Because rather than simply "cleaning" or "purifying" the scalp, Profollica? uses the very latest in medical scientific research to deal with the root cause of men's hair loss: excess DHT (dihydrotestosterone)!
DHT literally poisons the hair follicles on top of your head causing them to shrink... and then disappear!
That's why, as your first line of defense, Profollica? actually discourages the excess production of DHT, the #1 enemy of hair regrowth!
