What Is Hair Loss and Why Does It Happen?

Losing 50 to 100 strands of hair a day is completely normal.
But if you're seeing more hair fall than usual—or noticing thinning spots—it could be a sign of a deeper issue.

Hair loss (also known as alopecia) can be caused by a mix of factors like genetics, hormones, stress, diet, lifestyle, and even environmental conditions.


Hair Loss by Age: What to Expect

🔹 In Your 20s–30s
More young people are experiencing early hair loss due to stress, poor diet, and irregular sleep patterns.

🔹 In Your 40s–50s
This is when hereditary or hormonal hair loss (like male or female pattern baldness) starts to show more noticeably.

🔹 In Your 60s and Beyond
As we age, hair follicles shrink and regeneration slows down, causing gradual thinning.


Hair Loss by Gender: Men vs. Women

Male Pattern Baldness

  • Main Cause: DHT (a form of testosterone), genetics

  • Pattern: Receding hairline (M-shape), thinning at the crown

  • Treatment: Finasteride, Dutasteride, Minoxidil, Hair Transplant

Female Hair Loss

  • Main Cause: Hormonal changes (pregnancy, menopause), thyroid issues

  • Pattern: Widening part line, general thinning at the top

  • Treatment: Minoxidil, hormonal evaluation, scalp treatments, supplements


Regional Differences in Hair Loss

🔸 South Korea:
Hair loss is on the rise from the 30s, largely due to stress and genetics.

🔸 USA:
Over 60–70% of men experience hair loss; there’s more awareness and access to treatment clinics.

🔸 Europe:
Countries like Germany and the Czech Republic report higher genetic predispositions to baldness.

🔸 Southeast Asia:
Historically lower hair loss rates, but urban stress and lifestyle changes are causing an uptick.


Ethnicity & Hair Loss Patterns

  • Caucasians: Highest overall hair loss rates (up to 80%)

  • Asians: Moderate rates, typically thinning at the crown

  • Africans: Lower rates, but more prone to scarring alopecia when it does occur


Easy Tips to Prevent Hair Loss
