Hirsutism is more than just extra hair - it’s coarse, dark hair appearing in areas women typically don’t have much hair, like the face, chest, or abdomen. It’s often caused by hormonal imbalances, with PCOS accounting for 70%-80% of cases. Here’s how to distinguish it from normal hair growth:
- Normal Hair: Fine, light "peach fuzz" covering most of the body.
- Hirsutism: Thick, dark hair in male-pattern areas (upper lip, chin, chest, back, abdomen).
- Other Symptoms: Acne, irregular periods, thinning scalp hair, or deeper voice.
Quick Comparison
| Feature | Normal Hair Growth | Hirsutism |
|---|---|---|
| Texture & Color | Fine, light (vellus hair) | Coarse, dark (terminal hair) |
| Location | Scalp, underarms, legs | Face, chest, abdomen, back |
| Cause | Natural growth cycle | Hormonal imbalance (e.g., PCOS) |
| Additional Symptoms | None | Acne, irregular periods, virilization |
If you notice sudden or unusual hair growth in male-pattern areas, consult a doctor. Treatments like eflornithine cream or spironolactone can help, alongside lifestyle changes and cosmetic removal methods like laser therapy.

What Is Hirsutism?
Hirsutism refers to male-pattern hair growth in women, appearing on areas like the face, chest, back, and abdomen. It affects about 10% of women, though some studies suggest the number could be as high as 40%, depending on the degree of hair growth [12, 13, 5]. This condition is characterized by coarse, dark hair in areas typically associated with male-pattern hair growth.
"Hirsutism is an androgen-dependent disorder resulting from the interaction between circulating androgen levels and the sensitivity of the hair follicle to androgens." - Wissem Hafsi; Jasleen Kaur
The condition is triggered by either an overproduction of androgens - hormones like testosterone - or an increased sensitivity of hair follicles to these hormones. While androgens contribute to masculine traits such as facial and body hair, estrogen works to keep hair finer and lighter.
Hirsutism often points to an underlying hormonal imbalance. One of the most common causes is polycystic ovary syndrome (PCOS). In fact, up to 90% of women with hirsutism have hormonal imbalances, and 70%-80% of women with PCOS experience hirsutism [12, 5].
Main Features of Hirsutism
Hirsutism involves hair growth in areas sensitive to androgens, such as the upper lip, chin, chest, abdomen, and back. In these regions, androgens stimulate hair follicles to transform fine, light vellus hair into thick, dark terminal hair by prolonging its growth phase [13, 5, 10].
The severity of hirsutism varies. Some women may notice a few coarse hairs on their chin, while others experience widespread growth across multiple areas. To assess the extent of hair growth, healthcare providers often rely on the Ferriman-Gallwey scoring system.
Genetics and ethnicity also play a role in hirsutism. Women from Mediterranean, Middle Eastern, or South Asian backgrounds are naturally more likely to have darker, coarser body hair. This can sometimes blur the line between familial hirsutism (a genetic trait) and hormone-related hirsutism.
Hirsutism vs Hypertrichosis
Although both hirsutism and hypertrichosis involve excess hair growth, they are distinct conditions with different causes and treatment approaches.
Hirsutism refers specifically to male-pattern hair growth in women. It occurs in androgen-sensitive areas like the face, chest, and back and is directly tied to hormonal imbalances.
Hypertrichosis, on the other hand, involves increased hair growth anywhere on the body, regardless of gender or androgen sensitivity. It can result from factors like medication side effects, systemic illnesses, genetic conditions, or even as part of a paraneoplastic syndrome [16, 18].
"It is important to distinguish hypertrichosis from hirsutism, which is a term reserved for females who grow an excessive amount of terminal hairs in androgen-dependent sites." - Dahlia Saleh; Siva Naga S. Yarrarapu; Christopher Cook
This distinction is crucial because the underlying causes differ significantly. Hirsutism typically signals a hormonal imbalance that may require medical treatment, while hypertrichosis often stems from external factors or unrelated health conditions [17, 18].
Recognizing these differences helps ensure that you and your healthcare provider can identify the root cause and develop the most effective treatment plan if you’re dealing with excessive hair growth.
Normal Hair Growth in Women
Understanding typical hair growth patterns is essential for spotting irregularities. For women, around 30% of the body is covered with terminal hair - thicker and darker strands - found on areas like the scalp, underarms, pubic region, and legs. The remaining areas are covered by fine, lightly pigmented vellus hair, which is much less noticeable . This predictable distribution serves as a baseline for identifying unusual hair growth, such as that seen in hirsutism.
Shedding hair daily is completely normal. On average, a person loses about 100 hairs each day as part of the natural growth cycle.
How to Tell Hirsutism from Normal Hair Growth
The key to distinguishing hirsutism from normal hair growth lies in the texture, color, and location of the hair. Normal hair tends to be fine and light, while hirsutism is marked by thicker, darker hair in specific areas.
