What Actually Causes Hair Loss in Men
Genetics drive most of it, but not all of it. Knowing which factors are at play changes what you can do about it.
What this is
Most male hair loss comes down to genetics and hormones, but other factors can contribute or speed it up, and a few causes are worth ruling out. This page explains the main reasons men lose hair, why most of it traces back to inherited sensitivity to DHT, and which contributing factors are within your control. The goal is clarity about your specific situation, not a single blanket answer.
Why it happens
In most men, hair loss is driven by genetically inherited sensitivity to DHT, which gradually shrinks affected follicles. Other factors such as stress, nutrition, certain conditions, and medications can add to or accelerate loss in some people.
Common causes
Genetics and DHT sensitivity, aging, hormonal factors, stress, nutritional deficiencies, certain medical conditions, and some medications can all play a role.
Possible paths forward
Identifying whether your loss fits the common genetic pattern or points to something else; seeing a provider to rule out treatable contributors; addressing controllable factors like stress and nutrition; and discussing evidence-based options.
