Hirsutism

What is Hirsutism?

Hirsutism is the excessive growth of dark, coarse hair in women in areas where men typically grow hair, such as the face, chest, back, and arms. It is often linked to hormonal imbalances, particularly androgens (male hormones).

Causes

Hormonal / Medical Causes

• Polycystic Ovary Syndrome (PCOS) → most common cause in women.
• Adrenal disorders → Cushing’s syndrome, congenital adrenal hyperplasia.
• Androgen-secreting tumours → rare, but can cause sudden, severe hair growth.
• Hormonal medications → some steroids or anabolic hormones.

Genetic / Ethnic Factors

• Family history → certain ethnicities may naturally have thicker or darker hair.

Other Causes

• Ageing and menopause → hormonal shifts may increase hair growth.
• Idiopathic hirsutism → normal hormone levels but excessive hair growth, usually mild.

Symptoms / Appearance

• Dark, coarse hair in a male-pattern distribution.
• Hair growth may appear gradually or suddenly, depending on the cause.
• May be accompanied by other hormonal signs: acne, irregular periods, voice deepening.
• Can affect self-esteem and body image.

Treatments

• Cosmetic / Temporary Hair Removal
• Shaving, waxing, threading, plucking → temporary solutions.
• Depilatory creams → dissolve hair at the skin surface.
• Bleaching → lightens hair for cosmetic purposes.
• Medical / Hormonal Treatments
• Topical eflornithine cream → slows facial hair growth.
• Oral anti-androgens → spironolactone, cyproterone acetate.
• Hormonal therapy → oral contraceptives to regulate androgen levels.
• Permanent Hair Reduction
• Laser hair removal → long-term reduction.
• Electrolysis → destroys hair follicles for permanent removal.
• Addressing Underlying Causes
• Treat PCOS, adrenal disorders, or thyroid issues to reduce hair growth.
• Regular monitoring of hormonal levels is indicated.

FAQs

Q1. Is hirsutism normal?

Q2. Can hirsutism be permanently treated?
Yes, laser hair removal and electrolysis are the most effective long-term options.

Q3. Does shaving make hair grow back thicker?
No, shaving does not affect hair thickness.

Q4. When should I see a doctor?
If hair growth is sudden, severe, or accompanied by other hormonal symptoms like irregular periods, acne, or voice changes.

Q5. Can diet help with hirsutism?
Diet alone won’t stop hair growth, but weight management and controlling insulin resistance (especially in PCOS) can help reduce symptoms.
