Hirsutism Excessive Hair Women

Overview

Hirsutism is the growth of thick, dark hair in women in places where men usually grow hair, such as the upper lip, chin, chest, belly, back, or inner thighs. It is different from having fine, light hair all over the body, which is common and usually not a health problem. Hirsutism is often linked to hormones called androgens, but not every woman with extra hair has a hormone problem. A healthcare provider can help find the cause and discuss options.

Hirsutism is common. It affects roughly 5 to 10 in every 100 women of reproductive age in many studies, though numbers vary by population and how hair growth is measured.

It can affect women of any age after puberty, but it often starts in the teens or twenties. It is more common in women with polycystic ovary syndrome (PCOS), a common hormone condition, and in those with a family history. It can also occur after menopause or with certain medicines.

Symptoms

Common symptoms

• Thick, dark, coarse hair on the upper lip, chin, cheeks, neck, chest, belly, back, upper arms, or thighs
• Hair that is darker or coarser than before
• Acne or oily skin
• Irregular periods or no periods
• Weight gain, especially around the waist
• Trouble getting pregnant
• Thinning hair on the scalp in a male pattern

Symptoms in children

• Early growth of pubic or underarm hair
• Body odor
• Acne
• Rapid growth
• A deep voice

Symptoms in older adults

• New or quickly worsening hair growth after menopause
• Hair growth with a deep voice, scalp balding, or enlarged clitoris
• Hair growth with high blood pressure, easy bruising, or purple stretch marks

Causes

Main causes

• Polycystic ovary syndrome (PCOS), a common hormone condition
• Higher levels of male-type hormones called androgens
• Adrenal gland conditions that make extra hormones
• Ovary conditions that make extra hormones
• Medicines that can affect hair growth or hormones
• Family history and ethnicity, which can affect how hair grows
• Insulin resistance, where the body does not respond well to insulin
• Sometimes no clear cause is found

Risk factors

• Having PCOS
• Having a family member with hirsutism or PCOS
• Being overweight or having insulin resistance
• Taking certain medicines
• Having a hormone condition affecting the adrenal glands or ovaries
• Starting puberty or going through menopause

When to see a doctor

See a doctor urgently if:

• You notice sudden voice changes, enlarged clitoris, rapid hair growth, or male-pattern balding
• You have severe pelvic or belly pain
• You feel very weak, dizzy, or confused
• You have high blood pressure with weight gain, easy bruising, or purple stretch marks

Book a routine appointment if:

• You have extra hair that bothers you
• Your periods are irregular or absent
• You have acne, weight gain, or trouble getting pregnant
• Hair growth is getting worse
• You take a medicine and wonder if it is linked
• You feel low or anxious about your appearance

Diagnosis

Your clinician will ask about your hair growth, periods, medicines, and family history, and examine the areas with extra hair. They may ask about other signs like acne, voice changes, or weight changes. The first step is to look for a cause and to decide whether tests are needed. You do not need to remove hair before the visit unless you want to; photos can help track changes.

Tests that may be done

• Blood tests to check hormone levels
• Blood tests to check blood sugar and cholesterol
• A pelvic ultrasound to look at the ovaries
• Imaging tests if a tumor is suspected, though this is uncommon

What to expect at your appointment

The visit is private and respectful. Your clinician should explain what they are checking and why. Some results take a few days. You can ask questions and talk about your goals, including hair removal, periods, fertility, and how you feel.

Treatment

Treatment depends on the cause, your symptoms, and what matters to you. Options include hair removal, skin care, lifestyle steps, and medicines that affect hormone levels or hair growth. It can take several months to see a change in hair, so patience and a clear plan help. Always talk with your healthcare provider before starting any treatment.

Self-care at home

• Choose hair removal that suits your skin: shaving, plucking, waxing, trimming, or hair-removing creams
• Test hair-removing creams on a small area first
• Be gentle to avoid ingrown hairs and irritation
• Consider bleaching for dark hair
• Keep skin clean and moisturised
• Use sun protection if hair removal makes skin sensitive
• Track your cycle and symptoms to share with your clinician
• Avoid plucking sore, red, or infected areas

Medical treatments

Treatment depends on the cause and your goals. A clinician may suggest hormonal medicines that reduce male-type hormone levels or block their effects, a prescription skin cream that slows hair growth, or procedures such as laser therapy or electrolysis. They may also treat an underlying condition, such as PCOS or insulin resistance, using general lifestyle and medical approaches. No medicine is right for everyone, so discuss risks, benefits, and fertility plans with your healthcare provider.

When is surgery considered?

Surgery is rarely needed. It may be considered if tests show a tumor in an adrenal gland or ovary that is making hormones. This is uncommon. For typical hirsutism, treatment does not usually involve surgery.

Living with this condition

Extra hair can affect how you feel in social situations, at work, or in relationships. It can help to have a routine that feels manageable, such as shaving or trimming on set days, and to remind yourself that hirsutism is a medical issue, not a personal failing. Tell your clinician if hair removal is painful, causes scars, or takes too much time.

Lifestyle tips

• Keep a healthy weight if it is right for you
• Stay active
• Get enough sleep
• Manage stress
• Avoid smoking
• Treat other health conditions
• Ask a pharmacist before using new hair removal products

Diet and exercise

A balanced diet and regular movement can improve insulin resistance and PCOS symptoms. There is no special diet that cures hirsutism. Aim for meals with vegetables, protein, and whole grains, and choose activity you enjoy. Ask your clinician for personalised advice if you have PCOS, diabetes, or weight concerns.

Mental health and emotional wellbeing

Hirsutism can cause shame, anxiety, low mood, or depression. These feelings are valid and worth discussing. If you feel overwhelmed or have thoughts of harming yourself, contact your local crisis support or emergency services right away. You deserve support.

Prevention

Hirsutism cannot always be prevented, especially when it runs in families or is linked to PCOS. You can help manage it by treating underlying conditions, keeping a healthy lifestyle, and asking about medicines that may affect hair growth. Early help can make symptoms easier to manage.

Vaccines

There is no vaccine for hirsutism.

Screening programmes

If you have PCOS, insulin resistance, or take medicines that affect hormones, your clinician may check blood pressure, blood sugar, and cholesterol regularly. Ask what screening is right for you.

Complications

If left untreated

• Emotional distress, anxiety, or depression
• Skin irritation, ingrown hairs, or scarring from hair removal
• If PCOS is the cause, a higher risk of type 2 diabetes, heart disease, and fertility problems
• Rarely, a hormone-producing tumor that needs treatment

Long-term outlook

Most women with hirsutism can manage the hair growth and any underlying condition. Improvement is often slow, taking 6 to 12 months with hormonal treatment, so give it time. Many people find a combination of hair removal, lifestyle steps, and medical care that works for them.
