Query: don't believe everything you read

I've used the whole Nioxin system (#1) for about 2 years now. I finally gave up and stopped. After all this time and money spent, I have no perceived increase in hair density like the bottle claims and all it has done is made my hair fall out even more! I know most people say it falls out at the beginning of use because its dead hair and takes time to improve the scalp environment but my hair would fall out after Nioxin use every single time up until today. I'm now going back to regular shampoos and conditioners so my hair will stop falling out! Don't believe in this product... its a rip off. I also confirmed with 2 different Dermatologists that its all a gimmick and does nothing! That, with my own personal experience is definitely proof enough that its a waste of money! Don't waste your time and money people.
