What are the common patterns of hair loss in men?

Reviewed by Yoshinori Abe, MD

Internal Medicine

Common patterns of hair loss in men include a receding hairline, thinning at the crown, and gradual balding on the top of the head. These patterns, often called male pattern baldness (androgenetic alopecia), are typically caused by a combination of genetic predisposition and hormonal factors—specifically, sensitivity to dihydrotestosterone (DHT). However, not all hair loss is genetic. Stress, nutritional deficiencies, thyroid issues, and certain medications can also trigger shedding, which is why identifying the underlying cause matters.

Because hair loss can stem from many different conditions—some treatable, some progressive—understanding what's driving your symptoms is the critical first step toward effective care. A free, instant, online symptom check can help you quickly assess your situation, explore possible causes, and decide on the right next steps, whether that's a lifestyle adjustment, a specialist visit, or simply peace of mind.

Explanation

Male pattern hair loss usually follows a recognizable pattern of receding hairline and thinning hair on the crown. This condition is mostly influenced by genetics and hormones, particularly the hormone dihydrotestosterone (DHT). Over time, DHT causes hair follicles to shrink, leading to shorter and thinner hair until the follicles stop producing hair altogether.

Common Patterns:

Receding Hairline: The hairline gradually moves back, forming an "M" shape.
Thinning on the Crown: Hair becomes thinner on the top of the head, often leading to a bald spot.
Complete Baldness: In some cases, the hair loss progresses to complete baldness on the top while hair remains on the sides and back.

Factors:

Genetic Predisposition: Family history plays a significant role in male pattern hair loss.
Hormonal Influence: DHT, a derivative of testosterone, is a key factor in the miniaturization of hair follicles.

Understanding these patterns helps in recognizing the condition early and considering treatment options.
