How Saw Palmetto prevents hair loss?
In order to understand the role of saw palmetto in preventing hair fall its essential to understand the root cause of hair fall caused by DHT first. Testosterone is a powerful and essential sex hormone. In men it is the main sex hormone and also an anabolic steroid. Dihydrotestosterone (DHT) is a by-product of testosterone and is an essential androgenic hormone responsible for the formation of male primary sex characteristics. Testosterone converts to DHT with the aid of the enzyme 5-alpha-reductase. It is scientifically proven that DHT is the root cause of hair loss in adult men leading to a condition known as androgenic alopecia generally termed as male pattern baldness. Although the exact mechanism by which DHT leads to male pattern baldness is not fully understood as yet but it initiates a process of follicular miniaturization in which the width of hair shaft starts reducing gradually making hairs thinner. This process of thinning continues until hair actually falls.
