I STILL HAVE HAIR BECAUSE OF NIOXIN!

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.

Great Shampoo

Even though it is expensive, it is worth it. It thickens your hair and leaves it soft and clean. It has a fresh minty scent, and this size bottle lasts around 3 months. I highly recommend trying it.
