I am currently using provillus for my hair loss problem, been on provillus for five weeks and i want to say there is a major improvement on my hair. I got the pkg which include both the vitamins and the topical. I use it one time every evening. The area which i was balding in was the top middle portion of my head, not certain why cause others in my family is loosing hair excpet me so its not genetic. I have hair regrowth in that balding area, few strands are coming up and my family says it is so much better than before. I still have time to go, and i believe provillus can treat my baldness. So far five weeks and i do see large improvements so my hope is up. So from my point of view, provillus works and have no side effects.
