Nioxin System 4 Cleanser Shampoo 1 Liter/33.8Oz

I have been using this shampoo for about 7 years. It works. I am 80 years old. Before I started using this shampoo, my hair was falling out at an alarming rate. Every time I washed my hair, I found a clump of hair. Now I may find one or hairs and sometimes none. A bottle last for a long time. You only need to use a little. It lathers up with just a little bit. The price has double I just paid as much for a 33 oz bottle of shampoo as I did for BOTH shampoo and conditioner, when I first started using it. But, for mer it is well worth the money.