Hair Growth Pattern Differences
Normal hair, often referred to as vellus hair, is soft and barely noticeable. It typically appears on the face, arms, and torso as a light, peach-fuzz-like layer. In contrast, hirsutism is characterized by coarse, dark terminal hair that grows in areas sensitive to androgen hormones, such as the upper lip, chin, chest, lower abdomen, and back.
The distribution of hair in hirsutism follows a pattern more commonly seen in men, making it distinct from the finer, lighter growth associated with normal hair.
Other Symptoms That Come with Hirsutism
Hirsutism often comes with a set of additional symptoms, making it easier to identify. These symptoms are typically linked to hormonal imbalances, particularly elevated androgen levels.
Women with hirsutism may experience signs of virilization, such as acne, irregular menstrual cycles, and thinning hair at the temples. In more severe cases, symptoms can include a deeper voice, balding, a decrease in breast size, increased muscle mass, and clitoral enlargement. These changes often point to underlying conditions like polycystic ovary syndrome (PCOS), which is a frequent cause of hirsutism.
The Ferriman-Gallwey Scoring System
To assess hirsutism objectively, healthcare providers use the Ferriman-Gallwey Scoring System. This method evaluates hair growth in nine androgen-sensitive areas, assigning a score from 0 (no hair) to 4 (extensive hair) for each region. The total score determines the severity of hirsutism.
- A score above 8 typically indicates hirsutism and the need for further medical evaluation.
- Scores between 8 and 15 suggest mild hirsutism.
- Scores above 15 point to moderate to severe cases.
This scoring system is particularly helpful because hirsutism affects 5% to 10% of women of childbearing age. It also distinguishes androgen-related hair growth from conditions like hypertrichosis, which involves excessive hair growth that isn't influenced by androgen levels.

What Causes Hirsutism and Risk Factors
Hirsutism often results from hormonal imbalances, particularly elevated levels of androgens like testosterone and androstenedione.
"Hirsutism is the presence of excess male-pattern hair growth in women and is commonly caused by an imbalance of hormones." - Yourhormones.info
The condition is influenced not just by hormone levels but also by how sensitive hair follicles are to these hormones. Factors like follicle sensitivity, local hormone conversion, and the duration of hormone exposure all play a role in turning fine, soft vellus hairs into thicker, coarser terminal hairs.
Hormonal Issues and PCOS
Polycystic Ovary Syndrome (PCOS) is the leading cause of hirsutism, affecting most women diagnosed with the condition.
PCOS creates an environment where androgen levels rise significantly, leading to the transformation of fine vellus hairs into thick terminal hairs in areas sensitive to these hormones, such as the face, chest, and abdomen.
"Hirsutism in PCOS is associated with both androgen excess and individual response of the pilosebaceous unit to androgens." - Poli Mara Spritzer
Insulin resistance, often linked to PCOS, further amplifies androgen production, worsening hirsutism. Studies show that 70% to 80% of individuals with PCOS experience hirsutism.
Additional Causes and Risk Factors
Though PCOS is the primary driver, other factors can also lead to excessive hair growth. Idiopathic hirsutism, where no specific cause is identified, accounts for about 10% of all cases and half of mild cases.
Rarely, androgen-secreting tumors are to blame, though these account for only about 0.2% of cases. Other medical conditions, like Cushing syndrome and congenital adrenal hyperplasia, can also contribute through different hormonal mechanisms.
Genetics and ethnicity play a role as well. Women of Mediterranean, Middle Eastern, and South Asian descent are more likely to develop hirsutism. Obesity can exacerbate the problem by increasing insulin resistance and boosting androgen levels, which can further disrupt hormonal balance. Additionally, certain medications may list hirsutism as a side effect.
Understanding these risk factors is crucial in addressing and managing the condition effectively.
When to Consult a Doctor
Sudden or rapid hair growth, particularly when accompanied by signs of virilization, calls for immediate medical attention. Symptoms like irregular periods, severe acne, voice deepening, or male-pattern baldness may signal a serious hormonal imbalance requiring evaluation.
Emotional distress from unwanted hair growth is another valid reason to seek help. Hirsutism can significantly affect self-esteem and quality of life. For those trying to conceive, addressing the condition is especially important, as the underlying hormonal imbalances can interfere with ovulation and fertility.
If you notice these symptoms, consulting a healthcare provider can help pinpoint the cause and guide you toward the right treatment options. Early intervention makes a significant difference and sets the stage for managing the condition effectively.
Treatment Options for Hirsutism
Managing hirsutism often involves a mix of medical treatments and cosmetic approaches. While medications can address the underlying causes, hair removal techniques help manage visible hair. It’s important to note that most medical treatments require time - around six months - to show noticeable changes due to the natural growth cycle of hair follicles. Combining methods often provides the most effective results.
