Hirsutism
What is Hirsutism?
Hirsutism is a condition where women develop excess hair growth in a male-pattern distribution. This means thick, dark hair appears on the face, chest, back, and abdomen. The condition affects about 5 to 10 percent of women of reproductive age.
Hirsutism happens when the body produces too much of male hormones called androgens. These hormones include testosterone and DHEA-Sulfate. The excess androgens trigger hair follicles to grow coarse, dark terminal hairs instead of fine, light vellus hairs.
While hirsutism itself is not dangerous, it often signals an underlying hormonal imbalance. Many women with hirsutism also have polycystic ovary syndrome, or PCOS. Understanding your hormone levels helps identify the root cause and guide treatment.
Symptoms
- Thick, dark hair on the face, especially upper lip and chin
- Excess hair growth on the chest, back, or abdomen
- Hair growth on the inner thighs and buttocks
- Acne or oily skin
- Deepening of the voice
- Increased muscle mass
- Irregular or absent menstrual periods
- Male-pattern baldness or thinning hair on the scalp
Some women with mild hormonal imbalances may only notice facial hair, while others experience more widespread symptoms. The severity varies based on genetics and how sensitive hair follicles are to androgens.

Causes and risk factors
Hirsutism develops when the ovaries or adrenal glands produce too much testosterone or DHEA-Sulfate. Polycystic ovary syndrome causes about 70 to 80 percent of hirsutism cases. In PCOS, the ovaries make excess androgens and develop small cysts. Other causes include congenital adrenal hyperplasia, Cushing syndrome, and androgen-secreting tumors, though these are less common.
Certain medications can trigger hirsutism, including anabolic steroids, danazol, and some hormones. Insulin resistance and obesity increase androgen production and worsen symptoms. Ethnicity also plays a role, as women of Mediterranean, Middle Eastern, and South Asian descent naturally have more body hair. Family history matters too, since hirsutism often runs in families.
How it's diagnosed
Doctors diagnose hirsutism by evaluating hair growth patterns and measuring androgen levels through blood tests. A physical exam assesses the amount and distribution of excess hair using a scoring system. Blood work checks total testosterone, free testosterone, bioavailable testosterone, and DHEA-Sulfate levels.
Testosterone levels above 50 to 60 ng/dL suggest hyperandrogenism, which means excess male hormones. Free testosterone is especially important because it measures the active hormone directly responsible for hair growth. Rite Aid offers testing for all key androgens that cause hirsutism, including testosterone and DHEA-Sulfate. Additional tests may check for PCOS, thyroid problems, or adrenal disorders.
Treatment options
- Weight loss of 5 to 10 percent can significantly reduce androgen levels in women with PCOS
- Anti-androgen medications like spironolactone block testosterone effects on hair follicles
- Birth control pills lower androgen production and regulate menstrual cycles
- Metformin improves insulin sensitivity and may reduce androgen levels
- Hair removal methods include laser therapy, electrolysis, shaving, waxing, and depilatory creams
- Reducing refined carbohydrates and sugar helps manage insulin resistance
- Regular exercise improves hormone balance and insulin sensitivity
- Stress management supports healthy cortisol and hormone levels

Frequently asked questions
Polycystic ovary syndrome causes 70 to 80 percent of hirsutism cases. PCOS triggers the ovaries to produce excess testosterone and other androgens. These male hormones stimulate hair follicles to grow thick, dark hair in male-pattern areas like the face, chest, and back.
Blood tests for hirsutism measure total testosterone, free testosterone, bioavailable testosterone, and DHEA-Sulfate. Free testosterone is the most sensitive marker because it measures the active hormone directly causing excess hair growth. Testosterone levels above 50 to 60 ng/dL suggest hyperandrogenism and help distinguish between PCOS, adrenal causes, and idiopathic hirsutism.
Hirsutism cannot always be cured, but it can be managed effectively with treatment. Addressing the underlying hormonal imbalance through medications and lifestyle changes reduces new hair growth over time. Existing hair may need removal through laser therapy, electrolysis, or other methods since hormone treatment does not reverse hair that already developed.
Most women see improvement in 6 to 12 months after starting treatment. Hair follicles have a slow growth cycle, so reducing androgen levels takes time to affect new hair growth. Consistent treatment with anti-androgens or birth control pills gradually decreases hair thickness and growth rate over several months.
Yes, weight loss of just 5 to 10 percent can significantly reduce androgen levels in women with PCOS and insulin resistance. Excess body fat increases insulin levels, which stimulate the ovaries to produce more testosterone. Losing weight improves insulin sensitivity and lowers androgen production, which reduces hair growth over time.
Hirsutism usually signals a hormonal imbalance rather than a life-threatening condition. However, it often occurs with PCOS, which increases the risk of type 2 diabetes, heart disease, and infertility if left untreated. Rarely, very high androgen levels may indicate an adrenal or ovarian tumor that requires immediate medical attention.
Hirsutism is male-pattern hair growth in women caused by excess androgens. It appears on the face, chest, back, and abdomen. Hypertrichosis is excess hair growth all over the body that is not hormone-related and can affect men, women, and children equally.
Yes, combination birth control pills are often the first treatment for hirsutism. They lower androgen production by the ovaries and increase a protein that binds testosterone, making less free testosterone available. Most women see gradual improvement in hair growth within 6 to 12 months of starting birth control.
Spironolactone is an anti-androgen medication that blocks testosterone from binding to receptors in hair follicles. This prevents androgens from stimulating excess hair growth. Spironolactone takes 3 to 6 months to show results and works best when combined with birth control pills for women of reproductive age.
Yes, eating a low-glycemic diet with reduced refined carbohydrates and sugar helps manage insulin resistance. Lower insulin levels decrease androgen production by the ovaries. Focus on whole foods, lean proteins, healthy fats, and plenty of vegetables to support hormone balance and reduce hirsutism symptoms.
