I recently started using Nioxin hair products. Shortly after useage I started getting headaches every night between (3 &;;;;;; 7 am) I then noticed my blood pressure fluctuating and most recently getting extremely high. I stopped using the products and my headaches diminished and my blood pressure went back to my normal readings. There are no warning labels on your products stating this and if I didn't receive some similar reviews I would not have had any idea. Your products need warnings and side effects