Prescription Medications
Several prescription options are available to help reduce hair growth and manage hirsutism effectively:
- Eflornithine Cream: This topical treatment is specifically designed for facial hair. It works by inhibiting the enzyme ornithine decarboxylase, which slows the growth of new, thicker hair. Applied twice daily, it doesn’t remove existing hair but helps reduce the appearance of new growth over time. Studies show that 60% of patients see improvement after six months of use. According to Drugs.com, Vaniqa (a brand of eflornithine) has a user rating of 7.2 out of 10, with 68% reporting positive effects. Common side effects include mild acne (8.1%), temporary hair loss (4.5%), and dry skin (3.6%).
- Spironolactone: Taken orally, this medication blocks androgen receptors, reducing the effects of androgens that contribute to excessive hair growth. It’s often prescribed when oral contraceptives don’t provide sufficient results. However, spironolactone may cause menstrual irregularities and requires concurrent contraception due to the risk of birth defects. User reviews rate it at 6.9 out of 10, with 58% reporting positive outcomes. Side effects include acne (11.4%), dizziness (8.0%), and hair loss (7.1%).
- Topical Spironolactone: For those who want to avoid systemic side effects, topical spironolactone is an option. Available through Oana Health, this formulation targets specific areas, reducing overall exposure to the medication.
Combination therapies can also be effective. Research shows that combining treatments can reduce hirsutism scores by 49% after 12 months, compared to 45% for flutamide alone and 32% for finasteride alone.
Oana Health simplifies access to both eflornithine and spironolactone with home delivery, making it easier for women to manage hirsutism. Pairing these medications with cosmetic hair removal often leads to the best results.
Lifestyle Changes and Hair Removal
In addition to medications, lifestyle adjustments and cosmetic treatments play an important role in managing hirsutism. For women with PCOS, weight management can be particularly beneficial. Losing just 5% of body weight can help lower androgen levels, which may reduce excessive hair growth.
Cosmetic hair removal methods address visible hair and can complement medical treatments. Options include:
- Laser Therapy: Trials show that photoepilation can reduce hair by 40% to 80%, depending on the laser type and number of sessions. Laser treatments work best for individuals with dark hair.
- Electrolysis: This method may be more suitable for those with blonde or white hair, as it targets individual hair follicles.
- Traditional Methods: Shaving, waxing, and plucking provide temporary relief and can be used alongside other treatments.
- Combination Treatments: Pairing eflornithine with laser therapy has been shown to improve overall results.

FAQs
What’s the difference between hirsutism and hypertrichosis, and how can I figure out which one I have?
Hirsutism is the term for excessive growth of coarse, dark hair in women, showing up in areas where men usually grow hair, such as the face, chest, or back. This condition is often tied to hormonal imbalances, like those caused by PCOS or other androgen-related disorders. Additional symptoms such as acne, a deeper voice, or irregular menstrual cycles can also signal hirsutism.
In contrast, hypertrichosis refers to excessive hair growth that can occur anywhere on the body in both men and women. Unlike hirsutism, it’s not linked to hormones. It might be present from birth or develop later due to factors like specific medications or underlying medical conditions.
The key to distinguishing between the two lies in the pattern and location of hair growth. Hirsutism typically follows a male-pattern distribution and is hormone-related, while hypertrichosis can appear on any part of the body and doesn’t come with hormonal symptoms. If there’s any uncertainty or unusual symptoms, consulting a healthcare provider is the best way to get a clear diagnosis.
What is the Ferriman-Gallwey Scoring System, and how can it help determine if medical attention is needed for hirsutism?
The Ferriman-Gallwey Scoring System is a tool used to measure hair growth in nine specific body areas that are sensitive to androgens. These areas include the upper lip, chin, chest, and abdomen. Each of these regions is scored on a scale from 0 (no visible hair) to 4 (extensive hair growth), and the scores are then totaled.
If the total score reaches 8 or higher, it usually indicates hirsutism. A score exceeding 15 points to moderate to severe hirsutism, which might warrant a medical evaluation. This scoring system is particularly useful for identifying when excessive hair growth could be tied to underlying issues, such as hormonal imbalances, and helps determine when it’s time to consult a healthcare professional.
What lifestyle changes can help reduce hirsutism, and how do they compare to medical treatments?
Lifestyle adjustments - like maintaining a healthy weight, staying active, and eating a balanced diet - can help lower androgen levels and improve insulin sensitivity. For individuals dealing with conditions like PCOS, where hormonal imbalances are a factor, these changes may help reduce symptoms of hirsutism.
That said, medical treatments often deliver quicker and more noticeable results. Options like anti-androgens (such as spironolactone) or hormonal therapies can directly target the issue. The best results often come from combining these medical treatments with lifestyle changes. While lifestyle tweaks alone might not have the same immediate impact as medication, they contribute to overall well-being and can complement medical treatment plans effectively.
