How does hair loss occur?
Baldness is largely the result of certain hormones interacting over time with those hair follicles that are vulnerable to their effects.
For men who are experiencing thinning hair, their follicles on the top of the head are genetically vulnerable to baldness. Over time, these genetically vulnerable follicles are acted upon by the hormone DHT. This hormone binds with the receptor sites of these vulnerable follicles and causes a miniaturization of the hair shaft and follicle over time.
This process of hair loss gradually breaks down the follicles' ability to grow healthy, thick hair. The resulting baldness is commonly known as "Male Pattern Baldness"
