Overview

Androgenetic alopecia (AGA) is the most common cause of hair loss worldwide, affecting up to 50% of men by age 50 and a significant proportion of women. It is hereditary, driven by dihydrotestosterone (DHT). Men develop a receding hairline and crown thinning; women experience diffuse thinning over the scalp top with the frontal hairline usually preserved.

Symptoms

• Men: receding hairline at temples, crown thinning, gradual progression to baldness
• Women: diffuse thinning on top of scalp, widening central part, maintained frontal hairline
• Hair miniaturises over time before follicles stop producing

Causes & Risk Factors

• Genetics: multiple genes from both sides of the family
• DHT binds to follicle receptors causing miniaturisation and cessation
• In women: hormonal changes from menopause, PCOS, or thyroid dysfunction

Complications

• Progressive permanent hair loss if untreated
• Reduced confidence, anxiety, and social withdrawal

Diagnosis

Clinical exam and dermoscopy (trichoscopy) showing follicular miniaturisation. Blood tests in women: hormones, thyroid, iron, vitamin D.

Treatment

• Minoxidil (topical or oral) — most widely used; prolongs hair growth phase
• Finasteride (oral, men only) — blocks DHT; highly effective
• Spironolactone or combined oral contraceptives for hormonal AGA in women
• PRP injections; low-level laser therapy (LLLT)
• Hair transplant surgery (FUE/FUT) — permanent solution; very popular in Kuwait and GCC

Prevention

• Begin treatment as soon as thinning is noticed — early intervention is most effective
• Manage hormonal conditions in women; avoid tight hairstyles and heat styling
• Maintain diet rich in iron, protein, and zinc
