How does it work

What makes this product so good?  How does it work?

Shapiro MD products have received 2 patents for their unique combination of naturally occurring DHT blocking ingredients.  DHT (dihydrotestosterone) is widely believed to be the root cause of hair thinning and hair loss. The more DHT is present in the hair follicle, the thinner the hair becomes until eventually it falls out. All 3 of the ingredients in the Shapiro MD Shampoo and Conditioner have been shown in clinical studies to block DHT from entering the follicle and thus allowing hair to remain thicker, fuller and healthier.
