Saw palmetto extracts and supplements work as hair loss remedies because they keep testosterone levels balanced.

An enzyme in Saw Palmetto converts the male hormone testosterone into DHT — a sex steroid and androgen hormone. While DHT is important because it plays a role in male development, it also contributes to many common health issues in men, such as loss of libido, an enlarged prostate and hair loss. By taking saw palmetto supplements or using the extract of this beneficial plant, you inhibit the production of this hormone and avoid these issues that are seen in middle-aged and older males.
