Male Pattern Baldness: Causes, Stages & Treatment

What Is Male Pattern Baldness?

Male pattern baldness (androgenetic alopecia) is the most common type of hair loss in men, affecting about 50% of men by age 50. It follows a predictable pattern: receding hairline and thinning at the crown. While it is primarily genetic, effective treatments can slow loss and promote regrowth.

Common Causes of Male Pattern Baldness

• Genetics (primary factor)
• DHT (dihydrotestosterone) hormone
• Aging
• Hormonal changes
• Stress (can accelerate)
• Nutritional deficiencies

When to See a Doctor

See a dermatologist if hair loss is sudden, patchy, or rapid. Also seek evaluation if you want to explore treatment options, as earlier treatment is more effective.

Warning Signs That Need Immediate Attention

Frequently Asked Questions

Can male pattern baldness be reversed?

Partially. Minoxidil can regrow some hair and slow loss. Finasteride blocks DHT and is the most effective oral medication. Results are best with early treatment. Hair transplants offer permanent solutions for advanced loss.

At what age does male pattern baldness start?

It can begin as early as the late teens but typically becomes noticeable in the 20s-30s. By age 50, about half of men have significant hair loss. The earlier it starts, the more aggressive it tends to be.

Does wearing hats cause baldness?

No, wearing hats does not cause baldness. This is a common myth. Male pattern baldness is determined by genetics and hormones, not by hat-wearing or hair styling habits.

Is finasteride safe?

Finasteride is FDA-approved and safe for most men. Side effects (sexual dysfunction) occur in 1-2% of users and typically resolve after stopping. Discuss risks and benefits with your doctor.

How much does hair loss treatment cost?

Minoxidil costs $15-$50 monthly. Finasteride costs $10-$30 monthly. PRP therapy costs $500-$2,000 per session. Hair transplants cost $4,000-$15,000. OpenMyPro helps you find affordable hair loss care.
