I am a rather skeptical person. When I was introduced to Revivogen, I must admit that I was hesitant to use the product. i had tried many other products and incurred thousands of dollars in costs with no results. however, afrter using Revivogen, i noticed dramatic results in a few months. I received nurmerous compliments about the thickness of my hair. My greatest insecurity was my hair loss problem. Now that I have found this product, worries about hair-loss no longer trouble me.
