I am a 47 year old female and was on dialysis for about a year before getting a kidney transplant. While on dialysis my hair started coming out and I could see it was thinning at my part. Someone told me about Nioxin products so I bought the whole package with the shampoo, conditioner and another product to put drops directly on my scalp. First of all I could hardly stand the medicinal smell. It was so strong it made my eyes water. I used the products for a few months. I did notice a little less hair falling out, but I didn't see new hair growth, and the smell was just more than I could smell. I got sick easily anyway and the smell would make me feel physically ill. I would have continued to use the product, even though the smell was so bad, because I WAS losing less hair but I got a kidney transplant and don't have the thinning problem now as I did before. If you can stand a very medicinal smell while washing your hair, and even after it is dried, it does seem to help with thinning hair and is definitely worth a try.
