Approximately 85% of men experience significant hair thinning by age 50, and the vast majority of cases are androgenetic alopecia — male pattern baldness.
Signs of Genetic Hair Loss
Genetic hair loss follows a predictable pattern: receding hairline at the temples forming an 'M' shape and/or thinning at the crown. It's gradual, progressive, and often mirrors patterns in your family.
Other Causes to Rule Out
Not all hair loss is genetic. Stress-related telogen effluvium causes diffuse thinning and is usually temporary. Nutritional deficiencies, thyroid disorders, and certain medications can also cause hair loss.
When to Start Treatment
The earlier you start, the better. Hair loss treatment is significantly more effective at maintaining existing hair than regrowing lost hair. A same-day online consultation can get you started.
