I am loving my results with the Nioxin Scalp Therapy System 1 Shampoo and Conditioner Treatment. I found it at Costco (Western Canada) for $39.99 which is a great price. Very pleased with how it makes my hair feel and look as well. It also gives your scalp a good cleansing with a fresh tingling feeling. If you have thinning looking hair due to stress or "gasp" menopause (lol!) I would definitely recommend the System 1 Duo.
