No, I hadn't heard of Nano shampoo! Now I am thinking of the old "Mork and Mindy" TV show of the 70's where Mork goes around saying, "Nano, nano!" (you guys are probably too young to remember that!)
Interesting that the site seems to hint that Nioxin is good for stimulating the scalp and perhaps thickening the hair, whereas they state that Nano might encourage regrowth, too! That would be wonderful!
I have been using Nioxin for almost a year, now. My hair loss seemed to slow down just a bit, but it is still hard to tell. About a month ago, my hairdresser asked if I was using the Nioxin "hair vitamins", too. I told her I wasn't aware they had any! So, I bought a bottle and have been taking them faithfully. I figured it couldn't hurt as I wasn't taking any vitamin and they have B Vitamins and Biotin, which I hear is good for hair, although not in large amounts. I am hoping that the vitamins, together with the shampoo will help.
My hairdresser went to a special Nioxin seminar and, like yours claims it is wonderful stuff. Now, that might very well be true, but then it makes me wonder if it was the type of seminar that encourages them to push the product because of the money the company will make off their clients?
I don't want to be a pessimist, but I am wondering, at least in my case, if anything can really help, since my hair loss is genetically linked, too (all the men in my family are bald and I have seen pics of ancestors and the women get bald, too!) However, hope springs eternal!
Thanks for posting about this product. I will look into this.
