referred to as combined oral contraceptives (COCs), are a reliable option for managing unwanted hair growth, or hirsutism, associated with PCOS. These pills work by lowering the levels of free androgens - hormones that play a key role in excessive hair growth. They do this by boosting the production of sex hormone-binding globulin (SHBG), a protein that binds to testosterone and reduces its activity in the body.
In addition to this, COCs also suppress the ovaries' production of androgens, further cutting down the hormone levels responsible for hirsutism. Over time, this dual action helps reduce excessive facial and body hair, making COCs a popular and effective first-line treatment for women with PCOS dealing with hirsutism.
Why is laser hair removal often used with medications to treat hirsutism?
Laser hair removal is often paired with medications to manage hirsutism because it tackles visible hair growth more efficiently. While medications like anti-androgens work to address the hormonal triggers behind hirsutism, laser treatments target and reduce existing hair, providing a longer-lasting solution for unwanted facial and body hair.
This dual approach delivers better results by addressing both the underlying cause and the cosmetic concerns of excess hair. It’s an effective option for those looking for a more thorough way to manage hirsutism and boost their self-confidence.
