How Saw Palmetto Works:

  • Decreases DHT levels by inhibiting 5-alpha reductase. 5-alpha reductase (5AR) converts testosterone (found in both men and women, more so in men) to DHT or dihydrotestosterone.
  • Inhibit binding of DHT to receptors
  • Promote DHT breakdown

The evidence in androgenic alopecia (AGA):

Research in to hair loss prevention and hair growth is ongoing and promising (click here) and here, especially in the area of Androgenic Alopecia (AGA). In AGA one of the main culprit is increase DHT levels.

The main concept behind the hair loss treatment (AGA) is its ability to block an enzyme (5-alpha-reductase) which converts testosterone to DHT. Increase DHT levels increases prostate size in men and increase levels result in hair loss.  One of the explanation is that DHT attaches to androgenic receptors on follicles and result in their miniaturization (click here).
